Quantum Sensing and Timing at AFRL

Thursday December 7, 2023
3:30 pm

 Presenter:  Brian Kasch (Air Force Research Lab)
 Series:  CQuIC Seminars
 Abstract:  AFRL's Quantum Sensing and Timing (QST) group looks into the development of advanced atomic clocks to further improve time measurements and investigates ways to use and distribute the precise time. Our team is developing the next generation of clocks with enhanced stability and techniques to transmit time synchronization precisely across distant platforms. Precise timekeeping is the backbone of modern telecommunications, banking technologies, and navigation systems. The most stable and precise clocks on the planet can keep time without losing a single second over the age of the universe. However, advanced quantum clocks are often large and power hungry, which has kept them confined to laboratory environments. We are developing technologies that will reduce the size and complexity of advanced clocks while also refining techniques to more accurately transfer time in real-world environments.

Additionally, we seek to take advantage of Nobel-Prize winning cold-atoms physics and related techniques to develop solutions for critical DoD problems in positioning, navigation and timing. Ultracold atoms offer excellent sensory information about the magnetic, electric, inertial, and gravitational environments within which the atoms reside. As such, quantum sensors based on ultracold atoms have the potential to significantly impact a variety of military and civilian applications.

Photonic integrated circuits (PICs) will play a key role in transitioning quantum-enabled technologies beyond the laboratory. While photonic components in the telecommunication bands are relatively commonplace, the infrastructure supporting other wavelengths is relatively lacking. To advance this technology, our team investigates novel photonic components including microcombs and PIC-compatible laser sources.

The QST group seeks to develop compact quantum systems that allow transition into real-world applications.
