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…
Quantum secure direct communication by Einstein-Podolsky-Rosen pairs and entanglement swapping
Ting Gao, Feng-Li Yan, Zhi-Xi Wang
We present a quantum secure direct communication scheme achieved by swapping quantum entanglement. In this scheme a set of ordered Einstein-Podolsky-Rosen (EPR) pairs is used as a…
Deterministic secure direct communication using GHZ states and swapping quantum entanglement
Ting Gao, Feng-Li Yan, Zhi-Xi Wang
We present a deterministic secure direct communication scheme via entanglement swapping, where a set of ordered maximally entangled three-particle states (GHZ states), initially sh…
Quantum Logic Networks for Probabilistic Teleportation of Many Particle State of General Form
Ting Gao, Feng-Li Yan, Zhi-Xi Wang
The scheme for probabilistic teleportation of an N-particle state of general form is proposed. As the special cases we construct efficient quantum logic networks for implementing p…
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…
