This is the paper: https://arxiv.org/abs/2009.11482 https://arxiv.org/abs/2009.11482 It's actually from last year, and other groups have done better experiments since then (in particular, experiments doing multiple rounds of correction instead of just immediately smashing the system and analyzing the pieces). It's quite funny to see a big deal being made of this paper now rather than a year ago.
