Wigner negativity and stellar rank for SU(1,1) states
A. B. Klimov, A. Muñoz, G. Leuchs +3
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…

The quantum sky of Majorana stars
L. L. Sanchez-Soto, A. B. Klimov, A. Z. Goldberg +1
Majorana stars, the spin coherent states that are orthogonal to a spin- state, offer an elegant method to visualize quantum states. This representation offers deep insights…

Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ãngel S Sanz +8
Even the most classical states are still governed by quantum theory. A number of physical systems can be described by their Majorana constellations of points on the surface of a sp…
