摘要

密集波分复用技术（DWDM）是实现大容量和灵活量子通信网络的关键技术。此外，要实现新兴的量子互联网，量子频率转换对于在光纤网络上桥接不同的量子系统也至关重要。在这项工作中，我们展示了一种信道选择性量子频率转换（CS-QFC），它允许从多个 DWDM 信道中主动选择转换光子的频率。我们的 CS-QFC 系统具有 2.5 THz 的带宽，表明它有能力通过单个量子系统建立 100 通道的 DWDM 动态链路。它有望增加量子网络的多样性。

1xN DWDM channel selective quantum frequency conversion

Dense Wavelength Division Multiplexing (DWDM) is a key technology for realizing high-capacity and flexible quantum communication networks. In addition, to realize the emerging quantum internet, quantum frequency conversion is also essential for bridging different quantum systems over optical fiber networks. In this work, we demonstrate a channel-selective quantum frequency conversion (CS-QFC), which allows active selection of the frequency of the converted photon from multiple DWDM channels. The 2.5 THz bandwidth of our CS-QFC system shows the ability to establish a 100-ch DWDM dynamic link from a single quantum system. It promises to increase the diversity of the quantum network.
