Evolution equation of entanglement for general bipartite systems
Zong-Guo Li, S. M. Fei, Z. D. Wang +1
We explore how entanglement of a general bipartite system evolves when one subsystem undergoes the action of an arbitrary noisy channel. It is found that the dynamics of entangleme…

An Ideal Channel of Long Distance Entanglement in Spin Systems
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using spin chain to realize an ideal channel of long distance entanglement. The results show that there has different entanglement in different Hilbert subs…

Designing a Spin Channel for Perfect Quantum Communication
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using a spin chain with fixed symmetry interaction as a channel for perfect quantum communication. The perfect quantum communication is determined by the ei…
