  1. 1. Decoding the surface code using graph neural networks

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Moritz Lange; [2023-10-17]
    Nyckelord :;

    Sammanfattning : Quantum error correction is essential to achieve fault-tolerant quantum computation in the presence of noisy qubits. Among the most promising approaches to quantum error correction is the surface code, thanks to a scalable two-dimensional architecture, only nearest-neighbor interactions, and a high error threshold. Decoding the surface code, i.e. LÄS MER

  3. 2. The Impact of Quantum Computing on the Financial Sector : Exploring the Current Performance and Prospects of Quantum Computing for Financial Applications through Mean-Variance Optimization

    Master-uppsats, Linköpings universitet/Produktionsekonomi

    Författare :Ante Fahlkvist; Alfred Kheiltash; [2023]
    Nyckelord :Quantum computing; Finance; Financial applications; Mean-variance optimization; Zero-one quadratic programming; Quantum computing in finance;

    Sammanfattning : Many important tasks in finance often rely on complex and time-consuming computations. The rapid development of quantum technology has raised the question of whether quantum computing can be used to solve these tasks more efficiently than classical computing. LÄS MER

  4. 3. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

    Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emil Adam Jonatan Östberg; [2023]
    Nyckelord :skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Sammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER

  5. 4. Introducing Quantum Computation in Education

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Amadeus Hedenskog; [2023]
    Nyckelord :Quantum computation; Quantum computing; Education;

    Sammanfattning : Quantum Computation is the quest for more efficient technologies. It can in principal be applied to Complex quantum systems, Quantum chemical systems, Cyber-security, Finance and AI. However, the introductory course in Quantum Mechanics at the Luleå University of Technology (F0047T) does not provide an introduction to Quantum Computation. LÄS MER

  7. 5. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Johanna Adbo; [2023]
    Nyckelord :QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

    Sammanfattning : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. LÄS MER
