Alice & bob

Cross-talk Investigation & Simulation Internship H/F

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'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.
