通过粒子重排序实现量子安全直接通讯

Quantum secure direct communication via rearrange the orders of particles

量子安全直接通讯是对秘密信息的直接通讯,而不需要先制造一个分享的密钥.这种方案可以用于一些紧急的情况.利用粒子重排序的方法来实现量子安全直接通讯.此方案无需进行幺正操作,比ping-pong协议更为简便.而且该方案被证明在理想信道中是安全的.

Quantum Secure Direct Communication （QSDC） is the direct communication of secret messages without first producing a shared secret key. It can be used in some urgent circumstances. Here we propose a Quantum Secure Direct Communication （QSDC） scheme via rearrange the orders of particles. The protocol is more simple than ping -pang scheme because it dose not need implement unitary operation. And the security of the protocol has been proved in perfect quantum channel.
