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…
Three-qubit pure-state canonical forms for Perfect Teleportation
Xin-Wei Zha, Hai-Yang Song
Recently, Agrawal and Pati [Phys. Rev. A 74, 062320 (2006)] have given a class of W-states that can be used for perfect teleportation. Here, two canonical forms of perfect quantum…
LU transformation invariant operators and LU transformation invariant
Xin-wei Zha, Chun-min Zhang
We proposed a concept of LU transformation invariant operators. By using this operator, arbitrary multi-qubit states LU transformation invariant and SLOCC invariant could be easily…
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…
