Necessary conditions on effective quantum entanglement catalysts
Yu-Min Guo, Yi Shen, Li-Jun Zhao +4
Quantum catalytic transformations play important roles in the transformation of quantum entangled states under local operations and classical communications (LOCC). The key problem…
Inertias of entanglement witnesses
Yi Shen, Lin Chen, Li-Jun Zhao
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We study the inertias of EWs, i.e., the triplet of the numbers of negative, zero, and positiv…
Tripartite genuinely entangled states from entanglement-breaking subspaces
Yize Sun, Lin Chen
The determination of genuine entanglement is a central problem in quantum information processing. We investigate the tripartite state as the tensor product of two bipartite entangl…
Trade-off relation among genuine three-qubit nonlocalities in four-qubit systems
Li-Jun Zhao, Lin Chen, Yu-Min Guo +3
We study the trade-off relations satisfied by the genuine tripartite nonlocality in multipartite quantum systems. From the reduced three-qubit density matrices of the four-qubit ge…
Additivity of entanglement of formation via entanglement-breaking space
Li-Jun Zhao, Lin Chen
We study the entanglement-breaking (EB) space, such that the entanglement of formation (EOF) of a bipartite quantum state is additive when its range is an EB subspace. We systemati…
Constructing and unextendible product bases and positive-partial-transpose entangled states
Lin Chen, Kai Wang, Yi Shen +2
The 4-qubit unextendible product basis (UPB) has been recently studied by [Johnston, J. Phys. A: Math. Theor. 47 (2014) 424034]. From this result we show that there is only one UPB…
