Researchers of 'Majorana fermion' explain why papers on quantum computers are being withdrawn one after another
Much research is being done toward the practical application of
Quantum computing's reproducibility crisis: Majorana fermions

The Majorana fermion is a particle whose existence was predicted by Ettore Majorana in 1937, and many studies have been conducted aiming at the generation and observation of the Majorana fermion as it is useful for the development of quantum computers.
According to Mr. Florov, by the time of writing the article, more than 100 research groups have challenged the generation of Majorana particles, and reports have been submitted that produced Majorana particles from about 20 groups including the research group in which Mr. Florov participated. It was said that. However, in 2020, the verification result that the research report of Majorana fermion published in 2017 is incorrect was announced, and Mr. Florov's research group also published a counter-evidence paper of the research report published in 2018 2021 Published in January of the year.

As mentioned above, the fact that research reports on Majorana fermions have been disproved and withdrawn one after another 'has impaired the reliability of research on Majorana fermions,' Mr. Florov pointed out. 'Students asked me if I would like to continue my research on Majorana fermions, and the grant examiner was skeptical about what I was doing,' said Florov.
According to Mr. Florov, a huge amount of data can be obtained in the Majorana particle generation and detection experiments. From this data, data that is not useful for proving the hypothesis is excluded as 'outliers', and only data that seems to be useful is extracted and used in the treatise, which is the cause of frequent false research reports. He insists.
Florov also points out that research on Majorana fermions is a combination of a wide range of research fields such as nanotechnology, superconductivity, materials engineering, and device engineering, which is also a cause of frequent false research reports.
Papers are usually reviewed by an expert before being published in an academic journal. However, there is a bias in knowledge depending on the expert in charge of the examination, such as 'Experts in theoretical physics are accustomed to' evaluation of calculations 'but not' evaluation of experimental processes '.' That is. Majorana's research treatises cover a wide range of research areas, making it difficult for them to be properly reviewed by experts, Florov said.
Florov argues that the code of conduct of the community needs to be revised to reduce false research reports and restore confidence in research on Majorana fermions, and proposes to publish experimental data and methods on Majorana fermions. .. By disclosing the data, 'The reliability of the research is improved, collaboration between research groups is promoted, and the research is speeded up. Also, by disclosing the data, it is possible to accurately review the research report. Will be. '
In addition, Mr. Florov said that there is something like a 'secret sauce' about experiments, saying that 'simply sharing data does not mean that we can grasp everything that is being done in the laboratory.' Introduction. He responded to this opinion by saying, 'Solid and useful science is based on a reliable process and can be reviewed as many times as needed,' and the usefulness of publishing data. I emphasize it.
In addition, in order to improve the process of reviewing the treatise, Mr. Florov asked the experts in charge of reviewing the treatise, 'Is the result true?' 'Is sufficient data presented?' 'Other ideas are considered. We are requesting that we consistently perform checks such as 'Is it done?'
In addition, in order to solve the current situation that 'most academic journals do not have a mechanism to conduct their own research on false claims', the editorial department of academic journals and the research community should work together to build a research posture. Is also proposing.
'It is only after these improvements have been made that we are ready to develop a quantum computer using Majorana particles,' Majorana concludes.
