量子路由器量子簇分片量子纠缠 quantum router quantum cluster fragment quantum entanglement

摘要

在量子通信网络中, 量子路由器因自身性能的限制, 使其能够存储转发的量子簇长度是有限的。由于量子城域网和广域网数据量庞大, 会导致大量量子簇因长度限制问题无法转发而只能以量子分组的形式进行数据传输。为了解决上述问题, 提出了一种量子簇分片传输方案, 其将不能够直接被量子路由器存储转发的量子簇, 通过分片将其分解为若干个长度较短的、能够直接被路由器存储转发的分片量子簇完成数据传输。仿真结果表明: 在数据量庞大的城域网和广域网中, 需要分片的量子簇数量多, 对于提出的量子簇分片传输方案, 与已有的量子簇数据传输方案相比, 其能够以较少的纠缠资源和较短的传输时间完成量子分组的数据传输, 具有较好的实际应用价值。

Abstract

In the quantum communication network, quantum routers can store and forward quantum clusters with limited length. In the metropolitan area network(MAN) and wide area network(WAN), date volumes are very large, as a result, a large number of quantum clusters can not be stored and forwarded because of the length constraint problem and can only be transmitted in the form of quantum packets. In order to solve the above problem, a fragment transmission scheme of quantum cluster was proposed, it fragmented the quantum clusters, which were not able to be stored and forwarded by the quantum router, so that the fragmented quantum cluster could satisfy the storage and forwarding condition of routers and could be directly transmitted. The simulation results show that in the MAN and WAN, a large number of quantum clusters need to be fragmented because of the large amount of date, so compared with the existing data transmission scheme based on quantum cluster, the proposed fragment transmission scheme of quantum cluster can achieve the data transmission by consuming the short time and less quantum entanglement resources, and own the better practical value.
