| 摘 要： | 提出了一个实现两离子量子逻辑门的简单方案。本方案使用了两个囚禁于线性阱的三能级离子。本方案不使用振动模作为数据总线,仅需要激光与离子的单个相互作用,因而相互作用时间变短,这点从退相干的角度看是很重要的,而且本方案对振动模的加热不敏感。

| Abstract: | In the system with two three-level ions confined in a linear trap,a simple scheme is presented for realizing a two-ion quantum logic gate.The scheme does not use the vibrational mode as the data bus but only requires a single interaction of the ions with the lasers.Thus the interaction time comes very short,which is important in view of decoherence.Furthermore,the scheme is insensitive to the heating of vibrational motion. |
