1. Simulating the Impact of Noise on Quantum Walk Algorithm
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Quantum computing has recently shown promise for improving the efficiency of some classical algorithms. However, quantum computing suffers from issues in reliability due to the fundamental problem of quantum mechanics called decoherence. LÄS MER
2. Hybrid Microwave Resonator-Nanoscale Conductor Systems
Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
3. Gravitational Decoherence in Macroscopic Quantum Systems
Kandidat-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : 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. LÄS MER
4. Continuous Quantum Control of Quantum Dot Systems
Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. LÄS MER
5. Gossiping electrons : Strong decoherence from screening
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : In a strongly correlated material the localized electrons, typically the electrons in the 3d-orbitals, become entangled with each other through the Coulomb interaction. However, these electrons also interact with more mobile (itinerant) electrons in the s- and p-orbitals. LÄS MER
