Executive management

Peter Chapman is President and CEO of IonQ and a Member of the Board. Prior to joining IonQ, Mr. Chapman was Director of Engineering for Amazon Prime, where he led the team responsible for Prime’s 2-Day delivery. He has over 40 years of leadership in software engineering, including alongside luminaries like Marvin Minsky and Ray Kurzweil. Mr. Chapman is credited with inventing the original sound card for computers, writing the software the Federal Aviation Administration uses to prevent mid-air collisions, and developing systems that protect the integrity of financial markets. Mr. Chapman has founded and led several companies to successful exits. He has served as IonQ’s president and chief executive officer and a member of its board of directors since May 2019.

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.

Thomas Kramer is the Chief Financial Officer at IonQ. Mr. Kramer is an experienced Chief Financial Officer with an extensive background leading companies through rapid growth. At IonQ, Mr. Kramer focuses on commercializing our infrastructure and managing the company's relationships with investors and the public markets. He sits on the boards of PerfectServe, Peak Dental Systems, and MindsMatter DC. Previously, Mr. Kramer was the CFO of Opower, where he guided the company through its initial public offering and its sale later to Oracle; and co-founder and CFO of Cvent, where he took the company from zero revenue through the largest private software financing in the United States at that time. Mr. Kramer has served as IonQ’s Chief Financial Officer since February 2021.

Chris Monroe is Chief Scientist at IonQ. Dr. Monroe is a world-renowned pioneer in quantum physics and the original inventor of the ion trap quantum computer. With David Wineland, he demonstrated the first quantum logic gate in 1995 at NIST, which contributed to Wineland’s Nobel Prize in 2012. Later, at the Universities of Michigan and Maryland, Dr. Monroe demonstrated the first ion trap on a semiconductor chip, pioneered qubit networking using photons, and developed ultrafast quantum gates for trapped ion qubits. He is a Professor of Physics and Electrical Computer Engineering at Duke University and a College Park Professor at the University of Maryland. Dr. Monroe is also a member of the National Academy of Sciences and the National Quantum Initiative Advisory Committee. Dr. Monroe is IonQ’s co-founder and has served as its chief scientist since September 2015.
