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…
