October 7, 2025 — Alice & Bob, a global leader in fault-tolerant quantum computing, celebrates the recognition of Michel H. Devoret and John M. Martinis as recipients of the Nobel Prize in Physics 2025. The Royal Swedish Academy of Sciences awarded the Nobel Prize to John Clarke, Michel H. Devoret, and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.” This honors their work in superconducting qubit technology, central to the development of advanced quantum computers, including the cat qubit developed at Alice & Bob.
Michel Devoret, a key figure in superconducting qubits, co-invented the cat qubit, Alice & Bob’s flagship technology. Before joining Google, he advised Alice & Bob’s co-founders.
Benjamin Huard, co-founder of the Quantum Electronic Group at ENS and Alice & Bob scientific board member, notes that their work triggered superconducting qubit research and demonstrated that an electrical circuit obeys quantum physics.
John M. Martinis, an Alice & Bob consultative board member, has been advising the company on critical scientific matters alongside David DiVincenzo, Yasunobu Nakamura, and Daniel Gottesman.
Raphael Lescanne, CTO and Co-Founder of Alice & Bob, stated that the award recognizes a decades-long scientific journey at the intersection of theoretical and experimental quantum physics and that the seminal work of these pioneers is becoming a true computing innovation.
Alice & Bob, founded in 2020, aims to create the first universal, fault-tolerant quantum computer. It has raised €130 million in funding, hired over 150 employees, and demonstrated experimental results surpassing those of technology giants such as Google or IBM. Alice & Bob specializes in cat qubits, a technology later adopted by Amazon. Alice & Bob showed that it could reduce the hardware requirements for building a useful large-scale quantum computer by up to 200 times compared with competing approaches.
