1. Quantum Espionage
University essay from KTH/Tillämpad fysikAbstract : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. READ MORE

2. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. READ MORE

3. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains
University essay from Uppsala universitet/MaterialteoriAbstract : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. READ MORE

4. Hybrid Microwave Resonator-Nanoscale Conductor Systems
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. READ MORE

5. Gravitational Decoherence in Macroscopic Quantum Systems
University essay from Uppsala universitet/Teoretisk fysikAbstract : The problem of how quantum mechanics gives rise to classicality has been debated for more than a century. A commonly proposed solution is decoherence, i.e. the gradual decay of superpositions in open quantum systems due to their inevitable interaction with their environment. READ MORE
