Experimental investigation of discord in spin-orbit X-states
V. S. Lamego, D. G. Braga, W. F. Balthazar +1
We perform an experimental investigation of Quantum Discord with Spin-Orbit X-states. These states are prepared through the incoherent superposition of different laser beans, where…
Spin-orbit maximally discordant mixed states
D. G. Braga, I. Fonseca, W. F. Balthazar +2
We introduce a proposal to prepare spin-obit maximally discordant mixed states by a linear optical circuit, with quantum bits (qubits) encoded in the polarization and transverse mo…
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…
Optical simulation of a quantum thermal machine
M. H. M. Passos, Alan C. Santos, Marcelo S. Sarandy +1
We introduce both a theoretical and an experimental scheme for simulating a quantum thermal engine through an all-optical approach, with the behavior of the working substance and t…
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…
Non-Markovianity through quantum coherence in an all-optical setup
M. H. M. Passos, P. C. Obando, W. F. Balthazar +3
We propose an all-optical experiment to quantify non-Markovianity in an open quantum system through quantum coherence of a single quantum bit. We use an amplitude damping channel i…
