Closing the "Quantum Supremacy" Gap: Achieving Real-Time Simulation of a Random Quantum Circuit Using a New Sunway Supercomputer — mentioned by Whirl

First I heard of these exascale computers was when a Chinese group published[1] a pre-print in which they classically replicated the Google quantum supremacy result in about 300s. The Google team estimated that a supercomputer (Summit) would take 10e3 years to do the task, which apparently really got to the classical HPC community. [1] https://arxiv.org/abs/2110.14502

I wouldn't trust the claim it can't be simulated; right after google declared quantum supremacy another group noticed that the classical solution was actually much faster than google said (and that's before any real optimization work gets started). https://arxiv.org/abs/2110.14502 Also as pointed out, these aren't full qubits, nor does any doubling mean the QC will suddenly be able to do anything useful.
