  1. 1. 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

  3. 2. Improving Dependability of Space-Cloud Payload Processor by Storage System

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Hassan Said; Stephanie Liza Johansson; [2023]
    Keywords : Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

    Abstract : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. READ MORE

    Abstract : In telecommunication, messages sent through a wireless medium often experience noise interfering with the signal in a way that corrupts the messages. As the demand for high throughput in the mobile network is increasing, algorithms that can detectand correct these corrupted messages quickly and accurately are of interest to the industry.

    Abstract : This research study aims to investigate the capacity of single photons to carry information through polarization and time ordering and proposes a protocol called Beyond Pulse Position Modulation (BPPM) to improve photon-based communication reliability over longer distances with limited power. Such a protocol may be used in any communication scenario where energy efficiency is important, e. READ MORE

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

    University essay from KTH/Datavetenskap

    Author : Tobias Jogården; Mark Bergrahm; [2022]
    Keywords : ;

    Abstract : 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. READ MORE
