Abstract
A node for a quantum key distribution (QKD) network includes an optical input that receives an optical pulse from a hub of the QKD network and an optical splitter that splits the optical pulse into an optical timing pulse and a pre-qubit pulse. The node also includes a qubit encoder controllable to encode the pre-qubit pulse into a photonic qubit; a qubit trigger circuit that controls, based on the optical timing pulse, the qubit encoder while the pre-qubit pulse propagates through the qubit encoder; and an optical output that transmits the photonic qubit to the hub.
