  1. 1. Classical motion in synthetic monopole fields

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Ola Carlsson; [2022]
    Nyckelord :;

    Sammanfattning : In the Born-Oppenheimer approximation for a quantum system the emergent synthetic magnetic field can be seen as generated by monopoles at points of degeneracy, in full analogue to the synthetic fields generating the geometric phase of adiabatically evolving quantum systems. The plausibility of using these synthetic magnetic monopoles as a means to study magnetic monopole dynamics in the absence of fundamental magnetic monopoles has been explored. LÄS MER

  3. 2. X-ray-induced intermolecular reactions in mixed clusters

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Astrid Bergman; [2022]
    Nyckelord :molecular cluster; biophysics; X-ray;

    Sammanfattning : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. LÄS MER

  4. 3. Folding HP Proteins on a Quantum Annealer

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Lucas Knuthson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. LÄS MER

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

    Kandidat-uppsats, Uppsala universitet/Materialteori

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

    Sammanfattning : 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. LÄS MER

  7. 5. Adiabatisk genväg till quditberäkning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Kellen Smith; [2021]
    Nyckelord :adiabatic shortcut; qudit; quantum computation; logic gate; holonomy; geometric phase; robust gates;

    Sammanfattning : One of the major challenges hindering advancement of quantum computing is the sensitive nature of the physical systems used to build a quantum computer. One suggestion for improving reliability is a particular type of logic gates, based on Berry's geometric phase, showing improved robustness to external disturbance of the quantum system over the course of a calculation.
