On October 14, the IBM Quantum System Two—currently the most powerful quantum computer in Europe—began operating in Donostia–San Sebastián. Beyond the technological milestone, its relevance lies in what it enables: access to a new kind of computing designed to tackle problems that are too complex for today’s supercomputers.
Quantum computing is not meant to replace today’s computers. Instead, it offers specialized tools that could make a difference in fields where classical computing is reaching its limits. These are some examples:
First, simulating molecules is one of the hardest tasks in computing. Research demonstrated that quantum algorithms can reproduce molecular energies with accuracy far beyond classical methods. This could accelerate the search for new drugs and more personalized treatments.
Second, many modern materials—like better batteries, new superconductors or faster catalysts—depend on tiny quantum effects that are very hard to calculate with normal computers. Research shows that quantum algorithms could help scientists predict how these materials will behave before they are built. This means new materials could be designed faster, more cheaply, and with better performance for clean-energy technologies.
Third, climate models are extremely complex because they include thousands of connected factors, like temperature, wind, oceans and greenhouse gases. Studies suggest that quantum artificial intelligence could make it easier to predict extreme weather events and understand how the climate is changing.
Therefore, the IBM Quantum System Two in Donostia brings state-of-the-art quantum hardware to Europe. It gives researchers, students, laboratories and companies a chance to work directly with a real quantum processor instead of relying on theoretical models alone. This accelerates hands-on experimentation, talent development and innovation. It is not only a scientific achievement but also an opportunity to develop solutions for health, energy, industry and climate challenges using a tool that explores nature at its most fundamental level.
