Abstract
Systems and methods for quantum key distribution in an optical network and quantum-secured optical channels. A node for operation in an optical network includes one or more degrees each connected to a corresponding optical span including one or more fibers; and one or more Quantum-Optical Service modules (QOSM) for each of the one or more degrees, each QOSM supporting Quantum Key Distribution (QKD) for establishing a quantum-secured channel and Optical Service Channel (OSC) functionality over the quantum-secured channel. A line amplifier system for operation in an optical network includes one or more optical amplifiers configured to amplify optical channels over an optical span in the optical network; and a trusted quantum repeater, connected to the optical span, and configured to support QKD for establishing a first quantum-secured channel and a second quantum-secured channel and OSC functionality over the first quantum-secured channel and the second quantum-secured channel.
