腔-QED网络中混沌的产生和受控光子传输

Emergence of chaos and controlled photon transfer in a cavity-QED network

Amit Dey, Manas Kulkarni

摘要:

我们开发了一个腔QED网络中的有效的光子传输的最佳协议。这是通过受激拉曼绝热通道(STIRAP)方案执行的,其中时变电容耦合(具有精心选择的扫描速率)起着关键作用。我们在半经典极限有效的情况下工作,研究了光-物质耦合引起的动力学混沌。我们表明,这起着至关重要的作用,估计扫描速率的下限,以确保有效的光子传输。我们提出了厄米以及一个开放量子系统扩展的模型。不失一般性,我们研究了三腔和四腔的情况下,我们的结果可以适用于更大的网络。我们的分析对于一般非线性开放量子系统的传输协议的设计也是有意义的。

英文摘要:

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.
