Alice & Bob is building the first universal, fault-tolerant quantum computer to tackle civilization-defining challenges. Founded in 2020 and headquartered in Paris with a growing presence in Boston, the company has emerged as a leader in quantum computing, securing €130 million in funding to advance its groundbreaking technology. Alice & Bob specializes in Bosonic codes and self-correcting superconducting quantum processors, with a core innovation being the 'cat qubit' - a novel type of superconducting qubit with the remarkable ability to implement quantum error correction autonomously.
The company approach dramatically reduces the qubit count required for fault-tolerant quantum computing - potentially needing up to 200x fewer qubits than competing technologies. Today, Alice & Bob employs over 140 brilliant minds from more than 20 countries, competing directly with tech giants like Google and IBM in the race to deliver practical quantum computing. The company has published a detailed roadmap outlining five key milestones to deliver a universal, fault-tolerant quantum computer by 2030. Their technology targets transformative applications in drug discovery, molecular simulation, cryptography, and optimization problems that classical computers cannot solve.
