quantum computing reproducibility crisis?

While standing in a train to my mother’s house in Brittany, I was catching up on earlier Nature issues and came upon this April issue where, following the retraction of a Nature paper on the topic, Sergey Frolov casts doubt on the possible detection of a new type of quantum particle, the Majorana fermion, whose existence still remains inconclusive. The criticism concentrates on the data analysis of signals where the appearance of a narrow peak should support the hypothesised existence. The article is interesting (to me) as a reflection of someone having published positive, then negative articles on the topic, upon the tendency for authors in the field to cherry-pick experiments where some peaks occur. Among dozens or hundred of experiments where they did not. And calling for open data and more stringent review(er)s on the matter (and others). The arguments in the opinion tribune sound most reasonable but I wonder whether or not other particle physicists share the same concern.

Tomorrow noon, I will give a talk at Trinity College Dublin on the asymptotic properties of ABC. (Here are the slides from the talk I gave in Berlin last month.)
