IonQ has appointed Katie Arrington as Chief Information Officer and Leslie Kershaw as Chief Information Security Officer, effective January 19, 2026. Arrington, formerly the CIO of the U.S. Department of Defense, will enhance the company's cybersecurity and operational resilience, while Kershaw will report to her. Despite IonQ's advancements in quantum computing and a projected 151% revenue growth for the fiscal year, analysts view the company as overvalued.
