A scheme is proposed for fast generation of entangled states in directly coupled bimodal-mode cavities based on shortcuts to adiabatic passage. The scheme can be realized by transitionless quantum driving with the help of quantum Zeno dynamics and non-resonant lasers. First, we simplify the system by the quantum Zeno dynamics. Then, under the large detuning condition, we get the effective Hamiltonian which is equivalent to the corresponding counter-diabatic driving Hamiltonian to speed up the evolution process. The effects of decoherence induced by atomic spontaneous emission, leakage of the cavity and operational imperfection are also taken into account. The numerical simulation result shows that this scheme is robust against these factors. During realizing the scheme, the laser pulses are not strongly limited and the auxiliary levels or multi-step operations are not needed. Moreover, for any quantum system whose Hamiltonian is possible to be simplified into the same form in the paper, the corresponding alternative physically feasible Hamiltonian can be built with present method, which provides a scalable way for the preparation of entangled states in theory.

在直接耦合双峰模式 Cavitiesseee 中快速生成纠缠态的绝热通道捷径

提出了一种基于绝热通道捷径的直接耦合双峰模腔中纠缠态的快速生成方案。该方案可以在量子芝诺动力学和非谐振激光器的帮助下通过无跃迁量子驱动来实现。首先，我们通过量子芝诺动力学来简化系统。然后，在大失谐条件下，我们得到有效哈密顿量，相当于相应的反非绝热驱动哈密顿量，以加快演化过程。还考虑了由原子自发发射、腔泄漏和操作缺陷引起的退相干效应。数值模拟结果表明，该方案对这些因素具有鲁棒性。在实现方案的过程中，激光脉冲不受强限制，不需要辅助电平或多步操作。此外，对于任何一个量子系统，其哈密顿量可以简化为本文中相同的形式，相应的替代物理上可行的哈密顿量可以用现有方法构建，这为理论上的纠缠态的制备提供了一种可扩展的方式。
