Ye was born in Shanghai, China, shortly after the beginning of the Cultural Revolution. His father was a naval officer and his mother an environmental scientist. He was primarily raised by his grandmother.[1] Ye graduated with a bachelor's degree in physics from Shanghai Jiao Tong University in 1989. He then moved to the United States to commence graduate studies, completing a master's degree at the University of New Mexico under Marlan Scully in theoretical quantum optics in 1991. He also gained experience in experimental physics under John McInerney working on semiconductor lasers, and spent a summer at the Los Alamos National Laboratory.[1]
Ye then went to the University of Colorado Boulder to begin a Ph.D. in physics. He was accepted as the last graduate student of eventual Nobel Prize laureate John L. Hall. His thesis was on high-resolution and high-sensitivity molecular spectroscopy, which he completed in 1997.[2] He then moved to California Institute of Technology as a Milikan Postdoctoral Fellow, working under Jeff Kimble.[3]
Ye moved back to Boulder and JILA as a JILA Associate Fellow and NIST physicist in 1999. John Hall donated most of his lab space to him.[1] He was promoted to full Fellow in 2001 and has been there since, establishing a research program in AMO physics and precision measurement.[4]
Ye's research focuses on ultracold atoms, ultracold molecules, and laser-based precision measurement. In 2018 JILA reported that the 3D quantum gas clock reached a frequency precision of 2.5 × 10−19 over 6 hours.[5]
Such clocks could potentially be used for research into variations in the Earth's gravitational field, searching for particles of dark matter, performing quantum simulations of many-body physics, and investigating the fundamental nature of light and matter.[6][7] He also conducts research on strontium for experiments in quantum information science (collaborating with Mikhail Lukin, Ana Maria Rey, Peter Zoller, and others).[8]
Ye appeared in the 2018 Netflix documentary The Most Unknown[9] on scientific research directed by Ian Cheney.
Ye has received numerous awards in the field of science, particularly AMO physics. These include:
In 2015, President Obama selected Jun Ye to receive a Presidential Rank Award for “sustained extraordinary accomplishment”, citing his work advancing "the frontier of light-matter interaction and focusing on precision measurement, quantum physics and ultracold matter, optical frequency metrology, and ultrafast science."[24] He was elected a Fellow of the American Physical Society[25] and a Fellow of the Optical Society of America. In 2011 he was elected to the National Academy of Sciences,[26] and also named a Frew Fellow from the Australian Academy of Science. In 2017, Ye was elected as a foreign member of the Chinese Academy of Sciences.[27]
He is one of the most highly cited researchers in experimental atomic physics in the world, having according to Google Scholar a h-index of 120 (As of 2022[update])[28] and being regularly named as a Thomson-Reuters (ISI) Highly Cited Researcher.[29]
Ye also holds four U.S. Patents for frequency combs and laser technology.
