论文摘要
我们展示了一个三节点量子网络，用于使用Fermi和Argonne国家实验室之间的2对部署的纤维，用于C波段光子对。 C带对使用标准的电信开关将C-Band对定向到节点，并使用共存的O-或L波段光学时钟分配系统同步到PICSECOND尺度的计时分辨率。由于O波段脉冲的拉曼散射，我们衡量C波段对的巧合与事故比率（CAR）从51 $ \ pm $ 2至5.3 $ \ pm $ 0.4。尽管减少了这种减少，但汽车仍然适用于量子网络。
We demonstrate a three-node quantum network for C-band photon pairs using 2 pairs of 59 km of deployed fiber between Fermi and Argonne National Laboratories. The C-band pairs are directed to nodes using a standard telecommunication switch and synchronized to picosecond-scale timing resolution using a coexisting O- or L-band optical clock distribution system. We measure a reduction of coincidence-to-accidental ratio (CAR) of the C-band pairs from 51 $\pm$ 2 to 5.3 $\pm$ 0.4 due to Raman scattering of the O-band clock pulses. Despite this reduction, the CAR is nevertheless suitable for quantum networks.
