Quantum communications is the art of transferring a quantum state from one location to a distant one. On the fundamental side, quantum communication is fascinating because it illustrates the power of entanglement and of non-local quantum correlations. On the application side, quantum communication is already relatively advanced with Quantum Random Number Generators and Quantum Key Distribution (QKD) systems having found niche markets. On the academic research side quantum communication has still a long way to go until a functional quantum repeater can extend the distances to continental scales. Quantum repeaters are based on quantum teleportation, the most fascinating application of entanglement. Additionally, quantum repeaters require quantum 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 large entanglement?”.
Bio: Prof Nicolas Gisin was born in Geneva, Switzerland, in 1952. After a post-doctoral degree at the University of Rochester, NY, in 1984 he joined a start-up company, Alphatronix, dedicated to fiber instrumentation for the telecommunication industry.
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 mostly working on classical communication. Prof. Gisin invented the measurement technique for Polarization Mode Dispersion most widely used today. In the early 1990’s Prof. Gisin started research in quantum optics. The main focus is to combine the group's broad expertise in optical fibers with a study of basic quantum effects. In 1993 his group demonstrated quantum cryptography under Lake Geneva.
In 2009 he received the first John S. Bell award for the demonstrations of long distance entanglement and quantum teleportation, together with his numerous contributions to the theory of Bell inequalities. His group is world leader in quantum communication. In 2001 he co-founded ID Quantique.
