Quantum Resource Estimation Intern — Cat-Qubit Tech

Alice & Bob; Paris; On-site; EUR 10,000 - 15,000; Full time

Benefits offered by this job

1 day off per month

Transportation cost coverage

Meal vouchers (Swile)

Job summary

Alice & Bob is developing the first universal, fault-tolerant quantum computer. The Quantum Algorithms Intern will review compact block-encoding techniques and estimate physical resources for a cat-qubit architecture at a small scale. You will work under the Quantum Algorithm Scientist and deliver a concrete physical resource estimate for a chosen use case.

The internship starts January 2027 for 6 months. Applicants should be MSc/PhD students in physics or mathematics, with strong quantitative

Qualifications

• Education: Currently enrolled in an MSc or PhD program in physics or mathematics.
• Proficient in English.
• No minimum professional experience required; prior research project or internship in quantum computing is an asset.
• Solid understanding of quantum computing fundamentals (circuit model, quantum gates, basic quantum information).
• Strong linear algebra and mathematical reasoning.
• Basic programming skills (Python preferred).
• Ability to read and synthesize research literature.
• Clear written and oral communication of technical results.
• Autonomy and rigour in research work.

Responsibilities

• Review block-encoding techniques with a small footprint (such as a blockencoding for the SYK model) and compare their logical resources.
• Estimate the physical resources on a cat-qubit architecture—Map the logical resources of one selected example onto Alice & Bob's cat-qubit architecture—Compute the physical cat-qubit count and runtime in reproducible code, and document the results.
