Modelling noise processes in noisy intermediate-scale quantum (NISQ) devices plays an important role in designing hardware and algorithms in the journey for scalable quantum computers. In this era, classical emulators of quantum systems can help to better understand typical errors in quantum information processing which arise from coupling to the environment and experimental limitations. We present a noise analysis of our gate protocols and determine relevant Kraus maps under typical noise sources to Rydberg-based platforms, such as: photon recoil, laser and thermal noise. Finally, we provide an overview of our online platform that provides users the opportunity to try out our gate-based emulator of the Rydberg quantum computer of the QRydDemo project and get familiar with its native gate operations.
