Next-Generation Rydberg Atom Array Quantum Testbed*

Rydberg atom arrays have emerged as one of the leading platforms for quantum computation and simulation, with systems already consisting of hundreds of physical qubits and gate fidelities surpassing quantum error correction thresholds. Further scaling of this system requires maintaining this exquisite level of control over orders of magnitude more physical qubits and pushing two-qubit gate errors significantly farther below threshold, all while continuously reloading the small fraction of atomic qubits lost during gate operations. A new Rydberg atom array experiment is becoming operational at Harvard, and aims to be a testbed for the technical advancements required for this scaling. In this presentation we will describe our efforts along these directions.
