Neutral-atom quantum computers stall every few milliseconds clearing out sites that accidentally loaded two atoms instead of one. Using Rydberg blockade — where one excited atom prevents its neighbor from exciting — plus autoionization, the team evicts the extra atom in under 65 microseconds, more than 100 times faster than the standard method. That speed-up is critical for running deep quantum circuits that require continuously refreshed atom arrays.
