Denmark is creating the world’s most powerful quantum computer “Magne” with Microsoft’s support

Denmark is making an ambitious move in the global quantum race by announcing the development of the world’s most powerful quantum computer, named “Magne.” The project, known as QuNorth, is being implemented with the participation of Microsoft and California-based Atom Computing, and is backed by €80 million in funding from the Danish Export and Investment Fund (EIFO) and the Novo Nordisk Foundation, according to Bundle. The computer, which will be located in Copenhagen, is set to become the first “Level 2” quantum computer in Scandinavia, capable of performing complex computations with error correction—making it a potential leader in quantum technology.

Technical Specifications of “Magne”

The “Magne” quantum computer, named after the son of the Norse god Thor, will operate with 50 logical qubits and more than 1,200 physical qubits, placing it among the most advanced devices in the world. For comparison, Atom Computing currently holds the record for the number of physical qubits (1,180), while Quantinuum leads with 50 logical qubits. “Magne” will be the first machine to combine both achievements, significantly enhancing the reliability and performance of quantum computations.

• Physical qubits are the basic units of quantum information, but they are unstable and prone to errors.
• Logical qubits are virtual units made up of multiple physical qubits and provide stability through quantum error correction.

Microsoft will provide software based on its Azure Quantum stack, optimized for Atom Computing’s “neutral atom” technology. This technology, which uses atoms held in place by lasers, is considered one of the most promising in the field of quantum computing. “Magne” will be a fully integrated system, including hardware, algorithms, an operating system, a compiler, and control electronics.

The Significance of the QuNorth Project

QuNorth is aimed at strengthening Denmark’s and the broader Nordic region’s position in the global quantum race. “Quantum technologies hold enormous potential, and Denmark, together with the EU, must seize this opportunity,” said Danish Minister for Business Morten Bødskov. He emphasized that the investment in “Magne” is a “serious leap forward” that will benefit not only Denmark but all of Europe.

“Magne” will be the first commercially available “Level 2” quantum computer capable of performing complex calculations with high reliability, thanks to built-in error correction. This opens the door for breakthroughs in areas such as drug development, chemical compound modeling, and climate research. According to Microsoft Executive Vice President Jason Zander, 50 logical qubits is the threshold at which “quantum advantage” begins—allowing problems that are beyond the reach of classical computers to be solved. At 100 qubits, scientific challenges could be tackled, and at 1,000 qubits, “virtually anything” could be solved.

Implementation and Timeline

Construction of “Magne” will begin in the fall of 2025, with the system scheduled to launch between late 2026 and early 2027. The computer will be located in Copenhagen and be 100% Danish-owned, with EIFO and the Novo Nordisk Foundation each investing about €40 million and holding equal shares. QuNorth will also establish a small team of around 10 employees and is currently searching for a CEO to lead the project.

To support academic and commercial users, QuNorth will collaborate with regional universities and companies, providing access to “Magne” for research in materials science, chemistry, and pharmaceuticals. This is especially important for the Novo Nordisk Foundation, which sees quantum computing as a tool for developing new medicines and modeling complex biological systems.

The Role of Microsoft and Atom Computing

Microsoft—whose largest quantum research lab is in Denmark—will supply software through its Azure Quantum platform, adapted for Atom Computing’s neutral atom technology. In November 2024, the companies reached a record of 24 logical qubits, marking an important milestone in quantum technology development. Atom Computing, for its part, will provide the hardware, based on neutral atom technology, known for its high qubit stability. The company has already opened its European headquarters in Copenhagen, strengthening its ties with Denmark’s quantum research ecosystem.

Geopolitical and Scientific Context

QuNorth is not only a technological endeavor but also a strategic move. Denmark aims to strengthen its position at a time when the U.S. and China are heavily investing in quantum technologies. Europe’s lack of access to advanced quantum systems has put it at a disadvantage, and “Magne” aims to change that by creating a center for quantum innovation in Scandinavia.

Moreover, hosting “Magne” in Denmark ensures data security, as all information will remain within the region. This is particularly important for research in sensitive areas such as pharmaceuticals and national security. The project also aligns with Denmark’s national quantum strategy, under which the government will invest 1 billion Danish kroner (about €130 million) in quantum research and innovation from 2023 to 2027.

Conclusion

The “Magne” project and the QuNorth initiative place Denmark at the center of the global quantum race. The creation of the world’s most powerful quantum computer—with 50 logical and more than 1,200 physical qubits—opens new opportunities for scientific and commercial breakthroughs. With support from Microsoft and Atom Computing, and backing from EIFO and the Novo Nordisk Foundation, Denmark is not only enhancing its technological independence but also building a platform for innovation in pharmaceuticals, materials science, and climate research. The launch of “Magne” in 2026–2027 will mark a key milestone on the path to quantum advantage and strengthen Scandinavia’s position on the global stage.
