我们成功构建了目前最大规模的碱土原子光镊阵列，装载了超过2400个镱-174原子。通过光助碰撞增强装载机制，我们利用蓝失谐光诱导的排斥性原子间势能，实现了高扩展性的单原子装载。该机制具有广泛的适用性，可适配多种原子种类，并展现出良好的规模拓展能力。我们在2400个点位的规模阵列中实现了83.5(1)%的高效率——这是首次在千级规模阵列中成功实现增强装载。基于这一平台，我们进一步提出了量子比特编码与里德堡门方案，预计可实现高达99.9%的双比特门保真度，为构建实用化量子计算平台奠定了重要基础。

We have successfully constructed the largest alkaline-earth-like atom optical tweezer array to date, loading over 2,400 Yb-174 atoms. Through an innovative light-assisted collision-enhanced loading mechanism, we utilize blue-detuned light to induce repulsive interatomic potentials, enabling highly scalable single-atom loading.This mechanism exhibits broad applicability, accommodating various atomic species and demonstrating strong scalability. We achieved an efficiency of 83.5(1)% in an array of 2,400 sites—marking the first successful demonstration of enhanced loading in a thousand-scale array.Building on this platform, we further propose a qubit encoding and Rydberg gate scheme, with an estimated two-qubit gate fidelity as high as 99.9%, laying a crucial foundation for the development of practical quantum computing platforms.
