Q 51.3: Talk

Thursday, March 14, 2019, 14:30–14:45, S HS 002 Chemie

Towards quantum communication with single spins in silicon carbide — •Florian Kaiser, Roland Nagy, Charles Babin, Izel Gediz, Erik Hesselmeier, Timo Görlitz, Rainer Stöhr, Roman Kolesov, and Jörg Wrachtrup — 3rd Institute of Physics, University of Stuttgart and Institute for Quantum Science and Technology IQST (Germany)

The only known means to establish provably secure communication are based on quantum key distribution. Long-distance quantum networking will rely on quantum repeater nodes. In this talk, we will present our first results and future visions on the realisation of such networks using optically interfaced single spins in silicon carbide [1]. We will estimate achievable communication rates and discuss possible improvements based on nuclear spin quantum memories and photonic crystal cavities.
