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 labeled A is under the influence of a… (More)

The dynamics of two $1∕2$-spin qubits under the influence of a quantum Heisenberg $XY$-type spin-bath is studied. After the Holstein-Primakoff transformation, numerical polynomial scheme is used to… (More)

The dynamics of two spins-1/2 interacting with a spin-bath via the quantum Heisenberg x–y coupling is studied. The purity, z-component summation and the concurrence of the central subsystem are… (More)
It is well established that an entanglement encoded in the Bell states of a two-qubit system with correlated spins exhibits completely different evolution properties from that encoded in states with… (More)

Abstract 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 γ ⩾ 0.4 ; (ii) the… (More)

The time evolution of entanglement for excitons in two quantum dots embedded in a single mode cavity is studied in a ``spin-boson'' regime. It is found that although with the dissipation from the… (More)
