Alice & Bob raises €100M Series B for cat-qubit quantum computers

Alice & Bob/Cat-qubit roadmap

Paris-based Alice & Bob raised €100 million in Series B led by Future French Champions, AXA Venture Partners and Bpifrance. The company builds superconducting 'cat qubits' designed to resist bit-flip errors, aiming for a useful quantum computer by 2030.

• Cat qubits suppress bit-flip errors, reducing hardware requirements by ~200x vs. competing approaches.
• Company plans: cat-qubit approach would need thousands rather than millions of qubits.
• Funding for enhanced performance, first error-corrected logical qubit, production facility and team expansion.
