Journal ArticleDOI
Are number and phase complementary observables
TL;DR: In this paper, various ways of characterizing the quantum optical number and phase as complementary observables were studied, and the optical number was shown to be complementary to the quantum phase.
Journal ArticleDOI
On vector bimeasures
Journal ArticleDOI
Normal covariant quantization maps
TL;DR: In this article, the authors consider the problem of quantizing complex valued functions defined on a locally compact topological group and generalize R. Werner's approach to prove the characterization of the associated normal covariant quantization maps.
Journal ArticleDOI
The norm-1-property of a quantum observable
TL;DR: The norm-1 property of a normalized positive operator measure X⟼E(X) has been investigated in this article, where it is shown that the measurement outcome probabilities for the values of such observables can be made arbitrarily close to one with suitable state preparations.
Journal ArticleDOI
Positive sesquilinear form measures and generalized eigenvalue expansions
TL;DR: In this article, positive sesquilinear form measures and their generalizations are considered with the aim of providing a framework for their generalized eigenvalue type expansions, and results range from a Naimark type dilation result to direct integral representations and a fairly concrete generalized Eigenvalue expansion for unbounded normal operators.
