Quantum Sensing with Atoms and Light

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

Onur Hosten’s research centers on developing innovative techniques to control the 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.

The Hosten group will focus 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, the group aims to build precision force sensors, and in the process, seek to gain insight into fundamental topics like the nature of quantum measurements. Using these sensors, the group’s long-term goal is to explore challenging experimental questions such as the nature of dark matter, and the interplay between quantum mechanics and gravity.
