Nicolas Gisin (2015)

Nicolas Gisin (* 1952 in Geneva , Switzerland ) is a Swiss physicist , professor at the University of Geneva . He is known for working on the fundamentals of quantum mechanics and quantum cryptography .

Life

Gisin studied physics and mathematics at the University of Geneva , where he obtained his physics diploma and received his doctorate in physics in 1981. For his dissertation he received a prize from the Fondation Louis de Broglie . As a post-doctoral student he was at the University of Rochester , New York , and then from 1984 worked in a start-up company in the field of fiber optics for telecommunications (Alphatronix). Four years later he worked for a Swiss software development company that manufactured image processing software. In 1988 he moved to the chair of “Optical Systems” at the University of Geneva, where he established research focuses in the field of optical sensors and quantum optics. In 2001 he founded with Hugo Zbinden and Grégoire Ribordy the company ID Quantique (IDQ), whose chairman he is currently (2018).

He works both theoretically and experimentally.

Gisin developed a measurement method for polarization mode dispersion that is widely used today .

In 2003, MIT's Technology Review magazine counted his work on quantum cryptography among the 10 most promising inventions. He has been involved in experiments on quantum cryptography and quantum teleportation since the 1990s . In 2003 he demonstrated quantum teleportation in frequencies that are used in commercially available optical fibers over a distance of 2 km and in 2007 in commercial optical fiber networks (from Swisscom) over distances of 10 to 100 km. One problem with long-distance transmission is the need for repeaters. To this end, he and his group developed quantum memories in 2008 . In 2014 he showed quantum teleportation not only on photons, but also of photons on solid states over long distances (25 km).

In a work from 2006 he and colleagues showed that the information-theoretical security of protocols of quantum cryptography can be proven from observations alone, without recourse to quantum mechanics ( Bell's inequality also makes similar statements that are independent of the validity of quantum mechanics)

As part of the implementation of quantum teleportation and quantum cryptography in telecommunication networks, he also tested the quantum-mechanical non-locality (Einstein's spooky action at a distance ) in experiments of the type of violation of Bell-like inequalities over large distances.

In 2004 he and Sandu Popescu introduced the term quantum glove for the discussion of the intricacies of the distinction between information content and physical realization in quantum theory .

Honors

In 2009 he received the first John Stewart Bell Prize of the University of Toronto for the demonstration of entanglement and quantum teleportation over long distances and contributions to the theory of Bell inequalities , in 2014 the Marcel Benoist Prize and the International Quantum Communication Award . In 2017 he was awarded the Innovation Medal of the University of Geneva together with the other co-founders of ID Quantique.

As a hobby he plays field hockey.
