Coexistence of qubit effects
Peter Stano, Daniel Reitzner, Teiko Heinosaari
We characterize all coexistent pairs of qubit effects. This gives an exhaustive description of all pairs of events allowed, in principle, to occur in a single qubit measurement. Th…

Approximate Joint Measurability of Spin Along Two Directions
Teiko Heinosaari, Peter Stano, Daniel Reitzner
We study the existence of jointly measurable POVM approximations to two non-commuting sharp spin observables. We compare two different ways to specify optimal approximations.
