The funding will accelerate Alice & Bob’s path to build the world’s first useful quantum computer by 2030.
“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,” says CEO Théau Peronnin, “Cat qubits are unique, as they make scaling quantum computers practical: where conventional approaches would require millions of qubits, we would need only thousands.”
At the center of cat qubits’ hardware-efficiency is the inherent suppression of bit-flip errors, one of the two types of errors that plague quantum computers.
This property is key to enabling more efficient architectures for Fault-Tolerant Quantum Computers (FTQCs) that resist errors and can be used in real-world applications.
Alice & Bob claims to bethe only player developing quantum computers exclusively with this type of qubit, which the company has pioneered since its inception in 2020.
All Series A investors, Elaia Partners, Breega, Supernova Invest and Bpifrance, returned for the Series B round.
Alice & Bob will use the funding to enhance the performance of its system, improve error correction, and create its first error-corrected logical qubit.
Nearly half of the funds will be used to finance the ongoing construction of a state-of-the-art lab and production facility, and additional funds will be used to further expand the team, which has doubled in the past year.
