SUMMARY:Quantum processing with neutral atoms: from analog to digital
DESCRIPTION:












Neutral-atom quantum processors have emerged as a
leading platform for quantum science, featuring coherent control of hundreds to
thousands of atomic qubits. In this talk, I will discuss recent results
leveraging high-fidelity control of Rydberg atoms for both quantum simulation
and quantum computation. First, we combine efficient many-body analog evolution
with fully programmable digital control to realize and probe an
out-of-equilibrium critical quantum spin liquid of the Rokhsar-Kivelson type,
using loss detection for error mitigation and local single-qubit gates to
measure in arbitrary bases. Second, to achieve precise computation, we utilize
reconfigurable arrays of up to 448 neutral atoms to experimentally explore the
key elements of a fault-tolerant quantum processing architecture, including
below-threshold error correction, fault-tolerant gate operations, universality,
and physical error removal during deep-circuit computation. These results
demonstrate neutral atom arrays as a versatile platform for programmable
quantum simulation and establish foundations for scalable, universal
error-corrected processing.
