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.
The internship will start in September 2026.
Responsibilities:
- 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.
At Alice & Bob you will:
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
