Quantum Sensing and Metrology

Quantum Sensing and Metrology

This fields aims at harnessing new approaches that use the principles of quantum physics in order to overcome the noise produced by quantum fluctuations. The applications range from the improvement and synchronization of atomic clocks, the detection of the magnitude and direction of tiny magnetic fields, and interferometric measurements of phase shifts. So far, different platforms, including trapped ions, cold atoms, atomic ensembles, and solid-state atom-like systems, have been used to obtain the best measurements in different scenarios. The combination of theoretical and experimental techniques is giving rise to new methods to overcome quantum noise and to develop novel sensing modalities. Researchers at Harvard and MPG have made ground-breaking contributions in this field, both in understanding and overcoming the role of quantum noise in precision measurements, as well as developing, implementing, and applying new techniques to problems ranging from fundamental physics orksto material science, chemistry and biology.
