The classical capacity for the quantum Markov channel of continuous variables
Tao Qin, Meisheng Zhao, Yongde Zhang
Quantum communications using continuous variables are quite mature experimental techniques and the relevant theories have been extensively investigated with various methods. In thi…
Collapse of the Entangled State and the Entropy Increase in an Isolated System
Qi-Ren Zhang
We show that the collapse of the entangled quantum state makes the entropy increase in an isolated system. The second law of thermodynamics is thus proven in its most general form.
Convergent Iterative Solutions for a Sombrero-Shaped Potential in Any Space Dimension and Arbitrary Angular Momentum
R. Friedberg, T. D. Lee, W. Q. Zhao
We present an explicit convergent iterative solution for the lowest energy state of the Schroedinger equation with an -dimensional radial potential an…

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…
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…
