EINDHOVEN — Qubit readout breakthrough: first single-shot in-situ measurement in a compact, foundry-made spin qubit unit cell. Operates at 1 K. Charge noise tamed. Scaling within sight. Integrated readout eliminates cabling choke point.
EINDHOVEN, 16 JANUARY —
Cold silicon trenches hum at 1 kelvin, their quantum dots holding spins like bayonets at rest. Here, in a foundry-bred unit cell, the long stalemate in readout has broken. No more off-chip detectors, no snaking wires—readout is now in situ, dispersive, single-shot, and swift. Two electron spins, exchange-controlled, initialized and entangled under microwave fire. The signal—sharp, clean—rises from the noise floor like a clarion. Charge noise measured via free induction decay: among the lowest ever recorded. This is not a laboratory curiosity. It is fabricated, stable, scalable. The architecture breathes industrial rhythm. If massed, such cells could form the first true quantum arrays. Yet silence remains the enemy. Without broader integration, this victory stands isolated. The path to fault tolerance demands more—faster gates, colder control, wider arrays. Delay risks irrelevance.
