During the second phase, we focused on three tasks: (1) extending developments started in the first year, in particular the study of probabilistic transformations of quantum resources; (2) exploring new questions in the discrimination of quantum states and channels; (3) studying the asymptotic properties of quantum entanglement.With regards to point (1), this led to a new publication and an invited talk presentation at the Workshop on Quantum Information, Computation, and Foundations 2022 organized by Kyoto University.Point (2) led to several papers which are now undergoing review.Point (3) has led to two major publications, one which revealed significant differences between the theories of quantum entanglement and thermodynamics, and one which extended these ideas to quantum channels.

在第二阶段，我们主要做了三个方面的工作：（1）扩展第一年开始的研究，特别是量子资源的概率变换研究;（2）探索量子态和量子信道的鉴别中的新问题;（3）研究了量子纠缠的渐近性质，对于第（1）点，这导致了一个新的出版物，并在京都大学组织的2022年量子信息、计算和基础研讨会上受邀演讲。第（2）点导致了几篇论文，这些论文现在正在接受审查。第（3）点导致了两个主要出版物，一个揭示了量子纠缠理论和热力学理论之间的重大差异，另一个将这些想法扩展到量子通道。
