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…
Tripartite State Characterization via Activated Bipartite Entanglement
L. G. E. Arruda, W. F. Balthazar, M. V. Moreira +3
We propose a procedure to identify and classify genuine tripartite entanglement in pure 3-qubit states via the Activated Bipartite Entanglement (ABE), which is defined here as the…
Equivalence regimes for geometric quantum discord and local quantum uncertainty
Oscar Cordero, Arturo Villegas, Juan-Rafael Alvarez +3
The concept of quantum discord aims at unveiling quantum correlations that go beyond those described by entanglement. Its original formulation [J. Phys. A 34, 6899 (2001); Phys. Re…
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…
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…
