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…
Entanglement Criterion for Coherent Subtraction and Coherent Addition Bipartite Continuous variable States
Li-zhen Jiang, Xiao-yu Chen, Tian-yu Ye +1
Photon subtraction and addition are experimental means of generating non-Gaussian states from Gaussian states. Coherent subtraction or addition is a combination of photon subtracti…
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…
