CU Physics Professor Jun Ye is Awarded the Monroe Endowed Professorship
Jun Ye, a professor of physics and a JILA and NIST Fellow, has been named the inaugural holder of the Monroe Endowed Professorship in Physics. This prestigious new professorship, the result of a $1 million endowment from CU alumnus Chris Monroe, underscores the university’s growing prominence in quantum information science and applied quantum physics.
“I went to CU for graduate school simply because it looked like the best place for me to study atomic and quantum physics,” Monroe said. “Only later did I realize just how much better it was than high-drama places on the coasts. I cannot imagine a better preparation for the rest of my career having gone through CU and JILA.”
Chris Monroe, Circa 1990
Monroe, a pioneering physicist and co-founder of IonQ, Inc., established the Monroe Endowed Professorship in Physics to support CU Boulder’s leadership in the rapidly evolving field of quantum research. He graduated from CU Boulder in 1992 with a Ph.D. in Physics under the mentorship of Nobel Laureates Carl Wieman and Eric Cornell, then worked closely with Nobel Laureate David Wineland at nearby NIST-Boulder as they pioneered the use of individual atoms as quantum computer bits (qubits). His illustrious career has taken him to Duke University, where he is the Director of the Duke Quantum Center, and holds the Gilhuly Family Presidential Distinguished Professor of Electrical and Computer Engineering and Physics at Duke. Monroe’s research has pioneered all aspects in designing and fabricating scalable quantum computers based on atomic qubits. His machines have been programmed for rudimentary quantum algorithms and simulations of complex quantum phenomena in nature. His company IonQ, the first public quantum computing company, aims to commercialize quantum computers according to a clear technology roadmap.
His vision for the CU Physics endowment, outlined in the fund agreement, is clear: “The purpose in establishing this Fund is to enable the University and JILA to expand its research and education capacity in quantum information science and applied quantum physics through an endowed professorship position that will retain current faculty or allow the University and JILA to hire the best and brightest researchers in this field.”
One of the leaders teaching the best and brightest researchers is Jun Ye, who is internationally recognized for his groundbreaking work in precision measurement, ultracold molecules, and ultra-high precision atomic clocks. His strontium lattice atomic clock, which uses laser-based technology, is currently the most accurate in the world. His very recent measurement of a nuclear transition using laser light could revolutionize clocks (and maybe even quantum computers) well into the future. Ye’s numerous accolades reflect his leadership in the field, including the 2022 Breakthrough Prize, the I.I. Rabi Prize, and the Niels Bohr Institute Medal of Honor.
“I certainly feel very honored to be a recipient of the Monroe Endowed Professorship,” Ye said. “I have known Chris for many years. It turns out that when I arrived in JILA and CU Physics as a fresh graduate student, the very first PhD defense I witnessed was Chris's work with Carl Wieman. I have regarded Chris a gold standard for JILA and CU Physics graduates ever since. He has made big impact to quantum information science, being an original practitioner, a visionary advocate, and a breakthrough technologist.”
The selection committee, led by CU Boulder Physics Professor Paul Beale and including a combination of Physics department faculty and JILA Fellows, unanimously chose Ye for the position
“Jun is internationally recognized as a leader in quantum science and technology with a specialty in precision measurement,” Beale said in a statement from the selection committee. “He is a world leader in frequency combs, ultracold molecules, and ultra-high precision atomic clocks,”
The Monroe Endowed Professorship joins a distinguished lineage of other endowed positions in CU Boulder’s Department of Physics. In 2021, alumnus Joseph Mitchell and his wife Cindy established the Jesse Lafayette Mitchell Endowed Chair in Experimental Physics. Alysia Marino currently holds this chair, where her research focuses on neutrino detection and the fundamental properties of these elusive particles. Additionally, the Waldo E. Rennie Endowed Professorship in Theoretical Physics, created in 2021 with funds from the trust of Waldo E. Rennie, supports Michael Hermele’s research in quantum phases of matter and strongly correlated systems.
As the holder of the new Monroe Endowed Professorship, Jun Ye is poised to continue his transformative work in quantum physics, ensuring that CU Boulder remains at the forefront of quantum science research.
“I will continue to draw inspiration from Chris and help to advance the field of quantum science and precision measurement,” added Ye.
