Pasqal’s Neutral-Atom Processor Uncovers Quantum Magnet Behavior That Theory Did Not Predict

Pasqal's 256-qubit neutral-atom processor revealed unexpected behavior in a 2D quantum magnet: after being disturbed, the system settles far more slowly than theory predicts. The result was published as an arXiv preprint with the Flatiron Institute and four European institutions, in a regime where three state-of-the-art classical simulation methods diverge from the measurements and each other.
