Realignment Entanglement Criterion for Continuous Bipartite Symmetric Quantum States
Xiao-yu Chen, Li-zhen Jiang, Ping Yu +1
The separability of bipartite non-Gaussian states is studied by applying the realignment criterion with the technique of functional analysis. The realignment criterion is given as…

Genuine Entanglement of Four Qubit Cluster Diagonal States
Xiao-yu Chen, Ping Yu, Li-zhen Jiang +1
We reduce the necessary and sufficient biseparable conditions of the four qubit cluster diagonal state to concise forms. Only 4 out of the 15 parameters are proved to be relevant i…

Entanglement and genuine entanglement of three qubit GHZ diagonal states
Xiao-yu Chen, Li-zhen Jiang, Ping Yu +1
We analytically prove the necessary and sufficient criterion for the full separability of three-qubit Greenberger-Horne-Zeilinger (GHZ) diagonal states. The corresponding entanglem…
