Abstract

A quantum communications system may include 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 at least one Talbot effect image position along the quantum communications channel. The receiver node may be located along the quantum communications channel at the at least one Talbot effect image position.
