AI中文摘要：
彭宁离子阱作为量子平台，主要利用全局控制和对称狄克态进行量子模拟和传感实验。引入局部控制极大地增强了该平台作为量子模拟器的能力，但由于离子晶体的快速旋转，在技术上具有挑战性。本文使用与紫外线兼容的空间光调制器（SLM）来施加具有不同方位对称性和梯度的可编程交流斯塔克位移图案，这些图案与离子晶体共同旋转，展示了对具有100多个离子的单平面晶体的局部相干控制。将测量的离子量子比特布居与从施加的交流斯塔克位移图案的独立测量计算结果进行比较，显示出良好的一致性，验证了该技术，并为使用更高规格的SLM在彭宁阱中进行可并行、相干的单个离子寻址提供了一条途径。
英文摘要：
Penning ion traps as quantum platforms have primarily utilized global control and symmetric Dicke states for quantum simulation and sensing experiments. The introduction of local control greatly increases the power of the platform as a quantum simulator but is technically challenging due to the rapid rotation of the ion crystals. Here we use an ultraviolet-compatible spatial light modulator (SLM) to imprint programmable AC Stark shift patterns with different azimuthal symmetries and gradients that co-rotate with the ion crystals, demonstrating localized coherent control of single plane crystals with greater than 100 ions. Comparisons of the measured ion qubit populations with calculations from independent measurements of the applied AC Stark shift patterns show good agreement, validating the technique and providing a path, with a higher format SLM, for parallelizable, coherent individual ion addressing in Penning traps.
