Via #OPG_OpticaQ: Versatile wavelength-division multiplexed quantum key distribution network operating simultaneously in the O and C bands https://bit.ly/4jYSEMM #FiberOpticCommunications #StarNetworks 💡⚛️

This image shows a schematic diagram of a quantum communication setup. On the left, three "Alice" sources marked 1550, 1549, and 1310 send signals through components like deployed fiber, dWDM, and eWDM, leading to a VOA. On the right, within a dashed box labeled "Bob," the signals go through optics, eWDM, then to single photon detectors, and connect to a computer and time tagger.
