The initial results puzzled the world three years ago: the size of the proton (to be precise, its charge radius), measured in exotic hydrogen, in which the electron orbiting the nucleus is replaced by a negatively charged muon, yielded a value significantly smaller than the one from previous investigations of regular hydrogen or electron-proton-scattering. ...
Most molecules, including those of importance in medical diagnostics or pollution monitoring, have characteristic “fingerprints” in the mid-infrared spectral region. However, state-of-the-art mid-infrared frequency comb techniques require systems that are often costly and limited in their applications.

LMU/MPQ-Wissenschaftler entwickeln ein System, das die Verschränkung von stationären Quantensystemen anzeigt, ohne diesen Zustand zu zerstören. Das Experiment ist ein wichtiger Schritt auf dem Weg, Quanteninformation über große Entfernungen zu übertragen.
Laser frequency combs can be used for the calibration of astronomical spectrographs. This will help to find extra-solar planets. Stars outside our solar-system. By refining this technology it might become possible to directly measure even very small changes in the expansion velocity of the universe.
In future, optical fibers could connect all optical atomic clocks within Europe – a milestone for various users of optical frequencies in research and industry.
