Our recent demonstration of a secret key exchange over a record distance of 421 km of optical fibre has been published in PRL as an Editor's suggestion as well as being featured in Physics Viewpoint. We push the limits to new heights by optimising all parts of the QKD system including increasing the generation rate of the quantum states to reach 2.5 GHz and high performance single-photon detectors developed in-house, which have very high efficiency and low noise. Finally, a new encoding method…

"The Quantum Technologies Roadmap – A European community view" by the European Quantum Flagship - Written by a diverse set of leading researchers, they review the current status of the field, and map out the prospects and challenges for the future. Recently quantum technologies have received a lot of public attention: governments have launched large research programmes like the European QT flagship initiative. This article presents an updated summary of the quantum technology roadmap that has…

We present a 2.5 GHz quantum key distribution setup with the emphasis on a simple experimental realization. It features a three-state time-bin protocol based on a pulsed diode laser and a single intensity modulator. Implementing an efficient one-decoy scheme and finite-key analysis, we achieve record breaking secret key rates of 1.5 kbps over 200 km of standard optical fibers.

The Swiss National Science Foundation (SNSF) and the Commission for Technology and Innovation (CTI) continuously monitor the changing context of research and innovation in Switzerland. They found that some interesting projects could be lost when they fell between the types of encouragement given by these two institutions. In the context of the 2017-2020 FRI message, the SNSF and CTI were commissioned by the Federal Council - on their own initiative - to jointly develop the Bridge Special…
