講演概要
Neutral atoms have emerged as a strong candidate for scalable, fault-tolerant quantum computing. A popular approach for neutral atom gates involves shuttling atoms to and froma shared interaction zone.While atomshuttling enables parallel execution ofmultiple gates, local qubit addressing comes with distinct advantages, such as faster overall execution speed and the ability to perform non-identical gates in parallel. We present benchmarking results from a full-stack universal quantum computing architecture featuring individual optical addressing of single atoms for fast gate execution without the requirement for atom shuttling. We demonstrate reduction in computational error by encoding physical qubits into logical qubits using the [[4,2,2]] quantum-error-detecting codewhere performance is evaluated by executing a variety of quantum circuits with and without logical encoding. We show that logical performance surpasses physical performance for Bell state generation (12x error reduction), Gottesman random circuits (15x), and an Anderson ImpurityModel ground state solver formaterials science applications (up to 6x). Finally, we present preliminary results on scaling to larger qubit arrays and implementing more complex quantum error correction codes, laying the groundwork for larger, fault-tolerant systems.
