1. 1. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Mohamed Abrash; [2023]
   Nyckelord :Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

   Sammanfattning : 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. 3. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Henrik Åkerberg; [2023]
   Nyckelord :Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

   Sammanfattning : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. LÄS MER

5. 4. Digital Microwave Control of Superconducting Qubits

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Giuseppe Ruggero Di Carlo; [2022]
   Nyckelord :Superconducting qubit; High-fidelity readout; Real-time reset; iSwap gate; FPGA; RFSoC; template matching.; Supraledande kvantbit; Avläsning med hög tillförlitlighet; realtidsåterställning; iSwap-grind; FPGA; RFSoC; mallmatchning.;

   Sammanfattning : 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

7. 5. Magnetically tunable microwave resonator/filter

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zhi Ye; [2022]
   Nyckelord :Magnetic tuning; Ferrite; Substrate integrated waveguide resonator; Substrate integrated waveguide filter; Magnetisk inställning; Ferrit; Substratintegrerad vågledarresonator; Substratintegrerad vågledarfilter;

   Sammanfattning : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. LÄS MER
