In this work we investigate the quantum noise properties of polarization vortices in connection with an intensity based Clauser-Horne-Shimony-Holt inequality for their spin-orbit separability. We evaluate the inequality for different input quantum states and the corresponding intensity fluctuations. The roles played by coherence and photon number squeezing provide a suitable framework for characterizing pure state spin-orbit entanglement. Structural inseparability of the spin-orbit mode…

Classical analog of quantum contextuality in spin-orbit laser modes
We experimentally observed the violation of Kujula-Dzhafarov noncontextuality inequalities by non-separable spin-orbit laser modes. Qubits are encoded on polarization and transverse modes of an
Entanglement beating in free space through spin–orbit coupling
TLDR
Using local Bell states engineered from classical vector vortex beams with non-separable degrees of freedom, the so-called classically entangled states, it is demonstrated that the entanglement evolves during propagation, oscillating between maximally entangled and product states (purely scalar).
Bell inequality violation and operator ordering in quantum theory
We investigate the role played by quantum operator ordering in the correlations that characterize two-photon polarization Bell measurements. The Clauser-Horne-Shimony-Holt (CHSH) criterion is
Quantum−like nonseparable structures in optical beams
When two or more degrees of freedom become coupled in a physical system, a number of observables of the latter cannot be represented by mathematical expressions separable with respect to the
Characterizing quantum channels with non-separable states of classical light
High-dimensional entanglement with spatial modes of light promises increased security and information capacity over quantum channels. Unfortunately, entanglement decays due to perturbations,
Experimental violation of a Bell-like inequality with optical vortex beams
Optical beams with topological singularities have a Schmidt decomposition. Hence, they display features typically associated with bipartite quantum systems; in particular, these classical beams can
Classical hypercorrelation and wave-optics analogy of quantum superdense coding
We report the first experimental realization of classical hypercorrelation, correlated simultaneously in every degree of freedom (DOF), from observing a Bell-type inequality violation in each DOF:
Classically high-dimensional correlation: simulation of high-dimensional entanglement.
TLDR
A classically high-dimensional correlation is reported, which is mathematically equivalent to its quantum counterparts and can be used to simulate the violations of the high- dimensional Bell inequalities.
Simulating Markovian quantum decoherence processes through an all-optical setup
TLDR
This work analytically obtain expressions for the $$l_1$$-norm of coherence and for the corresponding maximal coherence measure in terms of the initial state and decoherence parameters under which conditions such quantum coherence quantifiers exhibit the eternal freezing phenomenon.
Tripartite nonseparability in classical optics.
TLDR
This demonstration of a classical optical analogue of tripartite entanglement paves the path to novel optical applications inspired by multipartite quantum information protocols.
