标题： Plane-selective manipulations of nuclear spin qubits in a three-dimensional optical tweezer array

摘要： 一个实用容错量子计算机的核心挑战之一是可扩展性。 光学镊子阵列的三维结构为扩展中性原子处理器提供了潜力。 然而，对于量子纠错至关重要的相干局部操作，尚未在此平台上进行探索。 在这里，我们展示了在三维原子阵列中对${}^{171}\mathrm{Yb}$原子的核自旋量子比特逐层初始化，以及量子比特的层依赖相干时间演化，同时还通过将原子从${}^1S_0$状态激发到${}^3P_2$状态实现了层选择性的量子比特操控。 这种层选择性操控技术为在三维多层架构中进行量子计算和量子模拟铺平了道路。 显示英文摘要

摘要： One of the central challenges for a practical fault-tolerant quantum computer is scalability. A three-dimensional structure of optical tweezer arrays offers the potential for scaling up neutral atom processors. However, coherent local operations, essential for quantum error correction, have yet to be explored for this platform. Here, we demonstrate plane-by-plane initialization of nuclear spin qubits of ${}^{171}\mathrm{Yb}$ atoms in a three-dimensional atom array and plane-dependent coherent temporal evolution of qubits, as well as plane-selective qubit manipulation by exploiting the plane-selective excitation of the atoms from the ${}^1S_0$ to the ${}^3P_2$ state. This plane-selective manipulation technique paves the way for quantum computing and quantum simulation in three-dimensional multilayer architectures.
