Quantum Metrology

The group works with experimental setups in the laboratory, focusing on new ways to generate ultra stable frequency references with cold atoms or molecular gases. Here, atoms are trapped in magnetic fields, where they are held by precise beams of laser light and are cooled down to near absolute zero, minus 273 degrees Celsius.

The result is an atomic clock, a technology that is now so precise that it only loses one second over the entire 13.8 billion year lifetime of the universe. In the Quantum Metrology group we investigate the properties of such atomic clocks and work to improve them or develop the next generation systems. We focus especially on Cavity-enhanced systems and Cavity-QED.
