Spin-orbit implementation of Solovay-Kitaev decomposition of single-qubit channels
M. H. M. Passos, A. de Oliveira Junior, M. C. de Oliveira +2
The Solovay-Kitaev theorem allows us to approximate any single-qubit gate to arbitrary accuracy with a finite sequence of fundamental operations from a universal set of gates. Insp…
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…
Experimental investigation of enviroment--induced entanglement using an all--optical setup
M. H. M. Passos, W. F. Balthazar, A. Z. Khoury +3
We investigate the generation of entanglement between two non interacting qubits coupled to a common reservoir. An experimental setup was conceived to encode one qubit on the polar…
Two-qudit topological phase evolution under dephasing
L. E. Oxman, A. Z. Khoury, F. C. Lombardo +1
In this work, we study a bipartite system composed by a pair of entangled qudits coupled to an environment. Initially, we derive a master equation and show how the dynamics can be…
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…
