摘要

摘要最近，我们实现了一种基于基本星形纠缠的无可信节点量子密钥分发网络。它允许多个用户之间同时进行量子密钥的成对交换。在本文中，我们从几个方面来展示它的灵活性。我们展示了在部分部署的100公里光纤链路上连续运行数天的系统，以及通信伙伴的动态重新配置。光子对源可以通过SPDC产生ii型或0型光子对，以及各种解复用策略和重复率。

Flexible reconfigurable entanglement-based quantum key distribution network

Abstract Recently, we implemented a basic star-shaped entanglement-based quantum key distribution network without trusted nodes. It enables simultaneous pairwise exchange of quantum keys between multiple users. In this paper, we demonstrate its flexibility by focusing on several aspects. We show continuous system operation over a partially deployed 100 km fiber link for multiple days as well as dynamic reconfiguration of the communication partners. The photon pair source enables type-II or type-0 photon pair generation by SPDC as well as various demultiplexing strategies and repetition rates.
