Outline of Annual Research Achievements

We have developed the theory of quantum resources in various settings, introduced new approaches to study their manipulation, and discovered new limitations on their processing. We introduced the framework of "virtual resource distillation" that integrates the power of classical postprocessing to enhance the ability to distill resources from quantum states and channels. Furthermore, we comprehensively characterised how the resource of postselection can enhance information processing capabilities in quantum state discrimination.
