We present a new method of spin-motion coupling for trapped ions using microwaves and a magnetic field gradient oscillating close to the ions' motional frequency. We demonstrate and characterize this coupling experimentally using a single ion in a surface-electrode trap that incorporates current-carrying electrodes to generate the microwave field and the oscillating magnetic field gradient. Using this method, we perform resolved-sideband cooling of a single motional mode to its ground state.
我们提出了一种用于捕获离子的自旋 - 运动耦合新方法，该方法利用微波和一个在接近离子运动频率处振荡的磁场梯度。我们在一个表面电极阱中使用单个离子，通过实验演示并表征了这种耦合，该表面电极阱包含载流电极以产生微波场和振荡磁场梯度。利用这种方法，我们将单个运动模式冷却到其基态的分辨边带冷却状态。
