Chin-wen (James) Chou is a staff scientist in the Ion Storage Group at the National Institute of Standards and Technology and Lecturer at the University of Colorado, Boulder. Throughout his career, he has worked in the fields of quantum information and precision measurements including atomic ensemble-based quantum communication, neutral atom quantum registers, and Al+ ion optical clocks. He is currently working on advancing both fronts for molecular ions, using the tools developed in quantum information for precision measurements and vice versa. He received his Ph.D. in physics from the California Institute of Technology in 2006. After his postdoctoral studies at NIST and a staff position at Sandia National Laboratories, he re-joined the Ion Storage Group in the Time and Frequency Division of NIST, Boulder in 2013.
