Research Overview
Our research focuses on developing quantum sensors to challenge fundamental limits of metrology and find new applications in precision measurement. We work at the intersection of atomic physics, quantum optics, and metrology to create novel sensing platforms with applications ranging from fundamental physics to practical quantum technologies.
How to engineer metrologically useful light-matter interactions?
We are developing a novel cavity QED platform to enable efficient interactions between trapped atoms and near-resonant light modes. Highly efficient interactions enable state preparation and control protocols that can be used to perform either atomic assisted laser interferometry or light assisted atom interferometry.
Key Research Goals:
- Develop ultra-low loss optical resonators for strong light matter interactions.
- Demonstrate cavity-enhanced atomic state preparation protocols.
- Investigate quantum-enhanced interferometry with atomic systems.
- Find applications; from rugged laser gyros to next-generation gravitational wave detectors
Can sensors operate on quantum precision and accuracy?
We are using laser cooled and trapped Helium atoms to build our quantum sensors. Because of their relatively simple electronic structure, calculable susceptibilities pave the way for not only precision scaling at or beyond the quantum limit, but also accurate measurement.
Helium Atom Advantages:
- Simple electronic structure enabling calculable accuracy.
- Large ground (metastable) state magnetic moment for magnetometry.
- Telecom-compatible optical clock transition.
- Strong response to near-field surface interactions.
- Large recoil possible for inertial sensing.
Applications to Fundamental Physics
We develop precision quantum sensors to enable tests of fundamental physics, including searches for dark matter, tests of general relativity, and mesoscopic phenomena. We are continously searching ways to design better measurements that probe the deepest questions in physics.
Fundamental Physics Applications:
- Dark matter and gravity detection through high resolution spectroscopy and quantum coherent control.
- Searches for new fundamental forces by near-surface metrology.
- Quantum decoherence in mesoscopic systems with microscopic atomic witnesses.
