Physical Resource Estimation Intern (Quantum Computing)

Location: Paris, France; hybrid workplace. The internship starts in January 2027 and lasts 6 months.

Company

Alice & Bob is developing a universal, fault-tolerant quantum computer based on superconducting Schrödinger cat qubits, with a team of more than 250 people from over 35 countries.

What you will do

• Review compact block-encoding techniques, including block encodings for models such as SYK, and compare their logical resources.
• Estimate physical resources for a selected example on a superconducting cat-qubit architecture.
• Map logical resources onto the cat-qubit architecture.
• Compute the physical cat-qubit count and runtime using reproducible code.
• Document the resource-estimation results and communicate the technical findings.

Requirements

• Currently enrolled in an MSc or PhD program in physics or mathematics.
• Proficient in English.
• No minimum professional experience is required.
• Strong interest in quantum computing and quantum algorithms, with a solid understanding of quantum computing fundamentals, including the circuit model, quantum gates, and basic quantum information.
• Strong linear algebra and mathematical reasoning skills.
• Basic programming skills, preferably in Python.
• Ability to read and synthesize research literature.
• Clear written and oral communication of technical results.
• Ability to work independently with autonomy and rigour on a well-defined research project.

Nice to have

• Prior research project or internship experience in quantum computing.
• Knowledge of quantum algorithms such as block encodings, qubitization, or phase estimation.
• Familiarity with fault-tolerant quantum computing or quantum error correction.

Culture & Benefits
