Alice & bob

Numerical Methods Engineer (Superconducting Circuits) Internship (January 2026)

Paris Full Time
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 are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing  €100 million of funding in 2025 to develop our unique technology.
Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!

About the role:
The EDA Research team is developing the tools that predict the performance of our QPU designs. These tools are essential in the chip design process at Alice & Bob. Our predictions are currently computed using a pipeline of simulation tools, including FEM software for electromagnetic problems, frameworks for approximations of quantum problems, and efficient numerical solvers.

As an intern on this team, your mission will be to will be to develop and validate a simulation method to compute energy participation ratios of our superconducting chips to better predict qubit lifetimes.
