Professor Nicolas GISIN, Group of Applied Physics, University of Geneva Bio: Professor Nicolas Gisin was born in Geneva, Switzerland, in 1952. After a master in physics and a degree in mathematics, he received his Ph.D. degree in Physics from the University of Geneva in 1981 for his dissertation in quantum and statistical physics. The “Fondation Louis de Broglie” recognised this work with an award. After a post-doc at the University of Rochester, NY, he joint a start-up company, Alphatronix, dedicated to fiber instrumentation for the telecommunication industry. Initially head of the software, he quickly became responsible for the hardware-software interface. Four years later he joined a Swiss software company developing an image processing package which received the attention of the American journal “PC Magazine”. In 1988 an opportunity to join the Group of Applied Physics at the University of Geneva as head of the optics section brought him back to the academic life. At the time the optics section was entirely devoted to support of the Swiss PTT (now Swisscom). In order to get a critical mass and stability, the optics section under the impulse of Prof. N. Gisin started two new research directions, one in optical sensors, one in quantum optics. The telecom and the sensing activities led to many patents and technological transfers to Swiss and international industries. Several products had and still have a commercial success. The quantum optics activities are more basic research oriented. The main theme is to combine the large expertise of the group in optical fibers with basic quantum effects. More recently, the demonstration of quantum cryptography and of long distance quantum entanglement received quite a lot of attention as well from the international scientific community as from the press “grand public”. In 2009, he was awarded the First Biennial John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and their Applications. |

Quantum Key Distribution (QKD) and Quantum Random Number Generators (QRNG) are the first applications of quantum physics at the level of individual quanta. They emerged from very fundamental research on the foundations of quantum theory, but are nowadays commercially available and clients use them daily, usually obliviously.
Today’s research in QKD and QRNG spans a broad spectrum, from very applied research aiming at developing cheaper, faster and smaller devices, all the way to abstract academic research on the deep connections with quantum non-locality. In between, quantum networks occupy a central place. Several architectures are considered, some based on optical fibers, some on free space communication, including possibly satellites. Long distance quantum networks require repeaters; a first solution consists in using “trusted node repeaters”, a more futuristic and safer solution will exploit quantum teleportation and quantum memories.
