光镊中低熵原子量子系统阵列为少体与多体系统基础研究及量子技术扩展应用提供了独特前景，该方法的价值取决于可实现的系统规模、均匀性和量子比特分配速率。我们通过一种新型的强度均匀化光镊阵列实现方案及并行化原子输运，推进了中性原子量子技术平台，快速组装出最大含1024个原子量子比特的规则二维量子寄存器。我们的高效微光学架构将强度均衡与光镊图案化模块化至独立功能单元，消除了单设备内高功率、高分辨率及大规模光场控制带来的限制；演示了超过3500个位点的精确网格结构、阱深和振动频率阵列，单个位点间通过最多50个并行化输运光镊互连，这些光镊可实时控制强度与位置以实现快速量子比特重定位；多光镊输运可操作最大32×32位点的目标图案，且维持近1的填充率。这些成果将中性原子量子信息科学提升至千量子比特级别以上。
英文摘要
Low-entropy arrays of atomic quantum systems in optical tweezers offer unique prospects for fundamental research on few- and many-body systems as well as for extended applications in quantum technology. The significance of this approach relies on the achievable system size, its uniformity, and the rate of qubit allocation. We propel the neutral-atom quantum-technology platform by the rapid assembly of a regular two-dimensional quantum register of up to 1024 atomic qubits, enabled by a novel implementation of intensity-homogenized tweezer arrays and parallelized atom transport. Our highly efficient microoptical architecture modularizes intensity equalization and tweezer patterning in separate functional units, eliminating restrictions that arise for high-power, high-resolution, and large-scale light-field control within a single device. Arrays of precise grid structure, trap depth, and vibrational frequency with more than 3500 sites are demonstrated. Individual sites are interconnected by up to 50 parallelized transport tweezers with intensity and position control in real-time for swift qubit relocation. Multi-tweezer transport enables the operation of target patterns of up to 32 x 32 sites with sustained near-unity filling fraction. These results boost neutral-atom quantum information science above the kiloqubit level.
