Overview
Alice & Bob develops superconducting quantum computers based on cat qubits. The design is intended to suppress bit-flip errors and reduce the hardware overhead needed for fault-tolerant computation. On January 28, 2025, the company announced a €100 million Series B led by Future French Champions, AVP and Bpifrance. Elaia, Breega and Supernova Invest returned, with the European Innovation Council joining the round.
The funding supports systems development, error correction, staffing and a laboratory and production facility. A hardware strategy that reduces one type of error still has to demonstrate reliable logical operations at scale. The company's 2030 ambition is a development target, not an established date for broad commercial quantum advantage.
Why Alice & Bob is interesting
Its €100 million Series B funds a distinct hardware strategy: suppressing a class of errors in the qubit itself rather than relying only on adding more physical qubits.
