Atomic Quantum Metrology

Objective

This project aims to detect magnetic fields with high spatial and temporal resolution and unprecedented sensitivity using ultra-cold atoms as interferometric sensors. The project will, on the one hand, test and demonstrate the most advanced concepts in the dynamic field of quantum metrology, and on the other hand, develop measurement techniques with the potential to transform existing fields and open new ones to study.
Quantum metrology is in an exciting phase: on the one hand, a long-held goal of improving gravita- tional wave detection appears near at hand. At the same time, atomic instruments including atomic clocks, atomic gravimeters and atomic magnetometers are setting records in detection of time, ac- celeration, and fields, with revolutionary potential in several areas. This has stimulated new theory, including remarkable proposals suggesting that long-established “ultimate” limits can in fact be sur- passed.
This project will study quantum metrology applied to atomic sensors by developing a versatile and highly sensitive cold atom magnetometer. We set an ambitious goal: to demonstrate record sensi- tivity, and then to improve on that sensitivity using quantum entanglement. This ground-breaking accomplishment will show the way to super-precise measurements in many fields.
Fundamental topics in quantum metrology will be explored using the advanced magnetometry sys- tem. Nonlinear quantum metrology proposes to surpass the Heisenberg limit using inter-particle interactions. Compressed sensing aims to surpass the Nyquist limit, obtaining more information than normally allowed.
