摘要
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.
