Quantum cryptology is a new method for secret communications.This new method utilizes the quantum nature of single photons. 量子密碼術(shù)是一種實(shí)現秘密通信的新方法，它利用單光子的量子性質(zhì)，借助量子密鑰分配協(xié)議可實(shí)現數據傳輸的可證性安全。
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. 在量子密碼系統里，任何竊取者在偷看光子束時(shí)都會(huì )更動(dòng)到它，而被發(fā)送者或接收者察覺(jué)。
