Decoding the surface code using graph neural networks
Lange, Moritz (2023-10-17)Quantum error correction is essential to achieve fault-tolerant quantum computation in the presence of noisy qubits. Among the most promising approaches to quantum error correction is the surface code, thanks to a scalable ... -
Development of a DEM-FEM framework for infrastructure simulations
Ullrich, Anita (2022-09-20)This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with ... -
Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging
Wittler, Henry (2023-11-29)Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we ... -
Lärares formande av en yrkesidentitet relaterad till hållbar utveckling
Bursjöö, Ingela (2011)Swedish schools are required to educate for sustainable development (ESD). The challenges for the teachers are demanding as the content is controversial and complex. This study focuses on exploring the different ways ... -
Opto-vibrational coupling in molecular solar thermal storage materials: Electronic structure calculations and neural-networkbased analysis Giannis Kostaras Degree project
Kostaras, Giannis (2021-01-26)Molecular solar thermal storage materials are proposed as a clean, renewable energy solution for a world with ever increasing energy needs. Norbornadiene is an organic compound suitable for molecular solar thermal storage ... -
Quantum Error Correction Using Graph Neural Networks
Bergentall, Valdemar (2021-06-17)A graph neural network (GNN) is constructed and trained with a purpose of using it as a quantum error correction decoder for depolarized noise on the surface code. Since associating syndromes on the surface code with ... -
Topological Band Theory, An Overview
Roderus, Jens (2021-06-14)Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explained by standard ...
