Z. Y. Xu, W. L. Yang, M. Feng

摘要:

非马尔可夫性是最近提出的对开放量子系统中非马尔可夫行为的一种描述,基于此,我们首先提出了一种直接测量耦合到零温玻色子库的单个量子比特的非马尔可夫特性的实用思想,然后扩展到研究两个非相互作用的量子比特分别受两个库约束的动力学行为,并给出了非马尔可夫性的下界.我们的方案不需要优化过程和量子态层析,有利于实验实现。

英文摘要:

The non-Markovianity is a recently proposed characterization of the non-Markovian behavior in an open quantum system, based on which we first present a practical idea for directly measuring the non-Markovian character of a single qubit coupled to a zero-temperature bosonic reservoir, and then extend to investigate the dynamics of two noninteracting qubits subject to two reservoirs respectively with a lower bound of non-Markovianity. Our scheme, with no need of optimization procedures and quantum state tomography, is helpful for experimental implementation.
