Observation of tunable Popescu-Rohrlich correlations through post-selection of a gaussian state
D. S. Tasca, S. P. Walborn, F. Toscano +1
We show that non-local Popescu-Rohrlich correlations can be observed in the post-selected results of binned position measurements on a two-party gaussian state. Our experiment is b…
Entropic Entanglement Criteria for Continuous Variables
S. P. Walborn, B. G. Taketani, A. Salles +2
We derive several entanglement criteria for bipartite continuous variable quantum systems based on the Shannon entropy. These criteria are more sensitive than those involving only…
An Entropic Einstein-Podolsky-Rosen Criterion
S. P. Walborn, A. Salles, R. M. Gomes +2
We propose an EPR inequality based on an entropic uncertainty relation for complementary continuous variable observables. This inequality is more sensitive than the previously esta…
Semiclassical Description of Wavepacket Revival
F. Toscano, R. O. Vallejos, D. A. Wisniacki
We test the ability of semiclassical theory to describe quantitatively the revival of quantum wavepackets --a long time phenomena-- in the one dimensional quartic oscillator (a Ker…
Propagation of transverse intensity correlations of a two-photon state
D. S. Tasca, S. P. Walborn, F. Toscano +2
The propagation of transverse spatial correlations of photon pairs through arbitrary first-order linear optical systems is studied experimentally and theoretically using the fracti…
Observation of a Non-local Optical Vortex
R. M. Gomes, A. Salles, F. Toscano +2
We report the observation of an optical vortex in the correlations of photons produced from spontaneous parametric down-conversion. The singularity appears in a non-local coordinat…
