论文摘要
我们提出了一种新的方案，用于单独处理被困的离子量子箱，并通过其运动频率选择它们。我们表明，几何相门可以使用自旋非依赖性和（全局）自旋依赖性力的相干干扰进行单量旋转。可以通过局部电场生成的自旋非依赖性力提高了栅极速度，同时降低了其对运动反应性的敏感性，我们在分析和数值上表现出来。尽管该方案适用于大多数被困的离子实验设置，但我们在数值上模拟了特定的无激光实现，显示出$ 10^{ - 6} $的串扰错误，以进行合理的参数。
We propose a new scheme for individual addressing of trapped ion qubits, selecting them via their motional frequency. We show that geometric phase gates can perform single-qubit rotations using the coherent interference of spin-independent and (global) spin-dependent forces. The spin-independent forces, which can be generated via localised electric fields, increase the gate speed while reducing its sensitivity to motional decoherence, which we show analytically and numerically. While the scheme applies to most trapped ion experimental setups, we numerically simulate a specific laser-free implementation, showing cross-talk errors below $10^{-6}$ for reasonable parameters.
