Resource and Duration Evaluation of Quantum Secure Communication Protocols

Abstract

The paper proposes resource and duration evaluations for quantum secure communication (QSC) protocols. In terms of both evaluations, two QSC protocols – two-step quantum secure direct communication (QSDC) protocol and quantum channel compression (QCC)-based QSDC protocol, are compared. It is verified that the QCC-QSDC protocol excels the two-step QSDC in terms of duration, and utilizes slightly less resources for its implementation.
