Quantum Cryptanalysis Research Internship (Al1c3_&_B0b) 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 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!

Join Alice & Bob for a research internship at the intersection of quantum computing and cryptography, where you will explore how emerging quantum algorithms challenge the security of widely used systems. This project focuses on implementing algorithms and estimating the concrete resources required to attack symmetric cryptographic schemes, with a particular emphasis on password-based security.

This role is ideal for candidates interested in applying quantum computing to real-world security questions and gaining hands-on experience alongside experts in quantum technologies and cryptography.

The internship will focus on resource estimation for quantum cryptanalysis. The work will specifically address symmetric cryptographic schemes, with an emphasis on password-based security, in the context of quantum algorithms such as Grover’s algorithm and novel ideas.

Responsibilities::
At Alice & Bob you will:

• Get an onboarding on the required technologies

• Study state of the art papers on the internship topic

• Implement selected algorithms

• Perform resource estimation of these algorithms and compare them

• Propose novel ideas and research directions, and implement them accordingly

• Document your implementations through reports and presentations

Requirements::
Last year of engineering school or Master degree, in cryptanalysis and/or quantum computing

Hard skills:

• Proficiency in Python (scientific computing, simulations, or algorithm implementation)

• Ability to read, understand, and implement research papers

• Knowledge of quantum computing concepts and/or cryptanalysis is a plus

Soft skills:

• Strong analytical thinking and problem-solving abilities

• Curiosity and interest in research-driven environments

• Ability to work autonomously on open-ended topics

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

• Team player mindset and collaborative attitude

• Written and oral skills in French is a 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

Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
