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

4. 3. Utilizing Neural Networks To Adaptively Demodulate And Decode Signals In An Impulsive Environment

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datalogi

   Författare :Andreas Andersson; [2023]
   Nyckelord :Neural Network; Demodulation; Decoding; Impulsive Noise; Alpha-stable Noise;

   Sammanfattning : Electromagnetic disturbance can be detrimental to the performance of a radio communication system, and in today’s society where more and more electronic devices are present in our everyday life it is increasingly vital to consider man-made interference. A communication system can take into consideration the noise characteristics and by doing so will excel in such areas, however, this follows that the algorithms utilized in such systems are more computationally complex and are therefore slow.
