摘要:

提出了一种基于量子加密的量子安全直接通信方案。两个授权用户重复使用共享的纯纠缠对序列(量子密钥)直接对传输光子携带的秘密信息进行加密和解密。为了检验窃听,双方在每轮前对一些诱饵粒子进行单光子测量。该方案的优点是纯纠缠量子信号源目前是可行的,任何窃听者都无法窃取消息。

英文摘要:

We present a scheme for quantum secure direct communication with quantum encryption. The two authorized users use repeatedly a sequence of the pure entangled pairs (quantum key) shared for encrypting and decrypting the secret message carried by the traveling photons directly. For checking eavesdropping, the two parties perform the single-photon measurements on some decoy particles before each round. This scheme has the advantage that the pure entangled quantum signal source is feasible at present and any eavesdropper cannot steal the message.
