1. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : 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. READ MORE

2. Digital Microwave Control of Superconducting Qubits
University essay from KTH/Tillämpad fysikAbstract : 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. READ MORE

3. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
University essay from KTH/Tillämpad fysikAbstract : 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. READ MORE

4. Optimizing numerical modelling of quantum computing hardware
University essay from Umeå universitet/Institutionen för fysikAbstract : 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. READ MORE

5. Characterization of InAs-Al semiconductor-superconductor hybrid devices
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : 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. READ MORE
