The QRANGE project, part of the quantum flagship initiative, and led by Hugo Zbinden at the University of Geneva, had the second of its consortium meetings in Stuttgart recently.

Some of our recent work on QKD over more than 400km was recently highlighted in a Scientific American article on progress towards a future quantum-enabled communication network.

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 group at the University of Geneva will lead on of the Quantum Technologies Flagship projects in a ten-year work programme with the ambitious long-term vision, to: • Consolidate and expand European scientific leadership and excellence in quantum research, including training the relevant skills; • Kick-start a competitive European industry in quantum technologies to position Europe as a leader in the future global industrial landscape; • Make Europe a dynamic and…

The Quantum Technologies group at the University of Geneva QFlag will play a key role to support and coordinate the activities of the Quantum Flagship - the initial selected projects, and the quantum community at large - into the world-leading success that all stakeholders would like it to be – this will assist both the science to evolve as well as gathering and triggering the stakeholders to liberate quantum technologies from the lab and turn it into commercially successful products.

The most awaited "Bar du Gap" is back September 28th, and we think you should not miss it! The theme for this year is "EXOTIC" so you have no excuse to arrive without a beautiful costume ;) Your creativity may even pay because this year there will be a "Best Costume Award".

"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…

Emna Amri has been awarded a 2018 Optics and Photonics Education Scholarship by SPIE, the international society for optics and photonics, for her potential contributions to the field of optics, photonics or related field.

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.
