A Genuine Multipartite Bell Inequality for Device-independent Conference Key Agreement
Timo Holz, Hermann Kampermann, Dagmar Bruß
In this work, we present a new class of genuine multipartite Bell inequalities, that is particularly designed for multipartite device-independent (DI) quantum key distribution (QKD…
Comment on "Fully device-independent conference key agreement" [Phys. Rev. A 97, 022307 (2018)]
Timo Holz, Daniel Miller, Hermann Kampermann +1
In this manuscript we discuss the device-independent conference key agreement (DICKA) protocol [Phys. Rev. A 97, 022307 (2018)]. We show that the suggested honest implementation fa…
Parameter regimes for surpassing the PLOB bound with error-corrected qudit repeaters
Daniel Miller, Timo Holz, Hermann Kampermann +1
A potential quantum internet would open up the possibility of realizing numerous new applications, including provably secure communication. Since losses of photons limit long-dista…
Propagation of generalized Pauli errors in qudit Clifford circuits
Daniel Miller, Timo Holz, Hermann Kampermann +1
It is important for performance studies in quantum technologies to analyze quantum circuits in the presence of noise. We introduce an error probability tensor, a tool to track gene…
