Extreme phase and rotated quadrature measurements
Juha-Pekka Pellonpää
We determine the extreme points of the convex set of covariant phase observables. Such extremals describe the best phase parameter measurements of laser light - the best in the sen…

The canonical phase measurement is pure
Teiko Heinosaari, Juha-Pekka Pellonpää
We show that the canonical phase measurement is pure in the sense that the corresponding positive operator valued measure (POVM) is extremal in the convex set of all POVMs. This me…

State reconstruction formulas for the s-distributions and quadratures
Jukka Kiukas, Juha-Pekka Pellonpää, Jussi Schultz
We consider the method of infinite matrix inversion in the context of quantum state reconstruction. Using this method we give rigorous proofs for reconstruction formulas for the Ca…
