Continuous variable quantum computation with spatial degrees of freedom of photons
D. S. Tasca, R. M. Gomes, F. Toscano +2
We discuss the use of the transverse spatial degrees of freedom of photons propagating in the paraxial approximation for continuous variable information processing. Given the wide…
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…
Quantum teleportation in superconducting charge qubits
R. M. Gomes, W. B. Cardoso, A. T. Avelar +1
In this paper we propose a scheme to implement a quantum teleportation based on the current experimental design [Nature (London) 431, 162 (2004); ibid 445, 515 (2007)] in which sup…
