摘要

我们讨论了如何通过考虑由强微波场驱动的两能级原子与m+1腔模式的连续相互作用来实现量子逻辑门。该方案对原子的初始状态不敏感,并且操作时间与系统操作中涉及的腔模式的数量无关。该方案在短于光子寿命的时间内实现了两个量子逻辑门(m-目标量子位控制的全局相位门和多量子位相移门)。我们还研究了退相干对保真度的影响。总的来说,我们的系统对光子和原子衰变率的敏感性较低,因此可以通过实验实现。

Dynamics of one two-level-atom interacting with a multiple cavity modes
We discuss how to implement quantum logic gates by considering a two-level-atom driven by a strong microwave field and successively interacting with m+1 cavity modes. The scheme is insensitive to the initial state of the atom, and the operation time is independent of the number of cavity modes involved in the system operations. This scheme is used to realize two quantum logic gates (m-target-qubit controlled-global-phase gate and Multi-qubit phase shift gate) in a time much shorter than the photonic lifetime. We also studied the influence of decoherence on the fidelity. In general, our system is reasonably less sensitive to the photonic and atomic decay rates and therefore it can be experimentally realized.
