Evaluation of nitrogen- and silicon-vacancy defect centres as single photon sources in quantum key distribution
Matthias Leifgen, Tim Schröder, Friedemann Gädeke +8
We demonstrate a quantum key distribution (QKD) testbed for room temperature single photon sources based on defect centres in diamond. A BB84 protocol over a short free-space trans…
