Emerging Talents: Florian Fröwis

The Editorial Board of Journal of Physics A has selected Florian Fröwis to contribute to the special issue: Emerging Talents as part of the Journal of Physics series’ 50th anniversary celebrations in 2017. His paper “Lower bounds on the size of general Schrödinger-cat states from experimental data” was now published in this special issue.







 

Temporal multimode storage of entangled photons

Our paper demonstrating the multimode storage of two entangled photons in the solid-state quantum memory recently has been published in Physical Review Letters. Our results conclusively demonstrate the capability of the rare-earth ion doped crystals for future multiplexed quantum communication over the long distances.

This work was a collaboration between several groups, Nicolas Brunner and Marcus Huber here in Geneva on the theory side, and experimentally, Sae Woo Nam's group in NIST and Francesco Marsilli's group at JPL, whose superconducting single photon detectors we used for the experiment.

 

Сommenting on the famous Bell’s inequalities

PhysicsWorld.com publishes comments written by Prof. Nicolas Gisin about the new book "John Stewart Bell and Twentieth-Century Physics: Vision and Integrity" by Andrew Whitaker. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. The book describes not only his major contributions to quantum theory, but also his relatively humble origins and struggles to obtain secondary and university education.








 

Video - Guest Lecture Quantum key distribution in practice

In the recent video lecture Professor Nicolas Gisin and Dr. Matthieu Legré introduce to the practical implementations of Quantum Key Distribution in ID-Quantique and its commercialisation efforts. They explain the commercial side of Quantum Key Distribution (QKD), Quantum Random Number Generator (QRNG) and their impact for modern technologies.
