Continuous-Variable Protocols in the Noisy-Storage Model

Fabian Furrer, Christian Schaffner, Stephanie Wehner

We present the first protocol for oblivious transfer that can be implemented with an optical continuous-variable system, and prove its security in the noisy-storage model. This mod…

Optimality of entropic uncertainty relations

Kais Abdelkhalek, René Schwonnek, Hans Maassen +5

The entropic uncertainty relation proven by Maassen and Uffink for arbitrary pairs of two observables is known to be non-optimal. Here, we call an uncertainty relation optimal, if…

Information-theoretical analysis of topological entanglement entropy and multipartite correlations

Kohtaro Kato, Fabian Furrer, Mio murao

A special feature of the ground state in a topologically ordered phase is the existence of large scale correlations depending only on the topology of the regions. These correlation…

Implementation of Continuous-Variable Quantum Key Distribution with Composable and One-Sided-Device-Independent Security Against Coherent Attacks

Tobias Gehring, Vitus Händchen, Jörg Duhme +5

Secret communication over public channels is one of the central pillars of a modern information society. Using quantum key distribution this is achieved without relying on the hard…

State-Dependent Approach to Entropic Measurement-Disturbance Relations

Patrick J. Coles, Fabian Furrer

Heisenberg's intuition was that there should be a tradeoff between measuring a particle's position with greater precision and disturbing its momentum. Recent formulations of this i…

Information-theoretical formulation of anyonic entanglement

Kohtaro Kato, Fabian Furrer, Mio Murao

Anyonic systems are modeled by topologically protected Hilbert spaces which obey complex superselection rules restricting possible operations. These Hilbert spaces cannot be decomp…

Position-Momentum Uncertainty Relations in the Presence of Quantum Memory

Fabian Furrer, Mario Berta, Marco Tomamichel +2

A prominent formulation of the uncertainty principle identifies the fundamental quantum feature that no particle may be prepared with certain outcomes for both position and momentu…

Min- and Max-Entropy in Infinite Dimensions

Fabian Furrer, Johan Aberg, Renato Renner

We consider an extension of the conditional min- and max-entropies to infinite-dimensional separable Hilbert spaces. We show that these satisfy characterizing properties known from…
