Moreover, entanglement is an intrinsic property of quantum systems that can be used to protect and process quantum information. My thesis focuses on the utility of measurements in such a framework, notably by studying measurement-based quantum computation. A first goal is to improve a process in which a three-dimensional quantum state—known as a cluster state—is locally measured to perform computations on information encoded on a topological lattice while preserving it. Secondly, this thesis aims at understanding the fundamental reasons why quantum measurements can create long-range entanglement from a short-range entangled state, from a mathematical perspective. Indeed, long-range entangled states are of great interest from the perspective of quantum computing and quantum information protection, but are hard to create. Thanks to local measurements, however, this is much easier. Event Location: HENN 318
