Les Houches Summer School Lecture Notes

One of the most successful modern approaches to interacting quantum systems is through the concept of quantum information. The school covered mainly topics in quantum information applied to condensed matter many-body physics (tensor networks, random circuits, topological excitations, quantum simulators, transport, effect of chaos and decoherence), as well as their relations to high energy physics/holography. The theoretical perspective is centered on integrability and exact solvability in a broader sense.
