Phase conjugation and mode conversion in stimulated parametric down-conversion with orbital angular momentum: a geometrical interpretation
André G. de Oliveira, Marcelo F. Z. Arruda, Willamys C. Soares +5
We report on an experiment that investigates the spatial mode conversion in the process of parametric down-conversion seeded by a light beam in a superposition of orbital angular m…
Uncertainty Relations for coarse-grained measurements: an overview
Fabricio Toscano, Daniel S. Tasca, Łukasz Rudnicki +1
Uncertainty relations involving complementary observables are one of the cornerstones of quantum mechanics. Aside from their fundamental significance, they play an important role i…
Klyshko's Advanced-Wave Picture in Stimulated Parametric Down-Conversion with a Spatially Structured Pump Beam
M. F. Z. Arruda, W. C. Soares, S. P. Walborn +4
The advanced-wave picture is "... an intuitive treatment of two-photon correlation with the help of the concept of an effective field acting upon one of the two detectors and forme…
Mutually Unbiased Coarse-Grained Measurements of Two or More Phase-Space Variables
E. C. Paul, S. P. Walborn, D. S. Tasca +1
Mutual unbiasedness of the eigenstates of phase-space operators-such as position and momentum, or their standard coarse grained versions-exists only in the limiting case of infinit…
