Quantum noise detection: a portable and educational system

Morizur, Jean-François; Colla, Massimiliano; Bachor, Hans


Quantum noise is a key feature of laser beams. It is both a limiting effect in contemporary optical measurements and a manifestation of the quantum nature of light. Its properties distinguish it from classical noise. We demonstrate a simple, reliable, and portable apparatus using low cost commercial lasers and electronics that provides evidence of these properties.
