论文摘要
最近目睹了量子技术的显着进步。鉴于此,重要的是将开放量子系统作为此类量子设备的模型进行研究。量子设备通常需要极端条件,例如设备操作的温度非常低。在这种情况下,与高温制度中的马尔可夫动力学相反,动力学可能是非马克维亚人。这种观察结果使我们必须在理论上和实验上研究非马克维亚开放量子系统。在本文中,我们报告了两个重要的结果:1)简单但非平淡的理论模型的精确解决方案,以及2)通过NMR实验证明该模型,其中非马克维亚性是可以连续控制的。我们观察到理论与实验之间的定性一致性。
Recently remarkable progress in quantum technology has been witnessed. In view of this it is important to investigate an open quantum system as a model of such quantum devices. Quantum devices often require extreme conditions such as very low temperature for the devices to operate. Dynamics can be non-Markovian in such a situation in contrast with Markovian dynamics in high temperature regime. This observation necessitates us to investigate a non-Markovian open quantum system, both theoretically and experimentally. In this paper, we report two important results: 1) Exact solution of a simple but non-trivial theoretical model and 2) demonstration of this model by NMR experiments, where non-Markovianity is continuously controllable. We observe qualitative agreement between theory and experiment.
