Quasi-deterministic secure quantum communication using non-maximally entangled states
This addresses secure communication for quantum networks, but it appears incremental as it builds on existing entanglement-based methods.
The paper tackles the problem of secure quantum communication by proposing a quasi-deterministic scheme using non-maximally entangled states, achieving a maximum qubit efficiency of 33.333%.
Quantum communication in general helps deter potential eavesdropping in the course of transmission of bits to enable secure communication between two or more parties. In this paper, we propose a novel quasi-deterministic secure quantum communication scheme using non-maximally entangled states. The proposed scheme follows a simple procedure, and cases where the entanglement required can be significantly reduced to carry out the protocol successfully are discussed. Long sequences or the whole sequence of data can be sent after error checking for a potential eavesdropper. The maximum qubit efficiency of the proposed protocol is found to be 33.333%.
