论文摘要
在本文中，我们研究了在重复测量中与两个独立储层相互作用的量子系统会发生什么。特别是，我们研究了与谐波振荡器组成的储层相互作用的两级系统的行为。与一个储层的相互作用与耗散型耦合相互作用，而与另一个储层的相互作用则与型型耦合相互作用。使用极化子变换，我们表明，由于弱耦合储层的影响，强耦合储层的存在实际上可以降低量子系统的衰减速率。
In this paper, we look into what happens to a quantum system under repeated measurements if it interacts with two independent reservoirs. In particular, we look at the behavior of a two-level system interacting with reservoirs consisting of harmonic oscillators. The interaction with one reservoir is weak with a dissipative-type coupling, while the interaction with the other reservoir is strong with a dephasing-type coupling. Using a polaron transformation, we show that the presence of the strongly coupled reservoir can actually reduce the decay rate of the quantum system due to the effect of the weakly-coupled reservoir.
