The area of information retrieval (IR) has taken on increasing importance in recent years. This field is now interest to large communities several application domains (security, medicine, aeronautics, etc.). IR studies find relevant from the semi-unstructured type data. As resources generated after search can be extensive quantity and different quality, it essential rank these results according...

Recently, impressive progress has been made in the study of non-Hermitian systems with parity-time symmetry, such as observations topological properties physical and criticality at exceptional points. A crucial aspect symmetric nonunitary dynamics is information flow between system environment. In this paper, we use quantity, distinguishability quantum states, to uniformly quantify low-dimensio...
