以EPR纠缠为基础的量子密钥分配

Quantum Cryptography Based on EPR-entanglement

提出了一种以EPR纠缠为基础的新的量子密钥分配方案.不需要密钥双方Alice,Bob进行测量基的选择,提高了传输产生的密钥效率.同时,检测偷听者需要对比更少的量子位.

A theoretical quantum key distrbution scheme using EPR pairs is presented.This scheme dose not require that Alice and Bob choose between alternative measurements,therefore impoving the rate ofgenerated bits by transmitted qubits.At the same time,detecting Eve requires the comparison of fewer bits.
