  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. 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.

  4. 3. Continuous-variable quantum annealing with superconducting circuits

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Pontus Vikstål; [2018]
    Nyckelord :quantum annealing; adiabatic quantum computing; continuous variables; coherent states; Wigner function; superconducting circuits; Kerr-nonlinear resonator.;

    Sammanfattning : Quantum annealing is expected to be a powerful generic algorithm for solving hard combinatorial optimization problems faster than classical computers. Finding the solution to a combinatorial optimization problem is equivalent to finding the ground state of an Ising Hamiltonian. LÄS MER

  5. 4. Fidelity of geometric and holonomic quantum gates for spin systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Teoretisk kemi

    Författare :Daniel Töyrä; [2014]
    Nyckelord :geometric quantum gates; holonomic quantum gates; operator fidelity;

    Sammanfattning : Geometric and holonomic quantum gates perform transformations that only dependon the geometry of a loop covered by the parameters controlling the gate. Thesegates require adiabatic time evolution, which is achieved in the limit when the looptakes infinite time to complete. LÄS MER
