Qkd terminal, qkd system and method for quantum communication

Abstract

A QKD terminal for entangled photon Quantum Key Distribution, including: a photon source configured to emit a pair of entangled photons on a QKD channel, a dynamic holographic device arranged downstream of the photon source on the QKD channel and configured to receive and redirect the pair of entangled photons; and a controller connected to the holographic device and configured to trigger the holographic device to redirect a first entangled photon of the pair of entangled photons to a first direction and a second entangled photon of the pair of entangled photons to a second direction different from the first direction. A QKD system and a method for quantum communication are also provided.

Dependencies are inferred from the claim text.
