Intrinsic unsharpness and approximate repeatability of quantum measurements
C. Carmeli, T. Heinonen, A. Toigo
The intrinsic unsharpness of a quantum observable is studied by introducing the notion of resolution width. This quantification of accuracy is shown to be closely connected with th…

On the coexistence of position and momentum observables
C. Carmeli, T. Heinonen, A. Toigo
We investigate the problem of coexistence of position and momentum observables. We characterize those pairs of position and momentum observables which have a joint observable.

Covariant fuzzy observables and coarse-graining
T. Heinonen, P. Lahti, K. Ylinen
A fuzzy observable is regarded as a smearing of a sharp observable, and the structure of covariant fuzzy observables is studied. It is shown that the covariant coarse-grainings of…
