Enhancement of non-equilibrium thermal quantum discord and entanglement of a three-spin XX chain by multi-spin interaction and external magnetic field
Xiu-xing Zhang, Fu-li Li
We investigate the non-equilibrium thermal quantum discord and entanglement of a three-spin chain whose two end spins are respectively coupled to two thermal reservoirs at differen…

Controlling transfer of quantum correlations among bi-partitions of a composite quantum system by combining noisy environments
Xiu-xing Zhang, Fu-li Li
The correlation dynamics is investigated for various bi-partitions of a composite system consisting of two qubits, and two independent and non-identical noisy environments. The two…
