The phase representation of covariant phase observables
Juha-Pekka Pellonpaa
Covariant phase observables are obtained by defining simple conditions for mappings from the set of phase wave functions (unit vectors of the Hardy space) to the set of phase proba…

On the structure of covariant phase observables
Juha-Pekka Pellonpaa
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 sequenc…

Are Number and Phase Complementary Observables?
Paul Busch, Pekka Lahti, Juha-Pekka Pellonpaa +1
We study various ways of characterising the quantum optical number and phase as complementary observables.
