Quaternary Neural Belief Propagation Decoding of Quantum LDPC Codes with Overcomplete Check Matrices
Quantum low-density parity-check (QLDPC) codes are promising candidates for
error correction in quantum computers. One of the major challenges in
implementing QLDPC codes in quantum computers is the lack of a universal
decoder. In this work, we first propose to decode QLDPC codes with a belief
propagation (BP) decoder operating on overcomplete check matrices. Then, we
extend the neural BP (NBP) decoder, which was originally studied for suboptimal
binary BP decoding of QLPDC codes, to quaternary BP decoders. Numerical
simulation results demonstrate that both approaches as well as their
combination yield a low-latency, high-performance decoder for several short to
moderate length QLDPC codes.Comment: arXiv admin note: text overlap with arXiv:2212.1024
Fast calibration of heliostats

Towards deep learning based airborne monitoring methods for heliostats in solar tower power plants
While deep learning methods have proven their superiority over conventional image processing techniques in many domains, their use in airborne heliostat monitoring remains limited. Our aim is to bridge this gap by developing models to improve and extend existing image-based measurement methods in this field. We use Blender and BlenderProc to generate synthetic image data, which grants us access to vast amounts of training data essential for developing effective deep learning models. The exemplary model we train can potentially solve the following tasks related to airborne heliostat field monitoring: detection of heliostats and detection of mirror facet corners. Our promising preliminary results demonstrate the applicability of our approach to use synthetic training data for the development of the intended deep learning models
