Objective: Quantum computers could completely revolutionise the world. A successful quantum computer could perform simulations that would take billions of years on the most powerful supercomputer in a matter of minutes. But first, there is a critical challenge to overcome. Current quantum computers are error-prone and incapable of executing complex algorithms reliably. Eliminating these quantum errors is the main challenge in quantum computing. We have invented a new type of self-correcting quantum hardware—the Schrödinger cat quantum bits (qubits). Using self-correction, we will be able to build the world's first fault-tolerant commercial quantum computers a decade earlier than our competitors. Quantum computing is a technology of the highest strategic importance. Today, American tech giants are ahead, but who will lead the quantum revolution is not decided yet. With self-correcting cat qubits, we can take the lead and ensure the next generation of information technologies are European.
