New Protocols for Conference Key and Multipartite Entanglement Distillation
Farzin Salek, Andreas Winter
We approach two interconnected problems of quantum information processing in networks: Conference key agreement and entanglement distillation, both in the so-called source model wh…
Bounding the joint numerical range of Pauli strings by graph parameters
Zhen-Peng Xu, René Schwonnek, Andreas Winter
The interplay between the quantum state space and a specific set of measurements can be effectively captured by examining the set of jointly attainable expectation values. This set…
Quantum soft-covering lemma with applications to rate-distortion coding, resolvability and identification via quantum channels
Touheed Anwar Atif, S. Sandeep Pradhan, Andreas Winter
We propose a quantum soft-covering problem for a given general quantum channel and one of its output states, which consists in finding the minimum rank of an input state needed to…
Invariant measures on p-adic Lie groups: the p-adic quaternion algebra and the Haar integral on the p-adic rotation groups
Paolo Aniello, Sonia L'Innocente, Stefano Mancini +3
We provide a general expression of the Haar measure that is, the essentially unique translation-invariant measure on a -adic Lie group. We then argue that this measure c…
Decoupling by local random unitaries without simultaneous smoothing, and applications to multi-user quantum information tasks
Pau Colomer, Andreas Winter
We show that a simple telescoping sum trick, together with the triangle inequality and a tensorisation property of expected-contractive coefficients of random channels, allow us to…
Continuity bounds on observational entropy and measured relative entropies
Joseph Schindler, Andreas Winter
We derive a measurement-independent asymptotic continuity bound on the observational entropy for general POVM measurements, making essential use of its property of bounded concavit…
