Computing key rates for one-sided device-independent quantum key distribution
Andreas Bluhm, Gereon Koßmann, Martin Sandfuchs +3
The defining feature of one-sided device-independent quantum key distribution is its asymmetric trust model in which only one party is characterized. This scenario sets an interest…
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…
Device-Independent Randomness Amplification
Anatoly Kulikov, Simon Storz, Josua D. Schär +6
Successful realization of Bell tests has settled an 80-year-long debate, proving the existence of correlations which cannot be explained by a local realistic model. Recent experime…
Coherent attacks are stronger than collective attacks on DIQKD with random postselection
Martin Sandfuchs, Ramona Wolf
In a recent paper [Phys. Rev. Lett. 129, 050502 (2022)], the authors report on the implementation of a device-independent QKD protocol with random postselection, which was original…
Security of differential phase shift QKD from relativistic principles
Martin Sandfuchs, Marcus Haberland, V. Vilasini +1
The design of quantum protocols for secure key generation poses many challenges: On the one hand, they need to be practical concerning experimental realisations. On the other hand,…
