Scalable interferometric receiver for photon-efficient quantum communication
Michał Jachura, Marcin Jarzyna, Marcin Pawłowski, Konrad Banaszek · OSA Quantum 2.0 Conference · 2020
We describe a modular design for an optical receiver implementing projective measurements on multiple logical qubits encoded in the temporal degree of freedom of a single photon. Application to satellite quantum key distribution is discussed.
