Modelling Non-Markovian Quantum Systems Using Tensor Networks

This thesis presents a revolutionary technique for modelling the dynamics of a quantum system that is strongly coupled to its immediate environment. This is a challenging but timely problem. In particular it is relevant for modelling decoherence in devices such as quantum information processors, and how quantum information moves between spatially separated parts of a quantum system.

The key feature of this work is a novel way to represent the dynamics of general open quantum systems as te...
