Two Skoltech research units — the Laboratory for Quantum Information Processing of the Skoltech center of Photonics & Quantum Materials (CPQM) and the ‘Zhores’ supercomputing team of the Skoltech Center for Computational and Data-Intensive Science and Engineering (CDISE) — have teamed up to emulate Google’s quantum processor.
Reproducing noiseless data following the same statistics as Google’s recent experiments, the Skoltech teams were able to point to a subtle effect lurking in Google’s data. This effect, called a reachability deficit, was discovered by Skoltech researchers in past works. The numerics confirmed that Google’s data was on the edge of a so-called, density-dependent avalanche, which implies that future experiments will require significantly more quantum resources to perform quantum approximate optimization. The results are published in the field’s leading journal Quantum.
