Spin-coherent quantum designs
Marcin Rudziński, Aaron Z. Goldberg, Andrei B. Klimov +2
Coherent states bridge the gap between quantum and classical physics, but their overcomplete and nonorthogonal nature makes it difficult to identify the minimal discrete set needed…
Covariant operator bases for continuous variables
A. Z. Goldberg, A. B. Klimov, G. Leuchs +1
Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow one to efficiently visualize quantum states in phase space. Here, we work…
Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ángel 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…
Dual form of the phase-space classical simulation problem in quantum optics
A. A. Semenov, A. B. Klimov
In quantum optics, nonclassicality of quantum states is commonly associated with negativities of phase-space quasiprobability distributions. We argue that the impossibility of any…
Unpolarized states and hidden polarization
P. de la Hoz, G. Bjork, A. B. Klimov +2
We capitalize on a multipolar expansion of the polarisation density matrix, in which multipoles appear as successive moments of the Stokes variables. When all the multipoles up to…
Multipolar hierarchy of efficient quantum polarization measures
P. de la Hoz, A. B. Klimov. G. Bjork, Y. -H. Kim +4
We advocate a simple multipole expansion of the polarisation density matrix. The resulting multipoles appear as successive moments of the Stokes variables and can be obtained from…
