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 250+ brilliant minds from over 35 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!

In a context where Alice & Bob is building a fault-tolerant quantum computer based on cat qubits, the Quantum Compilation Intern helps quantum programs run efficiently on this architecture. Reporting to the Senior Quantum Compilation Scientist, you will work closely with the Compilation team to develop, implement and integrate modern compilation algorithms that exploit the properties of cat qubits, in particular their noise bias toward phase-flip errors.

1- Review the cat-qubit architecture and the state of the art in compilation

Study cat-qubit physics, including the noise bias toward phase-flip errors, and the resulting gate set, connectivity and error-correction constraints

Study modern compiler design, from front end to code generation, and the structure of the company's existing compiler

Survey circuit synthesis, routing and optimization techniques and assess their relevance to cat-qubit architectures

2- Build intermediate representations and integrate compilation passes

Design and implement compiler intermediate representations (IRs)

Implement compilation passes and integrate them into the company's compiler

Test and document the implemented passes

3- Benchmark resource costs

Measure the resource costs of compiled programs, such as qubit count, gate count and runtime

Compare the results with existing compilation approaches and report the findings

You are a student with a strong foundation in both quantum computing and computer science, and an interest in the interface between quantum hardware and software. You can translate methods from the scientific literature into working, tested code. You work autonomously while seeking regular feedback from the team.
