Wigner negativity and stellar rank for SU(1,1) states
A. B. Klimov, A. Muñoz, G. Leuchs +2
Quasiprobability distributions for systems endowed with SU(1,1) dynamical symmetry have received surprisingly little attention, despite the central role of this symmetry in two-pho…

Latent optical nonclassicality of conditionally prepared states
V. S. Kovtoniuk, A. B. Klimov, A. A. Semenov
The lack of information obtained from informationally incomplete quantum measurements can prevent the detection of quantum resources, such as optical nonclassicality. We develop a…

Rotation sensing at the ultimate limit
Aaron Z. Goldberg, Andrei B. Klimov, Gerd Leuchs +1
Conventional classical sensors are approaching their maximum sensitivity levels in many areas. Yet these levels still are far from the ultimate limits dictated by quantum mechanics…
