论文摘要
我们开发了在腔 - QED网络中有效光子传输的最佳协议。这是通过刺激的拉曼绝热通道（Stirap）方案执行的，其中随时间变化的电容耦合（经过精心选择的扫描速率）起着关键作用。我们在半经典限制有效的制度中工作，并研究了由光结合耦合引起的动力混乱。我们表明，这对于确保有效的光子传递的扫描速率估算较低限制起着至关重要的作用。我们介绍模型的Hermitian以及开放量子系统的扩展。在不失去一般性的情况下，我们研究了三个空腔和四个腔体病例，我们的结果可以适应更大的网络。我们的分析对于设计针对非线性开放量子系统的运输协议也很重要。
We develop optimal protocols for efficient photon transfer in a cavity-QED network. This is executed through stimulated Raman adiabatic passage (STIRAP) scheme, where time-varying capacitive couplings (with carefully chosen sweep rate) play a key role. We work in a regime where semiclassical limit is valid and we investigate the dynamical chaos caused by the light-matter coupling. We show that this plays a crucial role in estimating the lower bound on the sweep rate for ensuring efficient photon transfer. We present Hermitian as well as an open quantum system extension of the model. Without loss of generality, we study the three cavity and four cavity case and our results can be adapted to larger networks. Our analysis is also significant in designing transport protocols aimed for nonlinear open quantum systems in general.
