Quantum measurement incompatibility in subspaces
Roope Uola, Tristan Kraft, Sébastien Designolle +5
We consider the question of characterising the incompatibility of sets of high-dimensional quantum measurements. We introduce the concept of measurement incompatibility in subspace…
Optimal covariant quantum measurements
Erkka Haapasalo, Juha-Pekka Pellonpää
We discuss symmetric quantum measurements and the associated covariant observables modelled, respectively, as instruments and positive-operator-valued measures. The emphasis of thi…
Complementary observables in quantum mechanics
Jukka Kiukas, Pekka Lahti, Juha-Pekka Pellonpää +1
We review the notion of complementarity of observables in quantum mechanics, as formulated and studied by Paul Busch and his colleagues over the years. In addition, we provide furt…
Effective methods for constructing extreme quantum observables
Erkka Haapasalo, Juha-Pekka Pellonpaa
We study extreme points of the set of finite-outcome positive-operator-valued measures (POVMs) on finite-dimensional Hilbert spaces and particularly the possible ranks of the effec…
Number and phase: complementarity and joint measurement uncertainties
Pekka Lahti, Juha-Pekka Pellonpää, Jussi Schultz
We show that number and canonical phase (of a single mode optical field) are complementary observables. We also bound the measurement uncertainty region for their approximate joint…
Extreme commutative quantum observables are sharp
Teiko Heinosaari, Juha-Pekka Pellonpää
It is well known that, in the description of quantum observables, positive operator valued measures (POVMs) generalize projection valued measures (PVMs) and they also turn out be m…
