1. 1. Digital Microwave Control of Superconducting Qubits

   University essay from KTH/Tillämpad fysik

   Author : Giuseppe Ruggero Di Carlo; [2022]
   Keywords : 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.;

   Abstract : 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. 2. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

   University essay from KTH/Tillämpad fysik

   Author : Daniele Lopriore; [2022]
   Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

   Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE
