Optoelectronic devices like photodiodes based on single quantum dots are one of the new major fields of research for quantum computing, communication and sensing. In our work, we present our theoretical model and approaches using optoelectronic Bloch simulations to reproduce experimental results considering influences of a timing jitter between optical and electric pulses. Further, we use our model to validate quantum sensing methods and we show low frequency field simulations to estimate the electric properties of photodiodes, especially the RC-characteristics, to obtain a better understanding of the quantum dynamic and its electric control.
