摘要
我们在场与穿过一些相同原子在被套住的一个光洞的一个二水平的原子实现一扇 one-qubit 阶段门的一个计划。一个人能方便地由适当地选择在洞和穿过洞的原子的速度套住的原子的数字获得门的任意的阶段移动。现在的计划为实现 one-qubit 阶段门提供一个很简单、有效的方法。
We present a scheme to implement a one-qubit phase gate with a two-level atom crossing an optical cavity in which some identical atoms are trapped. One can conveniently acquire an arbitrary phase shift of the gate by properly choosing the number of atoms trapped in the cavity and the velocity of the atom crossing the cavity. The present scheme provides a very simple and efficient way for implementing one-qubit phase gate.
