Inertia of partial transpose of positive semidefinite matrices
Yixuan Liang, Jiahao Yan, Dongran Si +1
We show that the partial transpose of positive semidefinite matrices do not have inertia (4,1,4) and (3,2,4). It solves an open problem in "LINEAR AND MULTILINEAR ALGEB…

Nonlocality via multiqubit orthogonal product bases
Lin Chen, Yutong Jiang
We investigate the quantum nonlocality via the discrimination on two, three and four-qubit orthogonal product bases (OPBs). We show that every two-qubit, and some three and four-qu…
