Secure Bidirectional Communication Protocol without Quantum Channel
Z. J. Zhang, Z. X. Man
In this letter we propose a theoretical deterministic secure direct bidirectional quantum communication protocol by using swapping quantum entanglement and local unitary operations…
Generalizing Several Theoretical Deterministic Secure Direct Bidirectional Communications to Improve Their Capacities
Z. J. Zhang, Z. X. Man
Several theoretical Deterministic Secure Direct Bidirectional Communication protocols are generalized to improve their capacities by introducing the superdense-coding in the case o…
Improving quantum dense key distribution
Z. J. Zhang, Z. X. Man
The capacity of the quantum dense key distribution (QDKD) [Phys. Rev. A69, 032310 (2004)] is doubled by introducing the dense coding. The security of the improved QDKD against eave…
Deterministic secure direct communication by using swapping quantum entanglement and local unitary operations
Z. J. Zhang, Z. X. Man
A deterministic direct quantum communication protocol by using swapping quantum entanglement and local unitary operations is proposed in this paper. A set of ordered EPR pairs in o…
Secure direct bidirectional communication protocol using the Einstein-Podolsky-Rosen pair block
Z. J. Zhang, Z. X. Man
In light of Deng-Long-Liu's two-step secret direct communication protocol using the Einstein-Podolsky-Rosen pair block [Phys. Rev. A {\bf 68}, 042317 (2003)], by introducing additi…
