Other researchers in the field flagged doubts over errors in the data, while Nature tacked an ‘editorial expression of concern’ to the paper.
A Microsoft researcher has revised a paper on quantum computing due to “technical errors”, in a blow to the company’s quantum efforts.
In 2018, Leo Kouwenhoven, a physicist working for Microsoft, published a paper claiming that he and his co-authors had observed a particle called a Majorana fermion, which could be used to develop a quantum computer.
However, Wired reports that the authors have now published a new paper correcting errors in the 2018 paper that was published in Nature. The authors added that a retraction note is being prepared for Nature, which will include a “detailed description of errors and the corrected data analyses”.
