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…
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…
On PPT States in KxMxN Composite Quantum Systems
Xiao-Hong Wang, Shao-Ming Fei, Zhi-Xi Wang +1
We study the general representations of positive partial transpose (PPT) states in . For the PPT states with rank- a canonical…
Canonical Form and Separability of PPT States in 2xMxN Composite Quantum Systems
X. H. Wang, S. M. Fei, Z. X. Wang +1
We investigate the canonical forms of positive partial transposition (PPT) density matrices in composite quantum systems with ran…
Quantum Teleportation: from Pure to Mixed States and Standard to Optimal
S. Albeverio, S. M. Fei, W. L. Yang
Teleportation for pure states, mixed states with standard and optimal protocols are introduced and investigated systematically. An explicit equation governing the teleportation of…
Separability of rank two quantum states on multiple quantum spaces with different dimensions
Shao-Ming Fei, Xiu-Hong Gao, Xiao-Hong Wang +2
We consider the separability of rank two quantum states on multiple quantum spaces with different dimensions. The sufficient and necessary conditions for separability of these mult…
