One-party Quantum Error Correcting Codes for Unbalanced Errors: Principles and Application to Quantum Dense Coding and Quantum Secure Direct Communications
Kai Wen, Gui Lu Long
In this article, we present the unbalanced quantum error correcting codes(one-party-QECC), a novel idea for correcting unbalanced quantum errors. In some quantum communication task…
Mathematical Theory of the Duality Computer in the Density Matrix Formalism
Gui Lu Long
We give the mathematical theory of duality computer in the density matrix formalism. This result complements the mathematical theory of duality computer of Gudder in the pure state…
Proof of Security of a High-Capacity Quantum Key Distribution Protocol
Xiao-Wei Zhang, Kai Wen, Gui Lu Long
We prove the security of a high-capacity quantum key distribution protocol over noisy channels. By using entanglement purification protocol, we construct a modified version of the…
Multi-step quantum secure direct communication using multi-particle Green-Horne-Zeilinger state
Chuan Wang, Fu Guo Deng, Gui Lu Long
A multi-step quantum secure direct communication protocol using blocks of multi-particle maximally entangled state is proposed. In this protocol, the particles in a Green-Horne-Zei…
