The quantum key to seeing through chaos

Researchers from the Institut des NanoSciences de Paris, the Kastler Brossel Laboratory and the University of Glasgow have developed an innovative method that renders a scattering medium transparent solely for information carried by entangled photon pairs, while the same medium remains completely opaque to classical light.

Concept and experimental results.

First thing I thought of was communication satellites sending entangled signals though storm clouds to get clear signals.
