1. 1. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

   University essay from KTH/Tillämpad fysik

   Author : Sara Persia; [2022]
   Keywords : Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

   Abstract : 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.

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
