论文摘要
我们通过同时应用电场和旋转依赖性梯度，提出了一种在多区域陷阱的单独相互作用区域中相干控制离子量子位的新方法。有效的单品旋转的相位和幅度都取决于电场，这可以定位于每个区域。我们使用表面电离离子陷阱中的激光基和磁场梯度在单个离子上证明了这种相互作用，并测量电场的定位。
We present a new method for coherent control of trapped ion qubits in separate interaction regions of a multi-zone trap by simultaneously applying an electric field and a spin-dependent gradient. Both the phase and amplitude of the effective single-qubit rotation depend on the electric field, which can be localised to each zone. We demonstrate this interaction on a single ion using both laser-based and magnetic field gradients in a surface-electrode ion trap, and measure the localisation of the electric field.
