  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. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

  3. 3. 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

  4. 4. Optimizing numerical modelling of quantum computing hardware

    University essay from Umeå universitet/Institutionen för fysik

    Author : Yasir Al-Latifi; [2021]
    Keywords : Quantum computers; transmon qubits; rotating-wave approximation; energy levels;

    Abstract : Quantum computers are being developed to solve certain problems faster than classical computers. Instead of using classical bits, they use quantum bits (qubits) that utilize quantum effects. READ MORE

  5. 5. Investigations of p-type quantum dots in GaSb nanowires

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

    Author : In-Pyo Yeo; [2021]
    Keywords : Physics and Astronomy;

    Abstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE
