Caption
The team working with Christoph Marquardt and Gerd Leuchs transmitted pulses with an elliptical, horizontal contour (right) through the air. In the illustration, the squeezed form of the quantum state registered at the receiver can be clearly seen. The short transverse and long longitudinal axis here represent the spread of two properties which are linked to each other via Heisenberg's uncertainty principle. The property which is represented on the short axis assumes values only within a narrow range. The property shown on the long longitudinal axis has a larger spread of measured values. The transitions between the two extremes result in the elliptical shape. The corresponding representation of conventional, non-squeezed states has a circular contour.
