# Serge Haroche

> Serge Haroche is a French physicist at the Collège de France and École Normale Supérieure, recognized for his pioneering work on quantum electrodynamics in cavity systems. He developed methods to trap and measure individual photons inside microwave cavities without destroying them — a direct experimental realization of quantum non-demolition measurement. Using Rydberg atoms as quantum probes, Haroche and his team observed the photon number states of a field, watched photon birth and death events in real time, and directly observed the decoherence of quantum superpositions. These experiments provided unprecedented insight into the quantum-to-classical transition and the fragility of quantum information. Haroche shared the 2012 Nobel Prize in Physics with David Wineland for their complementary methods of controlling and measuring quantum systems. His techniques are directly relevant to the development of quantum computers, quantum memory, and quantum communication protocols, and have inspired analogous experiments in superconducting circuits and ion traps.
