Abstract
A first endpoint in a Quantum Key Distribution (QKD) system determines an operating mode for a hybrid transceiver for communicating in an optical communication session with a second endpoint. The operating mode is selected from a group containing a classical reception mode, a classical transmission mode, a quantum transmission mode, and a quantum reception mode. The first endpoint configures an input to a homodyne detector of the hybrid transceiver based on the operating mode and operates the hybrid transceiver in the operating mode for at least a portion of the optical communication session.
