IQM Quantum Computers has installed a 20-qubit IQM Radiance quantum computer at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee, marking the Finnish company's first deployment on U.S. soil and ORNL's first commercially procured quantum computer.

The system, named Pathfinder, is connected to high-performance computing (HPC) systems in the National Center for Computational Sciences Technology Integration Group's test bed. ORNL owns and operates the system directly on its campus, consistent with IQM's on-premises deployment model, which gives customers ownership of both the hardware and any intellectual property developed on it.

ORNL researchers plan to use Pathfinder to develop methods and tools for a hybrid quantum-HPC ecosystem, with applications targeted in materials simulations, chemistry, and artificial intelligence, according to ORNL Quantum Science Center Director Travis Humble.

"On-premises systems enable us to demonstrate quantum computing concepts that realize our goal of building a scalable, hybrid HPC ecosystem," Humble said in a statement.

IQM states it has sold 23 full-stack quantum systems globally, claiming more on-premises installations than any other manufacturer. The company is headquartered in Espoo, Finland, and has over 400 employees.

The deployment coincides with IQM's planned listing on the Nasdaq Global Select Market through a business combination with Real Asset Acquisition Corp. (Nasdaq: RAAQ), expected to close in mid-2026. IQM also recently opened a U.S. Quantum Technology Center in the Discovery District, Maryland.
