Abstract

本申请涉及量子通信技术领域，具体涉及一种量子通信芯片及系统。该芯片包括马赫曾德干涉仪，用于接收泵浦光脉冲,并产生两个泵浦光脉冲,两个泵浦光脉冲的到达时间不相同；单光子产生装置，用于接收泵浦光脉冲，并产生一对与泵浦光脉冲的波长不同且形成时间纠缠量子态的光子对；第一滤波器，用于滤除两个泵浦光脉冲，得到两个单光子；分光器，用于接收两个单光子，并分别建立两个单光子各自的传播路径，并按照传播路径将两个单光子通过第一光纤芯片耦合器发送至相邻的两个量子通信节点。该芯片产生的时间相互纠缠的单光子对，从而能够用于量子隐形传态，并实现通过中继产生远距离相互纠缠或者量子态的远程传递，最终增加了量子通信的距离。
