IQM Quantum Computers has launched Halocene, a new quantum computing product line focused on error correction development.

Based on an open and modular error correction stack, the Halocene portfolio will comprise a 150-qubit system set to be commercially available by the end of 2026, extending to a 1,000+ qubit system to be released at an unknown later date.

In a statement, IQM said the release schedule aligns with the company’s product roadmap, which outlines a path to achieving fault-tolerant quantum computing by 2030.

The Halocene portfolio builds on IQM’s Radiance product line, with the initial 150-qubit system comprising an IQM Crystal quantum processing unit (QPU), which targets a 99.7 percent physical two-qubit gate fidelity and additional error correction features.

Halocene will also support the execution of Noisy Intermediate Scale (NISQ) algorithms and the development of error mitigation techniques, the company said.

“Halocene is the result of co-developing our technology stack with our partners and customers as we build a thriving quantum ecosystem together,” said Jan Goetz, co-CEO of IQM Quantum Computers. “With this launch, we are shaping the next frontier in error-corrected quantum computing, transforming research into technologies that will drive industrial innovation and economic growth. Our goal is to give our users the best-in-class performance and system-level control to solve complex problems.”

Founded in Helsinki, Finland, in 2018, IQM brings full-stack quantum computers and applications to HPCs, research institutes, universities, and business enterprises. The company operates quantum data centers in Finland and Munich, Germany, offering cloud-based access to its systems. It has delivered quantum systems to supercomputing centers in South Korea, Poland, Italy, and Taiwan.

In September 2025, IQM raised more than $300 million in the largest Series B raise achieved in the quantum space outside of the US.
