On November 12, 2025, Microsoft announced the expansion of its quantum computing facility in Lyngby, Denmark, making it the company’s largest quantum site globally. Total Microsoft quantum investments in Denmark have now surpassed DKK 1 billion, according to a Microsoft blog post. The original Lyngby lab, opened in 2018, was the first facility in the world dedicated to building the qubit core for topological quantum computing.
With the expansion, the Lyngby facility can now fabricate the full core of Microsoft’s Majorana 1 quantum processing unit, which was partly developed in Denmark. The Majorana 1, introduced earlier in 2025, is designed to scale to millions of qubits on a single chip using topological qubits. The lab houses physicists, material scientists, nanofabrication experts, and software engineers representing more than 20 nationalities.
Vice President Lauri Sainiemi said the facility gives teams “the cleanroom capacity, instrumentation, and process control needed to iterate faster.” Microsoft described the expansion as aligned with the European Commission’s Quantum Europe Strategy and its broader commitment to European quantum infrastructure.
