  1. 1. Robust non-Abelian geometric phases on three-qubit spin codes

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Parham Azish; [2024]
    Nyckelord :Quantum information theory; Holonomic quantum computing; non-abelian systems;

    Sammanfattning : Quantum holonomies are non-Abelian Geometric Phases predominantly observed in adiabatic, non-adiabatic, or measurement-based quantum evolutions. Their significance lies in their potential utility within quantum computing due to their robustness against noise throughout the parameter path. LÄS MER

  3. 2. 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

  4. 3. 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
