1. 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
2. Digital Microwave Control of Superconducting Qubits
Master-uppsats, KTH/Tillämpad fysikSammanfattning : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. LÄS MER
3. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER
4. Optimizing numerical modelling of quantum computing hardware
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Quantum computers are being developed to solve certain problems faster than classical computers. Instead of using classical bits, they use quantum bits (qubits) that utilize quantum effects. LÄS MER
5. Characterization of InAs-Al semiconductor-superconductor hybrid devices
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. LÄS MER
