Renyi熵的不可加性与Dvoretzky定理

Non-additivity of Renyi entropy and Dvoretzky's Theorem

Guillaume Aubrun, Stanislaw Szarek, Elisabeth Werner

摘要:

本文的目的是证明,对典型量子信道的最小输出p-Renyi熵的分析,实质上相当于应用关于高维凸体的几乎欧几里德截面的Dvoretzky定理的Milman版本。这在概念上简化了海登-温特反驳最小输出p-雷尼熵(p>1)的可加性猜想的(非构造性)论证。

英文摘要:

The goal of this note is to show that the analysis of the minimum output p-Renyi entropy of a typical quantum channel essentially amounts to applying Milman's version of Dvoretzky's Theorem about almost Euclidean sections of high-dimensional convex bodies. This conceptually simplifies the (nonconstructive) argument by Hayden-Winter disproving the additivity conjecture for the minimal output p-Renyi entropy (for p>1).
