Abstract:

Decoherence could set severe limitations to the fascinating promises of quantum 
information processing (the art of turning quantum conundrums into potentially 
useful processes). We present results from a Franson-type 2-photon 
interferometer showing that strong quantum correlations can be maintained over 
very large distances.



Biography:

Prof. Nicolas Gisin was born in Geneva, Switzerland, in 1952. He received his 
Ph.D. degree in Physics from the University of Geneva in 1981 for his 
dissertation in quantum and statistical physics.

After a post-doc at the University of Rochester, NY, and four years in the 
industry, he joined the Group of Applied Physics at the University of Geneva 
where he is he is head of the optics section since 1988. His research work 
ranges from quantum physics to fibers and integrated optics.
