The canonical phase measurement is pure
Teiko Heinosaari, Juha-Pekka Pellonpää
We show that the canonical phase measurement is pure in the sense that the corresponding positive operator valued measure (POVM) is extremal in the convex set of all POVMs. This me…

Extremal covariant positive operator valued measures: the case of a compact symmetry group
Claudio Carmeli, Teiko Heinosaari, Juha-Pekka Pellonpää +1
Given a unitary representation U of a compact group G and a transitive G-space , we characterize the extremal elements of the convex set of all U-covariant positive operator val…
