Continuous Variable Quantum Key Distribution: Finite-Key Analysis of Composable Security against Coherent Attacks
Fabian Furrer, Torsten Franz, Mario Berta +4
We provide a security analysis for continuous variable quantum key distribution protocols based on the transmission of squeezed vacuum states measured via homodyne detection. We em…
The Smooth Entropy Formalism for von Neumann Algebras
Mario Berta, Fabian Furrer, Volkher B. Scholz
We discuss information-theoretic concepts on infinite-dimensional quantum systems. In particular, we lift the smooth entropy formalism as introduced by Renner and collaborators for…
Bound Molecules in an Interacting Quantum Walk
Andre Ahlbrecht, Andrea Alberti, Dieter Meschede +3
We investigate a system of two atoms in an optical lattice, performing a quantum walk by state-dependent shift operations and a coin operation acting on the internal states. The at…
Disordered Quantum Walks in one lattice dimension
Andre Ahlbrecht, Volkher B. Scholz, Albert H. Werner
We study a spin-1/2-particle moving on a one dimensional lattice subject to disorder induced by a random, space-dependent quantum coin. The discrete time evolution is given by a fa…
