Quantum materials

What is it?

Quantum materials are substances whose physical properties are dominated by quantum effects, often imperceptible in traditional materials. These materials exhibit exotic behaviors, such as superconductivity, where electricity flows without resistance, or topological phases, which are protected against certain disturbances. Quantum materials also include Mott insulators, topological insulators and Weyl semi-metals, which defy the classical laws of physics. Their study opens the way to new technological applications, such as ultra-sensitive detection devices, quantum computers and innovations in electronics.

History

The Institut quantique's research in quantum materials is part of a long tradition of cutting-edge research in condensed matter physics. For decades, Sherbrooke has been recognized for major advances in the study of materials with exotic properties, such as high-temperature superconductors, topological insulators and other correlated quantum systems.

Currently at IQ

The quantum materials research axis is supported by a diversity of complementary expertise in both theoretical and experimental physics. On the one hand, experimental researchers focus on the synthesis, characterization and study of new quantum materials, such as superconductors, topological materials and quantum insulators. Using advanced measurement techniques, particularly under extreme conditions of temperature, pressure and magnetic field, they are exploring the exotic behaviors that emerge in these systems.

On the other hand, theorists are developing models and simulations to better understand the quantum phenomena observed in these materials, such as quantum entanglement, quantum phase transitions and the dynamics of strongly correlated electrons. Their work not only predicts new phases of matter, but also guides experiments towards even more far-reaching discoveries.

Together, this combination of theoretical and experimental expertise is pushing back the frontiers of understanding quantum materials, paving the way for innovations in fields such as quantum sensors, next-generation electronic devices, and potentially materials for quantum computing.
