Arrays of neutral-atom qubits in optical tweezers are a promising platform for quantum computation. Despite experimental progress, a major roadblock for realizing neutral-atom quantum computation is the qubit initialization. Here we propose that supersymmetry, a theoretical framework developed in particle physics, can be used for ultrahigh-fidelity initialization of neutral-atom qubits. We show that a single atom can be deterministically prepared in the vibrational ground state of an optical tweezer by adiabatically extracting all excited atoms to a supersymmetric auxiliary tweezer. The scheme works for both bosonic and fermionic atom qubits trapped in realistic Gaussian optical tweezers and may pave the way for realizing large-scale quantum computation, simulation, and information processing with neutral atoms.

光学镊子中单个中性原子的超对称辅助高保真基态制备

光镊中的中性原子量子位的阵列是用于量子计算的有前途的平台。尽管实验取得了进展，但实现中性原子量子计算的主要障碍是量子位初始化。在这里，我们提出超对称性（一种在粒子物理学中发展的理论框架）可以用于中性原子量子位的超高保真初始化。我们表明，通过绝热地将所有激发原子绝热地提取到超对称辅助镊子中，可以在光学镊子的振动基态中确定性地制备单个原子。该方案适用于现实高斯光学镊子中捕获的玻色子原子和费米子原子量子位，并且可能为实现使用中性原子的大规模量子计算，模拟和信息处理铺平道路。
