Haroche studies the interaction of atoms and light, with experiments that measure individual quantum systems while preserving the information needed to follow their evolution.
Collège de FrancearXiv / NatureMeasuring a photon usually absorbs it. Haroche and collaborators developed cavity experiments that instead use atoms to probe stored microwave light repeatedly. This makes measurement itself part of the controlled quantum dynamics, connecting quantum optics with the study of decoherence and the boundary between quantum and classical behavior. His wider-directory profile recognizes that research contribution without implying that a cavity experiment is a complete commercial quantum computer.

Work, in context- 2007
Following the quantum jumps of a photon
With Sébastien Gleyzes and collaborators, Haroche coauthored an experiment that repeatedly probed microwave photons in a superconducting cavity using non-absorbing atoms, recording changes in photon number.
Coauthored experiment led in authorship by Sébastien Gleyzes, with Stefan Kuhr, Christine Guerlin, Julien Bernu, Samuel Deléglise, Ulrich Busk Hoff, Michel Brune, Jean-Michel Raimond and Serge Haroche.
