- Laser breakthroughs in basic science
Prof. Haroche will review breakthroughs in basic science which have been made possible by lasers over the last six decades. They have achieved in the laboratory the highest temperatures existing in the core of the stars and also the lowest ones, at a few billionth of a degree from absolute zero, where matter takes exotic quantum forms. At the microscopic scale, lasers allow us to manipulate single atoms and photons and, at the cosmic scale, to observe gravitational waves generated billions of light years away from Earth. With lasers, we have developed clocks measuring long time intervals with an uncertainty of less than a second over the age of the universe, and produced light pulses lasting a few billionth of a billionth of a second, permitting the observation of the ultrafast phenomena taking place within atoms, molecules or condensed matter systems. These achievements in so many different fields and at such different scales illustrate the crucial and ubiquitous role played in basic science by this extraordinary source of light.

- Rydberg atoms in Cavity QED and in quantum metrology
Over the last twenty five years, the research group led by prof. Haroche has used Rydberg atoms as an essential tool in Cavity QED and quantum Information experiments. Prof. Haroche will review the latest achievements, which include the generation and study of large Schrödinger cat states of light and the use of single-Rydberg atom interferometry to measure electric and magnetic fields with a precision beating the standard quantum limit. He will discuss possible developments and practical applications of these studies.
