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…

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…

Experimental investigation of the dynamics of entanglement: Sudden death, complementarity, and continuous monitoring of the environment
A. Salles, F. Melo, M. P. Almeida +4
We report on an experimental investigation of the dynamics of entanglement between a single qubit and its environment, as well as for pairs of qubits interacting independently with…
