摘要
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,分析了影响该纠缠度的各种因素,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,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。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。
In order to deal with quantum mobile communication system handover, the handover algorithm of quantum mobile communication based on entanglement degree computing is proposed. According to the alteration of user's location, it defines entanglement degree on quantum mobile terminal and the antenna of quantum base station firstly. Then various impact factors of entanglement degree are analyzed. Then analysis and calculations are carried out for the mobile users to handover between the various sectors finally. The results show that the proposed handover algorithm of quantum mobile communication based on entanglement degree computing has a good operability and can be realized. The algorithm plays an important technical support role in building the future quantum mobile communication systems and standard setting.
