It’s not just a tour; it’s an initiative to democratize science, making what once seemed confined to elite labs accessible to all. “This route doesn’t just connect buildings, but ideas that change the world,” stated a Basque Quantum representative during the launch, emphasizing how Donostia is becoming a beacon of progress in the quantum era.
At a time when searches for “quantum innovation in Spain” and “scientific tours in San Sebastian 2025” are surging, this comprehensive guide will take you step by step along the route, explain key concepts simply, and reveal why now, in November 2025, is the perfect time to visit. Whether you’re seeking a physical experience under the autumnal Basque sun or a virtual tour from your couch, the Quantum Mile offers something for everyone. Get ready to discover how one mile can stretch the boundaries of possibility.
The Origins of the Quantum Mile in San Sebastian: From Theory to Reality in Donostia
The story of the Quantum Mile traces back to the growing concentration of scientific talent in the Basque Country. Since the 2010s, institutions like the Donostia International Physics Center (DIPC) and CIC nanoGUNE have attracted researchers from around the globe, turning Ibaeta into one of Europe’s most active hubs for quantum physics. But the real catalyst came in 2025 with the installation of the IBM Quantum System Two in the Ikerbasque building—the first in Europe and the third worldwide. This quantum supercomputer, capable of processing molecular simulations for new drugs or advanced AI algorithms, has elevated San Sebastian’s profile to international levels.
The project, backed by Basque Quantum—a strategic alliance to coordinate quantum research in Euskadi—aims not only to foster collaboration among centers but also to educate the public. At the inauguration, Basque Government Education Councilor Jone Berriozabal remarked: “The Quantum Mile is a bridge between science and society, showing how innovation drives economic and social development.” In a year marked by the quantum centenary, this route arrives at an opportune moment, coinciding with global events celebrating the breakthroughs of Heisenberg and Schrödinger. For Donostia, it signifies a step forward in its transformation from a gastronomic tourist destination to a scientific tourism pole, attracting visitors who pair pintxos with subatomic particles.
Exploring the Route: A Detailed Walk Through the Seven Innovation Centers
The Quantum Mile is a marked path of about 1.5 kilometers, ideal for a 30- to 45-minute walk. It starts at the Ikerbasque building and winds through the UPV/EHU’s Gipuzkoa campus, featuring trilingual informational panels (Basque, Spanish, and English) illustrated by local female scientists. Each stop includes QR codes linking to interactive content, such as explanatory videos or virtual simulations.
Here’s a breakdown of the seven key stops:
- Faculty of Informatics (UPV/EHU): Focused on quantum algorithms and programming. Learn how qubits—the basic units of quantum computing—outperform traditional bits, solving complex problems in seconds.
- Faculty of Chemistry (UPV/EHU): Explores applications in quantum chemistry, like designing materials for more efficient batteries or catalysts for renewable energy. An interactive panel simulates molecular reactions at the quantum level.
- Donostia International Physics Center (DIPC): Home to the Hyperion supercomputer, this center investigates quantum phenomena in condensed matter. It highlights its role in simulating quantum universes, with infographics on quantum entanglement.
- Center for Materials Physics (CFM): Specialized in quantum materials, such as superconductors operating at room temperature. Perfect for understanding how these advances could revolutionize energy transmission.
- CIC nanoGUNE: A nanotechnology lab with “clean rooms” for atom manipulation. The stop includes virtual views of electron microscopes and projects in quantum detection, like sensors for AI.
- Tecnun (University of Navarra): Contributes with applied engineering, integrating quantum tech into robotics and intelligent systems. A practical approach showcasing real-world industry applications.
- Ikerbasque Building (Basque Quantum): The climax, featuring the IBM Quantum System Two. Here, panels explain its power: processing data that a classical computer would take millennia to handle.
To get there, take bus lines 5 or 24 from central Donostia. It’s accessible to all, with ramps and bike options. In November, with the autumn weather, it’s ideal for a thoughtful stroll.
Quantum Concepts Explained: From Superposition to Technological Future
Quantum physics can sound daunting, but the Mile demystifies it with accessible explanations. At its core, it studies subatomic particles where strange rules apply: superposition, where an electron can be in multiple states at once, like a spinning coin that’s both heads and tails; entanglement, particles instantly connected regardless of distance, the basis for ultra-secure communications; and quantum tunneling, allowing “passage” through impossible barriers, honored in the 2025 Nobel.
In Donostia, these principles are put into practice. The IBM Quantum System Two, for instance, uses qubits to model complex molecules, speeding up discoveries for cancer drugs or sustainable batteries. “Quantum isn’t science fiction; it’s the key to solving global challenges,” says a DIPC researcher in a route video. For the average visitor, simple analogies—like comparing qubits to human multitasking—make it relatable, appealing even to families and students.
The Virtual Experience: Access Labs from Anywhere
If a physical trip isn’t feasible, the virtual version is just as immersive. Through quantummile.basquequantum.eus, explore 360-degree labs like nanoGUNE’s Clean Room, where nanostructures are built, or recreations of the IBM Quantum. It includes educational audios and interactive quizzes, perfect for educators. In November 2025, updates feature modules on the quantum centenary, making it a global teaching tool.
