中文摘要	提出了一种基于纠缠交换和经典交换的量子局域网方案.采用载波侦听多址/碰撞检测协议实现多址,由经典交换机传送建立和释放信道等控制消息,通过纠缠交换建立收发端光子的纠缠,基于量子隐形传态的原理传递量子信息.对该量子局域网进行性能分析,结果表明系统传输量子信息的吞吐率随着通信双方成功建立纠缠的概率、发端成功进行Bell态测量的概率和接收端成功检测到发送量子比特的概率增大而显著增加.; This paper presents a scheme for Quantum Local Area Networks(QLAN) based on entanglement swapping and classical switching,in which the Carrier Sense Multiple Access with Collision Detection(CSMA/CD) protocol is applied to implement multiple users communication,the message on building and releasing channel,etc.is transferred by the classical switch,and the entanglement of photons between sender and receiver is built by entanglement swapping and quantum information is transferred by the principle of quantum teleportation.Performance analysis results show that the throughput of QLAN increases greatly with higher probabilities with which entanglement is built between sender's photons and receiver's photons,the sender finishes the joint Bell state measurement successfully and the receiver detects the sender's qubit information,respectively.; 国家自然科学基金资助项目(60132030,60572147)
