基于4粒子纠缠态的量子安全直接通信
Quantum Secure Direct Communication via Four-Partile Entangled States

提出了一个利用4粒子纠缠态实现量子安全直接通信的方案.在该方案中,由于携带信息的粒子不需要在公共信道上传输,使得这一方案是决定性的和安全的.
A novel quantum secure direct communication scheme by using four-partile entangled states is proposed.In the scheme,the information-carrying qubits do not need to be transmitted over the public channel.Therefore,this scheme is determinate and secure
