摘　　要：提出了一个基于非纠缠直积态的量子密钥分配协议.Alice和Bob它们双方通过做局部测量和交换量子位建立起相同的密钥.任何第三者窃取密钥不可能不被发现,所以该协议非常安全.该协议只需要非纠缠直积态,也不需要做复杂的量子操作和集体测量,因此,它非常容易在实际中实现.This paper provides a quantum key distribution protocol based on untangled product states. It uses a set two -particle quantum systems in orthogonal product quantum states. The two parties establish the key by exchanging particles and performing the local measurement. No other people can get the key without being found. So the protocol is secure. There are no entangled states and complex quantum operations and collective measurements in the protocol. So it is easier to carry out in practice.
