1. The Pseudo-Unitary Group U(p,q) in Quantum Magnonics
University essay from Uppsala universitet/MaterialteoriAbstract : The study of magnons is an essential part of combining quantum information science and spintronics, allowing for the investigation of quantum properties such as entanglement in solid-state devices. Magnons are commonly described using the theory of T. Holstein and H. READ MORE

2. Probabilistic Exact Inversion of 2-qubit Bipartite Unitary Operations using Local Operations and Classical Communication
University essay from KTH/FysikAbstract : A distributed quantum computer holds the potential to emulate a larger quantumcomputer by being partitioned it into smaller modules where local operations (LO)can be applied, and classical communication (CC) can be utilized between thesemodules. Finding algorithms under LOCC restrictions is crucial for leveraging thecapabilities of distributed quantum computing, This thesis explores probabilisticexact LOCC supermaps, that maps 2-qubit bipartite unitary operations to its inver-sion and complex conjugation.

3. Regional identity in a European context: A quantitative study exploring how regional attachment influences EU support in France
University essay from Lunds universitet/Statsvetenskapliga institutionenAbstract : This thesis explores the relationship between regional identity and its influence on EU support. Going beyond the common focus on decentralized countries or entire European contexts, the research specifically examines the influence of regional identity within the more unitary state of France.

4. The black hole information paradox and holography
University essay from Uppsala universitet/Teoretisk fysikAbstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

5. On quantum systems and the measurement problem
University essay from Stockholms universitet/FysikumAbstract : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. READ MORE
