Device-independent Quantum Key Distribution in the commuting operator framework
Gereon KoÃmann, René Schwonnek, Po-Chieh Liu +1
Device-independent quantum key distribution (DIQKD) is arguably the gold standard for secure quantum communication, as it aims to rely only on observed input-output statistics of a…

Device independent quantum key distribution with robust self-tests
Andreas Bluhm, Gereon KoÃmann, René Schwonnek
Device-independent quantum key distribution (DIQKD) provides a model of quantum key distribution with minimal assumptions and highly abstract theoretical building blocks. Although…

Routed Bell tests with arbitrarily many local parties
Gereon KoÃmann, Mario Berta, René Schwonnek
Device-independent quantum key distribution (DIQKD) promises cryptographic security based solely on observed quantum correlations, yet its implementation over long distances remain…
