Experimental investigation of nonclassicality in the simplest scenario via the degrees of freedom of light

João M. M. Gama, Guilherme T. C. Cruz, Massy Khoshbin +3

In this work, we experimentally investigate the classical-light emulation of different notions of nonclassicality in the simplest scenario. We implement this prepare-and-measure sc…

Simulation of depolarizing channel exploring maximally non separable spin-orbit mode

G. Tiago, V. S. Lamego, M. H. M. Passos +2

The Depolarizing channel is one of the most important noise models and constitutes a reliable benchmark for the quantum information field. In this work, we present a simple way to…

Feynman path sum approach for simulation of linear optics

Wagner F. Balthazar, Quinn M. B. Palmer, Alex. E. Jones +2

The Feynman path integral formalism has inspired the development of memory-efficient and parallelizable classical algorithms for simulating quantum computers. We adapt this approac…

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…

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…
