Microsoft’s Majora Quantum Computer
John Brecher / Microsoft
Microsoft last month, with Fanfare, announced that he created a new type of topic used to make quantum architecture on the computer This can lead to machines “Of years not able to solve industrial scale problems, not in decades“.
Since then, the giant technology giant has come to more and more under the fire, researchers who say that they did. “My impression is that the response to the expert physics community has been incredibly negative. In private, people are angry,” he says Sergey Frolov At the University of Pittsburgh, Pennsylvania.
Microsoft’s claim is based on the elusive and exotic quaastiples named Majorana Zero modes (MZMS). These can theoretically use the creation of a topological qualio to create a new quantum bit – information treatment blocks within a quantum computer. For their properties, such utilities could be excellent when reducing errors, facing a large shortage of all quantum computers currently using.
MZM has been theorized to extract the collective behavior of electrons, threads on the edges of thin supercycles. Microsoft’s Majorana 1 Chip has several such threads and, according to the company, eight mima for the topological topological. A Microsoft spokesman said New scientist chip “for us and industry” important progress “.
However, researchers said Microsoft does not provide enough evidence to protect these claims. Along with his press announcement, the company published a paper in the magazine Nature He said he confirmed his results. ” Nature Reviewed review of paper because Microsoft has not been able to create Majority particles, which help protect quantum information, but they can measure this information reliably from them ” said Microsoft Press Release.
But at the editors Nature He specifically clear that this statement was incorrect. Peer-review process available on public report: “Editorial groups indicate that the results of this manuscript do not indicate that there are no evidence on the presence of the presence of Malaania’s zero modes”.
In other words, Microsoft and Nature They are directly contradicted each other. “Press notes say something completely different (than Nature paper) “, he says Added to Henry St. Andrews University of the United Kingdom.
This is not the only orthodox side of Microsoft paper. LEGG stated that there were two critical and negative feedback from four evaluators, with his experience, disqualified a paper on the normally publishing. Peer-Review report shows the last round of the last edition, a reviewer is still not agree with publishing paper, and the other three were signed there. Spokesperson Nature other times New scientist The final decision to publish was to see the potential for future MZMs for future MZMs than what he got so far.
Even one of the evaluators is unusual, Hao Zhang In China Tsinghua University, he worked with MCM before Microsoft, according to Legg. This work, published Nature In 2018, he later retreated, apologized with the team “enough scientific rigor“Researchers after other researchers identify inconsistencies.” It’s pretty moving that Nature He chose the judge that he dropped a piece of paper a few years ago, “Legge says.
Zhang says there was no conflict of interest. “I’ve never been a Microsoft worker or even affiliate (business). Among the latest Microsoft paper 100+ authors, I’ve been working for three before,” he noted. “That was seven years ago, and at the time the students were Tu Delft (in the Netherlands), not Microsoft staff.”
Microsoft says that his team was not selected by any evaluator and aware of the participation of Zhang after the review process is completed. Nature According to the decision, with a spokesperson “the quality of advice received can be seen from reviewers’ comments.”
Aside from review issues, Legg and Frolov have more fundamental objections to Microsoft methodology. Mzms experiments have been very difficult to carry out in recent decades, in fact, the imperfections and disorders on the device can cause wonderful signs that imitate quastiparticles, although they are not. It has been a challenge for Microsoft related researchers, among other things, he retreated in the 2018 paper – explicitly refunds in retraction notes. To do this, in 2023, in Microsoft He published the procedure in the magazine Physical opinion b The “topological gap protocol”, which he proclaimed would bend these differences.
“The whole idea of this protocol was a binary test, whether Malmanas is there,” Legge says. His Own code of code and data However, Microsoft used to implement this protocol in 2023, however, he showed more reliable than expected, having enough data formatting failed to fail. Legg says Microsoft raised these issues before posting Nature The paper, but the company used the protocol in his new study.
NatureThe spokesman says the magazine’s editorial is “aware” that they have been aware that sometimes they question the validity of the topological protocol Nature Paper and other publications. This was also a peer review process. “Through this process, evaluators determined that this was not after all, the spokesman says.
Microsoft said LEGG will respond to his 2023 paper examination if requested Physical opinion B. “Critique Legg is attacking our fake paper straw and then attacks,” Chetak said Microsoft. He discusses Legg’s work at a number of points and said that the papers of 2023 “showed that the topological phase and the Majora zero way can only trust” and reinforces these new paper claims.
A Microsoft spokesman says, since the year Nature It was presented to review the paper, built by the company in this trust, but not only creating a multi-chip Qubit, it has also tested ways to manipulate these holes, because it would be necessary for work on the quantological computer work. The firm will release more details at the American Fision Society’s Physics Summit in March, the spokesperson said. “We look forward to sharing our results for our 20 years of 20 years of contemporary reality.”
For Frolov, however, it can be claimed that the imperfect results of the past can be ignored, because the company has gone to build more sophisticated devices in defective logic. Legg shares this view. “The basic problems of mixing and science materials will not be left, when you start making fan fans,” he noted.
