Job description

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 140+ brilliant minds from over 20 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 intern in our Simulation Model team, you will work on the development of efficient numerical simulation techniques for driven-dissipative bosonic systems, specifically focusing on cat qubits. The project aims to address the challenges associated with simulating many coupled cat qubits, where conventional methods struggle. You will leverage stochastic methods to capture relevant information of the system. This project is a great opportunity to contribute to cutting-edge quantum research at Alice&Bob while gaining hands-on experience in advanced numerical techniques.

The proposed internship period is six months between January 2026 and June 2026. 

Responsibilities:

  • Familiarize yourself with cat qubits, density matrix formalism and stochastic models
  • Develop efficient stochastic methods to simulate cat qubit evolution
  • Develop Python code to implement the numerical method for efficient simulations.
  • Apply the developed methods to study important physical problems involving cat qubits.

    • Requirements:

  • You are currently enrolled in a relevant degree at the Master's level and are looking for a 4 to 6-month internship.
  • You have completed coursework in quantum mechanics and numerical simulations.
  • You are experienced in Python programming and numerical modeling.
  • You ideally have experience in stochastic methods and quantum trajectories.
  • You are a curious, motivated, and proactive individual with a desire to contribute to cutting-edge research in a fast-paced environment.

    • We're also looking for:

  • Being familiar with superconducting qubits is a bonus.

    • Benefits:

    - 1 day off per month

    - Half of transportation cost coverage (as per French law)

    - Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen

    Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

    You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

    We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
