Extremal covariant positive operator valued measures

Giulio Chiribella, Giacomo Mauro D’Ariano

We consider the convex set of positive operator valued measures (POVM) which are covariant under a finite dimensional unitary projective representation of a group. We derive a general characterization for the extremal points, and provide bounds for the ranks of the corresponding POVM densities, also relating extremality to uniqueness and stability of optimized measurements. Examples of applications are given.

Extremal covariant quantum operations and positive operator valued measures

Giacomo Mauro D’Ariano

We consider the convex sets of QO’s (quantum operations) and POVM’s (positive operator valued measures) which are covariant under a general finite-dimensional unitary representation of a group. We derive necessary and sufficient conditions for extremality, and give general bounds for ranks of the extremal POVM’s and QO’s. Results are illustrated on the basis of simple examples.

Extremal covariant measurements

Giulio Chiribella, Giacomo Mauro D’Ariano

We characterize the extremal points of the convex set of quantum measurements that are covariant under a finite-dimensional projective representation of a compact group, with action of the group on the measurement probability space which is generally nontransitive. In this case the POVM density is made of multiple orbits of positive operators, and, in the case of extremal measurements, we provide a bound for the number of orbits and for the rank of POVM elements. Two relevant applications are considered, concerning state discrimination with mutually unbiased bases and the maximization of the mutual information.

Extreme covariant quantum observables in the case of an Abelian symmetry group and a transitive value space

Erkka Haapasalo, Juha-Pekka Pellonpää

We represent quantum observables as normalized positive operator valued measures and consider convex sets of observables which are covariant with respect to a unitary representation of a locally compact Abelian symmetry group G. The value space of such observables is a transitive G-space. We characterize the extreme points of covariant observables and also determine the covariant extreme points of the larger set of all quantum observables. The results are applied to position, position difference, and time observables.

EXTREMAL COVARIANT MEASUREMENTS

Giulio Chiribella, Giacomo

Abstract. We characterize the extremal points of the convex set of quantum measurements that are covariant under a finite-dimensional projective representation of a compact group, with action of the group on the measurement probability space which is generally non-transitive. In this case the POVM density is made of multiple orbits of positive operators, and, in the case of extremal measurements, we provide a bound for the number of orbits and for the rank of POVM elements. Two relevant applications are considered, concerning state discrimination with mutually unbiased bases and the maximization of the mutual information. 1. introduction A fundamental issue in the theory of quantum information [1] is the investigation of the ultimate precision limits for extracting classical information from a quantum system. Indeed, when the information is encoded on quantum states, its read-out suffers the intrinsically quantum limitation of discriminating among nonorthogonal states. One then need to optimize the discrimination with respect to a given optimality
