Quantum Error Correction Scheduling Internship H/F

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 200+ brilliant minds from over 30 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 Firmware department is conceiving and developing the fault-tolerant quantum software stack and the architecture of Alice & Bob quantum computer. Within the department, the QEC team is focused on developing new quantum error correcting codes and new protocols for fault-tolerant quantum compilation, as well as their practical implementations on superconducting cat qubits.

The goal is to replace some of the current technologies in the roadmap by easier, more practical alternatives.

The QEC Scheduling Intern will focus on exploring new directions to perform phase-flip error correction through simulation and analysis of quantum error correcting codes. You will study fault-tolerant quantum protocols based on multi-qubit Pauli measurements and investigate how different architectural choices affect key resources such as connectivity, qubit count, and circuit depth. The goal is to better understand the trade-offs involved and help assess whether these new approaches can enable more efficient quantum systems. This is a great chance to explore fault-tolerant quantum computing and see how different designs balance important factors like how qubits connect, how many are needed, and how deep the circuits go!

Responsibilities: :
At Alice & Bob you will:

• Explore scheduling strategies for fault-tolerant quantum circuits, with a focus on multi-qubit Pauli measurement schemes

• Benchmark trade-offs between qubit connectivity, total qubit count, and circuit depth across different architectures

• Develop and run numerical simulations to model quantum systems and protocol behavior under different architectural assumptions

• Analyze the implications of switching to new technologies, including effects on scalability, robustness, and efficiency

• Collaborate with researchers and engineers to translate theoretical concepts into practical simulation frameworks

• Document findings and present insights to the team, helping guide architectural and research decisions

Requirements::
• Currently pursuing a Master’s degree in engineering, physics, computer science, or applied mathematics

• Solid understanding of quantum mechanics and ideally quantum computing fundamentals

• Experience with numerical methods and scientific computing (e.g., simulation, optimization, linear algebra)

• Strong problem-solving skills and ability to work independently on open-ended research questions

• Fluent in English, with strong written and verbal communication skills

Nice to have::
• Prior experience in quantum information; experience in quantum error correction is a plus

• Familiarity with quantum circuit models, fault tolerance concepts, or error correction is a strong plus

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
