Experimental demonstration of spatial quantum correlations in multiple scattering media

Abstract

We demonstrate that spatial quantum correlations are induced by multiple scattering of squeezed light. The correlation relates multiple scattered photons at different spatial positions, and is tunable by varying photon fluctuations of the illuminating beam.

Observation of Spatial Quantum Correlations Induced by Multiple Scattering of Nonclassical Light

Stephan Smolka, Alexander Huck, Ulrik L. Andersen +2 more

We present the experimental realization of spatial quantum correlations of photons that are induced by multiple scattering of squeezed light. The quantum correlation relates photons propagating along two different light paths through the random medium and is infinite in range. Both positive and negative spatial quantum correlations are observed when varying the quantum state incident to the multiple scattering medium, and the strength of the correlations is controlled by the number of photons. The experimental results are in excellent agreement with recent theoretical proposals by implementing the full quantum model of multiple scattering.

We present the first angle-resolved measurements of spatial photon correlations that are induced by multiple scattering of light. The correlation relates multiple scattered photons at different spatial positions and depends on incident photon fluctuations.

Spatial Quantum Correlations Induced by Random Multiple Scattering of Quadrature Squeezed Light

Peter Lodahl

The authors demonstrates that spatial quantum correlations are induced by multiple scattering of quadrature squeezed light through a random medium. As a consequence, light scattered along two different directions by the random medium will not be independent, but be correlated to an extent that can only be described by a quantum mechanical theory for multiple scattering. The spatial quantum correlation is revealed in the fluctuations of the total intensity transmission or reflection through the multiple scattering medium.

Spatial quantum correlations induced by multiple scattering of light

It is experimentally demonstrated how quantum noise of light is transported through a multiple scattering random medium. We predict the existence of novel spatial quantum correlations that are induced by multiple scattering.

Quantum correlations induced by multiple scattering of quadrature squeezed light

Peter Lodahl

Propagating quadrature squeezed light through a multiple scattering random medium is found to induce pronounced spatial quantum correlations that have no classical analogue. The correlations are revealed in the number of photons transported through the sample that can be measured from the intensity fluctuations of the total transmission or reflection. In contrast, no pronounced spatial quantum correlations appear in the quadrature amplitudes where excess noise above the shot noise level is found.

Spatial Quantum Correlations in Multiple Scattered Light

Peter Lodahl, Allard P. Mosk, Ad Lagendijk

We predict a new spatial quantum correlation in light propagating through a multiple scattering random medium. The correlation depends on the quantum state of the light illuminating the medium, is infinite in range, and dominates over classical mesoscopic intensity correlations. The spatial quantum correlation is revealed in the quantum fluctuations of the total transmission or reflection through the sample and should be readily observable experimentally.
