摘要

我们报告了超过 1000 个原子量子比特的大规模量子处理架构的实现情况。通过平铺多个微透镜生成的镊子阵列(每个阵列由独立的激光源操作),我们可以消除激光功率对可分配量子比特数量的限制。通过两个独立的阵列,我们已经实现了 3000 个量子位点的二维组合配置,平均拥有 1167(46)个单原子量子系统。两个阵列之间的原子转移可以高效实现。因此,用来自次级阵列的原子对被指定为量子处理单元的阵列进行超充,可以显著增加量子比特的数量和初始填充分数。这极大地增加了可实现的量子比特簇大小和成功概率,使我们能够展示多达 441 个量子比特簇的无缺陷组装,并在数十个探测周期内持续稳定在接近统一的填充分数。所提出的方法通过促进可配置的高度可扩展量子寄存器几何结构,证实了中性原子量子信息科学,可立即应用于雷德伯格态介导的量子模拟、容错通用量子计算、量子传感和量子计量。

Supercharged two-dimensional tweezer array with more than 1000 atomic qubits
We report on the realization of a large-scale quantum-processing architecture surpassing the tier of 1000 atomic qubits. By tiling multiple microlens-generated tweezer arrays, each operated by an independent laser source, we can eliminate laser-power limitations in the number of allocatable qubits. Already with two separate arrays, we implement combined 2D configurations of 3000 qubit sites with a mean number of 1167(46) single-atom quantum systems. The transfer of atoms between the two arrays is achieved with high efficiency. Thus, supercharging one array designated as the quantum processing unit with atoms from the secondary array significantly increases the number of qubits and the initial filling fraction. This drastically enlarges attainable qubit cluster sizes and success probabilities allowing us to demonstrate the defect-free assembly of clusters of up to 441 qubits with persistent stabilization at a near-unity filling fraction over tens of detection cycles. The presented method substantiates neutral atom quantum information science by facilitating configurable geometries of highly scalable quantum registers with immediate application in Rydberg-state-mediated quantum simulation, fault-tolerant universal quantum computation, quantum sensing, and quantum metrology.
