论文摘要
被困的离子拥有较长的连贯时间和出色的门忠诚度，使其成为量子信息处理的有用平台。在RF Paul陷阱中扩展到大量的离子Qubers需要巨大的努力。捕获离子的另一种技术是通过一个笔记陷阱，其中通过在存在强磁场的情况下控制离子的旋转来形成数百个离子的2D晶体。但是，离子晶体的旋转使单个离子可寻址性成为一个重大挑战。我们提出了一种利用可变形镜的协议，以引入晶体旋转框架中静态的交流恒星移位模式。通过数值模拟，我们验证了该方案在数百个离子的晶体阵列中执行高保真单离子门的潜力。
Trapped ions boast long coherence times and excellent gate fidelities, making them a useful platform for quantum information processing. Scaling to larger numbers of ion qubits in RF Paul traps demands great effort. Another technique for trapping ions is via a Penning trap where a 2D crystal of hundreds of ions is formed by controlling the rotation of the ions in the presence of a strong magnetic field. However, the rotation of the ion crystal makes single ion addressability a significant challenge. We propose a protocol that takes advantage of a deformable mirror to introduce AC Stark shift patterns that are static in the rotating frame of the crystal. Through numerical simulations we validate the potential of this protocol to perform high-fidelity single-ion gates in crystalline arrays of hundreds of ions.
