1. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?
Master-uppsats, Uppsala universitet/MaterialteoriSammanfattning : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. LÄS MER
2. 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
3. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS
Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. LÄS MER
4. 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
5. Implementing two-qubit gates along paths on the Schmidt sphere
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : Qubits (quantum bits) are what runs quantum computers, like a bit in classical computers. Quantum gates are used to operate on qubits in order to change their states. As such they are what ”programmes” a quantum computer. LÄS MER
