Quantumness protection for open systems in a double-layer environment
Yu-Long Qiao, Jia-Ming Zhang, Yusui Chen +2
We study the dynamics of the two-level atomic systems (qubits) under a double-layer environment that is consisted of a network of single-mode cavities coupled to a common reservoir…
Exact coherence dynamics mediated by a single cavity mode in the presence of leakage
Yusui Chen, Quanzhen Ding, Wufu Shi +2
We present a quantum-state-diffusion equation to characterize the dynamics of a generic atomic system coupled to a leaky cavity mode. As quantum resources, the population, the cohe…
Exact non-Markovian master equations for multiple qubit systems: quantum trajectory approach
Yusui Chen, J. Q. You, Ting Yu
A wide class of exact master equations for a multiple qubit system can be explicitly constructed by using the corresponding exact non-Markovian quantum state diffusion equations. T…
Crossover Between Non-Markovian and Markovian Dynamics Induced by a Hierarchical Environment
Tiantian Ma, Yusui Chen, Tian Chen +2
Non-Markovian evolution of an open quantum system can be induced by the memory effects of a reservoir. Although a reservoir with stronger memory effects may seem like it should cau…
