Comment on: Stochastic local operations and classical communication Invariant and the residual entanglement for n qubits
XinWei Zha, HaiYang Song, MingLiang Hu
In a recent paper [Phys. Rev. A 76, 032304(2007)], Li et al. proposed the definition of the residual entanglement for n qubits by means of the Stochastic local operations and class…

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…

Non-EPR pairs quantum channel for teleporting an arbitrary two-qubit state
Xin-Wei Zha, Hai-Yang Song
Recently, Yeo and Chua [Phys. have given an explicit protocol for faithfully teleporting an arbitrary two-qubit state via a genuine four-qubit entangled state, which is not reducib…
