Nearly a year after marking a paper on the elusive “Majorana” particle with an expression of concern, and almost three years after publishing a critique of its reproducibility, Science has retracted the article due to “serious irregularities and discrepancies” in the data.
A few papers about Majorana particles, which would be useful in quantum computing if scientists could indeed produce and detect them, have been retracted, flagged with expressions of concern, or otherwise proven difficult to reproduce.
The latest article to be retracted, “Chiral Majorana fermion modes in a quantum anomalous Hall insula- tor–superconductor structure,” has been cited more than 400 times since it was published in 2017, according to Clarivate’s Web of Science. About 10 percent of those citations have come since Science’s editors published their expression of concern last December.
The retraction notice states:
