Quantum computer is useless
Topological quantum computer is fiction
(Fig.1) Even one quantum bit (= one qubit can take only 0 or 1 ) of unreal Majorana quasiparticles has Not been realized in illusory topological quantum computers despite decades of fruitless researches. So Microsoft repeats baseless lies again.
Microsoft blatantly repeats a false claim that they finally created a Majorana-2 topological quantum computer with 12 qubits with the help of AI, that will be practical in 2029 ( this-5~6th-paragraphs ).
Like IBM and other fraudulent companies, Microsoft repeatedly lied about when practical quantum computers would come ( this-Myth-4 ) or be commercialized first.
In 2018 or 2017, Microsoft boldly said they could make practical quantum computers within just 5 years (= practical quantum computers in 2023 ?, which turned out to be untrue this-7th-paragraph, this or this-4th-paragraph ).
In 2015, Microsoft said practical quantum computers could come within 10 years (= in 2025, which also turned out to be a lie ).
Contrary to a lot of overhyped fake news, Microsoft or other researchers have Not realized even one qubit (= one qubit takes only 0 or 1 value ) of unreal Majorana quasiparticle with illusory fractional charges ( this-p.3-left-1st-paragraph ) in the pie-in-the-sky fault-tolerant topological quantum computers.
This or this or this-3rd~4th paragraphs say -- No Majorana qubit
"In this paper, there’s nothing that shows that this is a qubit"
"I believe this is just another step in Microsoft’s almost a decade long track record of publishing unreliable results"
See this or this or this-middle~ The Skeptical community
↑ These quasiparticles with fractional charges such as Majorana ( this or this-20~22th-paragraphs ) and anyon used as qubits for topological quantum computers are unreal (= a real electron can not break into fractional charges ), just meaning some electric conductance.

2nd-paragraph says -- Unreal quasiparticle
"latest quantum chip Majorana 2, for the theoretical quasiparticle (= unreal particle, this-key takeaway ) it aims to use as the basis for a new “topological” approach to quantum computing."
5th-paragraph says -- No majorana qubit
"In 2021 Microsoft retracted a high-profile Nature paper after outside experts pointed out that the study’s data could have come from material imperfections rather than a topological qubit. Physicists have raised similar concerns about several publications since, as well as about last year’s announcement of the Majorana 1 chip (= fraud ) based on the disputed technology."
8th-paragraph says -- Microsoft lies again
"You can see something amazing in one device and never see it again because it’s just some random artifact"
9th-paragraph says
"The new result simply isn't up to the physics community’s standards"
This or this site on illusory Majorana-2 qubits ↓
2nd-paragraph says -- Microsoft Majorana fraud
"But critics maintain that the paper reporting the improved qubit lacks evidence that the device actually works. “The Microsoft Quantum project follows a sustained pattern of unreliable claims"
10th-paragraph says -- No Majorana qubit
"there's No evidence their device actually works as a qubit"
2nd-last-paragraph says -- Unreal Majorana qubits
"You go to a conference and somebody mentions Microsoft and people are chuckling.. It's become a joke and it's terrible for the field. To achieve a scalable quantum computer in 3 years, Microsoft researchers would likely need to have a prototype running in the lab now,.. that scenario is implausible,"
5th-paragraph says -- Just electrons, No Majorana
"These qubits are built from tiny superconducting wires, and the parity indicates whether there is an even or odd number of electrons within the wire"
7th-paragraph says -- No Majorana qubits
"Nothing in this preprint resolves the fundamental issues,"
8th-paragraph says -- Electrons = illusory Majorana
"Microsoft's device hinges on the existence of groups of electrons that collectively behave like one entity, creating a particle-ish thing called a Majorana (= unreal quasiparticle ). Pairs of Majoranas can store information in a way that is resistant to errors (= just speculation ). In the device, a Majorana sits at each end of a thin superconducting wire. Two parallel wires, connected like an H, together form a single qubit with four Majoranas."
The last-paragraph says -- No quantum computers nor qubits
"Nothing in the presented data proves the existence of a topological qubit or Majoranas in these devices,"
Microsoft cannot make even one Majorna qubit despite extremely long years of researches and hypes.
As a result, their exaggerated claims that their Majorana-2 quantum computers with 12 qubits ( this-6th-paragraph ) created with the help of AI will discover drugs and threaten cryptography soon turned out to be a total lie.
This-11th-last-paragraph says -- Hopeless quantum computers
"Important to note that the current device still remains far from a commercially useful quantum computer. "
