Alice & Bob is a French quantum computing company developing cat qubits - a type of superconducting qubit that inherently suppresses bit-flip errors through bosonic encoding. This 'biased-noise' approach dramatically reduces the overhead needed for quantum error correction, potentially requiring 10-100x fewer physical qubits per logical qubit compared to surface codes.
