Alice & Bob is a pioneering French quantum computing startup that has developed a revolutionary approach to quantum error correction using ‘cat qubits’ - a breakthrough technology that significantly reduces the overhead required for fault-tolerant quantum computing. Founded in 2020 by Théau Peronnin, Raphaël Lescanne, and other researchers from École Normale Supérieure and INRIA, the company has created superconducting cat qubits that exhibit natural protection against bit-flip errors, potentially reducing the number of physical qubits needed for logical qubits by orders of magnitude. Alice & Bob’s technology addresses one of quantum computing’s most critical challenges: achieving fault-tolerant quantum computing with manageable hardware overhead. The company has secured significant funding from European investors and established partnerships with research institutions and industry collaborators. Their cat qubit approach represents a fundamentally different path toward practical quantum computing, potentially enabling quantum advantage with far fewer physical qubits than conventional approaches. Alice & Bob’s innovative technology positions France and Europe as leaders in the race toward fault-tolerant quantum computing.
