Graphene Quantum Advantage 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! Alice & Bob’s application team is pursuing the development of a quantum computer utilising cat qubits, with the goal of achieving a 100-logical-qubit system by the end of the decade. We are looking for a Master student to join us for 6 months to develop quantum algorithms for our first generation of fault-tolerant hardware.

Joining Alice & Bob will allow you to develop practical skills in quantum applications and contribute to the deployment quantum hardware. Research topic: applications for first generation fault-tolerant hardware As an intern, you will design a quantum algorithm for the simulation of quantum many-body systems with minimal hardware requirements, using techniques from dissipative state preparation. This internship will start in July 2026.

At Alice & Bob you will: Apply fault-tolerant techniques to improve state preparation of quantum systems on a quantum computer.

Implement corresponding code in Qualtran. Determine and optimise the required resources needed to run it.

Enrolled in a Master’s program in quantum physics, quantum information, computational physics, or a related field. Strong understanding of open quantum systems: density matrices, quantum channels, Lindblad dynamics, and dissipative processes. Experience with computational methods for simulating quantum systems. Proficiency in Python scientific computing (NumPy, SciPy, QuTiP, Qiskit, PennyLane, or similar tools). Professional-level English proficiency, both written and spoken.

Familiarity with cat qubits, or fault-tolerant quantum computing is a plus. Experience with Monte Carlo sampling, finite-shot statistics, or stochastic optimisation methods is a plus. Expertise in condensed matter physics / fault-tolerant algorithms/ open quantum systems / quantum information is a plus.

• 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.
