Alice & Bob raised €100 million in a Series B funding round led by Future French Champions (FFC), AVP (AXA Venture Partners), and Bpifrance. Existing investors, including Elaia Partners, Breega, Supernova Invest, and Bpifrance, also participated. The company, founded in 2020, specializes in cat qubits, a technology that reduces the number of qubits needed for fault-tolerant quantum computing. The new funding will accelerate the development of an error-corrected logical qubit and expand the company’s team and infrastructure, including a new lab and production facility.
Alice & Bob aims to deliver a practical quantum computer by 2030. Unlike conventional quantum computing methods that require millions of qubits, the company’s cat qubit approach could reduce hardware needs to just thousands by suppressing bit-flip errors. Nearly half of the funding will support facility construction, while the remainder will enhance system performance and error correction.
• Series B funding: €100 million
• Lead investors: Future French Champions, AVP, Bpifrance
• Other participants: Elaia Partners, Breega, Supernova Invest, EIC
• Technology: Cat qubits with built-in bit-flip error suppression
• Objective: Build a fault-tolerant quantum computer by 2030
• Planned investments: New lab, production facility, team expansion
“Having established performance records with our cat qubits, Alice & Bob now enters a new phase focused on building a quantum computer that can deliver valuable results,” said Théau Peronnin, CEO of Alice & Bob. “Cat qubits are unique, as they make scaling quantum computers practical: where conventional approaches would require millions of qubits, we would need only thousands.”
