The group ‘Theory of Superconducting Quantum Devices’ at the Institut quantique of the Université de Sherbrooke focuses on the physics of superconducting quantum circuits, and more particularly circuit quantum electrodynamics, with applications to quantum information processing and quantum optics. Our theoretical work is done in close collaboration with experimental groups worldwide.

# Theory

The main scientific interest of the Theory of Quantum Systems group is related with the modeling of nano- and mesoscopic systems. The area of interest includes unconventional states of matter in highly correlated electron systems (high-temperature superconductors and magic-angle twisted bilayer graphene), solid hydrogen phases (molecular and its metallization), as well as metallic nanofims and oxide interfaces.

How do isolated quantum systems behave when prepared in a highly non-equilibrium state? How can such quantum systems avoid the ubiquitous relaxation to a thermal equilibrium? How can we gain novel insights into properties of quantum matter using modern nonequilibrium probes? These and other open questions in the field of quantum non-equilibrium matter are the focus of the Serbyn group.
