In this paper, we present the generation of a CNOT gate between two atoms in a cavity based on transitionless quantum driving. Compared to some previous schemes, the proposed scheme for generating a CNOT gate significantly shortens the duration time. Besides, the scheme is insensitive to the fluctuation of evolution time and coupling coefficient. Also, the influences of atomic spontaneous emission and cavity decay on the fidelity are discussed by numerical simulation. The numerical result shows that the scheme is robust against decoherence.

通过无跃迁量子驱动快速而稳健地生成 CNOT 门

在本文中，我们介绍了基于无跃迁量子驱动在腔中的两个原子之间生成 CNOT 门。与之前的一些方案相比，所提出的生成 CNOT 门的方案显着缩短了持续时间。此外，该方案对演化时间和耦合系数的波动不敏感。此外，通过数值模拟讨论了原子自发发射和腔衰变对保真度的影响。数值结果表明该方案对退相干具有鲁棒性。
