Abstract
A quantum communications system includes a communications system that operates with a quantum key distribution (QKD) system, which includes a transmitter node, a receiver node, and a quantum communications channel coupling the transmitter node and receiver node. The transmitter node may cooperate with the quantum communications channel defining a Talbot effect image position along the quantum communications channel. The receiver node is located along the quantum communications channel at a midpoint of the Talbot effect image position.
