Jun Ye (Chinese: 叶军; pinyin: Yè Jūn; born 1967) is a Chinese-American physicist at JILA, National Institute of Standards and Technology, and the University of Colorado Boulder, working primarily in the field of atomic, molecular, and optical physics.

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.

[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).

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.
