SUMMARY:IQUIST Seminar: Photonic Engineering of Atomic Sensors\, Wisco
 nsin Quantum Institute\, Jennifer Choy\, UW–Madison Engineering Phys
 ics
DESCRIPTION:The discrete electronic energy levels in atoms and the abi
 lity to probe and control them using their interactions with electroma
 gnetic fields have enabled a host of applications in quantum sensing a
 nd metrology\, including atom-based time and frequency standards\, mag
 netometers\, and inertial sensors. Precision measurements with atoms r
 ely on the capability to control the frequency\, phase\, polarization\
 , and direction of photons used to prepare and measure quantum systems
 \, and thus developments in near-infrared optics and photonics are cri
 tical to advancing state-of-the-art atomic sensors. In this talk\, I w
 ill summarize the basic principles of atom-based quantum sensing and h
 ighlight the role of atom-photon interactions in quantum measurements.
  The benefits and challenges of realizing atom-based quantum sensors w
 ill be illustrated through examples from my prior research\, including
  the development of sensitive accelerometers and gyroscopes based on c
 old-atom interferometers. I will discuss the critical developments in 
 photonic engineering that are still needed to improve the performance 
 and functionality of atom-based-quantum sensors and our research progr
 ess at UW-Madison towards addressing these needs.
