| Abstract: | We present in this paper a quantum secure direct communication
(QSDC) protocol by using partially entangled states. In the scheme a
third party (Trent) is introduced to authenticate the participants.
After authentication, Alice can directly, deterministically and
successfully send a secret message to Bob. The security of the
scheme is also discussed and confirmed. |
