发布时间：2018-10-10 06:27
【摘要】：基于绝热捷径技术,我们提出了一个通过设计共振脉冲,仅用一个操作步骤便实现两原子相位门的理论方案。我们讨论了原子自发辐射和腔中光子泄漏对方案的影响,数值结果表明当前方案对上面的两种耗散效应和试验参数的误差都具有鲁棒性。此外,本方案所需的演化时间非常短并且在整个演化过程中都不需要额外引入复杂的脉冲。因此,这个方案在当前实验条件下是比较容易实现的。
[Abstract]:Based on the adiabatic shortcut technique, we propose a theoretical scheme for the realization of two atomic phase gates by designing resonance pulses and using only one operation step. The effects of atomic spontaneous emission and photon leakage in cavity on the scheme are discussed. The numerical results show that the current scheme is robust to the above two dissipative effects and the errors of experimental parameters. In addition, the evolution time of the scheme is very short and complex pulses are not needed in the whole evolution process. Therefore, this scheme is relatively easy to implement under the current experimental conditions.
