Concurrence of arbitrary dimensional bipartite quantum states
Kai Chen, Sergio Albeverio, Shao-Ming Fei
We derive an analytical lower bound for the concurrence of a bipartite quantum state in arbitrary dimension. A functional relation is established relating concurrence, the Peres-Ho…
Finite isometry groups of 4-manifolds with positive sectional curvature
Fuquan Fang
Let M be an oriented compact positively curved 4-manifold. Let G be a finite subgroup of the isometry group of . Among others, we prove that there is a universal constant C (cf.…
Canonical Form and Separability of PPT States on Multiple Quantum Spaces
Xiao-Hong Wang, Shao-Ming Fei
By using the "subtracting projectors" method in proving the separability of PPT states on multiple quantum spaces, we derive a canonical form of PPT states in ${\Cb}^{K_1} \otimes…
Quantum secret sharing between multi-party and multi-party without entanglement
Feng-Li Yan, Ting Gao
We propose a quantum secret sharing protocol between multi-party ( members in group 1) and multi-party ( members in group 2) using a sequence of single photons. These single…
