Grégoire Misguich

Researcher in physics - Condensed matter theory and statistical Phsyics


I am doping research in statistical physics and correlated electron systems, and particulary quantum Hall systems, low dimensionnal quantum magnets, topological phases, quantum entanglement and the out-of-equilibrium dynamics of these systems. I am also working on the simulation of noisy quantum devices using matrix product states and matrix product operators (MPO).

An open-source MPO-based simulator for interacting qubits with some decoherence (open system and Lindblad evolution): github.com/qiskit-community/lindbladmpo

I am participating in the research projects EPiQ and BACQ.
