Quantum Wasserstein distance between unitary operations
Xinyu Qiu, Lin Chen
Quantifying the effect of noise on unitary operations is an essential task in quantum information processing. We propose the quantum Wasserstein distance between unitary operations…
Coherence and entanglement in Grover and Harrow-Hassidim-Lloyd algorithm
Changchun Feng, Lin Chen, Lijun Zhao
Coherence, discord and geometric measure of entanglement are important tools for measuring physical resources. We compute them at every steps of the Grover's algorithm. We summariz…
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…
One-way quantum deficit and quantum coherence in the anisotropic chain
Biao-Liang Ye, Bo Li, Li-Jun Zhao +2
In this study, we investigate pairwise non-classical correlations measured using a one-way quantum deficit as well as quantum coherence in the spin-1/2 chain in a transverse m…
