| Abstract: | A theoretical scheme of quantum secure communicationusing a class of three-particle W states is proposed. In the scheme, twocommunicators may communicate after they test the security of the quantumchannel. The receiver can obtain the secret message determinately if thequantum channel is safe. The present scheme can be realized without usingteleportation. |
