RF Sub Systems Design & Characterization… at Alice Bob · Paris

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 200+ 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 an RF Sub Systems Design & Characterization Intern, your mission is to support the design, development, integration, and validation of RF hardware used to control Quantum bits (Qubits). Guided by senior engineers, you will gain hands-on experience on leveraging performance RF instruments, characterizing cryogenic components, and automating test workflows. Following the candidate’s abilities, there will be 3 main possible topics to focus on: Cryogenic Bias tee footprint reduction RF Readout chain optimization at room temperature RF Readout chain optimization at cryogenic temperatures As part of the team, you will contribute to solving technical challenges involving the entire signal chain from room temperature to cryogenics, by designing RF sub systems prototypes on PCB, manipulating different instruments to acquire data, and gathering inputs from your market tech watch. Working closely with cross functional teams of engineers and scientists, you’ll help to improve system performance and develop the next generation of quantum hardware platforms. This internship will start in September 2026 for a duration of 5-6 months. Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
