Pushing the boundaries of optics
The invisible made visible: Using entangled photons and interference effects, infrared spectra of molecules (here: methane) can be recorded by cameras that can only detect visible light.

Quantum mechanically entangled light particles break down the boundaries of conventional optics and allow a glimpse into previously invisible wavelength ranges, thus bringing about new possibilities for imaging techniques, microscopy and spectroscopy. Unearthing these possibilities and creating technological solutions was the goal of the Fraunhofer lighthouse project QUILT, the results of which are now available.
