Quantum cryptology is a new method for secret communications.This new method utilizes the quantum nature of single photons. 量子密码术是一种实现秘密通信的新方法,它利用单光子的量子性质,借助量子密钥分配协议可实现数据传输的可证性安全。
In a quantum cryptographic system, any interloper tapping into the stream of photons will alter them in a way that is detectable to the sender and the receiver. 在量子密码系统里,任何窃取者在偷看光子束时都会更动到它,而被发送者或接收者察觉。
