  1. 1. Quantum Portfolio Optimization : a Multi-Level Perspective Study of the Swedish Fund Management Industry

    University essay from KTH/Industriell ekonomi och organisation (Inst.); KTH/Industriell ekonomi och organisation (Inst.)

    Author : Olle Malmberg; Joakim Wellenstam; [2021]
    Keywords : Quantum computers; portfolio optimization; multi-level perspective; technological transition; finance; socio-technical; Kvantdatorer; portföljoptimering; multi-level perspective; teknisk omvandling; finans; socio-teknisk;

    Abstract : In recent years, quantum computers have achieved new levels of sophistication and are by some estimates only a few years from being used in production. A growing body of literature points toward their potential uses within various industries, with the finance industry identified as exceptionally full of prospective applications. READ MORE

  2. 2. Quantum thermodynamics explorations with a Hubbard-Holstein dimer

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Emil Adam Jonatan Östberg; [2021]
    Keywords : QTD Quantum Thermodynamics Hubbard-Holstein Hubbard Holstein dimer Lanczos Suzuki-Trotter ST Exact diagonalization ED Hysteresis Path dependence Battery Mott-insulator; Physics and Astronomy;

    Abstract : The goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. READ MORE

  3. 3. A Quantum Neural Network for Noisy Intermediate Scale Quantum Devices

    University essay from KTH/Tillämpad fysik

    Author : Altay Dikme; [2021]
    Keywords : ;

    Abstract : Neural networks have helped the field of machine learning grow tremendously in the past decade, and can be used to solve a variety of real world problems such as classification problems. On another front, the field of quantum computing has advanced, with quantum devices publicly available via the cloud. READ MORE

  4. 4. Adiabatic Shortcut to Geometric Quantum Computation in Noiseless Subsystems

    University essay from Uppsala universitet/Materialteori

    Author : Anton Gregefalk; [2021]
    Keywords : Quantum computer; Spin echo; Adiabatic shortcut; Berry s phase; Noiseless subsystems; Kvantdator; spinn eko; adiabatisk genväg; Berrys fas; Brusfria delsystem;

    Abstract : Quantum computers can theoretically perform certain tasks which classical computers at realistic times could not. Operating a quantum computer requires precise control over the system, for instance achieved by adiabatic evolution, and isolation from the environment to retain coherence. READ MORE

  5. 5. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Calle Stenberg; [2021]
    Keywords : double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

    Abstract : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.
