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. Model Predictive Climate Control for Electric Vehicles

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Erik Norstedt; Olof Bräne; [2021]
   Keywords : MPC; model predictive control; climate control; electric vehicle; battery; thermal management; electrified vehicle; battery electric vehicle; nonlinear MPC; custom cost functions; elfordon; temperaturreglering;

   Abstract : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

4. 3. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

5. 4. Continuous-variable quantum annealing with superconducting circuits

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Pontus Vikstål; [2018]
   Keywords : quantum annealing; adiabatic quantum computing; continuous variables; coherent states; Wigner function; superconducting circuits; Kerr-nonlinear resonator.;

   Abstract : Quantum annealing is expected to be a powerful generic algorithm for solving hard combinatorial optimization problems faster than classical computers. Finding the solution to a combinatorial optimization problem is equivalent to finding the ground state of an Ising Hamiltonian. READ MORE

6. 5. Analysis of Digital Predistortion in a Wideband Arbitrary Waveform Generator

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Marcus Eriksson; [2015]
   Keywords : Digital Predistortion; Nonlinear Systems; Linearization; Inverse System Estimation;

   Abstract : Digital predistortion is a signal processing technique used to remove undesired distortions caused by nonlinear system effects. This method is predominately used to linearize power amplifiers in communication systems in order to achieve efficient transmitter circuits. READ MORE
