    The discrete electronic energy levels in atoms and atom-like systems 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. In this talk, I will describe the realization of quantum sensors in two material platforms: cooled neutral atoms and artificial atoms found in wide-bandgap semiconductors. The benefits and challenges of these platforms will be illustrated through examples from my prior research, including the development of sensitive accelerometers and gyroscopes based on cold-atom interferometers, and the engineering of the optical properties of color centers in diamond for applications in magnetometry and quantum information science. I will discuss the critical developments in photonic engineering and material science that are needed to improve device utility and performance in atomic and solid-state quantum sensors and our research progress at UW-Madison towards addressing these needs.
