摘要

In light of a quantum secure direct communication (QSDC) scheme using entanglement swapping [Chin. Phys.Lett. 22 (2005)18], by introducing additional local operations for encoding, we propose a bidirectional QSDC (BQSDC) protocol, in which two legitimate users can simultaneously exchange their respective messages.
