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. 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
3. Towards the detection of single photons in the mid-infrared
Master-uppsats, KTH/Tillämpad fysikSammanfattning : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms. LÄS MER
