Majorana: mysterious disappearance of a particle and of credibility
The theoretical physicist Ettore Majorana mysteriously disappeared in 1938. Unfortunately, Majorana particles are also going to be associated in history with some mysterious disappearances: their own existence, the prospect of a topological quantum computer, some prominent scientists' reputations, and the credibility of Physical Review journals. Nine years ago I expressed skepticism that there would ever be a quantum computer based on Majorana fermions. I wish I was wrong. It certainly would be cool. Things are even worse than I thought. The issues (scientific, ethical, technological, hype, ...) were recently highlighted in a strange incident involving a paper from Microsoft that was published by PRB. I found the commentary of Vincent Mourik on the whole incident enlightening and disturbing. His description is "Here's the full background of my involvement with the recent Microsoft Quantum paper.
