Hi all, Tomorrow Anna Efimova will tell us about her semesterthesis with Ramona. See below for the abstract. The talk will take place at 2pm in HIT E 41.1 or on Zoom: https://ethz.zoom.us/j/362994444. Best, Ladina %%%% Today I'm going to tell you about Quantum Random Number Generators which can be used in different areas from physics experiments to commercial purposes. However, true randomness is not always understood correctly. We are going to consider different scenarios of device imperfections and emphasize some important details of the mathematical description of different protocols.
