Generation and detection of QKD symbols encoded in time and frequency
Today’s world is driven by huge amounts of critically important information, such as financial,industrial, medical, and military data. Secure exchange of the data is endangered by mathematicalprogress, increase in computational resources, and the developments in quantum computing.Quantum Key Distribution could provide a counter-method for all the mentioned threats as it isbased on fundamental laws of quantum physics instead of man-made algorithms. In thispresentation. I will discuss the progress towards experimental realization of a multidimensionalQKD protocol with time-frequency encoding. I will report on the generation and detection ofspectral and temporal symbols by means of fast electro-optic amplitude modulation combined withelectrical signal shaping and dispersive Fourier transformation. Influence of the RF bandwidth andtiming jitter on the dimensionality of the protocol will be described. Finally, I will discuss thepotential of our approach, possibilities of implementation within fiber optic network infrastructure,and opportunities for photonic integration.
