IBM and University of Chicago researchers used a new error-correction technique to encode 70 logical qubits and complete a random circuit sampling task in roughly 15 minutes, a computation that would take leading classical supercomputers an impractical amount of time. The team also designed a more structured circuit approach to verify that the quantum output was actually correct, addressing a longstanding challenge in confirming quantum results once problems exceed classical checking ability. The circuits and data have been published via the Quantum Advantage Tracker.
