Abstract
A method and system for distributing quantum cryptographic keys among a group of user devices through a switch connected to the user devices are provided. A switch [1000] establishes a connection between two user devices [405a, 405b] according to a schedule. A Quantum Key Distribution (QKD) session is established between the two user devices [405a, 405b] to facilitate sharing of secret key material between the two user devices. Connections and QKD sessions may be established for different pairs of the user devices.
