  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. Comparing performance of Grover's algorithm with and without phase flip error correction

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Tobias Jogården; Mark Bergrahm; [2022]
    Nyckelord :;

    Sammanfattning : Quantum physics tells of our reality being probabilistic at the microscopic level. Expanding on that research, quantum computing was born, which leverages these microscopic entities with probabilistic properties to perform computation. These units of computation in quantum computing are so-called qubits. LÄS MER

  4. 3. The Role of Data in Projected Quantum Kernels: The Higgs Boson Discrimination

    Master-uppsats, KTH/Fysik

    Sammanfattning : The development of quantum machine learning is bridging the way to fault tolerant quantum computation by providing algorithms running on the current noisy intermediate scale quantum devices.However, it is difficult to find use-cases where quantum computers exceed their classical counterpart.

    Sammanfattning : A Kitaev quantum spin liquid is a phase of matter predicted to host excitations that can be used to preform fault-tolerant quantum computation. Though the theoretical prediction of such a state is on firm footing, its realisation in real materials has proven to be elusive. LÄS MER
