TL;DR: In this article, a metasurface-enhanced laser was proposed to produce high-purity OAM states with quantum numbers reaching l 1/ε 2/ε 3.

TL;DR: In this article, the authors use scalar beams in a time reversal approach to simulate the outcome of a quantum state tomography and exploit non-separability in classical vector beams as a means to treat the latter as a “classically entangled” state for illustrating QSTs directly.

TL;DR: This work realizes multidimensional entanglement transport through conventional single-mode fiber by entangling the spin-orbit degrees of freedom of a biphoton pair, passing the polarization (spin) photon down the SMF while accessing multiple orbital angular momentum subspaces with the other.

TL;DR: In this paper, the authors proposed a different scheme to perform optical sectioning of a sample based on the concept of induced coherence, where the varying reflectivity of the sample along the direction of propagation of an optical beam translates into changes of the degree of first-order coherence between two beams.

TL;DR: This work illustrates the general concept of enhancing coherence by modifying correlations for some typical simple systems, and answers the question of what is the best measure that quantifies the correlations that can be turned into coherence, and how much coherence can be extracted.
