论文摘要
量子Kerr-Noninlinear振荡器是腔和量子电动力学和量子验光力学中的范式模型。从理论上讲,我们在一个冲动激发(“踢”)Kerr-Nonlinearearearearearearearearearearear振荡器中研究回声现象。我们揭示了两种类型的回声:“量子”和“古典”,分别出现在长时间和短时间上。讨论了回声的机制,并考虑了它们对耗散的敏感性。这些回声可能可用于研究与量子信息处理相关的许多系统中的分解过程。
Quantum Kerr-nonlinear oscillator is a paradigmatic model in cavity and circuit quantum electrodynamics, and quantum optomechanics. We theoretically study the echo phenomenon in a single impulsively excited ("kicked") Kerr-nonlinear oscillator. We reveal two types of echoes, "quantum" and "classical" ones, emerging on the long and short time-scales, respectively. The mechanisms of the echoes are discussed, and their sensitivity to dissipation is considered. These echoes may be useful for studying decoherence processes in a number of systems related to quantum information processing.
