Entanglement and quantum phase transition in quantum mixed spin chains
Shang-Bin Li, Zhao-Xing Xu, Jian-Hui Dai +1
The ground entanglement and thermal entanglement in quantum mixed spin chains consisting of two integer spins 1 and two half integer spins 1/2 arrayed as in a uni…
Maximally entangled mixed states of two atoms trapped inside an optical cavity
Shang-Bin Li, Jing-Bo Xu
In some off-resonant cases, the reduced density matrix of two atoms symmetrically coupled with an optical cavity can very approximately approach to maximally entangled mixed states…
Influence of intrinsic decoherence on nonclassical properties of the output of a Bose-Einstein condensate
Shang-Bin Li, Jing-Bo Xu
We investigate nonclassical properties of the output of a Bose-Einstein condensate in Milburn's model of intrinsic decoherence. It is shown that the squeezing property of the atom…
Entanglement of pair cat states and teleportation
Shang-Bin Li, Ru-Kuan Wu, Qin-Mei Wang +1
The entanglement of pair cat states in the phase damping channel is studied by employing the relative entropy of entanglement. It is shown that the pair cat states can always be di…
Quantum control of entanglement and information of two solid state qubits: remote control of dephasing
Shang-Bin Li, Jing-Bo Xu
We investigate the scheme for controlling information characterized by Von-Neumann entropy and the stationary state entanglement characterized by concurrence of two solid state qub…
Stationary entanglement and nonlocality of two qubits or qutrits collectively interacting with the thermal environment: The role of Bell singlet state
Shang-Bin Li, Jing-Bo Xu
We investigate the stationary entanglement and stationary nonlocality of two qubits collectively interacting with a common thermal environment. We assume two qubits are initially i…
