Practical Atom-Based Quantum Sensors

Abstract: Atomic vapors, manipulated and probed by light and other electromagnetic fields, constitute versatile and powerful quantum systems for sensing applications. Atoms are identical, isolatable, interfaceable, and intelligible. These features, coupled with the relative simplicity with which quantum properties can be exploited in state preparation and detection using modern laser and electro-optic tools, make atoms very attractive for sensing applications. This talk will highlight aspects of a recently published Perspective in Physical Review A focusing on using atomic vapors for ‘practical’ quantum sensors—defined here as sensors that have been stripped to their bare essentials, made compact and inexpensive, and designed for use by non-specialists in uncontrolled environments, all while retaining as much as possible of their ideal performance. Examples of the contributions of a non-profit company like Draper to the quantum ecosystem, transitioning fundamental science with light and atoms into practical sensors, will be given.

Dr. Justin M. Brown

Bio: Dr. Justin M. Brown is currently Principal Member Technical Staff at the Draper Laboratory located in Cambridge, MA and focuses on atom-based quantum sensors and their practical applications. His atomic physics experience spans spin-based measurements in warm vapor cells as magnetometers or gyroscopes to atom interferometer measurements using laser-cooled atoms as inertial sensors. Over the last decade, he has contributed to or led multiple sponsored research efforts to advance novel atom-based sensors and their supporting technology. Previous roles include Principal Research Scientist at Physical Sciences Inc. as well as an academic research professor at the University of Southern California Information Sciences Institute. He has served on the American Physical Society Committee on Careers and Professional Development as well as on his local municipal planning board. Dr. Brown received a PhD in Physics from Princeton University and was awarded the Miller Postdoctoral Fellowship at the University of California Berkeley.

This speaker is hosted by Associate Professor Jennifer Choy .
