  1. 1. Robust non-Abelian geometric phases on three-qubit spin codes

    University essay from Uppsala universitet/Materialteori

    Author : Parham Azish; [2024]
    Keywords : Quantum information theory; Holonomic quantum computing; non-abelian systems;

    Abstract : 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. READ MORE

  3. 2. Probabilistic Exact Inversion of 2-qubit Bipartite Unitary Operations using Local Operations and Classical Communication

    University essay from KTH/Fysik

    Author : Ludvig Lindström; [2024]
    Keywords : Resource Theory; Resource theory of entanglement; Quantum Information Theory; Quantum Computing; Distributed Quantum Computing; Higher-order quantum transformation; Quantum Algorithms; Quantum Physics; Resursteori; Resursteori för Kvantsammanflätning; Kvantinformationsteori; Kvantdatorer; Distribuerade kvantdatorer; Högre ordningens kvanttransformationer; Kvantalgoritmer; Kvantfysik;

    Abstract : A distributed quantum computer holds the potential to emulate a larger quantumcomputer by being partitioned it into smaller modules where local operations (LO)can be applied, and classical communication (CC) can be utilized between thesemodules. Finding algorithms under LOCC restrictions is crucial for leveraging thecapabilities of distributed quantum computing, This thesis explores probabilisticexact LOCC supermaps, that maps 2-qubit bipartite unitary operations to its inver-sion and complex conjugation.

  4. 3. A Comparative Investigation of Classical Random and Quantum Walks in Terms of Algorithms, Implementation, and Characteristics

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Naoki Moriya; [2024]
    Keywords : Qunatum computing; quantum walk;

    Abstract : In recent years, there has been a significant development in high performance computing, driven by advances in hardware and software technology. The performance of the computers to the present has improved in accordance with Moore’s law, on the other hand, it seems to be reaching the limits in the near future. READ MORE

  5. 4. Decoding the surface code using graph neural networks

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Moritz Lange; [2023-10-17]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Optimizing Quantum Computer Simulations With Data Compression & GPU Acceleration

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Erik Ljung; Darko Petrov; Felix Bråberg; Björn Forssén; Beata Ringmar; Jonas Hedlund; [2023-03-03]
    Keywords : ;

    Abstract : Simulating quantum computers involves high memory usage and often long execution times. For that reason the purpose of this project was to analyze whether data compression and GPU acceleration can be used to run simulations with more qubits than previously allowed. READ MORE
