When will we "outgrow" old two-slit experiments ?

[ Boring question, "Photon is wave or particle ?", continues forever ? ]

(Fig.1)   Photon is Wave or particle ? → Shut up ! → this question remains "unsolved" forever ..

Even in 21th century, we cannot progress and outgrow the boring concepts such as two-slit experiment and "photon is wave or particle ?", as shown in Scientific american.

So, even 1000 years from now, I bet we continue the same boring question such as "Photon is wave or particle ?", as long as we stick to unrealistic quantum mechanics.

Basically, as shown on this page, all experiments dealing with photons rely on wave nature (= interference, phase, polarization ) of light.

As shown on this site (= abstract ), even Willis Lamb, Nobel winner, said "there is NO such thing as a photon."

Quantum computer (= entanglement ) is a "camouflage" to conceal uselessness of quantum mechanics.

(Fig.2)   Unrealistic spin, quasiparticles → Science stops ! → quantum computer = camouflage.

Quantum mechanics is based on unrealistic spin, many-worlds (= Schrodinger's cat ), and fictitious quasi-particles.
As a result, we make NO progress, and cannot desribe physical phenomena using real concrete things.

This means the current science stops due to this troublesome quantum mechanics.
To conceal the fact that quantum mechanics obstructs our science, they created the imaginary targets such as quantum computer and spooky "entanglement".

Entanglement, superluminal spooky link ( ← unreal ), is indispensable for this "imaginary" quantum computer. This is the reason why "entanglement" often appears in journals.

In fact, as shown on this page and this news, these several qubits (= quantum computer !? ) easily break within 10-9 - 10-6 seconds (= 1 ns - μs ), completely impractical computers, forever.

Photon's speed changes depending on medium → Photon is NOT particle.

(Fig.3) Photon with light speed c becomes slower in the water, but accelerates again in the air ?

As you know, photon's speed must be always light speed "c", according to special relativity.
But for example, in the water, this light speed becomes slower than "c".

Furthermore, when it gets out of the water into the air, this photon accelerates (← ? ) again, and this speed comes back to the original speed.   Very convenient particle.

If photon is a real particle, this phenomenon depending on medium cannot be explained.
It is quite natural that we think photon is electromagnetic wave, which is influenced by surrounding medium, considering fatal paradoxes.

When a photon is emitted from electron, its energy suddenly changes !? ← ∞ acceleration !

(Fig.4) Photon is emitted from electron → its acceleration becomes "infinite" due to the sudden change.

Basically, according to the quantum field theory, the behavior of photon must be described using Feynman diagram.
Surprisingly, if the emitted ( or absorbed ) photon and electron satisfy the basic law of energy and momentum conservation, this photon always becomes virtual photon.

As shown on this page and this site, this virtual photon violates special relativity like "tachyon". This is the reason why it is called "virtual".

Furthermore, when a photon is emitted from ( or absorbed into ) an electron, this electron's momentum and energy suddenly changes.
This means the acceleration of electron at this time becomes infinity !   Impossible.

We have to consider more realistic view about lights emitted from electrons, using the whole field change and de Broglie waves, to avoid this contradiction.

Single photon detector just sees photoelectric effect ( NOT a photon ).

(Fig.5) Single photon detector can NOT prove a "particle" of photon.
detector

The Only reason why they use the word of "photon" exists in the photodetector.
But this single photodetector does NOT see photon itself. It just depends on photoelectric effect, and observes ejected electrons.

First, we cannot generate single photon directly.
By weakening coherent laser and seeing their electric current signal at photon detector, we only estimate their existence. See this site.

As a result, there is NO direct experimental proof that photon is a particle.
On the other hand, there are extremely many experimental facts that show photon is wave.

"Entanglement" (= superluminal link ) is just an illusion.

(Fig.6) Bell inequality violation is impossible in this real world.

It is said two entangled photon pair showed superluminal link called "entanglement".
In other things such as ions, superconducting qubits, superluminal links cannot be proved due to their very short ( ~μm ) distance.

The moment a photon (= A ) passes through the filter A and turns its polarization in the direction of filter A, the polarization of photon B also becomes the same as filter A, no matter how far they are apart from each other.

As shown on this page, if we use the classical electromagnetic waves, we can explain this violation as local and realistic phenomenon.

Trick is the detection threshold of single photodetector.
That's all. As Einstein said, there are NO fantasy things such as superluminal links (= entanglement ) at all.

Tricks in quantum teleportation.

[ A single photon is "divided" into two entangled photons !? ]

(Fig.7) If photon is a particle, it can be divided into two photons ?

As shown on this site (p.11), "entangled" (← unreal ) photon pair is often created by "parametric down-conversion".
In this process, a photon of wavelength λ enters some crystal, and is split into two identical photons of wavelength .

So the total energy is conserved. (= their frequency becomes half ).
But if photon is a particle, it cannot be divided so easily. This is strange.

One of the produced photon pair is horizontally polarized (= H ) light, and another is vertically polarized (= V ) light.
Though this photon pair is clearly classical electromagnetic waves, they always try to use the word of a "photon".

Polarization of photon 1 is "teleported" to photon 4 !?

(Fig.8) Teleportation of "polarization" state (= V or H ) between two different photons.

Basically, quantum teleportation cannot teleport actual things themselves like Star Trek.
It just sends a simple information such as polarization (= vertical or horizontal ), NOT superluminally.

In the exeperiment of Nature 1997 and this site, photon 1 is divided into two entangled (← ? ) photons 3,4, one of which is vertically (= V ) polarized and another is horizontally (= H ) polarized.

They tried to send (= teleport ? ) the polarization information of photon 1 to photon 4.
Unfortunately, this quantum teleportation can be completely explained by sinmple classical electromagnetic waves.

Vertically and horizontally polarized lights cannot interfere with each other.

(Fig.9) Vertically and horizontally polarized lights do NOT cause "destructive" interference.

For example, we consider the case in which photon 1 is vertically polarized, and photon 3 is horizontally polarized.
In this case, these two different-directional polarized lights cannot interfere with each other at beam splitter.

Because "horizontal" and "vertical" lights are orthogonal, and independent from each other.
As a result, we can detect these two photons at both two detectors A and B at the same time in this case.

Two photons are detected ← Polarization of two lights are different.

(Fig.10) When two photons are detected, teleportation from photon 1 → 4 happens !?   ← classical !

Here they chose the condition in which both A and B detectors detect each photon.
In this case, these two photons (= lights ) did NOT interfere with each other destructively. So they are safe.

This means in this condition, we find the polaroizations of these two lights are different and independent (= one is vertical, another is horizontal ).

As I said in Fig.7 and Fig.8, the porizations of photons 3 and 4 are always different (= perpendicular to each other ).
So in this case, we find the polarizastion of photon 1 (= vertical ) is the same as photon 4 (= vertical ), through photon 3 (= horizontal ).

They insist, this result shows teleportation of polarization from photon 1 to photon 4.
But as you see, this is NOT a weird teleportation at all. It is just classical phenomenon based on light interference.

When both photons 1 and 3 are horizontally polarized...

(Fig.11) No teleportation ?

In Fig.11, the polarizations of both photons 1 and 3 are the same (= horizontal ).
When the polarizations are the same, these lights can interfere with each other at beam splitter, because these lights point in the same direction.

Same polarizations → destructive interference → Only one photon detected.

(Fig.12) H -- H polarization → "destructive" inteference → Only one photon is detected.

When two lights have the same polarization (= horizontal, H and H ), they can interfere with each other.
They set this beam splitter so that these two lights interfere destructively.

As a result, they cannot observe both two photons at A and B detectors at the same time in this case due to destructive interference.

In this case, teleportation does not occur.

(Fig.13)

So when they observe only one photon at either A or B detector, it means photons 1 and 3 have the same polarizations.
As a result, photon 1 and 4 have the different polarizations. ( Photons 3 and 4 have orthogonal polarizations. )

In this case, quantum teleportation does NOT occur, they insist.
But as you see, this experiment only showed the classical interference of two lights. See also this site (p.10).

Tricks in quantum Cheshire cat.

(Fig.14) Neutron's spin and body are separated !?   ← Cheshire cat is real ?

Accoding to various webnews ( this site, this site ), the weird quantum Cheshire cat was observed in neutron experiment, they insist.
But unfortunately, these kinds of media just try to incite ordinary people to believe fantasy quantum phenomena.

Though they argue this experiment showed separation of "spin" and body of a neutron like Cheshire cat, the trick exists in postselection, as shown in the comments in this site.

Only detector O post-selects neutron's spin.   ← Trick.

(Fig.15)

As shown in this paper, neutron beam is split into two different paths ( I and II ) at splitter.
By manipulating magnetic fields, we suppose the neutrons in path I have right-directional spin, and the neutrons in path II have left-directional spin.

The detector H can detect all neutrons with both spins (= left and right ).
On the other hand, the detector O can detect Only left-polarized spin neutron using some special device (= postselection, ← trick. ).

When we put absorber in path II, neutrons detected at detector O decrease.

(Fig.16)

In this case, if they put some absorber in path II, the number of left-spin neutrons decreases.
As a result, the detected neutron number at detector O also decreases.

(Fig.17) When the absorber is put into path I, No neutron decrease is observed.

On the other hand, when they put the absorber into path I, the neutron detected number at detector O does NOT change.
These results are quite natural from the realistic viewpoint.

So they insist, it looks like the neutron's body exists only in path II.

Changing neutron's spin in path I causes interference in both detectors.

(Fig.18) When they make the spin direction of of neutrons in path I same as that of path II ..

In Fig.18, when they change the spin direction of ( a part of ) neutrons of path I using the magnetic field into left, these neutrons with the same spins can interfere with each other.

This interferece can be observed at both detectors H and O.

You may think it strange that the "spin" state can influence interference of neutron's de Broglie wave.
If this "spin" is some orbital motion, it can influence the direction of de Broglie wave and cause interference.

Spins of neutrons at path II changes into right, Only detector H shows interference.

(Fig.19)

On the other hand, when they change the spin of ( a part of ) neutrons at path II into right, this right-spin neutrons interfere with those in path I.
But as I said above, the detector O can detect only neutrons with left spin.

So this interference pattern can be observed Only at detector H.
From Fig.18 and Fig.19, they argue the magnetic moment (= spin ) exists Only in path I.

This is the reason why they call this state, quantum "Cheshire cat".
But as you see this page, these phenomena are just caused by spin directions and postselections at detector O. It's quite natural.

So various mass media should NOT fan confusion among ordinary people.

Neutron is wave or particle ?

A neutron is made of a electron and proton.
These electrons and protons are spreading electric fields around them.

So when these particles move, these whole fields around them also have to move ( or tansmit ), which generates some de Broglie waves in large area.

Actually, the electromagnetic waves (= one of de Broglie waves ) consists of electric (and magnetic ) fields.
This real de Broglie waves can cause the particle's interference.

Density functional theory (= DFT ) is NOT first-principle.

(Fig.20) Exchange - correlation functionals of DFT are "arbitrary".

These kinds of webnews sites ( inside-science and physicsworld ) try to stretch the interpretation of density functional theory (= DFT ) and entanglement.

As shown on this page, the DFT depends on arbitrary exchange - correlation functionals.
So they can choose convenient correlation functionals to fit computed values to experimental results.

This means DFT has NO power to predict any values.
They just adjust arbitrary functionals.
