We’re building the world’s best quantum computers to solve the world’s hardest problems

We believe useful quantum computers will look as different from the laptops and smartphones we use every day as classical computers appear next to an abacus. And we believe the best way to build a quantum computer is by starting with nature’s qubit: the atom. Accurate, powerful, and flexible, ionized atoms are the heart of our quantum systems.

After decades of research, IonQ was founded in 2015 by Chris Monroe and Jungsang Kim with $2 million in seed funding from New Enterprise Associates, a license to core technology from the University of Maryland and Duke University, and the goal of taking trapped ion quantum computing out of the lab and into the market. The next year, we raised an additional $20 million from GV, Amazon Web Services, and NEA, and built two of the world’s most accurate quantum computers.

In 2019, we raised another $55 million in a round led by Samsung and Mubadala, and announced partnerships with Microsoft and Amazon Web Services to make our quantum computers available via the cloud. We’re now hard at work bringing our next generation of hardware to life and to partners around the world.
