Quantum Sensing with Atoms and Light

How can we better understand and exploit the quantum mechanical world of atoms and light?

The Hosten Group aims to develop innovative techniques to control quantum properties of atomic and optical systems with an eye towards applications in the domain of quantum-enabled technologies. A prime example of these technologies is precision sensing.

Our research focuses on developing new sensing methods that gainfully utilize the phenomenon of quantum entanglement. By manipulating the collective properties of cold atomic ensembles in optical cavities, our group intends to build precision sensors of time, force, acceleration, and in the process gain insight into fundamental topics like the nature of quantum measurements. Using these sensors, the long-term goal is to explore challenging experimental questions such as the nature of dark matter, and the interplay between quantum mechanics and gravity.
