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!

The EDA Research team is developing simulation tools that predict physical and logical performance of our superconducting chips. These tools include FEM software for electromagnetic problems, reduced-order modeling schemes, efficient numerical solvers, and frameworks for approximations of effective quantum problems. Together they form a simulation pipeline that is essential for the chip design process at Alice & Bob, which relies heavily on simulations for design optimization and verification before fabrication and measurement.

FEM simulations of entire chips are possible but computationally expensive. To increase our iteration speed and enable simulation of large-scale designs, we decompose chips into smaller components that we simulate in isolation, to then solve for their resulting interaction. This method is, by current design, ignoring long-range interactions between components (the so-called cross-talks).

Your role will be to help us tackle this issue by developing an understanding of the nature and effects of cross-talk and improve our method to correctly account for it.

Responsibilities:

    At Alice & Bob you will:

  • Discover and learn about the design of superconducting qubit chips.
  • Understand the origin and nature of cross-talks in planar circuits.
  • Identify or develop suitable models to predict their effects.
  • Quantify their effects for typical chips, and how they will scale with the chip size.
  • Use these models to improve our simulation suite.
  • Communicate and explain your work.

Requirements:

  • Currently studying at Master-level in Electrical Engineering / Physics / Quantum Engineering / Applied Mathematics / Computer Science
  • Experience with FEM applied to electromagnetic problems, and electrical circuit analysis
  • Experience with software development in Python
  • Fluent in English, with strong written and verbal communication skills
  • Ability to work collaboratively
  • Strong analytical and critical thinking
  • Ability to explain complex phenomena clearly

Nice to have:

  • Willingness to deep-dive in theoretical and mathematical physics models
  • Familiarity with circuit quantum electrodynamics
  • Curiosity about quantum computation
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.
