论文摘要
最近，[Wang等人，Phys。 Rev. Research 1，033169（2019）]。资源理论中的基本对象是量子策略对，它们是量子通道的概括，提供了描述任意量子相互作用的框架。在本文中，我们提供了本资源理论中单次操作数量的半明确程序表征。然后，我们应用这些半明确计划来研究自适应策略在歧视和广义振幅阻尼通道的区分性蒸馏中赋予的优势。我们发现，通过自适应策略与非自适应策略可以实现的目标之间存在很大的差距。
Recently, the resource theory of asymmetric distinguishability for quantum strategies was introduced by [Wang et al., Phys. Rev. Research 1, 033169 (2019)]. The fundamental objects in the resource theory are pairs of quantum strategies, which are generalizations of quantum channels that provide a framework to describe an arbitrary quantum interaction. In the present paper, we provide semi-definite program characterizations of the one-shot operational quantities in this resource theory. We then apply these semi-definite programs to study the advantage conferred by adaptive strategies in discrimination and distinguishability distillation of generalized amplitude damping channels. We find that there are significant gaps between what can be accomplished with an adaptive strategy versus a non-adaptive strategy.
