由于量子位参数的快速调制,在电路QED中观察动态和反动态卡西米尔效应的前景

Prospects for observing dynamical and anti- dynamical Casimir effects in circuit QED due to fast modulation of qubit parameters

D. S. Veloso, A. V. Dodonov

摘要:

我们考虑了非稳态电路QED体系结构,其中单个人工二能级原子在一个或多个系统参数的外部调制下与腔场模相互作用。采用两种不同的方法研究了马尔可夫耗散对原子-光场缀饰态之间调制诱导跃迁的影响:量子光学标准主方程和最近提出的缀饰图像主方程。我们估计相关的跃迁速率,并表明,光子产生真空(“动态卡西米尔效应”,DCE)和相干光子湮灭从非真空状态(“反DCE”)是可能的与当前国家的最先进的参数。

英文摘要:

We consider the nonstationary circuit QED architecture, where a single artificial two-level atom interacts with a cavity field mode under external modulation of one or more system parameters. Two different approaches are employed to study the effects of Markovian dissipation on modulation-induced transitions between the atom-field dressed states: the standard master equation of Quantum Optics and the recently formulated dressed-picture master equation. We estimate the associated transition rates and show that photon generation from vacuum ("dynamical Casimir effect", DCE) and coherent photon annihilation from nonvacuum states ("Anti-DCE") are possible with the current state-of-the-art parameters.
