MWITA-QE-2026-002 · Evidence ungraded · P1
USTC reports one million random-circuit samples in hundreds of seconds and estimates 5.9 billion years for a classical supercomputer on that benchmark.
Counterevidence & uncertainty
The classical figure is an estimate sensitive to algorithms, hardware and assumptions; it is not evidence of advantage on useful workloads.
What would change the reading
Update with improved classical simulation results or revised sampling validation.
