| 摘 要： | 本文研究了小世界复杂网络中的长程量子纠缠态的制备。提出了量子纠缠渗流优化网络量子通信的方案。通过在经典纠缠渗流协议(CEP)中引入局域化的"target-swap"量子操作,形成量子纠缠渗流协议(QEP)。研究表明QEP在长程纠缠制备的效能方面明显优于CEP,通过度分布变化的分析解释了QEP具有优势的原因。

| Abstract: | Long-distance entanglement establishment is investigated on small-world complex network topologies. The quantum entanglement percolation (QEP) protocol is proposed to optimize networked quantum communications. If the additional local "target-swap" quantum operations are performed in the classical entanglement percolation (CEP) protocol, the QEP can be obtained. The QEP has great advantage over CEP with respect to the efficiency of long-distance entanglement establishment. The advantage may be due to the changes of the degree distributions in the QEP. |
