Role of initial system-bath correlation on coherence trapping
Ying-Jie Zhang, Wei Han, Yun-Jie Xia +2
We study the coherence trapping of a qubit correlated initially with a non-Markovian bath in a pure dephasing channel. By considering the initial qubit-bath correlation and the bat…
Classical-driving-assisted quantum speed-up
Ying-Jie Zhang, Wei Han, Yun-Jie Xia +2
We propose a method of accelerating the speed of evolution of an open system by an external classical driving field for a qubit in a zero-temperature structured reservoir. It is sh…
Quantum speed limits for Bell-diagonal states
Ying-Jie Zhang, Wei Han, Yun-Jie Xia +3
Bounds of the minimum evolution time between two distinguishable states of a system can help to assess the maximal speed of quantum computers and communication channels. We study t…
Quantum speed limit for arbitrary initial states
Yingjie Zhang, Wei Han, Yunjie Xia +2
We investigate the generic bound on the minimal evolution time of the open dynamical quantum system. This quantum speed limit time is applicable to both mixed and pure initial stat…
Enhancing entanglement trapping by weak measurement and quantum measurement reversal
Ying-Jie Zhang, Wei Han, Heng Fan +1
In this paper, we propose a scheme to enhance trapping of entanglement of two qubits in the environment of a photonic band gap material. Our entanglement trapping promotion scheme…
Quantum correlations dynamics under different non-markovian environmental models
Ying-Jie Zhang, Wei Han, Chuan-Jia Shan +1
We investigate the roles of different environmental models on quantum correlation dynamics of two-qubit composite system interacting with two independent environments. The most com…
