A Versatile High-Speed Continuous-Variable Quantum Communication System — Imran Khan^1,2, •Stefan Richter^1,2, Kevin Jaksch^1,2, Kevin Guenthner^1,2, Ömer Bayraktar^1,2, Emanuel Eichhammer^1,2, Bastian Hacker^1,2, Birgit Stiller^1,2, Gerd Leuchs^1,2, and Christoph Marquardt^1,2 — ¹Max-Planck-Institute for the Science of Light, Erlangen, Germany — ²Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany

Over the last years, the quantum information processing group at MPL has developed a fiber-based continuous-variable quantum communication system for deployment alongside and compatible with existing telecom infrastructure. In this work, we present our technological advancements as well as the role of this fiber-based quantum communication system within national and EU quantum flagship projects. The projects covered are: HQS (BMBF), QuNET (BMBF), CiViQ (EU Quantum Flagship) and the European quantum key distribution testbed OPENQKD (EU H2020).
