Quantum measurements on finite dimensional systems: relabeling and mixing

By Erkka Haapasalo, Teiko Heinosaari and Juha-Pekka Pellonpää

Abstract

Concentrating on finite dimensional systems, we show that one can limit to extremal rank-1 POVMs if two simple procedures of mixing and relabeling are permitted. We demonstrate that any finite outcome POVM can be obtained from extremal rank-1 POVMs with these two procedures. In particular, extremal POVMs with higher rank are just relabelings of extremal rank-1 POVMs and their structure is therefore clarified.Comment: one new section in v
