Operator representations for a class of quantum entanglement measures and criterions
Z. Xu, B. Zeng, D. L. Zhou
We find that a class of entanglement measures for bipartite pure state can be expressed by the average values of quantum operators, which are related to any complete basis of one p…
A criterion for testing multi-particle NPT entanglement
B. Zeng, D. L. Zhou, P. Zhang +2
We revisit the criterion of multi-particle entanglement based on the overlaps of a given quantum state with maximally entangled states. For a system of particles, each with…
Quantum teleportation using cluster states
B. Zeng, D. L. Zhou, Z. Xu +1
A protocol of quantum communication is proposed in terms of the multi-qubit quantum teleportation through cluster states (Phys. Rev. Lett. \textbf{86}, 910 (2001)). Extending the c…

General Schemes for multi-particle d-dimensional Cat-like State Teleportation
Bei Zeng, Xiao Shu Liu, Yan Song Li +1
Two kinds of -particle d-dimensional cat-like state teleportation protocols are present. In the first protocol, the teleportation is achieved by d-dimensional Bell-basis measure…
