Google’s Quantum Computer Learns From Its Own Errors in Real Time

Google researchers demonstrated a quantum computer that uses AI to continuously calibrate itself during operation, replacing periodic recalibration. The system, tested on Google’s Willow processor, made logical error rates 3.5 times more stable under hardware drift and cut error rates by 20% beyond conventional tuning. This addresses a key engineering challenge for large-scale quantum computers that must run for days without interruption.
