A hierarchy of entanglement criteria for four qubit symmetric Greenberger-Horne-Zeilinger diagonal states
Xiao-yu Chen, Li-zhen Jiang
With a two step optimization method of entanglement witness, we analytically propose a set of necessary and sufficient entanglement criteria for four qubit symmetric Greenberger-Ho…
Precise detection of multipartite entanglement in four-qubit Greenberger--Horne--Zeilinger diagonal states
Xiao-yu Chen, Li-zhen Jiang, Zhu-an Xu
We propose a method of constructing the separability criteria for multipartite quantum states on the basis of entanglement witnesses. The entanglement witnesses are obtained by fin…
Necessary and sufficient criterion for k-separability of N-qubit noisy GHZ states
Xiao-yu Chen, Li-zhen Jiang, Zhu-an Xu
A Multipartite entangled state has many different kinds of entanglement specified by the number of partitions. The most essential example of multipartite entanglement is the entang…
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…
