A dual-element, two-dimensional atom array with continuous-mode operation

POSTER

Abstract

Quantum processing architectures that include multiple qubit modalities offer innovative strategies for high-fidelity qubit manipulation and readout, quantum error correction, and a path for scaling to large system sizes. We present a programmable quantum device based on a dual-element neutral atom array composed of Rb and Cs atomic qubits in up to 512 trapping sites [1]. Our observation of negligible crosstalk between the elements enables a new continuous mode of operation for atom arrays without any off-time. We report recent progress towards inter-element Rydberg gates and describe avenues for mediated multi-qubit gates, efficient production of large-scale entanglement, and ancilla-assisted quantum protocols such as QND measurements and quantum error correction.
