Willow's Adaptive Control and the Evidence Trail

Learning during computation is not a finished quantum computer.

A Nature report about Willow is described as combining calibration and computation in a reinforcement-learning loop to stabilize a logical qubit while work continues. The account identifies an experimental control approach, not a finished general-purpose quantum computer. Its broader lesson for automated systems is to preserve the inputs, model version, hardware context and permissions behind a result. Adaptive correction and auditability solve different problems: improved behavior is most useful when another reviewer can reconstruct what changed rather than trust an unexplained output.
