  1. 6. Time-optimal holonomic quantum computation

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Gabriel O. Alves; [2022]
    Nyckelord :Holonomic quantum computation; Open quantum systems; Non-adiabatic quantum gate; Geometrical phase;

    Sammanfattning : A three-level system can be used in a Λ-type configuration in order to construct auniversal set of non-adiabatic quantum gates through the use of non-Abelian non-adiabatic geometrical phases. Such construction allows for high-speed operation times which diminish the effects of decoherence. LÄS MER

  3. 7. Holonomic Optimal Control for Qudits

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Tomas André; [2022]
    Nyckelord :;

    Sammanfattning : Non-adiabatic Holonomic Quantum Computation (NHQC) is a method used to implement quantum gates with holonomies that arise solely from non-Abelian geometric phases. Due to high noise tolerance these phases can be used to construct resiliant quantum gates. LÄS MER

  4. 8. Matter-streams as sources of the Kerr metric

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Julian Boy; [2022]
    Nyckelord :General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Sammanfattning : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. LÄS MER

  5. 9. Material Characterization and Blade Impact Simulation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER

  7. 10. Studies on Reverse Engineering of Constant Frequence Geometric Quantum Gates

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Wu Zijin; [2022]
    Nyckelord :;

    Sammanfattning : Geometric Quantum Computation (GQC) is one of the effective methods to realizequantum computation. By using geometric phases, it shows robustness to certainerrors. This thesis aims to develop a new systematic technique for implementing GQC,especially in non-adiabatic systems. LÄS MER
