Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

The biggest obstacle for long distance quantum communication is the channel loss and the
channel noise on photons. In this paper, a method to solve this problem was analyzed using …

A revised controlled deterministic secure quantum communication protocol using five-
photon entangled state is proposed. It amends the security loopholes pointed by Qin et al. in …

A novel quantum key distribution scheme based on the path-spin hybrid entanglement is
proposed and analyzed. In this proposed scheme, the entanglement between the path and …

Using dipole and quadrupole operators as the orthogonal basis of su (3) algebra and
successive Cartan decompositions, the decomposition of matrices for two coupled spin 1 …

By analyzing the basic properties of a class of three-particle W states, we show how to
establish a non-symmetric channel to realize a quantum dense code scheme, each quantum …

Violation of modified Wigner inequality in a binary bipartite quantum system allows the
discrimination between the quantum world and the classical local-realistic one, and also …

In this paper, we investigate the controllability of spin 1 systems and the realization of ternary
gates. Using dipole and quadrupole operators as the orthogonal basis of su (3) algebra, we …
