WHY INCLUDED

An executive whose quantum-sector contribution centers on IonQ’s public-market transition and corporate leadership, connecting technology development with financing, partnerships and organizational execution.

IonQIonQ

De Masi belongs in this edition for a business-building role rather than a claimed scientific invention. He led the special-purpose acquisition company involved in IonQ’s public listing and subsequently became IonQ’s chief executive and chairman. These are consequential organizational positions in a capital-intensive field. His profile therefore focuses on documented transaction and leadership responsibilities, while the design and performance of IonQ hardware remain achievements attributable to the company’s research and engineering teams.
