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.

A QKD terminal for quantum communication, comprising:
- a photon source configured to emit a pair of entangled photons on a QKD channel on a shared optical axis,
- a dynamic holographic device arranged downstream of the photon source on the QKD channel and configured to receive the pair of entangled photons on the shared optical axis, 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 method for quantum communication, comprising:
- generating, by an entangled photon source, a pair of entangled photons;
- directing the pair of entangled photons to a dynamic holographic device along a shared optical axis;
- and
- triggering, by a controller, the dynamic 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.
