Quantum optics in multiple scattering random media

The paper presents the first experimental study of the propagation of quantum noise through an elastic, multiple scattering medium. Two different types of quantum noise measurements have been carried out: total transmission and short-range frequency correlations. When comparing shot noise (quantum) to technical noise (classical) a markedly different behavior is observed. The experimental results are found to be in agreement with a quantum model for multiple scattering of light, which allows extracting both static and dynamic scattering properties of the medium. A new quantum correlation in multiple scattering is proposed
