Lecture title: How quantum metrology leads to a start up company in optical telecommunications.

Lecture abstract: Quantum metrology aims at using the specific properties of quantum mechanics to enhance the sensitivity of measurements. In the particular case of optics, it consists in ordering photons both in time and space. This can be applied to optical imaging, where beam positioning can be achieved beyond the vacuum noise limit in the sub nanometer scale, and to femtosecond optics, where time-sharing can be achieved with unprecedented sensitivity. Both high precision optical devices developed for these tasks and theoretical concepts linked to multimode aspect of light can now find application in optical telecommunications, where the trend toward ever-higher data rates requires more and more sophisticated optical techniques. I will show how a company based on fundamental physics can find applications and markets in purely classical optics domains.
