Contextuality in spin-orbit laser modes
M. H. M. Passos, W. F. Balthazar, J. Acacio de Barros +3
We experimentally observed the violation of Kujula-Dzhafarov noncontextuality inequalities by non-separable spin-orbit laser modes. Qubits are encoded on polarization and transvers…
Tripartite non-separability in classical optics
W. F. Balthazar, C. E. R. Souza, D. P. Caetano +3
It is possible to prepare classical optical beams which cannot be characterized by a tensor product of vectors describing each of their degrees of freedom. Here we report the exper…
Spin-orbit mode transfer via a classical analog of quantum teleportation
B. Pinheiro da Silva, M. Astigarreta Leal, C. E. R. Souza +2
We translate the quantum teleportation protocol into a sequence of coherent operations involving three degrees of freedom of a classical laser beam. The protocol, which we demonstr…
Topological phase structure of vector vortex beams
C. E. R. Souza, J. A. O. Huguenin, A. Z. Khoury
The topological phase acquired by vector vortex optical beams is investigated. Under local unitary operations on their polarization and transverse degrees of freedom, the vector vo…
Playing a quantum game on polarization vortices
A. R. C. Pinheiro, C. E. R. Souza, D. P. Caetano +3
The quantum mechanical approach to the well known prisoners dilemma, one of the basic examples to illustrate the concepts of Game Theory, is implemented with a classical optical re…
Optical parametric oscillation under injection of orbital angular momentum
B. Coutinho dos Santos, C. E. R. Souza, K. Dechoum +1
We present a theoretical model for the spatial mode dynamics of an optical parametric oscillator under injection of orbital angular momentum. This process is then interpreted in te…
