Qolumbus is a French deep-tech startup developing a new generation of hybrid quantum processors combining superconducting qubits and semiconductor spins. Our unique architecture aims to overcome the key limitations of current quantum technologies by enabling higher fidelity, scalability and more efficient error correction.

Built on more than a decade of research and strong partnerships with leading European laboratories and industrial players, Qolumbus focuses on accelerating the transition from experimental quantum systems to reliable, industrial-grade quantum computing.

We design hybrid quantum chips, provide cloud-based quantum access (QaaS), and support industrial co-development programs to unlock real-world applications in material chemical, energy, materials, finance and defense.

Our mission is to contribute to a sovereign, sustainable and energy-efficient quantum ecosystem in Europe
