Quantum concepts in optical polarization
Aaron Z. Goldberg, Pablo de la Hoz, Gunnar Bjork +4
We comprehensively review the quantum theory of the polarization properties of light. In classical optics, these traits are characterized by the Stokes parameters, which can be geo…
Contrast resolution of few-photon detectors
Mattias Jönsson, Gunnar Björk
We analyse the capability of distinguishing between different intensities in a monochromatic, pixellated image acquisition system at low light intensities. In practice, the latter…
SU(2) uncertainty limits
Saroosh Shabbir, Gunnar Björk
Although progress has been made recently in defining nontrivial uncertainty limits for the SU(2) group, a description of the intermediate states bound by these limits remains lacki…
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…
Classical distinguishability as an operational measure of polarization
G. Bjork, H. de Guise, A. B. Klimov +2
We put forward an operational degree of polarization that can be extended in a natural way to fields whose wave fronts are not necessarily planar. This measure appears as a distanc…
Non-monotonic dependence of projection probabilities as a function of distinguishability
Gunnar Björk, Saroosh Shabbir
Typically, quantum superpositions, and thus measurement projections of quantum states involving interference, decrease (or increase) monotonically as a function of increased distin…
