The physicist threw a test behind a high -level claim by Microsoft to create the first “Qubits”, a long goal required for the company’s quantum computing effort. Criticism comes amid an escalating speculation about the validity of Microsoft.
Microsoft Declare the breakthroughWhich can lead to a more resistant quantum computer for the loss of information than other methods, on February 19. Without a pair, the peers support the claim, some researchers were skeptical. Paper accompanying in nature Description of a way to measure reading from future Qubits, but it has not provided evidence of its existence1.
“while nature “The paper has made our approach, it does not speak to our progress,” Microsoft spokesman said in a statement. They said that the paper was presented almost a year before its publication and since then “there has been a tremendous progress.” ((natureThe news team is independent of the magazine team.)
In the latest criticism, it was published as a prior power2Henry Leg, a theoretical physicist at St. Andrews University, UK, raises Fears about the test Microsoft is used to search for majuranas, so as not to discover the non -discovered particles that arise from the collective behavior of the required electrons until the Tobits operates.
Known as the TGP, the test was not mentioned in the Microsoft Declaration on February 19. But the company then referred to natureThe news team, and in a Comment on the InternetIt created the TGP Qubits using TGP. “Since TGP is defective, the Qubit itself does not exist,” says Legg.
Citan Nayak, a theoretical physicist who leads the quantum computing efforts of Microsoft in Redmond, Washington, stands alongside Qubit’s claim. He says: “Criticism can be summarized as building a false straw man from our paper and then attacks it.”
MAJORANA test
Maguranas has previously proven. Several alleged scenes later proved that they mimic Majurana, in some cases, which led to a decline.
In 2022, Microsoft researchers Preprint post Reporting that TGP can indirectly define majuranas with a “high probability”; Preprint was later published in Physical review b ((Prb))3. The test depends on the electronic measurements of the microscopic sandwiches of high minerals. If the analogy shows a specific feature of majoraanas features, the “passes” device is said to host the bodily particles.
Legg and his colleagues at Basel University in Switzerland continued to report that the test could be fooled by false positive4.
At the last criticism, LEGG reports on defects with the protocol. Data check in Prb Paper, he saw major differences in external conditions, such as the scope of magnetic field strengths, when conducting electronic measurements. The test is designed to measure the essential properties of the device – and thus whether it contains majoraanas. Instead, the Legg found that the different conditions have made the Weathervane test inconsistent.
Nayak does not accept this criticism. “The ranges come from an initial examination that we described, and we always analyze full data,” he says.
LEGG, another problem, says that the main parameter of the code that carries out the protocol, which is shared by Microsoft publicly, differs from the description in Prb paper. When the Nature News team was asked about the case, Nayak said: “Legg claims that there is a difference between our described protocol and the implemented symbol. This is not true, so this is not an issue.” I admit this difference in an email to it He plans to issue a correction, but he changed his opinion.
Carlo Baker, a theoretical physicist at the University of Leiden, the Netherlands, says, although he is still “excited” about Microsoft’s goal of creating a Tobology quarter. “I have a deep respect for people who are essentially coming out and in some way their attention is not paid by others who say:” I can’t believe it. ”
“Legg’s criticism requires a general response from Microsoft researchers,” says Anton Akhmerouf, a theoretical physicist at Delft University of Technology in the Netherlands. A Microsoft spokesman said they would formally respond to LEGG’s criticism when contacting it by the OF editors Prb.
