DESCRIPTION:Professor Nicolas GISIN\, Group of Applied Physics\, Universit
 y of Geneva\nBio: Professor Nicolas Gisin was born in Geneva\, Switzerland
 \, in 1952. After a master in physics and a degree in mathematics\, he rec
 eived his Ph.D. degree in Physics from the University of Geneva in 1981 fo
 r his dissertation in quantum and statistical physics. The “Fondation Lo
 uis de Broglie” recognised this work with an award.\nAfter a post-doc at
  the University of Rochester\, NY\, he joint a start-up company\, Alphatro
 nix\, dedicated to fiber instrumentation for the telecommunication industr
 y. Initially head of the software\, he quickly became responsible for the 
 hardware-software interface. Four years later he joined a Swiss software c
 ompany developing an image processing package which received the attention
  of the American journal “PC Magazine”.\nIn 1988 an opportunity to joi
 n 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 opti
 cs 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 i
 n optical sensors\, one in quantum optics. The telecom and the sensing act
 ivities led to many patents and technological transfers to Swiss and inter
 national industries. Several products had and still have a commercial succ
 ess. The quantum optics activities are more basic research oriented. The m
 ain 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 lo
 t of attention as well from the international scientific community as from
  the press “grand public”.\nIn 2009\, he was awarded the First Biennia
 l John Stewart Bell Prize for Research on Fundamental Issues in Quantum Me
 chanics and their Applications.\nQuantum Key Distribution (QKD) and Quantu
 m Random Number Generators (QRNG) are the first applications of quantum ph
 ysics at the level of individual quanta. They emerged from very fundamenta
 l research on the foundations of quantum theory\, but are nowadays commerc
 ially available and clients use them daily\, usually obliviously.\nToday
 ’s research in QKD and QRNG spans a broad spectrum\, from very applied r
 esearch aiming at developing cheaper\, faster and smaller devices\, all th
 e way to abstract academic research on the deep connections with quantum n
 on-locality. In between\, quantum networks occupy a central place. Several
  architectures are considered\, some based on optical fibers\, some on fre
 e space communication\, including possibly satellites. Long distance quant
 um networks require repeaters\; a first solution consists in using “trus
 ted node repeaters”\, a more futuristic and safer solution will exploit 
 quantum teleportation and quantum memories.
