DESCRIPTION:Prof. Nicolas Gisin\, GAP-Optique\, Univ. Genève\nQuantum com
 munications is the art of transferring a quantum state from one location t
 o a distant one. On the fundamental side\, quantum communication is fascin
 ating because it illustrates the power of entanglement and of non-local qu
 antum correlations. On the application side\, quantum communication is alr
 eady relatively advanced with Quantum Random Number Generators and Quantum
  Key Distribution (QKD) systems having found niche markets. On the academi
 c research side quantum communication has still a long way to go until a f
 unctional quantum repeater can extend the distances to continental scales.
  Quantum repeaters are based on quantum teleportation\, the most fascinati
 ng application of entanglement. Additionally\, quantum repeaters require q
 uantum memories with memory times close to a second\; this represents one 
 grand challenge for quantum communication. Entangling two quantum memories
 \, that is two crystal\, raises the fascinating question of “what is lar
 ge entanglement?”.\nBio: Prof Nicolas Gisin was born in Geneva\, Switzer
 land\, in 1952. After a post-doctoral degree at the University of Rocheste
 r\, NY\, in 1984 he joined a start-up company\, Alphatronix\, dedicated to
  fiber instrumentation for the telecommunication industry.\nIn 1988 an opp
 ortunity 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 th
 e time the optics section was mostly working on classical communication. P
 rof. Gisin invented the measurement technique for Polarization Mode Disper
 sion most widely used today. In the early 1990’s Prof. Gisin started res
 earch in quantum optics. The main focus is to combine the group's broad ex
 pertise in optical fibers with a study of basic quantum effects. In 1993 h
 is group demonstrated quantum cryptography under Lake Geneva.\nIn 2009 he 
 received the first John S. Bell award for the demonstrations of long dista
 nce entanglement and quantum teleportation\, together with his numerous co
 ntributions to the theory of Bell inequalities. His group is world leader 
 in quantum communication. In 2001 he co-founded ID Quantique.
