Abstract: 

The discrete electronic energy levels in atoms and the ability to probe and control them using their interactions with electromagnetic fields have enabled a host of applications in quantum sensing and metrology, including atom-based time and frequency standards, magnetometers, and inertial sensors. Precision measurements with atoms rely 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 critical to advancing state-of-the-art atomic sensors. In this talk, I will summarize the basic principles of atom-based quantum sensing and highlight the role of atom-photon interactions in quantum measurements. The benefits and challenges of realizing atom-based quantum sensors will be illustrated through examples from my prior research, including the development of sensitive accelerometers and gyroscopes based on cold-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 progress at UW-Madison towards addressing these needs.
