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…
Quantum dynamics of double-qubits in a spin star lattice with an XY interaction
Jun Jing, Zhi-Guo Lü
The dynamics of two coupled spins-1/2 interacting with a spin-bath via the quantum Heisenberg XY coupling is studied. The pair of central spins served as a quantum open subsystem a…
Level crossing and quantum phase transition of the XY model
Jun Jing, H. R. Ma
The ground state of a one-dimensional spin-1/2 chain with periodical boundary condition in the Heisenberg XY model is investigated. We consider the spatial correlation and concurre…
