Tropical contraction of tensor networks as a Bell inequality optimization toolset
Mengyao Hu, Jordi Tura
We show that finding the classical bound of broad families of Bell inequalities can be naturally framed as the contraction of an associated tensor network, but in tropical algebra,…
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…
-reducible matrices in six-dimensional mutually unbiased bases
Xiaoyu Chen, Mengfan Liang, Mengyao Hu +1
Finding four six-dimensional mutually unbiased bases (MUBs) containing the identity matrix is a long-standing open problem in quantum information. We show that if they exist, then…
Strong quantum nonlocality from hypercubes
Fei Shi, Mao-Sheng Li, Mengyao Hu +4
A set of multipartite orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition. Most known constructions of strongly nonlocal orthogonal pro…
Unextendible product operator basis
Mengyao Hu, Lin Chen, Fei Shi +2
Quantum nonlocality is associated with the local indistinguishability of orthogonal states. Unextendible product basis (UPB), a widely used tool in quantum information, exhibits no…
A complete picture of the four-party linear inequalities in terms of the 0-entropy
Zhiwei Song, Lin Chen, Yize Sun +1
Multipartite quantum system is complex. Characterizing the relations among the three bipartite reduced density operators , and of a tripartite state $ρ_{A…
Genuine entanglement, distillability and quantum information masking under noise
Mengyao Hu, Lin Chen
Genuineness and distillability of entanglement play a key role in quantum information tasks, and they are easily disturbed by the noise. We construct a family of multipartite state…
Strongly nonlocal unextendible product bases do exist
Fei Shi, Mao-Sheng Li, Mengyao Hu +4
A set of multipartite orthogonal product states is locally irreducible, if it is not possible to eliminate one or more states from the set by orthogonality-preserving local measure…
Strong quantum nonlocality with entanglement
Fei Shi, Mengyao Hu, Lin Chen +1
Strong quantum nonlocality was introduced recently as a stronger manifestation of nonlocality in multipartite systems through the notion of local irreducibility in all bipartitions…
Constructing three-qubit unitary gates in terms of Schmidt rank and CNOT gates
Zhiwei Song, Lin Chen, Mengyao Hu
It is known that every two-qubit unitary operation has Schmidt rank one, two or four, and the construction of three-qubit unitary gates in terms of Schmidt rank remains an open pro…
Mutually unbiased bases containing a complex Hadamard matrix of Schmidt rank three
Mengyao Hu, Yize Sun, Lin Chen
Constructing four six-dimensional mutually unbiased bases (MUBs) is an open problem in quantum physics and measurement. We investigate the existence of four MUBs including the iden…
Real Entries of Complex Hadamard Matrices and Mutually Unbiased Bases in Dimension Six
Mengfan Liang, Mengyao Hu, Yize Sun +1
We investigate the number of real entries of an complex Hadamard matrix (CHM). We analytically derive the numbers when . In particular, the number can be any…
Multi-linear Monogamy Relations for Three Qubit States
Xian Shi, Lin Chen, Mengyao Hu
The monogamy of entanglement means that entanglement cannot be freely shared. In 2014, Oliveira et al. [ Oliveira et al., Phys. Rev. A. 89, 034303 (2014)] proposed a monogamy relat…
