Atomic Clocks: The Original Qubit

Dr. Chen is currently a postdoctoral research associate in the Time and Frequency Division at the National Institute of Standards and Technology (NIST). Before starting his graduate school studies, he spent three months at the Institute for Quantum Optics and Quantum Information (IQOQI, Innsbruck), institute of the Austrian Academy of Sciences, as a visiting researcher. He later obtained his Ph.D. degree in experimental physics from the University of Amsterdam, Netherlands, in 2019. His main research interests include development of a continuous-wave atom laser (a matter-wave equivalent of a CW optical laser), optical atomic clocks for quantum metrology, ultrastable optical sources, and the application of these systems to fundamental physics studies and advanced technology.


Quantum systems built from atoms have been the very-first qubits in history but in the meantime at the forefront of contemporary quantum technology development, due to their exceptional environmental isolation and our ability to manipulate these systems with exquisite fidelity using light.  This is exemplified in atomic clocks, systems which keep time with a precision better than half a second over the age of the universe. These same strengths make them outstanding quantum computing platforms, where the nature-given long coherence times (T1) are available in an atomic clock qubit. In this talk, I will highlight challenges and opportunities in ion and neutral-atom qubit platforms and will present recent advances and future prospects in atom quantum computing.
