Outline of Research at the Start

The project aims to develop a framework to describe physical phenomena which enable quantum advantages, focusing in particular on the resources of quantum processes. This will establish limitations on the processing of quantum information and the manipulation of quantum channels.

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.
