Advances in our ability to study and exploit the properties of atoms for measurements of physical quantities has ushered in a new age of technological possibilities in quantum sensing and measurement. Seminal developments include atomic clocks, atomic magnetometers, and inertial sensors based on atom interferometry. This lecture will introduce the advent of new quantum technologies for sensing and measurements of electric fields based on using exquisitely sensitive and versatile atoms in highly-excited Rydberg states. Dr. Anderson will describe the new atomic sensor technologies under development at Rydberg Technologies LLC, from basic measurement principles to applications in metrology, RF engineering, and plasma science.
