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…
Evading Vacuum Noise: Wigner Projections or Husimi Samples?
Christian R. Müller, Christian Peuntinger, Thomas Dirmeier +8
The accuracy in determining the quantum state of a system depends on the type of measurement performed. Homodyne and heterodyne detection are the two main schemes in continuous-var…
Extremal quantum states and their Majorana constellations
G. Bjork, A. B. Klimov, P. de la Hoz +3
The characterization of quantum polarization of light requires knowledge of all the moments of the Stokes variables, which are appropriately encoded in the multipole expansion of t…
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…
Atmospheric continuous-variable quantum communication
Bettina Heim, Christian Peuntinger, Nathan Killoran +4
We present a quantum communication experiment conducted over a point-to-point free-space link of 1.6 km in urban conditions. We study atmospheric influences on the capability of th…
Direct Schmidt number measurement of high-gain parametric down conversion
I. V. Dyakonov, P. R. Sharapova, T. Sh. Iskhakov +1
In this work we estimate the transverse Schmidt number for the bipartite bright squeezed vacuum state by means of second-order intensity correlation function measurement. Assuming…
