摘要:

微制造阱中的离子密集阵列代表了一种可能的方法来按比例放大离子阱量子计算。寻址单个离子的能力是这种方案的重要组成部分。我们证明了个体寻址的被困离子在一个微制造的表面电极陷阱,使用芯片上产生的磁场梯度。对于相隔5 μ m的两个离子,实现了310(2)kHz的频率分裂。选择性单量子位操作在两个捕获离子之一上进行,平均串扰为2.2+/-1.0%。通过自旋回波技术测量的相干时间不受场梯度的影响。

英文摘要:

Dense array of ions in microfabricated traps represent one possible way to scale up ion trap quantum computing. The ability to address individual ions is an important component of such a scheme. We demonstrate individual addressing of trapped ions in a microfabricated surface-electrode trap using a magnetic field gradient generated on-chip. A frequency splitting of 310(2) kHz for two ions separated by 5 um is achieved. Selective single qubit operations are performed on one of two trapped ions with an average of 2.2+/-1.0% crosstalk. Coherence time as measured by the spin-echo technique is unaffected by the field gradient.
