TL;DR本文研究了 Schatten p - 范数下的量子失配概念,并利用二量子比特 Bell 对角态的正四面体限制优化得到了 1 - 范数下的分析表达式,该表达式等价于量子性的负性,并分析了其单调性。
Abstract
It has recently been pointed out that the geometric quantum discord, as
defined by the Hilbert-Schmidt norm (2-norm), is not a good measure of quantum
correlations, since it may increase under local reversible operations on the
unmeasured subsystem. Here, we revisit the geometric disco
