This event has been rescheduled for January 30, 2024. Atomic clocks are the silent heartbeat that operate quietly in the background for everything from data centers, to GPS, to financial trading, to cell phone networks and air traffic control. At the core of each clock are atoms, ions, or molecules, that transition between quantum states when bombarded with photons in the form of light or microwaves. In this webinar we will discuss the quantum principles involved, how they affect the clock stabilities, and recent advances in clock technology. dinner(fee): 6:30pm.
