Optimal covariant measurements: the case of a compact symmetry group and phase observables
Claudio Carmeli, Teiko Heinosaari, Juha-Pekka Pellonpää +1
We study various optimality criteria for quantum observables. Observables are represented as covariant positive operator valued measures and we consider the case when the symmetry…
Vector valued reproducing kernel Hilbert spaces and universality
C. Carmeli, E. De Vito, A. Toigo +1
This paper is devoted to the study of vector valued reproducing kernel Hilbert spaces. We focus on two aspects: vector valued feature maps and universal kernels. In particular we c…
Covariant quantum instruments
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
The structure of covariant instruments is studied and a general structure theorem is derived. A detailed characterization is given to covariant instruments in the case of an irredu…
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…
