基于Hastings界的随机子空间的纠缠

Entanglement of random subspaces via the Hastings bound

Motohisa Fukuda, Christopher King

摘要:

最近Hastings证明了违反可加性猜想的随机酉信道的存在性。本文利用Hastings方法导出了二体系统随机子空间纠缠的新的界。作为应用,我们利用这些界证明了违反最小输出熵可加性的非单位信道的存在性。

英文摘要:

Recently Hastings proved the existence of random unitary channels which violate the additivity conjecture. In this paper we use Hastings' method to derive new bounds for the entanglement of random subspaces of bipartite systems. As an application we use these bounds to prove the existence of non-unital channels which violate additivity of minimal output entropy.
