Non-local dynamics of Bell states in separate cavities
Jun Jing, Zhi-guo Lü, Guo-hong Yang
We present non-local dynamics of Bell states in separate cavities. It is demonstrated that (i) the entanglement damping speed will saturate when the cavity leakage rate …

Controllable dynamics of two separate qubits in Bell states
Jun Jing, Zhi-guo Lü, Guo-hong Yang
The dynamics of entanglement and fidelity for a subsystem of two separate spin-1/2 qubits prepared in Bell states is investigated. One of the subsystem qubit labelled is under…

Physical mechanism of superluminal traversal time: interference between multiple finite wave packets
Xi Chen, Chun-Fang Li
The mechanism of superluminal traversal time through a potential well or potential barrier is investigated from the viewpoint of interference between multiple finite wave packets,…
