Randomness from causally independent processes
Martin Sandfuchs, Carla Ferradini, Renato Renner
We consider a pair of causally independent processes, modelled as the tensor product of two channels, acting on a possibly correlated input to produce random outputs X and Y. We sh…

Defining Security in Quantum Key Distribution
Carla Ferradini, Martin Sandfuchs, Ramona Wolf +1
The security of quantum key distribution (QKD) is quantified by a parameter , which -- under well-defined physical assumptions -- can be bounded explicitly. This con…

Improved Two-source Extractors against Quantum Side Information
Jakob Miller, Martin Sandfuchs, Carla Ferradini
Two-source extractors aim to extract randomness from two independent sources of weak randomness. It has been shown that any two-source extractor which is secure against classical s…
