(Fig.1) Quantum mechanics obstructing science needs fictional targets and hyped news
The 1st, 7-8th, paragraphs of this hyped news say
"Their findings, published in the journal Nature Nanotechnology, could (= just speculation ) also support the development of more efficient lasers, which are used in fields ranging from medicine to manufacturing (= overhype. Actually, this research mentioned nothing about practical use such as efficient laser, medicine )."
"To create their device, the researchers grew ultrathin plates of halide perovskite, a crystal made of cesium, lead, and chlorine, and etched a polymer on top of it with a pattern. They sandwiched these crystal plates and polymer between sheets of various oxide materials, eventually forming an object about 2 microns thick"
"When the researchers shined a laser light on the device, a glowing triangular pattern appeared at the interfaces designed in the material. This pattern, dictated by the device's design, is the result of topological characteristics of lasers."
↑ Just saying the vague "topological characteristic", No mention of practical use nor clarifying the true physical mechanism.
↑ This research paper's abstract-upper and last parts say
"Exciton-polaritons, that is, the hybrid (fictional) quasiparticles of excitons and photons in semiconductor microcavities, have been proposed as a tunable nonlinear platform for emulating topological phenomena (= vague topological, again )."
"The geometric parameters and material composition of our nonlinear many-body photonic system platform can in principle be tailored to study topological phenomena of other interquasiparticle interactions."
↑ Just mentioning ambiguous (unphysical) "topological" and fictional quasiparticle model, No mention of practical use.
↑ This research's supplementary information ↓
p.3(or p.2), p.5(or p.4) p.9(p.8), p.11(p.10) used fictional quasiparticle model such as exciton, polariton with fake effective masses to explain the detected light interaction with the material (= photoluminescence or PL in p.10-Fig.5 ).
↑ No real particle picture nor quantum mechanical prediction.
This reseach is useless except for publishing paper in journals.
The 3-5th, 11-12th, 18-19th paragraphs of this hyped news say
"Now a Caltech team has made a key discovery that helps simplify such calculations, speeding them up by a factor of 50 or more while maintaining accuracy. As a result, it is possible to compute electron interactions in more complex materials and devices (= false, this research is just about fictional quasiparticle, Not real electrons )"
"Their approach simplifies the dense computational matrices used to represent the interactions that take place in a material between electrons and atomic vibrations (or phonons, which can be thought of as individual units of vibrational energy = unreal phonon quasiparticle model )."
"the new method allows them to use only 1 to 2% of the data typically used to solve such problems, greatly accelerating calculations (= just artificially choosing only convenient data parameters is Not quantum mechanical prediction )"
"His group's approach is based on applying a method called singular value decomposition (SVD) to the electron–phonon (= unreal quasiparticle ) interactions in a material"
"These real positive numbers are called singular values and rank the fundamental interactions in order of importance. Then the program can eliminate all but a few percent of the interactions in each matrix, leaving only the leading singular values, a process that makes the determination cheaper (= just artificially picking up some interactions is Not quantum mechanical prediction )"
"the researchers show that the compression of matrices related to electron–phonon interactions using the SVD method provides accurate results for various properties of materials researchers might want to calculate, including charge transport, spin relaxation times, and the transition temperature of superconductors (= based on artificially-created fictitious phonon quasiparticle model )."
" Bernardi says that this will (= just speculation, still useless ) enable users in the scientific community to predict material properties associated with electron–phonon interactions significantly faster (= it is meaningless to try to predict illusory phonon quasiparticle behavior )."
↑ This research tried to explain some material's (useless) parameters such as fictional phonon quasiparticle by quantum mechanical unphysical one-pseudo-electron DFT model with artificially chosen pseudo-potential.
No quantum mechanical prediction. No practical use.
↑ This research paper ↓
p.1-right-2nd-paragraph says "Focusing on electron-phonon (e-ph) interactions (= fictional quasiparticle phonon model )"
p.2-left-1st-paragraph says "interactions need specialized treatments to capture
p.2-right-last-paragraph describes fictional photon quasiparticles and electrons only as nonphysical math operators with No concrete shapes.
p.3-left-last-paragraph says "the resulting curve of error versus number of parameters is the Pareto frontier for modeling e-ph (= electron-phonon ) interactions (= artificial parameters for estimating fictional phonon quasiparticle interaction ). "
p.4-left says " The mobility is overestimated for electrons, and underestimated for hole carriers, despite the accuracy of the low-rank e-ph interactions in silicon (= even artificial model failed to explain experimental results )"
p.5-left-D. says "We also leverage the improved Brillouin-zone sampling technique where only electronic states in a small energy window (0.006 Ry) near the Fermi surface are included in the calculation (= artificially choosing the energy of outer electrons in Fermi level related to these phenomena, which is Not prediction )"
p.9-right-lower-appendix F says "The DFT ground state calculation in graphene uses the local density approximation with a norm-conserving pseudopotential from PseudoDojo. We employ a 90 Ry plane wave kinetic energy cutoff, and a 2.46 Å lattice constant"
↑ Using impractical one-pseudo-electron DFT with artificially-chosen exchange functional, pseudo-potential, cut-off. and lattice constant is Not a quantum mechanical prediction.
↑ As a result, the current science stops progressing in fictional quantum mechanical quasiparticle model and one-pseudo-electron DFT's pseudo-potential with No real atomic shape.
This current impractical mainstream science keeps giving pseudo-leading scientific position to old archaic universities by suppressing real scientific development and free technological competition in all industrial fields, using academic journals as (fictitious) scientific bible, which old fictional restrictive science enables universities to skyrocket tuition limitlessly.
The 2nd-last paragraphs of this hyped news on IBM-Cleveland clinic quantum computing says
"The team's combination of classical and quantum computing methods (= classical computer conducted almost all calculations ) is an essential step for advancing our understanding of protein structures, and how they impact our ability to treat and prevent disease. The team plans (= still useless ) to continue developing and optimizing quantum algorithms"
↑ This research paper ↓
p.12-right-4. says "quantum-classical hybrid workflow", which is substantially a classical computer (= Not a quantum computer ).
p.14-left-last-paragraph says
"We tested steps 1−3 of this workflow on a small, but highly
relevant seven amino acid fragment" ← Just seven amino acids, Not a protein simulation.
p.15-Figure.11-a this research considered only 7 amino acids that used only 7 ~ 10 qubits (= one qubit can take only 0 or 1, so just 7 bitstring ), which is Not a computer at all.
↑ So IBM-Cleveland used a ordinary classical computer for calculating some amino acids, and their impractical (hyped) quantum computer with only 7 ~ 10 error-prone qubits could Not do any meaningful calculations.
The 1-3rd, 6th, 9th, 11th, 17th, 26th, last paragraphs of this hyped news say
"Quantum computers hold the promise of being able to quickly solve extremely complex problems that might (= just speculation ) take the world's most powerful supercomputer decades to crack (= hype )."
"But achieving that performance involves building a system with millions of interconnected building blocks called qubits. Making and controlling so many qubits in a hardware architecture is an enormous challenge (= millions of qubits are needed to build practical quantum computers, which is impossible forever, this 4th-paragraph ) "
"Toward this goal, researchers at MIT and MITRE have demonstrated a scalable, modular hardware platform that integrates thousands of interconnected qubits onto a customized integrated circuit (= this research was just about a vague platform, and they did Not perform any calculations using qubits because of their extremely high error rate )."
"We will (= still unrealized ) need a large number of qubits, and great control over them, to really leverage the power of a quantum system and make it useful. We are proposing a brand new architecture and a fabrication technology that can support the scalability requirements of a hardware system for a quantum computer,"
"Qubits made from diamond color centers are "artificial atoms" that carry quantum information (= just energy levels ). Because diamond color centers are solid-state systems, the qubit manufacturing is compatible with modern semiconductor fabrication processes (= this hackneyed analogy is false ). They are also compact and have relatively long coherence times, which refers to the amount of time a qubit's state remains stable (= actually this research qubit's lifetime in SnV- in diamond was extremely short, only 5ns, which cannot be used as practical bit memory, this p.15-right-1st-paragraph )"
"The conventional assumption in the field is that the inhomogeneity of the diamond color center is a drawback (= even positions of qubits could Not be controlled in this research ) compared to identical quantum memory like ions and neutral atoms. However, we turn this challenge into an advantage by embracing the diversity of the artificial atoms: Each atom has its own spectral frequency (= energy levels ). This allows us to communicate with individual atoms by voltage tuning them into resonance with a laser.. "
"They started by fabricating an array of diamond color center microchiplets from a solid block of diamond. They also designed and fabricated nanoscale optical antennas that enable more efficient collection of the photons emitted by these color center qubits in free space."
"Using this technique, they demonstrated an entire chip with over 4,000 qubits that could be tuned to the same frequency while maintaining their spin and optical properties. They also built a digital twin simulation that connects the experiment with digitized modeling, which helps them understand the root causes of the observed phenomenon and determine how to efficiently implement the architecture (= No mention of what calculation was done in this research which was useless, because this research is about the mere platform, Not about quantum computation )."
"In the future (= still unrealized ), the researchers could boost the performance of their system by refining the materials they used to make qubits or developing more precise control processes"
This research just randomly created SnV- (= tin vacancy ) qubits whose two atomic energy levels were used as a qubit's 0 or 1 state in diamond. Just controlling and preparing each one qubit's state (= some energy level ) caused 10.24% high error rate ( this p.22 ), which was too bad to calculate anything (= so No calculation was done in this research ).
↑ This research paper ( this ↓ ).
p.2-Fig.1c and p.5-Fig.3d show each atomic qubit's two energy levels = ground state (= g ) and excited state (= e ) were used as a qubit's state, and their energy levels (= f or frequency ) could be artificially varied by applied voltage V (= unphysical spin itself was unobservable, only light interacting with atomic energy levels was detectable ).
p.6-Fig.4a shows randomly-distributed atomic qubits interacting with lights (= positions, energies and brightness of individual qubits were random and disorderly, which architecture is useless ).
p.7-right-2nd-paragraph says "The inset reveals the pulse time sequence used for state preparation and measurement. Initially, a green laser resets the SnV− to the negative charge state. Then, we herald the correct spin state of SnV− using a laser pulse resonant with the R↓ transition (= only laser light interacting with energy levels instead of spin was detectable ). We set a signal threshold count Cth, and when the APD (= avalanche photo diode ) time-bin 1 counts exceed Cth, we consider the SnV− spin state to be successfully prepared."
".. we can calculate the spin state preparation and measurement error espam... we can reduce espam (= error rate ) to 3% (= still high ) after post-selection. Although the probability of successful initialization is about 3% (= too low success probability ) in this case, initialization can be attempted multiple times until it is successful"
↑ This means they artificially post-selected (= after repeating ) only correct results (= only 3% showed right results. the remaining 97% qubit results were erroneous and discarded, which method cannot be used for practical calculations, because almost all qubits must be discarded ).
Even after this artificial postselection, the single qubit's state preparation error was 3%, which was still high.
This p.22 showed each single qubit's state preparation error rate (= without artificial postselection ) was as high as 10.24%, which error rate was far worse than the older qubits (= 0.1 % ) and practical computers (= 10-15, this 5th-paragraph ). ← quantum computer research is regressing.
↑ As a result, this research tried to increase the number of qubits disorderly by creating Tin vacancies inside diamond randomly, but each qubit error rate (= 10.24% ) turned out to be far worse than other older qubits, so they could Not perform any quantum computation (= No one-qubit or two-qubit gate operations were done in this research ).
↑ This current impractical mainstream science intended only for publishing papers in journals can give (pseudo-)scientific leading position to old archaic universities by suppressing really-useful science or free technological competition in all industrial fields, and enables universities to skyrocket tuition unlimitedly.
The 1-4th, 6-7th paragraphs of this hyped news say
"In a new paper in Science Advances, researchers at JPMorgan Chase, the U.S. Department of Energy's (DOE) Argonne National Laboratory and Quantinuum have demonstrated clear evidence of a quantum algorithmic speedup for the quantum approximate optimization algorithm (QAOA)." ← false, this research showed No quantum computer's speed-up.
"This algorithm has been studied extensively and has been implemented on many quantum computers. It has potential (= just speculation ) applications in fields such as logistics, telecommunications, financial modeling and materials science."
"This work is a significant step towards (= meaning "still unrealized" ) reaching quantum advantage, laying the foundation for future impact in production."
"The team examined whether a quantum algorithm with low implementation costs could provide a quantum speedup over the best-known classical methods. QAOA was applied to the Low Autocorrelation Binary Sequences problem or LABS (= this QAQA is Not genuine quantum but hybrid optimization method using also classical computers, this a rough overview ). The study showed that if the algorithm was asked to tackle increasingly larger problems, the time it would take to solve them would grow at a slower rate than that of a classical solver."
"The large-scale quantum circuit simulations efficiently utilized the DOE petascale supercomputer Polaris located at the ALCF (= so this research used "classical supercomputer" to simulate quantum computer, it is Not a quantum computer itself, so No quantum computer speed-up was proved in this research )."
"To take the first step toward (= meaning still unrealized ) practical realization of the speedup in the algorithm, the researchers demonstrated a small-scale implementation on Quantinuum's System Model H1 and H2 trapped-ion quantum computers. Using algorithm-specific error detection (= Not error-correction, but just illegitimate post-selection ), the team reduced the impact of errors on algorithmic performance by up to 65% (= still error-prone )."
This research's illusory quantum speed-up estimation was based on classical supercomputer simulation of an ideal imaginary quantum computer (= instead of using the present error-prone quantum computers, so No proof of quantum-speed-up, this 5-6th-paragraphs ).
They used only a very small number of unstable qubits (= only 18 ion qubits or just 18 bitstring; each ion's two energy levels were used as a qubit's 0 or 1 state ) that could Not give right answers at all due to their large numbers of errors, which was completely useless, No quantum speed-up.
↑ This research paper ↓
p.3-right-3rd-paragraph says "We will refer to CMF (= merit factor ) as the "QAOA energy" as a shorthand. The second figure of merit is the probability of sampling the exact optimal solution, denoted by popt (= both these merit factor CMF and popt are related to probabilities of successfully obtaining exact optimal solution )"
p.5-right says "We note that the merit factor (= success rate ) drops quickly for larger N (= number of qubits ) and is approaching random guess (= random guess is a wrong disorderly answer ) because of experimental imperfections (= errors, noise ) "
p.5-Fig.4-(C) says " Experimental results up to 18 qubits (= N = 18 ) on a trapped-ion quantum device (H1-1) with QAOA. ← C-graph shows this H1-1 with only N = 18 ion qubits approached the mere random guess or wrong answers (= low CMF ) due to their high error or noise rate compared to the noiseless classical computer's simulator ( this 5th-paragraph )"
p.5-right-last~p.6-left says ".. We also note that at this scale LABS is easy for classical heuristics, which obtain optimal merit factors in < 1s (= only N = 18-ion-qubits in this experiment can take only 218 = 262144 numbers, out of which the ordinary classical computer can find the right optimal solution with the lowest energy more easily and accurately than the current error-prone quantum computers )"
p.6-left-2nd-paragraph says "To improve the performance in the presence of noise, we implement an algorithm-specific error detection scheme (= Not error-correction ).. in Fig.4E, we use up to three parity checks and observe consistent improvements in QAOA performance after postselecting on their outcomes. After postselection, the difference of merit factor between experimental results (= 18-ion-qubits with a lot of errors ) and noiseless simulation (= classical errorless simulation ) is reduced by 54% on average"
↑ p.5-Fig.4-(E) shows the original error-prone results (= circles on the light gray line ) was almost the same as the disorderly random guess (= lowest dotted line ) in N = 18 qubits, and after artificial postselection (= discarding all qubits whose errors were detected ), the results (= diamonds ) were slightly closer to the ideal noiseless classical computer's simulator (= top line ).
↑ They artificially chose or postselected only less than 10% of all the results (= discarding more than 90% of qubits due to errors ) after error detection ( this p.18-Fig S17-B ), which illegitimate post-selection method without error correction cannot be used for larger calculations where almost all qubits which showed errors must be discarded.
p.6-left-Discussion says "This provides evidence for the potential (= just speculation, still unrealized ) of QAOA to act as a building block that provides algorithmic speedups on an idealized fault-tolerant quantum computer (= this idealized error-less quantum computer is impossible )."
As a result, even this latest quantum computer with only less than 18 qubits could Not give right answers nor correct errors, which had to rely on ordinary classical computer simulation (= which classical simulation was treated as (pseudo-)quantum speed-up ) for fabricating overhyped news.
The 1-2nd, 5th, 9th, 12th, 14th, last paragraphs of this overhyped news say
"Researchers from Lancaster University and Radboud University Nijmegen have managed to generate propagating spin waves (= false, electron spin is unreal ) at the nanoscale and discovered a novel pathway to modulate and amplify them."
"Their discovery, published in Nature, could (= just speculation ) pave the way for the development of dissipation free quantum information technologies. As the spin waves do not involve electric currents, these chips will (= still unrealized ) be free from associated losses of energy (= wrong, spin wave energy dissipates and disappears in very short time, this-2nd-paragraph, which is why spin wave is still useless )."
"Our discovery will be essential for future spin-wave based computing. Spin waves are an appealing information carrier.. do not suffer from resistive losses (= false, again. Fictional spin wave or magnon quasiparticle (= unstable magnetic fluctuation ) gets easily lost, so can propagate only micrometers with extremely short-lifetime of only picoseconds, which can Not be used for stable information carriers, contrary to hypes )."
"To excite such fast spin dynamics, they used a very short pulse of light, the duration of which is shorter than the period of the spin wave (= applying short-time light wave caused tiny magnetic fluctuation or fictitious spin wave in material )."
"The researchers have now for the first time realized this possibility in practice. They achieved this by exciting the system not with only one, but with two intense laser pulses, separated by a short time delay (= so this research just shone several laser lights on material with No quantum computing )."
"The team explained the observations by considering the coupling of the already excited (imaginary) spin wave with the second light pulse. The result of this coupling is that when the spins are already rotating, the second light pulse gives an additional kick to the spins."
"This mechanism allows for control over the properties of the spin waves such as their amplitude and phase, simply by choosing the appropriate time delay between the excitations (= No mention of practical use nor quantum computing )."
↑ This research just shone several light wave on some material to cause very short-lived magnetic fluctuation with lifetime of only ps, which was measured by seeing the changed polarization of light reflected by the material (= Kerr rotation ).
The electron spin was unobservable. No practical use. The (deadend) quantum computer has nothing to do with this research.
↑ This research paper ↓
p.1-abstract-lower says "using nonlinear magnon–magnon (= fictional quasiparticle for spin wave ) interactions activated by an ultrafast laser pulse. Our experimental findings supported by theoretical analysis show that the mechanism is enabled by the spin canting (← This abstract made No mention of quantum computing, different from the overhyped headline )"
p.2-right-1st-paragraph says "To selectively detect individual spectral components of the wave packet, we tracked time-resolved dynamics of the magneto-optical Kerr effect (MOKE) varying the wavelength of the probe (light) pulse in the visible spectral range (= fictitious spin itself is unobservable. All they could measure was the change of polarization of light reflected from magnetic material called Kerr effect )."
p.3-Fig.2-a shows this fictitious spin wave (= magnon quasiparticle) or magnetic fluctuation observed as probe light's polarization change (= Kerr rotation ) lasted for only less then 100 ps. ← Spin wave was too short-lived (= spin wave's lifetime < 100 ps ) to use as data transfer or storage.
p.12 shows this experiment was conducted at extremely low temperature (= T = 29K ), which is impractical.
p.18-used artificially-chosen parameters for (fictional) spin wave. No quantum mechanical prediction, so No evidence of spin.
As a result, quantum mechanical fictional electron spin forced physicists to do only useless researches intended only for publishing papers in journals that need the deadend quantum computer as a fake scientific target.
The 1-2nd, 4-5th, 7th, 9th, last paragraphs of this overhyped news say
"A team of Chinese scientists has achieved a breakthrough in quantum simulation (= there is No such thing as quantum simulation ), building the world's largest ion trap system with single-qubit resolution. The milestone achievement marks a significant leap towards (= still unrealized ) large-scale quantum computing."
"This work is the largest quantum simulation or computation performed to date in a trapped ion system (= false, this research's so-called "(pseudo-)quantum simulator" is Not a quantum computer )."
"This innovation has the potential (= just speculation ) to be applied to realms like materials and pharmaceutical development, engineering, and artificial intelligence (= this research's just unstably trapped 300~500 ions with high error rates, and No quantum computation was made, so it has nothing to do with pharmaceutical, AI or anything )"
"Like bits in classical computers, qubits are the building blocks of quantum computers. However, controlling and manipulating qubits consistently is a major challenge due to their delicate quantum nature"
"Ion traps, a leading platform for quantum information processing, have achieved simulations with tens of ions by confining them with electromagnetic fields. This makes them highly promising for future large-scale applications. However, a major challenge remains of balancing stable trapping of a large number of ions with the precise control needed for individual manipulation."
"Using cryogenic monolithic ion trap technology and a two-dimensional scheme, researchers from Tsinghua University realized a stable trapping of 512 ions for the first time (= just trapping 512 ions by external electromagnetic field with No quantum computation )"
"Additionally, the team has also successfully conducted quantum state measurements (= vague "quantum" something ) with "single-qubit resolution" across an unprecedented 300 ions, according to the study (= No mention of quantum computation nor practical use )"
↑ This research just trapped 300 ions in external electromagnetic field for a short time, and illuminated them with the global laser light without quantum computation nor manipulating individual ions.
These useless trapped ions could Not simulate anything.
And they did Not disclose the final error rate of these 300-ion-simulation results, because of their extremely high error rate.

p.2-Fig.1b says "Relevant energy levels of the 171Yb+ ion. The qubit is encoded in the S1/2 hyperfine levels |0⟩ ≡ |F = 0, mF = 0⟩ and |1⟩ ≡ |F = 1, mF = 0⟩, and can be rotated by a resonant global microwave ( each ion's two energy levels related to the nuclear magnetic moment's direction are used as a qubit's 0 or 1 state. This research shone a global light on all the 300 ions to vaguely change their energy levels instead of precise manipulation of individual ions for quantum computing )."
p.2-Fig.1-f says "The experimental sequence to quasi-adiabatically prepare the ground state of an Ising model Hamiltonian (= adiabatically finding the lowest-energy ground state in annealing or optimization problem was already done by D-Wave's 2000 qubits that are larger than this research's only 300 ion qubits, and this adiabatic simulation is irrelevant to quantum computers )
".. Then we turn on the Ising model Hamiltonian H0 via the global 411 nm laser (= Not manipulating individual ions by different laser lights, so this 300-ion adiabatic quantum simulator was inferior to D-Wave annealing machine. Quantum research is regressing )"
p.4-Fig.2-a shows the average correlation between different ion pairs, which deviated from the ideal C = 1 (= darkest red ), as shown in Fig.2b = a single shot includes errors of blue ions (= wrong energy state ).
Other patterns are 300 ions' energy states when different light frequencies (= detuned ) were used.
p.6-right-2nd-paragaph says ". Furthermore, in the future (= still unrealized ) by integrating the 2D laser addressing into the system, our 2D ion crystal may (= just speculation ) also support high fidelity two-qubit entangling gates (= which means this research did Not perform two-qubit gate operation, so Not a quantum computer ) mediated by the transverse phonon modes"
p.16-C Error analysis-1st-paragraph says "In particular, when coupled dominantly to the COM mode, the ideal final state should be a GHZ state (= all qubits are 0 or 1 states ) for N = 300 qubits. However, in practice various error sources can degrade the fidelity for this macroscopic entangled state. Therefore we do not expect to observe this multipartite entanglement in the current experiment, and leave it as future (= still unrealized ) research directions."
↑ So this experiment could Not even give the final error rate of the final simulated answers due to their extremely error-prone 300 ion qubits."
As a result, this experiment just trapping 300 impractical ions in external electromagnetic field with a lot of errors was completely useless for any (hyped) technologies such as quantum computer, drug discovery and AI.

"There's a hot new BEC in town that has nothing to do with bacon, egg, and cheese.

"Writing in Nature,.. supported by theoretical collaborator at Radboud University in the Netherlands, has successfully created a unique quantum state of matter called a Bose-Einstein Condensate (BEC) out of molecules."
"Their BEC, cooled to just five nanoKelvin, or about -459.66°F, and stable for a strikingly long two seconds (= unstable, easily broken, useless ), is made from sodium-cesium molecules. Like water molecules, these molecules are polar, meaning they carry both a positive and a negative charge. The imbalanced distribution of electric charge facilitates the long-range interactions "

↑ This research just cooled molecules to almost absolute zero, and made them condense for only a short time (= several seconds ).
No practical use. No quantum mechanical prediction.
In Bose Einstein condensate (= BEC ), only at extremely cold temperature (= almost absolute zero, so impractical), atoms or molecules are said to condense temporarily by weak (electric) attraction and interfering de Broglie wave ( this p.15 ), which do Not need quantum mechanics.
↑ This BEC state existing only at almost absolute zero is easily broken even by a small stimulus or energy, so using this very fragile BEC for simulating or computing something is impossible.
Deadend quantum computer is often used as a fake scientific target for this kind of impractical quantum mechanical research that is going nowhere.

"Quantinuum's latest benchmark,.. tried a different system, called the H2-1, which features 56 trapped ion qubits" ← Each qubit can take only 0 or 1 bit states, so just 56 qubits or 56 bitstring are far from achieving quantum supremacy that will need more than millions of qubits ( this 6th-paragraph ).

By contrast, Quantinuum says its 56 qubit H2-1 system managed to achieve an XEB score of roughly 0.35 (= even this latest Quantinuum 56 ion qubits' error rate was 65%, too bad to claim quantum supremacy or calculate anything )."
"the biz isn't claiming quantum supremacy and,... it admits there's a lot of work left to do." ← They admit No quantum supremacy
"The H2 quantum computer produces results without making even a single error about 35 percent of the time" ← it means error rate was too bad = 65%, which is completely useless.
"That might not sound that reliable"
↑ This Quantinuum 56-qubit research paper ↓
p.1-right-2nd-paragraph, p.2-left-2nd-paragraph mention random circuit sampling (= RCS ), which is just manipulating qubits randomly to output random meaningless numbers ( this p.3(p.2)-left-1st-paragraph ).
p.2-left-last-paragraph says this Quantinuum H2-quantum computer used each Yb+ ion's two energy (hyperfine) states as bit's 0 and 1 states.
p.4-left-3rd-paragaph says FXEB is an estimator of the fidelity F.
p.13-Fig.9-(a)(b) shows just 12 random qubit operations (= depth d = 12 ) on these 56-ion qubits caused error rate of 65% (= fidelity is 35% or 0.35 ).
p.13-right-2nd-paragraph says "We emphasize that none of these results is conclusive regarding how the difficulty of RCS (= random circuit sampling ) grows... Easiness results suggest that at sufficiently large noise rates, RCS may be classically feasible.." ← quantum supremacy is still unclear ( or fake ).
↑ As long as today's (fake) quantum computers are too error-prone to give right answers, Quantum supremacy or advantage (= based on outputting random meaningless numbers ) is fake.
The 1-5th, 9th, 17th paragraphs of this hyped news say
"Quantum computers have the potential (= speculation ) to solve complex problems in human health, drug discovery, and artificial intelligence millions of times faster than some of the world's fastest supercomputers (= overhype )... But before that can happen, the computer industry will need a reliable way to string together billions of qubits—or quantum bits—with atomic precision ( = the present pseudo-quantum computers have far less qubits than a billion )."
"Connecting qubits, however, has been challenging for the research community. Some methods form qubits by placing an entire silicon wafer in a rapid annealing oven at very high temperatures."
"With these methods, qubits randomly form from defects (also known as color centers or quantum emitters) in silicon's crystal lattice. And without knowing exactly where qubits are located in a material, a quantum computer of connected qubits will be difficult to realize."
"But now, getting qubits to connect may (= just speculation ) soon be possible. A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) says that they are the first to use a femtosecond laser to create and "annihilate" qubits on demand, and with precision, by doping silicon with hydrogen (= hype, this research just created almost randomly and disorderly defects in silicon, this p.12-Fig.12-a,b,c, and still they were Not used as qubits )."
"The advance could (= just speculation ) enable quantum computers that use programmable optical qubits or "spin-photon qubits" to connect quantum nodes across a remote network. It could also advance a quantum internet that is not only more secure but could also transmit more data than current optical-fiber information technologies (= false, the impractical quantum internet with massive loss of fragile photons cannot send much data )."
"The new method uses a gas environment to form programmable defects called "color centers" in silicon. These color centers are candidates for special telecommunications qubits or "spin photon qubits." The method also uses an ultrafast femtosecond laser to anneal silicon with pinpoint precision where those qubits should precisely form (= None of this hyped concepts were achieved in this research )"
"Now that we can reliably make color centers, we want to get different qubits to talk to each other—which is an embodiment of quantum entanglement—and see which ones perform the best. This is just the beginning (= still unrealized )"
↑ This research just measured light interacting with carbon-atomic-center defects created in random locations in silicon.

Another recent research by Harvard university about (fictional) quantum supremacy was just pie-in-the-sky theory with No experimental verification, as this hyped news (= 2nd-last-paragraph ) says
"The researchers wish to explore the relationship between pseudomagic states and concepts in quantum information theory in the future. Additionally, they want (= still unrealized ) to explore the experimental realization of pseudomagic states (= magic state is just an imaginary quantum superposition or parallel world state of a qubit ) with existing and near-term quantum devices."

"Researchers at QuTech have found a way to make Majorana particles (= fictional quasiparticle ) in a two-dimensional plane. This was achieved by creating devices that exploit the combined material properties of superconductors and semiconductors"
"Majorana qubits are based on states of matter that are topologically protected (= No evidence of "protected" ). This means that small local disturbances cannot destroy the state of the qubit. This robustness to external influences makes Majorana qubits highly desirable for quantum computing (= hype and false, even single Majorana quasiparticle qubit has Not been realized, so No evidence of robustness )"
"Previously, researchers at QuTech—a collaboration between the TU Delft and TNO—have used a one-dimensional nanowire to demonstrate a new approach to studying Majoranas by creating a Kitaev chain (= lack reality ). In this approach, a chain of semiconductor quantum dots are connected via superconductors to produce Majoranas (= false, fictional Majorana quasiparticle itself can Not be found )"
"In the longer term, the flexibility and scalability of the 2D platform should (= just speculation, still useless ) allow us to think about concrete strategies to create networks of Majoranas and integrate them with auxiliary elements needed for control and readout of a Majorana qubit"

p.6-conclusion made No mention of qubit nor quantum computer (= even single Majorana qubit could Not be realized ).
p.11-last-paragraph~p.12-1st-paragraph just artificially chose parameters of unphysical Majorana quasiparticle model to fit experimental results with No quantum mechanical prediction.
↑ As a result, this research just measured some electric conductance, and did Not build even one qubit, much less quantum computers. No practical use.
This research about fictional Majorana quasiparticle is a typical example which is useless except for publishing papers in journals.

"The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor material—that could be used to send and store quantum information over widely used telecommunications wavelengths (= there is No such thing as quantum internet, which is just hyped pseudo-science )"
"It's still a Wild West out there, said Professor of Applied Physics and of Electrical Engineering at the Harvard."
"Now, Hu and a team of researchers have developed a platform to probe, interact with and control these potentially (= still unrealized ) powerful quantum systems (= vague quantum something ). The device uses a simple electric diode, one of the most common components in semiconductor chips, to manipulate qubits (= this research has Not built a qubit at all ) inside a commercial silicon wafer."
"Using this device, the researchers were able to explore how the defect responds to changes in the electric field, tune its wavelength within the telecommunications band and even turn it on and off (= hype, this research could Not control the light wavelength )."
"Quantum defects, also known as color centers or quantum emitters, are imperfections in otherwise perfect crystal lattices that can trap single electrons. When those electrons are hit with a laser, they emit photons in specific wavelengths"
"The defects in silicon that researchers are most interested in for quantum communications are known as G-centers and T-centers. When these defects trap electrons, the electrons emit photons in a wavelength called the O-band, which is widely used in telecommunications."
"the team found that when a negative voltage was applied across the device, the defects turned off and went dark (= which means the applied voltage weakened interaction between light and silicon )"
"We can use that information to inform how to build the best environments for these defects in future devices (= No mention of practical use, and No qubits nor quantum internet was built in this research )."
↑ This research just measured how the intensity of light with some wavelength changed by applied voltage, and did Not build a quantum computer's bit (= qubit ) nor quantum internet.

p.2-Fig.1 says "Carbon-related silicon color centers are integrated into lateral p+ -p-n+ junctions (diodes) fabricated in silicon.. The color centers are optically excited by a 532 nm laser and fluoresce at 1278 nm in the telecommunication O-Band."
p.2-right-1st-paragraph says ". Above a spatially dependent threshold voltage, the ensemble zero phonon line (ZPL) wavelength (= light wavelength not affected by thermal phonons ) experiences a redshift up to 100 GHz at a rate of approximately 1.24 ± 0.08 GHz/V. Additionally, we observed the continuous reduction of the G center optical fluorescence with increasing reversed bias voltage, and at -210V the fluorescence was fully suppressed"
↑ This research just measured the intensity of light with wavelength 1278nm interacting with the silicon defect decreasing (+ its wavelength was slightly redshifted ) by the applied voltage (= p.4-Fig.3a, b shows the light intensity became almost zero in the applied voltage of -200 V ).
Furthermore, this light intensity drastically decreased in the temperature of just 80K ( this p.7-Figure 7 shows the darker blue light of 80 K decreased its intensity ).
So this silicon defect interacting with light that must be operated at extremely low temperature (< 50K ) is impractical, and this research has nothing to do with qubits or quantum networks, contrary to this hyped headline.
This p.4-1st-paragraph of reviewers says
"1. Although the wavelength tuning is demonstrated, the intensity simultaneously decreases. This fact
means that the formation of the depletion layer under voltage application makes the G centers
unstable. Therefore, this technique is hard to directly use for the control of the G centers for
quantum applications"
↑ The decreased light (= messenger ) by voltage in this research can Not be used for any quantum application such as (imaginary) quantum network.

"A team ..from the Institute of Solid State Physics at Graz University of Technology (TU Graz) has now significantly improved these simulations using machine learning, which greatly accelerates the development and application of novel MOF (= metal-organic framework )"
"The simulated supercells often contain tens of thousands or even hundreds of thousands of atoms. For these huge systems, it is then necessary to solve the equations of motion five to 10 million times. This is far beyond present day computational possibilities using reliable quantum mechanical methods (= quantum mechanics has been unable to explain metals and semiconductors )"
"Thus, until now, transferrable force fields (= pseudo-potential for impractically-time-consuming molecular dynamics ) often parametrized on the basis of experiments (= Not quantum mechanical prediction ) were often used for such calculations. However, the results obtained with such force fields turned out to be generally not sufficiently reliable"
"This is now fundamentally changed by the use of machine-learned potentials... For the necessary material-specific machine learning of the potentials (= unreal pseudo-potentials ), the quantum mechanical simulations need to be carried out only for comparatively few and significantly smaller structures (= because useless quantum mechanical calculations took much more time )."
"In addition to simulating thermal conductivity, the new machine-learned potentials are also ideal for calculating other dynamic and structural properties of MOFs. These include crystallographic structures, elastic constants, as well as vibrational spectra and phonons (= simulating fictional phonon quasiparticles is meaningless ),"

"The experimental investigation of promethium included developing a novel, water-soluble complexing agent and using X-ray absorption spectroscopy to determine the electronic structure of the element.

By varying the strength of both voltages and the frequency of the oscillating voltage, they were able to observe characteristic resonances in the tunnel current (= this research measured just electric current, Not spin ). The exact shape of these resonances allowed them to draw conclusions about the processes that occurred between the tunneling electrons and those of the molecule (← ? )."
"That process is the so-called spin transfer torque, for which the pentacene molecule is an ideal model system,..

↑ This research just artificially chose fitting parameters of unphysical spin model lacking real atomic picture without quantum mechanical prediction.
So there is No evidence of spin.
The 1st, 3rd, 5th, 8th, 12th, 14th paragraphs of this hyped news say
"In a study published in Nature Communications, a team of scientists led by Rice University predicts the existence of flat electronic bands at the Fermi level, a finding that could (= just speculation ) enable new forms of quantum computing and electronic devices (= actually, this research has nothing to do with (hyped) quantum computing or new electronic devices )."
"Electrons, being charged, repel each other and move in correlated ways. Si's team found that electron interactions can create new flat bands (= flat band means the unrealistic infinite effective mass of a pseudo-electron ) at the Fermi level, enhancing their importance."
"Typically, a particle's energy changes with its momentum. But in quantum mechanics, electrons can exhibit quantum interference, where their energy remains flat even when their momentum changes. These are known as flat bands (= due to the unrealistic infinite effective mass, this 2nd-paragraph )"
"The team's findings suggest new ways to design these, which could (= just speculation ) inspire new applications for these materials in quantum bits, qubits and spintronics (= overhype, this research is completely irrelevant to the deadend quantum computer's qubits and spintronics ). "
"The team's research reveals that this includes anyons and Weyl fermions, or massless quasiparticles (= fictional quasiparticle model ) and fermions that carry an electric charge. The researchers found that anyons are promising agents for qubits (= lie, the unreal fractional-charge anyon quasiparticle cannot make qubits ), and materials that host Weyl fermions may (= just speculation ) find applications in spin-based electronics (= false, too )."
"Our work provides the theoretical foundation for utilizing flat bands in strongly interacting settings (= this research is just about the imaginary theory with No experimental realization )"
↑ This research just provided a useless theory of imaginary flat bands with unreal infinite effective mass and quasiparticle models with No experiment, No quantum mechanical prediction nor application.

p.1-abstract made No mention of quantum computing nor detailed application (= this research is irrelevant to any practical use ).
p.3-left-(1) shows the abstract unphysical Hubbard model with artificially-adjustable interaction parameters and No real particle picture.
p.3-right-2nd-paragraph says "Varying the interaction (= just varying free interaction parameters ) strongly influences the spectral weight of the emergent flat band (= infinite effective mass )"
p.3-right-3rd-paragraph says "so that the quasiparticle (= fictional particle ) weight of the c-electrons remains to be 1"
p.5-right~p.6 shows unphysical (meaningless) quantum mechanical model or equation where each electron and fictional quasiparticle was denoted as nonphysical math operators with No concrete shapes.
This p.5 shows freely-chosen parameters with No quantum mechanical prediction nor calculation.
This p.2-1. of reviewer says "since the appearance of the flat band at the Fermi level would be highly model-dependent, one cannot say that the results in the manuscript can be generally applied to other systems (= this research is based on artificially-created model instead of quantum mechanical theory )"
↑ This research is also a typical example intended only for publishing papers in journals whose impractical pseudo-science (= obstructing science development in all industries ) allows the old-fashioned archaic universities to skyrocket tuition limitlessly.
The 1st, 4th, 7th, 13-14th paragraphs of this hyped news say
"A team of experimental physicists led by the University of Cologne have shown that it is possible to create superconducting effects in special materials known for their unique edge-only electrical properties (= vague properties ). This discovery provides a new way to explore advanced quantum states that could (= just speculation ) be crucial for developing stable and efficient quantum computers (= false, this research has nothing to do with (deadend) quantum computers )."
"Theory predicts that a combination of superconductivity and the quantum anomalous Hall effect (= just based on classical Lorentz magnetic force ) will give rise to topologically protected particles called Majorana fermions (= fictional quasiparticle ) that will potentially (= just speculation ) revolutionize future technologies such as quantum computers."
"When we inject an electron into one terminal of the insulator material, it reflects at another terminal, not as an electron but as a hole, which is essentially a phantom of an electron with opposite charge."
"This discovery opens up numerous avenues for future research. Next steps include experiments to directly confirm the emergence of chiral Majorana fermions (= which means this fictional Majorana fermion quasiparticle has Not been found yet )"
"Understanding and harnessing topological superconductivity and chiral Majorana edge states could (= just speculation ) revolutionize quantum computing by providing stable qubits that are less susceptible to decoherence and loss of information (= overhype, this imaginary topological quantum computer, which has Not realized even one qubit, has No evidence of stable qubits )."
Quantum mechanics tries to rely on fictional quasiparticles to explain observed physical phenomena such as electric conductance, which is why the current science stops progressing.
The 6th, 10th paragraphs of this site say
" the only Majorana fermions for which scientists have evidence are in the form of a “quasiparticle (= Not actual particle )"
"In certain magnetic materials, the electrical conductivity of a thin layer of material changes in steps as a small magnetic field is varied, increasing and decreasing in jumps of a certain size. The signature of the Majorana fermions is a conductivity jump of half the normal size."
↑ So physicists unreasonably try to (mis)interpret some electric conductance as a sign of illusory Majorana quasiparticle with fractional charge ( this 6th-paragraph ), which can be normally explained by a real electron with an integer charge, though.
This 1st-paragraph says
" The Andreev reflection occurs at an interface of a fractional quantum Hall state of a two-dimensional electron system in a strong magnetic field at low temperatures. In this phenomenon, the incidence of fractionally charged quasiparticles on an interface transmits an electron and reflects a hole having a fractional charge... (= just fiction )"

p.1-abstract made No mention of "quantum computer", so this research has nothing to do with quantum computer, contrary to the hyped news.
p.2-Fig.1 just measured electric resistance (= R = 1/conductance ) under various magnetic field H and current I at extremely low temperature 25mk, which is impractical.
p.3-Fig.2, p.4-Fig.3 also just measured electric resistance R, with No quantum computers nor qubits.
↑ This research with No practical application is useless except for publishing papers in journals, which need fictional scientific target "(deadend) quantum computer".
The latest research on IBM quantum computer by Caltech used only up to 24 ~ 32 (superconducting) qubits or only 32 bitstring to simulate some impractical physical model, and their 24-qubit quantum computer is still too error-prone and showed No quantum advantage, contrary to hypes.
↑ This Peer Review File ↓
p.2-1st-paragraph says "In this way, higher-order (unphysical) topological states can be simulated on IBM quantum computers. In principle, I cannot agree with the authors that this method can realize quantum advantage with exponentially large Hilbert space (= No quantum advantage )."
p.2-3rd-paragraph says "For NISQ, it is actually difficult to simulate successfully some quantum phenomena mainly due to serious errors and limited number of qubits"
p.3-2nd-paragraph says "However, for a single-particle problem, the dimension L^d is accessible in classical computer. The quantum advantages are Not obvious in dealing with single particle higher-order topological problem (= No quantum advantage )"

p.1-right-last-paragraph~p.2-left-top says "classical numerical
methods—e.g., exact diagonalization (ED)...
Although the scalable realization of larger lattice systems requires
hardware exceeding present capabilities, our approach presents a possible avenue toward (= still unrealized ) useful quantum advantage as quantum simulator platforms continue to rapidly improve."
p.3-left-2nd-paragraph mentions (unphysical) SSH model where qubits are connected and changed by some tunable coupling strength parameters.
p.3-right-2nd-last-paragraph says " Moreover, to improve data quality amidst hardware noise, we employ a suite of error mitigation (= QEM ) techniques (= error correction by classical computers, this p.1-right-1st-paragraph ),.." ← Classical computers were needed to correct their error-prone (useless) IBM quantum computers !
".. in particular, readout error mitigation (RO) that approximately corrects bit-flip errors during measurement, a post-selection (PS) technique that discards results in unphysical Fock-space sectors (= artificial post-selection of desirable qubits without quantum error correction, so No quantum advantage )"
p.4-Fig.2-d shows qubit operations and says "The quantum circuits are executed on the quantum processor, and results are post-processed with RO and PS error mitigations to reduce effects of hardware noise", which must be done by classical computers, this-lower-Quantum error mitigation. So IBM quantum computers alone could give only erroneous answers with No advantage"
p.5-Fig.3-d shows occupancy fidelity (= 1 - error rate ) decreased to almost zero (= which means their quantum computer error rate increased to almost 100% ) with time even after ad-hoc post-selection, so this IBM quantum computer with only 20~32 qubits are completely useless, too error-prone, No advantage.
p.6-Fig.4 used only 18 qubits and the (occupancy) fidelity decreased to almost zero (= error rate increased to 100% ) with time, which cannot give right answers.
p.9-right-1st-paragraph says "Nonetheless, for the quantum simulation of sophisticated topological lattices as described to be achieved in their full potential, fault-tolerant quantum computation, at the least quantum devices with vastly improved error characteristics and decoherence times, will likely be needed (= still quantum advantage was unrealized )"
↑ All the current quantum computers including IBM are unable to give right answers due to their a lot of errors, so IBM tried to fix errors by the ad-hoc error mitigation based on post-process by classical computers.
But even the IBM 127-qubit eagle quantum computer (based on this ad-hoc error mitigation) was outperformed by ordinary classical computer, with No quantum advantage.
This latest research used only 32-qubit IBM quantum computer, which shows all other larger IBM quantum computers with 127~1000 qubits ~ were more error-prone and useless (= this is why they used only 32 qubits, though IBM already had 127~1000 qubit quantum computers ).
This p.8-right-2nd-paragraph says "For this discussion, we largely leave aside tensor network methods, as their advantage over ED is unclear in the generic setting of lattice dimensionality"
↑ This research just (baselessly) speculated that quantum computer with larger sizes or more qubits may outperform the classical ED method (= still, No quantum advantage by larger numbers of qubits was realized in this research ).
But this ED (= exact diagonalization ) is the slow classical method, and they did Not compare their quantum computer with much faster classical tensor network method ( this p.5 ).
As a result, it is impossible for the current error-prone quantum computers with only less than 50 qubits to achieve (or speculate ) quantum advantage that is said to need millions of qubits with much less errors ( this 4th-paragraph ).
The 1st, 3rd, 7th, last paragraphs of this hyped news say
"In a significant leap forward for quantum technology, researchers have achieved a milestone in harnessing the frequency dimension within integrated photonics. This breakthrough not only promises (= just speculation ) advancements in quantum computing (= hype, quantum computer is already deadend ), but also lays the groundwork (= still unrealized ) for ultra-secure communications networks (= this is also hype )."
"In a study published in Advanced Photonics, researchers from the Centre for Nanosciences and Nanotechnology (C2N), Télécom Paris, and STMicroelectronics (STM) have overcome previous limitations by developing silicon ring resonators with a footprint smaller than 0.05 mm2 capable of generating over 70 distinct (laser light) frequency channels spaced 21 GHz apart."
"To validate their approach, the team performed experiments at C2N, showing quantum state tomography on 17 pairs of maximally entangled qubits across different ( light ) frequency bins. This detailed characterization confirmed the fidelity and coherence of their quantum states, marking a significant step towards practical quantum computing (= false, this research is far from realizing quantum computing )."
"Telecom Paris, and STM researchers serves as a beacon, guiding the way towards a future (= uncertain future, still unrealized ) where quantum networks offer secure communication (= just imagination )."
↑ This research paper ( this ↓ ).
p.2-right-2 Results say "The spiral waveguide length is set to 3.54 mm (= this research was conducted in a laboratory without using long-distance network line, so useless ) to yield a free spectral range (FSR) near 21 GHz (= laser light frequency )"
p.3-right-2nd-paragraph says "The ring resonator intrinsically produces frequency-bin entangled qudits (= different frequencies f of weak laser lights express 0 or 1 bit states )"
p.3-right-3rd-paragraph says "filter out 70 dB of the laser light (= whose light frequency was used as quantum information ), and an additional filtering of the laser light is done"
p.4-Fig.4-(d) shows generated number of pairs of weak light wave (= or photon ) is about MHz = 106 light pairs per second, which was drastically decreased to only 800 Hz or only 800 pairs of lights detected (= Fig.4-c = two photon coincidence counts or number of pairs of lights where two light or phorons were detected simultaneously ).
↑ Almost all the fragile quantum information photons or very weak light was lost when detected (= initial light pairs decreased to about 1/1000, = 106 → 800, which massive photon loss shows sending fragile quantum information is impractical forever ).
p.7-Fig.8-(a) shows Quantum bit error rate (= QBER, p.6-right-4th-paragraph ) expressed as black dots were 10~20% (= error rates were different in different light frequencies or FSR unit ), which means about 10~20% of the received light showed bit information errors, which must be corrected by ordinary classical communication, so quantum information is meaningless, useless.
p.7-Fig.8-(b) shows sifted (= remaining ) key rate is only 0~2 bits/s (= only 0 ~ 2 weak light pairs were detected per second ), which is too few and too slow to be practical communication due to massive light or photon (= quantum information ) loss (= initnial 106 light pairs decreased to only 0~2 photon pairs ).
This research showed significant loss of light or photons, even when light was sent over very short distance within a laboratory.
So sending quantum information or key over practically-long distance is impossible forever.The 1st, 7th, 17th paragraphs of this overhyped news say
"Quantum computers have to be kept cold to function—very cold. These machines generally run at "just a few degrees above absolute zero (= which is impractical ) says assistant professor of mechanical and industrial engineering at Northeastern University."
"By firing lasers at very thin metals, researchers can induce controlled oscillations like acoustic waves in drums."
"So this isn't the ultimate solution in room temperature quantum computing (← ? ), but it is one major step toward that goal"

p.2-abstract-last says "Our results could enable THz phononic (= unreal quasiparticle ) metamaterials based on van der Waals heterostructures for ultrabroadband acoustic filters and modulators, as well as novel routes for thermal engineering" ← No mention of quantum computer, which has nothing to do with this research, contrary to hypes.
p.4-2nd-paragraph says "We use van der Waals heterostructures composed of FLG (= few-layer graphene ), hBN (= hexagonal boron nitride ), and WSe2 for coherent
generation, detection, and manipulation of THz acoustic phonons (= fictional quasiparticle representing material's vibration )...
We chose FLG for THz phonon transduction
upon femtosecond laser excitation"
p.4-last-paragraph says "When the coherent phonon pulse (= just vibration or sound wave ) reaches the WSe2 layer, the WSe2-hBN distance oscillates by the nanomechanical phonon motion. This motion modulates the effective dielectric constant around the WSe2 layer, resulting in a shift of the WSe2 exciton (= fictional quasiparticle for excited electron ) energy. The phonon expansion and compression lead to an oscillation of the exciton peak in WSe2"
p.5-1st-paragraph says "This effective coupling between acoustic phonons and excitons allows us to detect phonon oscillations by monitoring the exciton peak energy using a resonant optical probe pulse (= vibration or fictional phonon excited by pump light was detected by probe light, so No quasiparticles such as phonon and exciton were directly detected )"
p.5-2nd-paragraph says "The pump-induced transient reflectance change ( = vibration or fictional phonon quasiparticle was detected as probe light reflectance R change )"
p.10-lower-1D mass-spring model~p.11 tried to express material's vibration using classical spring model with artificially-chosen parameters with No quantum mechanical calculation nor prediction.
↑ No quantum computing was involved in this research.
p.16-Fig.1 shows "A pump light pulse induces an ultrafast expansion of few-layer graphene (FLG), launching an acoustic-phonon pulse (= vibration ) that propagates across the hBN spacer. The phonon pulse interacts with an unknown layer and is then detected by a monolayer WSe2. A broadband probe pulse with a time delay monitors the exciton peak shift induced by the phonon pulse, which was detected as probe light reflectance R change.
All other Fig.2~4 did the same thing; material's vibration or fictional phonon excited by pump light was detected as reflectance change (= ΔR/R ) of the probe light.
↑ This research has No practical use, and No relation to (hyped) quantum computers, which is useless except for publishing papers in journals.
There was a shocking news of Trump assassination attempt and a few victims.
Some weird things seemed to happen.
Why did the professional secret service and law enforcement allow the shooter to fire a rifle from such a vantage point 'suitable' for it, which will be a great concern for Trump safety for the time being.
Counter snipers were assigned not only to 'sitting' presidents but also to 'former' presidents ? Or is this happening just in (quantum mechanical) parallel worlds ? Is it related to this attempted assassination ?
The 2nd, 7th, 11-12th, 14-16th paragraphs of this overhyped news say
"Oxford Ionics has said its chip can be mass-produced and means the world's first useful quantum computer could be built in three years time (= Overhype. The useful quantum computer is definitely impossible in this latest research )"
"The company said the results indicate that "the dawn (= meaning still useless ) of useful quantum computing is far closer than previously thought"
"The computers found in most of our homes and workplaces process data in bits, which have a binary value of either zero or one."
"Quantum computers instead use a two-state unit for data processing called a qubit"
"There have already been functioning quantum computers for a number of years, but they are generally much too small and their results are much too noisy (= too error-prone ) for real-world applications (= so still useless )"
"We still don't understand very well the full potential of large-scale quantum computers."
"There are still lots of practical challenges that come from scaling a little device up to something you could use to solve real problems, but this looks very promising (= just baseless speculation )"
↑ This kind of hyped news tends to hide the crucial information of how many qubits (= each qubit takes only 0 or 1 bit state ) were used in this alleged 'promising' quantum computer.
The 4th-paragraph of another overhyped news misleadingly says
"It said it would (= just speculation ) now build a scalable 256-qubit chip that can be manufactured on existing semiconductor production lines. Qubits, or quantum bits,"
↑ This 256-qubit quantum computer is false, and fake news.
According to Oxford ionics, their latest ion quantum computer has only 10 qubits (= each qubit can take only 0 or 1 state, so just 10 bitstring ), which is still Not a computer, much less useful.
↑ This research paper (= still unpublished ) on their latest ion-qubit quantum computer ↓
p.1-abstract mentions "To verify our approach, we experimentally demonstrate low-noise site-selective single- and two-qubit gates in a seven-zone ion trap that can control up to 10 qubits (= far from millions of qubits required for useful quantum computer, this summary )"
"... We also electronically generate two-qubit maximally entangled states with 99.97% fidelity" ← It means their error rate of each two-qubit operation is still high 0.03% (= 3 × 10-4 ), which error rate is much higher than ordinary classical computer, and far worse than 10-15 required for practical quantum computer ( this p.1-abstract ).
p.3-left-III says "in a seven-zone single-layer linear microfabricated trap cooled to ≈ 5 K (= impractically-low temperature ). Each zone contains 6 − 10 independent electrodes over 350 µm (= a very big, bulky impractical zone containing only 1~2 ion qubits, Fig.2,3 )"
"The qubit states |↑⟩ and |↓⟩ are encoded in the 4S1/2 Zeeman sublevels of 40Ca+ ions (= each ion's two energy levels were used as each bit state 0 or 1 ) trapped 40 µm above the chip surface"
p.5-Fig.3 shows each bulky zone contains only two qubits interacting with each other. ← The total was 10 ion qubits, but these 10 ion qubits were separated with No connection. Only two ion qubits were connected inside each one zone.
↑ So this is just a two-qubit (= 01 ) device (= less then 10 qubits or far less than millions of qubits required for useful quantum computer ), which is Not even a computer at all.
The overhyped "3-Year Quantum ‘Mass Production (= only 2 error-prone useless qubits now → millions of errorless qubits in 3 years !? )" is definitely impossible.
Their 2-qubit error rate was still high, impractical, and there's a catch: They did Not connect all ten qubits nor calculate any meaningful values.
So quantum computers are already deadend, hopeless, as shown in the latest Quantinuum's 56 ion qubit's fake supremacy outputting random meaningless numbers with 65% error rates (= this is just estimation, the real error rate after the long qubit operation was much worse ). Just hypes remain.
Academia, universities benefit from these hopeless science which is useless except for publishing papers in journals by preventing all industries from developing really useful technology or curing diseases.
Another latest (deadend) quantum computer research ↓
p.1-abstract says "microwave signals are delivered to each qubit from room-temperature electronics to the cryogenic environment through coaxial cables. Limited by the heat load of cabling and the massive cost of electronics, such an architecture is Not viable for millions of qubits required for fault-tolerant quantum computing (= which is impossible to achieve )"
p.4-right-2nd-paragraph says "We extract single-shot readout fidelities of 97.29 ± 0.13% (= single-qubit error rate is about 3%, extremely bad, far from useful quantum computer )"
p.7-right-last mentions (only) one single qubit was used in this research (= one superconducting qubit consisting of classical circuit, this p.8 ). ← far from millions of qubits needed for practical quantum computer
↑ This research was meaningless with No improvement, as this p.2-Major issue says
"The major issue is, in my view, what is the advantage of this work ? ... however, the heat load on other RF
components is still a problem. Therefore, I do not think the proposed pulse generator is a game
changer."
"Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated an innovative approach to find breakthrough materials for quantum applications (= hype, No breakthrough )."
"Quantum information science involves the use of atomic-scale phenomena to encode, process, and transmit information. One way to achieve this control is to create defects in materials—such as replacing one type of atom with another. "
"For defects to work for quantum applications, they need to have very specific electronic properties and structures,.. They should preferably be able to absorb and emit light with wavelengths in the visible or telecommunications range."
"There's a catch, however. Defects with good quantum properties are very difficult to find"
"The massive number of calculations, based on quantum mechanics principles,... The analysis identified one defect—made by substituting a sulfur atom with a cobalt atom"
"Here's how it worked: A 2D WS2 sample in a super-low-temperature vacuum was heated, and its surface was blasted with argon ions at just the right angle and energy. This caused a small fraction of the sulfur atoms to pop out, leaving tiny holes in the material"
"A mist of cobalt atoms was applied on the surface. The sharp metal tip of a scanning tunneling microscope was used to find a hole and nudge a cobalt atom into it—similar to putting in golf. "
"Importantly, this method enables fabrication of identical defects. This is necessary for defects to interact with each other in quantum applications—a phenomenon known as entanglement (= hype, entanglement is a meaningless useless concept ). In quantum communications, for instance, one possible application is for defects to transmit information across a long-distance fiber-optic cable through light emission and absorption (= hype, again, this research has nothing to do with quantum communication )."
"The team's next step is to make additional measurements on the cobalt defect's properties and investigate how to improve them (= meaning still No improvement was achieved )"
↓ This research paper on the recent hyped news ↑
p.3-left-1st-paragraph says "Single-particle energies and band gaps are notoriously underestimated within DFT and one of the gold standards in defect computation is to use hybrid functionals such as PBE0" ← Artificial choice of exchange energy functionals of one-pseudo-electron DFT method influences the results, which is Not quantum mechanical prediction.
p.3-right-1st-paragraph says "They are only excitable optically through a transition between a localized defect state and a delocalized band level forming a bound exciton (= unreal quasiparticle model )"
p.6-Fig.5 shows scanning tunneling microscope spectroscopy without conducting any quantum communication research, contrary to hypes.
p.7-left-First-principle calculation used one-pseudo-electron DFT model with projector-augmented wave method based on artificially-chosen pseudo-potential.
p.7-right-last-paragraph says "In line with the single-shot PBE0 calculations,.. we described the defect levels using the mixing parameter α = 0.07 for the Fock exchange,... On the other hand, we used α = 0.22 for the pristine WS2" ← Artificial choice of mixing parameter α in (fictitious) DFT exchange energy functional PBE0 ( this p.1-right-last-paragraph, p.2-left-2nd-paragraph, Fig.1 ) shows this is Not quantum mechanical prediction.

p.1-abstract makes No mention of practical application nor green technology.
p.1-~p.13 shows No experiments. This research is just about hypothetical theory of one-pseudo-electron DFT.
As a result, the current useless quantum mechanical model hampers science (= which becomes useless except for publishing papers in journals ), and they need overhyped news to hide this inconvenient fact.
The 1st, 3rd, 6th, 16th, 23th paragraphs of this hyped news (7/22/2024) say
"Successfully innovating optoelectronic semiconductor devices depends a lot on moving charges and excitons—electron-hole pairs (= exciton is just a fictional quasiparticle abstractly representing an excited electron and a hole ) in specified directions for the purpose of creating fuels or electricity."
"Deriving inspiration from the natural process of photosynthesis, National Renewable Energy Laboratory (NREL) researchers developed a mixed-dimensionality (2D/1D/2D) trilayer of semiconductors to enable (fictional) exciton dissociation. This exciton dissociation step, a splitting and spatial separation of excited electron–hole pairs, is a microscopic process that is fundamental to the performance of photovoltaic systems."
↑ False. The useless quantum mechanics can only express the fictional exciton quasiparticle as a nonphysical math operator with No shape ( this p.3 ), which can never clarify the detailed real microscopic process of photovoltaic system.
"In this study, we were able to create light-activated electron hole pairs and separate them for a long time, longer than previously reported similar systems (= hype, this research just excited the material by light, and the transient excited state of the separated electron and hole lasted for only less than microseconds μs = extremely short and No practical use )"
"The study also looked at the mechanics of carrier diffusion in TMDCs (= transition metal dichalcogenides ). Using transient absorption spectroscopy, researchers tracked (fictional) exciton dissociation and charge diffusion across the hetero-trilayer, observing ultrafast electron transfer to one layer and hole transfer to the other (= false, fictional quasiparticle exciton itself was unobservable. All they measured was just the absorbed light interacting with the material )."
"Our results suggest that well-defined charge transfer cascades can result in longer charge separated lifetimes and higher charge yield (or efficient transfer), paving the way for better understanding of how charges are moving through these systems and how we can continue to optimize them.
↑ No mention of practical application, which means quantum mechanical fictional quasiparticle model just hampers science.

p.3-Figure 2. shows transient absorption spectra where the material layers were excited by pump laser light with 1000 nm wavelength, and after 2~5 ns, the absorbed probe light with about 1200 nm (= X+ ) was observed, which was (mis)interpreted as fictional Trion quasiparticle (= Fig.2-C, D ) consisting of three electrons or holes. ← Just light spectrum, No real picture of quasiparticles.
p.6-Figure 5 shows this transient excited state of an electron (= - ) separated from a hole (= + ) lasted for only picoseconds (= ps ) ~ microseconds (= μs = extremely short, so useless ), which was (mis)interpreted as fictional exciton quasiparticles with No shape ( this p.4 ). ← That's all. No practical use.
This p.13-15 used artificially-chosen parameters (for fictional exiton or trion quasiparticles ) with No quantum mechanical calculation nor prediction.

"Nvidia researchers are claiming noteworthy progress in the quest (= still unrealized ) to build a fully functional, commercially viable quantum computer based on supercomputer simulations conducted with graphical processing units ( GPUs = ordinary classical computer, this p.8-right-simulation detail )."
↑ This research is just about classical (super)computer simulation of (imaginary, still-useless) quantum computer's annealing.
So No quantum computer has been used nor realized in this research.

"The team's approach relied on nitrogen-vacancy centers in diamonds acting as qubits (= the energy levels of atoms of nitrogen-vacancy (= NV ) was used as a qubit expressing 0 or 1 state )."
↑ This research paper's p.2-Fig.1b, p.3-Fig.3-a,b used only one nitrogen vacancy (= NV ) qubit (= NV's one electron e- and one nuclear n energy states were used as the total only two qubits = just 01 two bitstring, still Not a computer at all )
↑ So this research used only 1~2 impractical qubits, far from scalable practical quantum computers that will need millions of qubits.
The last paragraph of this hyped news on some biological research (7/22/2024) just vaguely says
"The discovery of ArcS, which can utilize a nucleoside as a minimum substrate, provides new insights into the synthesis of precursor molecules for these modified nucleosides."
↑ No mention of practical use , because today's deadend biology cannot consider detailed atomic interaction due to useless basic physics or quantum mechanics.
↑ Actually, this p.11~p.13-experimental procedure used just ordinary macroscopic biological tools with No (useless) quantum mechanical calculation (= No Schrodinger equation nor DFT was used in this biological research )

Biden suddenly announced dropping out of presidential election ( as many expected ).
But if he was really a sitting president or a real candidate for presidency, why did he make an unprecedented blunder forgetting to apply for New Hampshire democratic primary ? His inauguration was also extremely weird.
Are we watching just imaginary quantum mechanical parallel worlds where the truth is hidden forever ? No progress ?
The 2nd-last and last paragraphs of this hyped news (7/27/2024) say
"We established control routines that enables to hop spins to any quantum dot in a 10-quantum dot array , which allows us to probe key qubit metric" ← this research used only less than 10 impractical (fake) spin qubits (= each atomic or electron's two unstable energy states are used as a qubit's 0 or 1 states, so this is just useless 10 bitstring ), which are far from practical quantum computer that will need millions of qubits ( this 2nd-paragraph ).
"We believe it is critical to develop efficient control schemes for the operation of future quantum computers (= just 'believe' or speculation about uncertain future, still useless quantum computers ) and this new approach is promising"
↑ This news' research paper ( this ↓ ).
p.6-Figure 1-a,e used only two (fictional) spin qubits (= QA and QB = 00, 01, 11 ) in two quantum dots (= D1, D2 ), each qubit lifetime (= coherence time T2 ) is only 7.0μs, ← this qubit is easily broken, useless.
p.9-2nd-paragraph says "each two-qubit gate fidelity is 98.6% (= 1.4% or 0.014 high error rate in each qubit operation )", which is far from practical quantum computer whose qubit gate error rate must be less than 10-15 ( this 3rd-paragraph ).
p.12-Figure 3 used only 10 (= D1 ~ D10 ) impractical spin qubits with No quantum computation nor qubit gate operation. ← They only measured fictitious magnetic g factor (= Fig.3g ), which is about 0.011~0.051, which was completely different from electron's spin g factor 2, so No evidence of electron spin (= each quantum dot showed more complicated multi-atomic effects instead of single fictitious spin qubit ).
↑ As a result, despite longtime research, even today's latest quantum computer (= still Not a computer ) has only less than 10 impractical error-prone qubits, which is far from practical quantum computer that will need millions of errorless qubits.
Quantum computer research is already deadend, needing overhyped fake news.
The 1st, 2nd, 4th, last paragraphs of this hyped news (7/27/2024) say
"Quantum information systems offer faster, more powerful computing methods than standard computers to help solve many of the world's toughest problems (= just hype ). Yet fulfilling this ultimate promise will require bigger and more interconnected quantum computers than scientists have yet built. Scaling quantum systems up to larger sizes, and connecting multiple systems, has proved challenging (= so still useless )."
"Now, researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME) have discovered how to combine two powerful technologies—trapped atom arrays and photonic devices—to yield advanced systems for quantum computing, simulation and networking (= overhype, this research has Not realized quantum computing, simulation nor networking at all ).
"Arrays of neutral atoms trapped in optical tweezers—highly focused laser beams that can hold the atoms in place—are an increasingly popular way of building quantum processors (= hype, these trapped atoms are extremely unstable, easily lost, impractical, causing a lot of errors )."
"While the team showed the feasibility of trapping an atom and moving it between regions (= they just trapped atoms unstably, and moved them, No quantum computation nor information ), they are planning future (= just speculation ) studies.. "

p.3-Fig.1c shows "imaging atoms" is based on exciting atoms with laser light, which radiated light with 895nm, which was detected as an atom (= imaging ).
p.4-left-last-paragraph says "We begin this Stark shift measurement by loading the (optical) tweezers with
atoms in the loading region (= atoms are trapped in laser light or optical lattice ), moving the tweezers between the devices,...
our modeling indicates
varying loading probabilities across the devices with a maximum loading
probability of 29% (= only 29% of atoms were successfully trapped or loaded into light or optical lattice = very unstable, unreliable trapped atoms with high error rate ) "
p.4-right-last-paragarph says " The rate of deterministic placement of atoms in Fig.4 is currently limited by "atom survival" through the first image (= unstably trapped atoms easily disappeared, could Not survive, which makes it impractical )"
p.5-left-2nd-paragraph-first-part says "The devices presented in this work are nanophotonic cavities (= mirror ) embedded in waveguides. Currently, the cavities are not resonant with the atomic transition, preventing direct atom–cavity interactions (= this research did Not connect photonic device and trapped atoms after all, contrary to hypes )"
p.5-right-last paragraph mentions the extremely-low temperature = 50μK = useless device (= trapping unstable atoms in laser light needs impractically low temperature ).
↑ Supplementary information in the above research (7/27/2024) ↓
p.3-2nd-paragraph (and Fig.S3a ) says "From the fits, we estimate an atomic lifetime of 13.6 seconds in the loading region and 0.78 seconds when trapped in the standing wave traps on top of the devices (= lifetime of unstably-trapped atoms was very short = only 0.78 ~ 13.6 seconds, which cannot make practical stable devices )"
p.4-Rearrangement says "Loading atoms into the optical tweezer array is a stochastic (= just random, unreliable ) process with a 55% loading probability (= trapping atoms in laser light is just random unreliable process with only less than 55% success rate )"
" Around 10-15% of atoms are lost
after the first round of imaging, resulting in a corresponding reduction of atomic probability in the second
image..
The remaining 23% atomic loss stems from the
losses during rearrangement (= just imaging and rearrangement of atoms caused significant loss of unstably-trapped atoms )."
↑ This research just imaged or slightly moved atoms unstably trapped in laser light lattice, and significant numbers of those atoms easily got lost in each imaging and rearrangement with a lot of errors (= bad loading success rate ), which cannot be used for any practical device.
No practical use, No quantum computation nor networking.
The 10-11th, 13th paragraphs of this hyped news (7/22/2024) say
"Chemists from the NERL fabricated the spin LEDs by stacking several layers,... the second layer's material blocks electrons having spin in the wrong direction, a layer that the authors call a chirality-induced spin filter." ← false, an electron is Not spinning, and this filter can distinguish or block only the electron's orbital motion in the wrong direction, cannot distinguish the point-like (fictional) electron spin's direction with no size (= orbital and spin magnetic moments are the same indistinguishable Bohr magneton ).
"The spin-aligned electrons (= false, not unreal spin but orbital motion ) then recombine in the third layer, a standard semiconductor used as an active layer in regular LEDs. The injected spin aligned electrons cause this layer to produce photons .. to produce the LED's signature circular polarized electroluminescence,"
↑ So this research just injected electric current with some magnetization (= caused by electron's orbit not by spin ) into LED which produced circularly-polarized (classical) light (= only this polarized light instead of spin could be measured in this research ). ← That's all. No practical use nor spin-controlled spintronics device (= this so-called spin-filter material was fixed, unable to control 'spin' ).
"However, more research is needed to explain the exact mechanisms at work to create the polarized spins." ← No clear mechanism was given to this (fictional) quantum mechanical spin which has No evidence.
↑ This news' research paper ( this ↓ ).
p.3-Fig.1 says "Device stack of the spin LED emitting circularly polarized (light) electroluminescence (CP-EL). The (R-MBA)2PbI4 acts as a spin filter, allowing only spin polarized holes to flow through the device and recombine in the MQWs emitting CP-EL (= circularly-polarized light, which was the only thing measured ).
p.7-2nd-paragraph just vaguely says
"In this study, the Spin-LED platform is used to detect spin polarized current... This could serve as a platform for

Acoustic evidence proved that there were more than one shooters in Trump assassination attempt.
This video (= 18:43~ ) showed the soft sound of first 3 shots was clearly different from the louder 5 shots after that. ← The first 3 shots probably came from inside buildings near Crooks suspect or from more distant places by 'professional shooter' hitting Trump's ear.
And the first bodycam footage finding only 5 casings around Crooks ( this 4:56~ or this 4.45~ ) seemed to be purposefully edited, or someone (= real shooters inside building ) might put additional 3 casings after that ( this 4:00~ ).
There is still no conclusive evidence that Crooks suspect himself actually fired the gun (= gun was found to be 2~3 meters away from the suspect, and no scope for magnification )
↑ Like the current overhyped fake science news, (almost all) the media continue to hide inconvenient truth ?
The 7-8th, 11-12th paragraphs of this hyped news (8/3/2024) say
"The team was interested in how these materials' magnetic properties respond when exposed to light. They were specifically interested in particular particles—the excitons (= fictional quasiparticle model ) —and how they are related to the underlying magnetism."
"A solid material is composed of different types of elementary particles, such as protons and electrons. Also ubiquitous in such materials are "quasiparticles" that the public is less familiar with. These include excitons, which are composed of an electron and a "hole," or the space left behind when light is shone on a material"
↑ The useless quantum mechanics has to rely on fictional quasiparticle model to describe material exposed to light, which pseudo-model hampers science by preventing clarifying true mechanism.
"The MIT team explored how excitons form in the nickel dihalides. More specifically, they identified the exact energies, or wavelengths, of light necessary for creating them in the three materials they studied." ← This research just measured light's energy (= wavelength) causing fictional quasiparticle exciton (= just a transiently-excited electron and a hole ) with No practical use.
"This is one essential step towards understanding how photons—light—could one day (= just speculation ) be used to interact with or monitor the magnetic state of these materials. Ultimate applications include quantum computing and novel sensors"
↑ Baseless overhype, this research just measuring X-ray light interacting with nickel dihalide (and imagining fictitious exciton quasiparticle, this 3rd-paragraph ) had No practical application, as shown in this research's p.1 abstract making No mention of (deadend) quantum computing nor sensors nor any practical application.
Overhyped quantum computers are useless except for political tools.

"Scientists have hypothesized that moiré excitons (= fictional quasiparticle model hampering science ) —electron-hole pairs confined in moiré interference fringes which overlap with slightly offset patterns—may (= just speculation, so still useless ) function as qubits in next-generation nano-semiconductors."
↑ Overhype, this research has nothing to do with the (deadend) quantum computer's qubits, as this research's p.1 abstract saying nothing about quantum computer nor qubit.
"The results show that the quantum coherence (= time responding to light ) of a single moiré exciton (= fictional quasiparticle ) remains steady at -269oC for more than 12 picoseconds"
↑ This fictional exciton state (= transient excited electron ) continued for only 12 picoseconds in extremely-low -269 degree temperature (= almost absolute zero, which is impractical ), which research based on fictional quasiparticles is completely useless except for publishing papers in journals.

"As an upshot of this contrast, the activity of electrons in conventional superconductors display symmetries that are broken in chiral superconductors, which favor flow in one direction over the other, as seen in the superconducting diode effect."
"Because chiral superconductors have been so difficult to find, engineering them from more readily available ingredients—such as in the new hybrid material reported in this study—could (= just speculation, still useless ) help unlock quantum computing's potential" ← Overhype. This research has Not used any (hyped) quantum computers at all.

p.7-Fig.2, p.8-Fig.3 also just measured the electric resistance (= R ) in different temperature (= 1.30 ~ 1.45K = impractically-low temperature ) and magnetic field Φ ( p.12- Fig.5 measured electric current I ).
p.10-1st-paragraph says "Here 𝜀(𝒌) is the (fictional) quasiparticle excitation energy with momentum k" ← Quantum mechanics always tries to (mis)interpret the observed (macroscopic) electro-magnetic properties by using fictional quasiparticle mode that hampers science and prevents clarifying true underlying mechanism.
p.13-2nd-paragraph-conclusion says
"Our study signifies the potential (= just speculation ) of hybrid superlattices with
intriguing coupling between the crystalline atomic layers and the self-assembled molecular layers.
It could chart.... offering

↑ No mention of practical use nor the hyped quantum computing, so this research is also useless due to the fictional quantum mechanical quasiparticle model that needs the fictitious scientific target = (deadend) quantum computer.
The 1st, 8th, 12th paragraphs of this hyped news (8/3/2024) say
"report that replacing lasers with less complex light sources (= lower-quality light source ) can surprisingly boost performance in some optical applications, such as light-driven AI technologies (= hype, No AI computation in this research )."
"This partially coherent light was evenly split and distributed into different input channels (= just 9 bulky input paths ) for a parallel AI computational array (= No computation, just simple light interference, this p.5 ). Using such a light source, the parallelism of AI computation is surprisingly enhanced by N times in a photonic accelerator with N input channels"
"While this work showcases the use of such partially coherent light in some emerging areas of photonic computing, we will in future (= still unrealized, useless ) also investigate whether this insight might apply to optical communications".
↑ This research just split one laser light into 9 input paths and very bulky interferometers (= each interferometer is as big as 100μm ( Fig.5a white scale bar = 100μm ), which is far bigger, bulkier and more energy-inefficient than today's practical transistor of only ~ 50nm ) with No computation, and only 3 output detectors detected the light ( this p.3, p.5 = bulky interferometers ).
The media tends to hide the inconvenient fact that the current science is already deadend with No more progress due to today's overhyped mainstream pseudo-science.
The same thing seems to be happening also in Trump shooter by intentionally ignoring real scientific facts.
All videos clearly indicate there was the second shooter, as seen this 23:10~ and this 0:43~ where Crooks suspect's shoulder did Not move at all despite the kick from the 1st shot (= hitting Trump's ear ).
Shooting his rifle (= he had No scope for magnification, which couldn't hit the target so accurately ) clearly causes the shoulder's movement ( this 2:23~ ).
Actually, the sound of the first 3 shots hitting Trump's ear was completely different from the latter 5 shots, when heard from the right side of the building ( this 15:09~ and 20:50~ = two videos confirmed ), which indicates the first 3 shots were fired from the inside of the building below Crooks.
↑ This sound difference matches the fact that the first police bodycam showed only 5 shell casings were found ( this 4:56~ ).
Later, maybe someone edited the video or put additional 3 casings.
Crooks came to this building by a bicycle that probably couldn't carry a big ladder or rifle (= 5 shots, which were too quick succession for an amateur, were probably fired by another person hiding behind Crooks ? ).
Why were secret service snipers suddendly deployed to this Trump rally for the first time ?
Anyway, like hiding the inconvenient truth of the current deadend science, (almost all) the media continues to hide these important ( real scientific ) facts ?

"Spin waves are exciting because they can carry information without moving electrons" ← This spin wave, which is just tiny transient magnetic fluctuation caused by electron's orbit instead of unphysical spin, is useless, just traveling only very short distance (= less than 10 micrometers that cannot send information ).
".. And just as light can be thought of as quantized particles called photons, spin waves have their own (fictional) quasiparticles called magnons."
"On the other hand, when atoms in a material´s lattice vibrate uniformly, this motion is described by quasiparticles called ( fictional ) phonons."
"The researchers found a new regime of coupled magnon–phonon dynamics... By tuning the frequencies of the magnons, the researchers can control this process and in particular enhance the magnon–phonon coupling." ← meaningless unrealistic research dealing only with fictional magnon-phonon quasiparticles.

"The Schrödinger equation describes the energy levels that a quantum system—e.g. atoms or molecules—can assume. This is a notoriously difficult task, and finding a solution (= fake chosen solution ) for molecules containing more than a few dozen atoms may take several days... making the computational cost quickly exceed the compute resources that are available today."
↑ Quantum mechanics Schrödinger equation is unsolvable, useless, too time-consuming to deal with multiple atoms (= so such an useless quantum mechanics was useless for inventing transistors, contrary to hypes ), which is why physicists have to rely on fictional one-pseudo-electron DFT or quasiparticle model hampering technological development.
"In the future (= just speculation ), the accurate simulation of the interaction of molecules with proteins in the human body could allow researchers to develop new drugs without the need to perform experiments" ← Overhype. This research is far from simulating practical proteins, developing drugs is far more impossible in the current impractical mainstream method.
"To showcase potential applications of the algorithm, the team used the new ML method to identify the most stable version of docosahexaenoic acid (= just a small molecule ),..

↑ As shown here, the current technology and scientific development have stopped progressing by useless quantum mechanics, DFT and extremely-time-consuming molecular dynamics (= MD ), because quantum mechanical unphysical exchange energy lacking exchange force forbids researchers from using experimentally-observed real atomic shapes.
There are many suspicious things about Trump shooters and the media's seeming cover-up like they are hyping and hiding inconvenient truth of already deadend hopeless quantum computers and true Einstein's paradox.
Judging from the clear difference between the first 3 quiet shots and the latter 5 louder shots heard from the right side of the building, the first 3 shots were probably fired from inside of some buildings, not from Crooks suspect ( this 15:09~ and 20:50~ ).
Actually, the first bodycam footage shows the police found only 5 shell casings ( this 4:55~ ).
But later the video might be edited, or someone might put 3 additional casings, 8 casings were mysteriously found ( this 4:00~ ).
Story of a police officer trying to climb up on the roof to confront Crooks before he allegedly shot is also contradictory, and whether Crooks really had a rifle or not is still unclear ( compare this 35:29~ and 37:15~ ).
The latest suspicious bodycam mysteriously without sound allegedly filming some police officer trying to climb onto the roof just before Crooks opened fire did Not show any evidence of Crooks having a gun (← this police officer was not hurt, contradicting the initial story ).
↑ The strange thing is the alleged bodycam before Crooks shot (= 7/13 18:10~ ) was clearly darker ( this shade of tree is darker despite the fine weather ) than bodycam after Crooks shot (= 7/13 18:15~, this 2:55~ shows trees were weirdly brighter than this ).
Compare this earlier 10:25~ (= mysteriously No sound, and the trees were getting darker in the evening sun ) and 15:26~ (= the sound returned. The trees and other things seemed to be brighter, weirdly = this latter footage seemed to be taken at earlier time ).
↑ Someone connected two bodycam footages of different days ? The mysteriously muted sound was necessary (= inserting artificial sounds of Trump speaking and 8 fired shots was probably very difficult technically ).
↑ This indicates this suspicious bodycam mysteriously without sound was probably not filmed before Crooks opened fire.
A video showed Crooks suspect did Not move a little despite the kick when the first shot hitting Trump ear was fired ( this 23:10~ ), which indicates he did not fire the first 3 shots (= Crooks' body or shoulders faced forward, which seemed different from the way of holding gun by turning a body a little toward right or left ).
↑ Crooks was probably told not to move by a real shooter (= of the latter 5 shots ) hiding behind him so that a distant sniper could exactly hit and silence him, as shown in this 30:15~ where someone seemed to be waving a flag to send some signal that they were ready ?
The first 3 quieter shots probably came from the inside of a building, but it was a little risky to fire shots directly from windows of the building (= of course, it is also possible ).
The video filmed by one of victims (= injured by a shooter ) clearly showed four big air ducts sticking out from the building below Crooks on the line connecting this victim and Trump.
↑ The first 3 shots were probably fired from some holes hidden behind these four air ducts ( this 0:40~ ) or from the air duct's hole itself by using some converted gun or something.
↑ When will the media start to tell the truth by accepting the real scientific evidence without contradiction (= or paradox ) ?

↑ This research paper ↓
p.1-abstract-last says "Thus, metal–single molecule–semiconductor junctions may (= just speculation ) serve as a prominent controllable platform beyond conventional nano-optoelectronics" ← This did Not specify any detailed practical application, so still useless research.
p.2-Fig.1 shows this research controlled molecular bond between a single molecule and the Ag tip of the scanning tunnel microscope by shining laser light.
p.7-Theoretical calculations used DFT treating the whole (multi-electron) molecules and the microscope's Ag atoms as one-pseudo-electron model (= spreading as fictional plane wave ) lacking real individual atomic shape ( this p.12-13 ) with artificially-chosen pseudo-potential (= No quantum mechanical prediction ).
↑ This present useless quantum mechanical fictional quasiparticle or one-pseudo-electron DFT model lacking individual atomic shapes prevents researchers from combining multiple molecules as practical parts to build useful nano-devices.
The hyped media's misleadingly colorful atomic picture with concrete atomic shape is fake, inconsistent with today's unphysical quantum mechanical model.
This p.3 4th-paragraph (= Reviewer 3 ) says "It is really necessary to use the term pico-optoelectronics ? I find this unnecessary and a bit overselling (= hyped research ). This report is by far not the first investigating light-induced molecular instabilities" ← Today's science stops progressing due to impractical quantum mechanical model.
The 2nd, 9th, last paragraphs of this hyped news (8/19/2024) say
"Now, a research group in China has shown that many entangled photons can be generated inside the myelin sheath that covers nerve fibers (= hype ). It could (= just speculation ) explain the rapid communication between neurons, "
"though the magic of quantum entanglement, communicate instantly across the involved distances." ← false, quantum entanglement cannot communicate any information, much less instantly.
"We won't say there is a direct connection (= entanglement involvement is unclear after all ). "
↑ This research paper ↓
p.2-left-1st-paragraph mentions (fictional) exciton-polaron quasiparticle.
p.8-right-1st-paragraph says "It should be noted that our model is very crude.. polaritons (= fictional quasiparticle ), which should be considered in future (= still unrealized ) studies"
↑ This research is just about a fictitious theory or model with No experimental realization.
The present useless particle physics pursues only fictional concepts such as extra-dimensions and magnetic monopole (8/19/2024) that is impossible to find except for fictional quasiparticle.
The 1st, 7th, 12th paragraphs of this hyped news ( 8/19/2024 ) say
"Researchers at the University of Chicago.. have made unexpected progress toward developing a new optical memory that can quickly and energy-efficiently store and access computational data (= hype, No memory was realized in this research ).
"...the researchers realized that the material's magnetic properties changed quickly and easily in response to light."
"perform time-resolved magneto-optical Kerr effect (MOKE) measurements, which allows the observation of magnetism" ← This research measured the slight polarization change of light reflected by material to check the material's magnetization direction.
"Yang's group is now planning (= still unrealized )... They believe (= just speculation ) that an optical memory using MnBi2Te4 could be orders of magnitude more efficient than today's typical electronic memory devices."
↑ This research paper on the hyped magnetic memory ↓
p.1-abstract made No mention of memory, data storage device nor any detailed application, contrary to this hyped news, so this research is useless.
p.2-Fig.1 illuminated material with pump light (= red pulse ), and then probe light (= blue pulse ) after a slight delay of femtoseconds at extremely low temperature (= 12K ), which is completely an impractical device (= cannot be used at room temperature ).
p.4-Fig.3E shows a slight transient magnetization change ΔM (= only 0 ~ 4% ) that lasted for only 6ps (= too short and unstable ), which too-short-lived magnetic change cannot be used for stable magnetic memory or data storage device.
p.5-left-lower shows unphysical abstract model called RKKY equation with No concrete particle picture, contrary to the hyped media's misleadingly colorful picture.
p.6-left-1st-paragraph says "the demagnetization magnitude from trMOKE (= Kerr light rotation ) is still one order of magnitude smaller than the theoretical prediction" ← Quantum mechanical theoretical prediction was false.
This p.6-1st-paragraph used fictional quasiparticle model called phonon and magnon, which hamper science.
The 3rd-last paragraph of this hyped news (8/19/2024) says
"The next steps planned by the team include on-demand release of the stored photon wave packets," ← This means today's (fake) quantum memories still cannot even release information or stored photon on-demand, which is still Not a memory at all.
↑ This research paper on quantum memory ↓
p.2-Fig.1 shows their (impractical) quantum memory tried to store X ray (= photon ? ) as kinetic energy of Fe steel foil with different velocities.
p.3-left-2nd-paragraph mentions fictional quasiparticle polariton.
p.5-left-3rd-paragraph says "which result in a total energy loss of 74%" ← 74% of information or photons were lost, completely impractical quantum memory.
p.5-right-3rd-paragraph says "The fidelity of the photon emission does Not quite reach values necessary for faithful quantum memory operation" ← useless unreliable quantum memory.
p.5-right-5th-paragraph-discussion says "The achieved storage time of about 30ns" ← Storing information or photons for only extremely-short time (= nanoseconds, Fig.2B ), which can never be a practical memory.
As shown in this, there seems to be contradiction between body cam footages and time.
This 10:30~10:38 (= 7/13 18:10 allegedly just before Crooks fired shots with no sound weirdly ) shows the position of Sun or sunlight was lower (= so the time later ? ) than this 10:01 ~ 10:04 (= 7/13 18:28 ).
This 10:30~10:38 (= 7/13 18:10 ) footage is clearly darker (= so the time later ? ) than this same video 15:43 ~ 16:33 ( = 7/13 18:15 ).
↑ This means this this video (= darker than other footages ) was probably taken at time far later than 18:10 on the day different from Trump shooting (= so No evidence Crooks himself fired shots ).
