„Generation and detection of QKD symbols encoded in time and frequency"
Abstract from Adam:
Today’s world is driven by huge amounts of critically important information, such as financial, industrial, medical, and military data. Secure exchange of data is endangered by mathematical progress, increment in computational resources, and developments in quantum computing. Quantum Key Distribution could provide a counter-method for all the mentioned threats as it is based on fundamental laws of quantum physics instead of man-made algorithms. In this presentation, I will discuss the progress towards the experimental realization of QKD systems, especially a multidimensional QKD protocol with time-frequency encoding. I will report on the generation and detection of spectral and temporal symbols by means of fast electro-optic amplitude modulation combined with electrical signal shaping and dispersive Fourier transformation. The influence of the RF bandwidth and timing jitter on the dimensionality of the protocol will be described. Finally, I will discuss the potential of our approach, possibilities of implementation within fibre optic network infrastructure, and opportunities for photonic integration.
This meeting is organized by the Quantum AI Foundation.
