Sensing motion with cold atoms and ions

March 28, 2023

Sensors based on atoms enable high precision and accuracy which make them attractive for a range of applications including quantum sensing, quantum computation, and quantum simulation.  I will discuss two experiments at UCLA towards sensing motion with laser-cooled atoms.   The first borrows techniques from cavity quantum electrodynamics (QED) to use an optical cavity to directly read out the motion of an ensemble of atoms over sub-wavelength scales on a microsecond timescale.  The second experiment combines techniques from matter wave interferometry and quantum computation towards the development of a single ion gyroscope.
