Quantum physics inside a drop of paint

Inside a drop of paint, light is scattered so often that it seems impossible to demonstrate quantum effects. But despite the thousands of possible paths the light can take, like a drunk person inside a labyrinth, researchers of the University of Twente now show that there are just two exits. Depending on the light pattern that enters the paint, two photons always come out through the same exit, or through different ones – as though they avoid each other. The scientists of UT's MESA+ Institute for Nanotechnology publish about these remarkable findings in the Physical Review A journal.
