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. Revival structure of the residual entanglement in a three-qubit system

   Kandidat-uppsats,

   Författare :Carl Agelii; Rasmus Andersson; William Bakke Lindblom; [2023]
   Nyckelord :qubit; tripartite entanglement; residual entanglement; antisymmetric exchange; Quantum Heisenberg model;

   Sammanfattning : The quantum mechanical phenomenon of entanglement plays a key role in areas such as quantum computing and quantum information. Entangled half spin particles, often called qubits, are used to realize quantum based logic which means that studying systems of qubits and their properties is of vital importance to the development of the fields.

4. 3. Residual Bell Nonlocality

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Parham Azish; [2020]
   Nyckelord :Bell inequality; Nonlocality; Three-qubit system; tripartite Nonlocality; Bells olikhet; ickelokalitet; tre-kvantbitsystem; Tredelad ickelokalitet;

   Sammanfattning : This report provides a new theoretical measure for the nonlocality of an arbitrary three-qubit pure state system similar to the method used to describe tripartite entanglement, resulting in a concept referred to as residual nonlocality, η. This report also investigates the special cases that can be encountered when using η. LÄS MER
