Advancing quantum science with hybrid atom arrays

POSTER

Abstract

We report on an experimental platform that implements a hybrid neutral-atom architecture combining long-coherence ¹⁷¹Yb nuclear-spin qubits with collectively enhanced ⁸⁷Rb ensembles serving as ancillas. Both species are independently loaded and transported with a movable optical lattice into a dedicated science region. There, distinct storage-array zones allow selective atom replenishment into the processor zone, enabling continuous quantum processing. By exploiting controlled interspecies interactions demonstrated in our group through Förster resonances, our proposed schemes, like reconfigurable local addressability, EIT-based fast non-destructive qubit readout, and quantum-error syndrome extraction, become experimentally accessible. Our hybrid architecture provides new approaches towards scalable, fault-tolerant quantum computation with neutral atoms, and frontier investigations of quantum information dynamics.
