The Google Supremacy Experiment: Data, Information, Discussions, and Three Questions.
Yosi Rinott, Tomer Shoham, and I wrote a manuscript regarding our study of the Google 2019 supremacy experiment. This is still a draft and comments or corrections are most welcome. (The paper already incorporates a few comments by the Google … Continue reading
Ordinary computers can beat Google’s quantum computer after all
Science magazine has an article written by Adrian Cho Ordinary computers can beat Google’s quantum computer after all. It is about the remarkable progress in classical simulations of sampling task like those sampling tasks that led to the 2019 Google’s … Continue reading
The Argument Against Quantum Computers – A Very Short Introduction
Left: Gowers’s book Mathematics a very short introduction. Right C. elegans; Boson Sampling can be seen as the C. elegans of quantum computing. (See, this paper.) Update (January 6, 2021): Tomorrow January, 7, 8:30 AM Israel time, I give a … Continue reading

The story of Poincaré and his friend the baker
Update: After the embargo update (Oct 25): Now that I have some answers from the people involved let me make a quick update: 1) I still find the paper unconvincing, specifically, the few verifiable experiments (namely experiments that can be … Continue reading

Noisy quantum circuits: how do we know that we have robust experimental outcomes at all? (And do we care?)
In a recent post we discussed Google’s claim of achieving “quantum supremacy” and my reasons to think that these claims will not stand. (See also this comment for necessary requirements from a quantum supremacy experiment.) This debate gives a good … Continue reading
