LFQ IRL (English subtitles)

Louis TAILLEFER (Université de Sherbrooke), Director of Laboratoire Frontières Quantiques (LFQ), tells us about his International Research Laboratory (IRL).

LFQ is an IRL created in 2022 as part of a long-standing collaboration between the Université de Sherbrooke and the CNRS. This 18-member laboratory, co-directed by Louis Taillefer (Université de Sherbrooke) and Cyril Proust (CNRS), aims to conduct cutting-edge international collaborative research in quantum science and technology, consolidating French and Canadian leadership in quantum research.

LFQ focuses on three main areas of research:

• Quantum materials: high-temperature superconductivity, spin liquids, topological materials, Planckian dissipation, quantum criticality.
• Quantum circuits and devices: simulators and metamaterials, superconducting and mixed circuits, quantum signals, superconducting and spin qubits, quantum electronics, quantum architectures.
• Quantum technologies

The LFQ also helps support Franco-Canadian scientific cooperation. The laboratory enables the mobility of researchers and students between the Université de Sherbrooke and French universities. In 2022 and 2023, 20 French students did their M2 internship at the Institut Quantique (IQ) of the Université de Sherbrooke. Currently, the IQ hosts 7 doctoral theses under joint supervision (between the Université de Sherbrooke and a French university).

Over the past 15 years, exceptional discoveries have emerged from the complementary expertise of the French and Canadian scientific communities in quantum science and technology. The LFQ is the result of this historic cooperation and provides a mutually beneficial exchange of expertise and state-of-the-art facilities. This IRL is backed up by access to major research infrastructures in France, at the Institut Quantique de l’Université de Sherbrooke and its Quantum FabLab.
