摘要
介绍了一种安全的量子明文直接传送方案—乒乓协议,该协议通过对EPR纠缠对的局域操作能够进行确定性量子通信。
Quantum communication is a new crossing course combing with classic communication and quantum mechanics together. Current researches are most concentrated in quantum cryptographic, using in quantum secret communication, which are usually nondeterministic. There introduces a secure quantum direct communication scheme-the ping-pong protocol, which can exploit the nature of operation on blocks of EPR for deterministic secure direct communication.
