  1. 1. 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.

  3. 2. Parallelizable manifold compactifications of D=11 Supergravity

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Roberto Goranci; [2016]
    Nyckelord :Supergravity; Compactification; Freund-Rubin; Parallelizable manifold; Fermion condensate; Holonomy; Scalar coset; squashed seven-sphere; Consistent truncations; Domain Walls; Membrane;

    Sammanfattning : In this thesis we present solutions of spontaneous compactifications of D=11, N=1 supergravity on parallelizable manifolds S^1, S^3 and S^7. In Freund-Rubin compactifications one usually obtains AdS vacua in 4D, these solutions usually sets the fermionic VEV's to zero. LÄS MER

  4. 3. Sequential Holonomic Quantum Gates : Open Path Holonomy in Λ-configuration

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Emmi Herterich; [2016]
    Nyckelord :Quantum Gate; Holonomy; Geometric Phase;

    Sammanfattning : In the Λ-system, non-adiabatic holonomic quantum phases are used to construct holonomic quantum gates. An interesting approach would be to implement open path holonomies in the Λ-system. By dividing the loop into two curve segments with a unitary transformation between them, universality can be reached. LÄS MER
