Abstract:

量子通信具有绝对安全、保密的优势,将量子通信与传统移动通信二者的优点相结合,构造安全、保密、灵活、高效的量子移动通信系统是未来移动通信的发展方向,关于量子移动通信越区切换的研究目前尚未展开。为了解决量子移动通信系统的越区切换问题,提出了基于纠缠度计算的量子越区切换算法。根据用户位置的变化情况,首先定义了量子移动终端与量子基站天线之间的纠缠度,然后分析了影响该纠缠度的各种因素,最后对移动用户在各扇区之间的切换进行了深入分析和计算。研究结果表明,本文所提出的基于纠缠度计算的量子越区切换算法具有很好的可操作性和可实现性。本文对于构建未来量子移动通信系统及其标准的制定有着重要的技术支撑作用。
