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.
Fraunhofer IPM contributed to the success of the project by a world first, the »Quantum FTIR«, which is the quantum optical equivalent to the classical Fourier transform spectrometer.
