本文进一步完善了最近由[Wang等，Phys.]提出的量子策略的非对称可区分性资源理论。修订研究1,033169(2019年)]。资源理论中的基本对象是量子策略对，它们是量子通道的泛化，提供了描述任意量子相互作用的框架。在这个资源理论中，我们给出了单次作业量的半定程序刻画。然后，我们应用这些半定规划来研究自适应策略在广义幅度衰减通道的识别和可分辩性提升中所带来的优势。
This paper contributes further to the resource theory of asymmetric distinguishability for quantum strategies, as introduced recently 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 any arbitrary quantum interaction. 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.
