Internship: Quantum Error Correction in the SPOQC architecture (H2-2026)

About the role

About Quandela Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company's unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors. Join Us at the Forefront of Quantum Computing Innovation 🚀 Description of the Team/Project You will join the Fault-Tolerant Quantum Computing team within Quandela's Architecture division. The team brings together researchers, engineers, and students working on Quantum Error Correction and fault-tolerant protocols. The team works closely with the quantum information, quantum device physics, software and experimental teams across the company. Within this framework, you will contribute to the development of quantum error correction and fault-tolerant computing strategies that enable the scaling of Quandela's Spin-Optical Quantum Computing architecture specifically working on exploring hyperbolic and semi-hyperbolic floquet codes in the SPOQC architecture. (Semi)-Hyperbolic Floquet codes are a class of dynamical quantum error-correcting codes whose implementation relies solely on pair measurements, and that offer good asymptotic scaling for both their physical- to logical-qubit encoding rate and distance. However, due to the underlying hyperbolic geometry, their realization requires long-range connexion. Furthermore, it is yet unclear how to perform logical operations on these codes beyond simple information protection. The internship offers two axes that can be explored in parallel: (a) the implementation of these codes on Quandela's SPOQC architecture, and especially the impact of long range connexions on the fault-tolerance offered by these codes, (b) transferring to these codes, if possible, known methods to perform logical operations based on lattice deformations (eg Dehn twists). The intern is expected to conduct a thourough litterature review, explore the topics of the internship and produce a detailed report as well as some well-documented code. You are currently enrolled in a university or in a higher education program in Physics, Mathematics, or Computer Science. The position is only valid with an internship agreement. You have experience with, or strong interest in quantum computing, quantum information theory or quantum error correction. You are curious and love solving problems. Coding skills are appreciated (esp. Python). Strong communication in English, French is a plus.
