For one year Serge Haroche moves to the United States as a visiting post-doc, where he works together with Arthur Schawlow, a Nobel laureate in physics in 1983.

Since 2001 Serge Haroche is a Professor at the Collège de France and the holder of the Chair of Quantum Physics. Since September 2012, he additionally serves as it's Director. Serge Haroche and his wife Claudine, with whom he has two children, live in Paris.

Serge Haroche earns his PhD in 1964 and 1971 (following the two stage french system) under Claude Cohen-Tannoudi, the Nobel laureate in physics in 1997, with a work on dressed atoms.

In 1967 Serge Haroche is appointed to Professeur Agrégé of physics and Attaché de Recherches at the Centre national de la recherche scientifique (CNRS). In 1971 he's advanced to a Chargé de Recherche and to a Maître de Recherche in 1973.

Serge Haroche develops new laser spectroscopy methods based on the study of quantum beats and superradiance. He also works on giant atoms called Rydberg atoms, which are sensitive to microwaves and can show the interactions between light and matter.

Through experiments Serge Haroche and his colleagues find a decoherence at the quantum mechanics in 1996. It shows the formation of macroscopic distinguishable "classical" states of quantum mechanical superposition states and can be seen as the realization of the thought-experiment of Schrödinger's Cat.

Together with the American physicist David Wineland Serge Haroche is awarded the Nobel Prize in physics in 2012 "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems."

From 1975 till 2001 Serge Haroche is appointed to a professorship at the Université Pierre et Marie Curie. During this period he is also a visiting professor at Harvard University in 1981 and at Yale University from 1984 till 1993.

Serge Serge Haroche is born to his parents Albert and Valentine, née Roubleva in 1944. His father, a Moroccan lawyer and his mother, a Russian teacher, are both Jewish. Serge Haroche grows up bilingually, French and Russian.

Between 1973 and 1984 Serge Haroche teaches as a Maître de Conference at École Polytechnique.

From 1963 till 1967 Serge Haroche studies physics at the Ecole Normale Supérieure (ENS) and at the Faculté des Science of the Paris University.

In 1956 the French protectorate treaty ends and Serge Haroche and his family leave Morocco and move to France.

From 1994 till 2000 Serge Haroche is the chairman of the Physics Department at the Ecole Normale Supérieure de Paris.
