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, including magnetometry and inertial sensing. In this talk, I will describe the realization of quantum sensors in two material systems: neutral alkali atoms and color centers in diamond. These platforms have complementary properties that make each uniquely advantageous for certain sensing applications, as well as challenges that currently limit their sensing performance and functionality. I will discuss various approaches to improve the sensing performance and utility of atomic and solid-state quantum sensors, using photonic design and integration, materials engineering, and algorithms development.
