1. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires. 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. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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. LÄS MER
