Quantum Algorithms Scientist
Alice & Bob
Paris, France
Posted on Oct 2, 2025
Alice & Bob is a rapidly growing deeptech company going through the R&D stage to shape the future of Quantum computing. A diverse team of brilliant minds from over 20 countries, we're on a mission to revolutionize technology and benefit humanity by building the first universal, fault-tolerant quantum computer with a new kind of superconducting qubit: the Schrödinger cat qubit.
While we're dedicated to our work, we also value a fun and collaborative culture.
Are you ready to join us on this groundbreaking journey? Join us today!
About the role
As a Quantum Algorithms Scientist, your role is to develop the first fault-tolerant quantum computing (FTQC) applications for Alice & Bob's architecture, primarily in quantum simulation (e.g., condensed matter physics and quantum chemistry). You will also serve as a scientific expert in collaborations with academic and industry partners.
Responsibilities
- Pioneer new quantum computing methods.
- Optimize the implementation of quantum algorithms to our architecture, and challenge it.
- Work on the first unchallenged quantum advantage (as soon as Alice & Bob's hardware becomes available).
- Actively engage in scientific collaborations with academic institutions and private industry.
- Drive the commercialization of developed quantum algorithms by identifying high-value industry applications and collaborating with R&D partners to mature the technology.
Requirements
- A PhD or 3+ years research experience in quantum computing or condensed matter physics or related fields (quantum chemistry, nuclear physics, particle physics...).
- Successful track-record of driving research initiatives and solid publication portfolio.
- Professional-level English proficiency, both written and spoken.
Nice to Have
- Experience in the intersection between quantum computing and quantum chemistry, nuclear physics or high energy physics.
- Strong experience with software design and best practices.
- Practical knowledge of quantum computing hardware and error correction.
Benefits
- 25-day vacation policy (as per French law) + RTT
- Half of transportation cost coverage (as per French law), or yearly allowance for bike enthusiasts
- Competitive health benefits with Helium/AXA
- Meal vouchers with Swile, as well as access to a fully equipped kitchen
