摘要:

我们报告的多区线性RF保罗陷阱,利用退化硅的可加工性和导电性的制造技术。该方法进行了测试,通过捕获和激光冷却24 Mg+离子在两个陷阱的几何形状:一个单区两层陷阱和一个多区表面电极陷阱。根据测得的离子运动加热速率,我们确定当离子位于阱表面上方40微米处时,在1.125 MHz的频率下,离子位置处的电场谱密度约为1 E-10(V/m)^2/Hz。这些设备的一个应用是原子离子量子比特的受控操纵,这是量子信息处理的一种形式的基础。

英文摘要:

We report techniques for the fabrication of multi-zone linear RF Paul traps that exploit the machinability and electrical conductivity of degenerate silicon. The approach was tested by trapping and laser cooling 24Mg+ ions in two trap geometries: a single-zone two-layer trap and a multi-zone surface-electrode trap. From the measured ion motional heating rate we determine an electric field spectral density at the ion's position of approximately 1E-10 (V/m)^2/Hz at a frequency of 1.125 MHz when the ion lies 40 micron above the trap surface. One application of these devices is controlled manipulation of atomic ion qubits, the basis of one form of quantum information processing.
