Bluefors, headquartered in Helsinki, makes ultra-low temperature cryogenic systems needed to keep qubits stable. Its systems are essential for both research and industrial quantum computers.
Bluefors has expanded globally, including in the USA, and launched a Lab-as-a-Service model, giving companies access to advanced cooling technology without full ownership.
Quanscient – Cloud-Native Quantum Simulation
Quanscient builds a cloud-based quantum simulation platform for engineering. Its platform integrates multiphysics solvers, advanced cloud computing, and quantum algorithms. It allows engineers to run simulations up to 100 times faster than traditional tools.
Quanscient raised €5.2 million in 2024 and became the first company to run Computational Fluid Dynamics (CFD) simulations on real quantum hardware.
Other Startups and Ecosystem Players
Finland’s BusinessQ community now includes over 25 companies working across the quantum value chain, such as Arctic Instruments and SemiQon spin-offs.
Together, they form a robust quantum ecosystem supporting research, commercial applications, and international collaboration.
Integration with Supercomputers
Quantum computers do not replace traditional supercomputers. Instead, they work together. A quantum computer handles problems suitable for quantum methods, while a supercomputer manages control, interpretation, and classical calculations. This combination creates quantum-accelerated high-performance computing.
In Finland, the LUMI supercomputer and VTT’s Helmi/50-qubit quantum computer were integrated in 2022. This was the first time in Europe that a universal quantum computer connected to a supercomputer was available to researchers. Scientists and businesses can access these systems through proposals submitted to the LUMI supercomputer.
Finland is also involved in international collaborations, including:
- FiQCI: Finnish Quantum Computing Infrastructure
- NordIQuEst: Developing Nordic quantum computing capabilities
- OpenSuperQ+: 28 European partners working on a 1,000-qubit quantum computer.
Quantum computing and AI
Quantum computing has the potential to transform artificial intelligence by dramatically speeding up data processing and complex computations. By leveraging qubits and quantum algorithms, AI models can be trained faster, optimized more efficiently, and handle problems that are too large or complex for classical computers.
In Finland, researchers and startups are exploring how quantum-enhanced AI can improve applications in drug discovery, materials science, finance, and advanced simulations, creating new opportunities for innovation across industries.
