Jungsang Kim is Chief Technology Officer of IonQ and a Member of the Board. Dr. Kim is regarded as one of the leading quantum computer engineers of our time. Prior to co-founding IonQ, Dr. Kim developed the first semiconductor based on a single photon source. During his five-year tenure at Bell Labs, Dr. Kim led the team that built the world’s largest optical switch, a record that still stands 20 years later. In 2004 he joined the faculty at Duke University, where he has relentlessly pursued technical innovations that pave the path towards practical quantum computers using trapped ion technology. Together, Dr. Kim and IonQ Co-Founder, Dr. Chris Monroe, invented the scalable quantum computer architecture using trapped ions that powers IonQ. Dr. Kim is a Professor of Electrical and Computer Engineering, Physics, and Computer Science at Duke University and a member of the National Quantum Initiative Advisory Committee. Dr. Kim is IonQ’s co-founder and has served as its Chief Strategy Officer and a member of its board of directors since September 2015. He assumed the role of Chief Technology Officer in 2020.
