Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We're a diverse team of 180+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
As part of the Quantum Hardware department, the “nanofabrication backend” team plays a pivotal role in operating and developing the “backend of line” used for manufacturing Alice&Bob Quantum Processor. Technically, this encompasses:
The team is in charge of:
About the role :
As nanofabrication backend technician, you will play a key role in bringing into reality the QPU designs imagined by the company. Your technicity and attention to the details will directly contribute to our technical excellence and speed of execution, shaping the future of quantum computing. For this position, we are seeking a technician with a background in backend / electrical tests in semiconductor/superconductor processes to join our talented team.
Alice&Bob développe un ordinateur quantique basé sur des qubits chats. Après avoir initialement réalisé la nanofabrication des circuits dans des salles blanches académiques, Alice&Bob passe à la vitesse supérieure en opérant sa propre salle blanche de prototypage en Île-de-France.
Au sein du département Quantum Hardware, l’équipe « nanofabrication backend » jouer un rôle central dans le process de fabrication des processeurs quantiques d’Alice&Bob. Elle est notamment en charge de :
