Journal ArticleDOI
Bell-like inequality for the spin-orbit separability of a laser beam
TL;DR: In this article, an inequality criterion for the nonseparability of the spin-orbit degrees of freedom of a laser beam is proposed, and the inequality is discussed in both the classical and quantum domains.
Journal ArticleDOI
Quantum key distribution without a shared reference frame
C. E. R. Souza,C. V. S. Borges,Antonio Z. Khoury,José Augusto Oliveira Huguenin,Leandro Aolita,Stephen P. Walborn +5 more
TL;DR: In this article, a simple quantum-key distribution experiment was conducted in which Alice and Bob do not need to share a common polarization direction in order to send information, and Logical qubits are encoded into nonseparable states of polarization and first-order transverse spatial modes of the same photon.
Journal ArticleDOI
Topological phase for spin-orbit transformations on a laser beam.
TL;DR: An experimental demonstration of the topological phase associated with the SO(3) representation in terms of maximally entangled states for polarization and spatial mode transformations of a laser beam is provided.
Journal ArticleDOI
Orbital angular momentum exchange in an optical parametric oscillator
TL;DR: In this paper, the orbital angular momentum transfer from pump to down-converted beams in a type-II optical parametric oscillator was investigated and Cavity and anisotropy effects were investigated and demonstrated to play a central role in the transverse mode dynamics.
Journal ArticleDOI
Conservation of orbital angular momentum in stimulated down-conversion
D. P. Caetano,Marcelo P. Almeida,P. H. Souto Ribeiro,José Augusto Oliveira Huguenin,B. Coutinho dos Santos,Antonio Z. Khoury +5 more
TL;DR: In this article, the orbital angular momentum is conserved for spontaneous down-conversion through cavity-free stimulated emission, and it is also conserved when twin photons are taken individually.
