OPTIMAL COVARIANT MEASUREMENTS: THE CASE OF A COMPACT SYMMETRY GROUP AND PHASE OBSERVABLES

Abstract

Abstract. 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 group is compact. Phase observables are examined as an example. 1.

Optimal covariant quantum measurements

Erkka Haapasalo, Juha-Pekka Pellonpää

Abstract We discuss symmetric quantum measurements and the associated covariant observables modelled, respectively, as instruments and positive-operator-valued measures. The emphasis of this work are the optimality properties of the measurements, namely, extremality, informational completeness, and the rank-1 property which contrast the complementary class of (rank-1) projection-valued measures. The first half of this work concentrates solely on finite-outcome measurements symmetric w.r.t. finite groups where we derive exhaustive characterizations for the pointwise Kraus-operators of covariant instruments and necessary and sufficient extremality conditions using these Kraus-operators. We motivate the use of covariance methods by showing that observables covariant with respect to symmetric groups contain a family of representatives from both of the complementary optimality classes of observables and show that even a slight deviation from a rank-1 projection-valued measure can yield an extreme informationally complete rank-1 observable. The latter half of this work derives similar results for continuous measurements in (possibly) infinite dimensions. As an example we study covariant phase space instruments, their structure, and extremality properties.

Extremal covariant positive operator valued measures: The case of a compact symmetry group

Claudio Carmeli, Teiko Heinosaari, Juha-Pekka Pellonpää +1 more

Given a unitary representation U of a compact group G and a transitive G-space Ω, we characterize the extremal elements of the convex set of all U-covariant positive operator valued measures.

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

ON THE STRUCTURE OF COVARIANT PHASE OBSERVABLES

Juha-Pekka Pellonpää

Abstract. We study the mathematical structure of covariant phase observables. Such an observable can alternatively be expressed as a phase matrix, as a sequence of unit vectors, as a sequence of phase states, or as an equivalent class of covariant trace-preserving operations. Covariant generalized operator measures are defined by structure matrices which form a W ∗-algebra with phase matrices as its subset. The properties of the Radon-Nikod´ym derivatives of phase probability measures are studied. 1.

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.
