# Entanglement: quantum or classical?

@article{Paneru2020EntanglementQO, title={Entanglement: quantum or classical?}, author={Dilip Paneru and Eliahu Cohen and Robert Fickler and Robert W. Boyd and Ebrahim Karimi}, journal={Reports on Progress in Physics}, year={2020}, volume={83} }

From its seemingly non-intuitive and puzzling nature, most evident in numerous EPR-like gedanken experiments to its almost ubiquitous presence in quantum technologies, entanglement is at the heart of modern quantum physics. First introduced by Erwin Schrödinger nearly a century ago, entanglement has remained one of the most fascinating ideas that came out of quantum mechanics. Here, we attempt to explain what makes entanglement fundamentally different from any classical phenomenon. To this end…

Single-particle entanglement: Quantum nonlocality or quantum contextuality?

- Physics

Two-photon interference: the Hong–Ou–Mandel effect

- PhysicsReports on progress in physics. Physical Society

The Hong-Ou-Mandel type of interference has so far been observed with massive particles, among others, such as electrons, atoms and plasmons, demonstrating the extent of this effect to larger and more complex quantum systems.

Nonlocal single particle steering generated through single particle entanglement

- PhysicsScientific reports

It is proved that the single-particle entanglement gives rise to truly nonlocal effects at two faraway places, which opens the possibility of using the single’s entangled state for implementing truly non local task.

Experimental tests of Multiplicative Bell Inequalities

Results of this study show that the two duality relations are quantitatively connected via entanglement, including the polarization coherence theorem, which is understood in the light of the roots of the new, to the best of the authors' knowledge, results in the classical optical domain.

Single-particle steering and nonlocality: The consecutive Stern-Gerlach experiments

Quantum correlations in separable multi-mode states and in classically entangled light

- PhysicsReports on progress in physics. Physical Society
- 2019

To unveil the quantum aspects of often classically perceived systems, this review focuses more in detail on quantum discordant correlations between the light modes and on nonseparability properties of optical vector fields leading to entanglement between different degrees of freedom of a single beam.

The classical-quantum boundary for correlations: Discord and related measures

One of the best signatures of nonclassicality in a quantum system is the existence of correlations that have no classical counterpart. Different methods for quantifying the quantum and classical…

Since Bell's theorem we know that quantum mechanics is incompatible with local hidden variable models, the phenomenon known as quantum nonlocality. However, in spite of steady progress over years,…

Exploring the Limits of Quantum Nonlocality with Entangled Photons

An experiment with single photonic qutrits provides evidence that no joint probability distribution describing the outcomes of all possible measurements—and, therefore, no non-contextual theory—can exist.

Relativistic independence bounds nonlocality

It is proved that theories with nonlocal correlations stronger than the quantum ones do not satisfy this notion of locality, and therefore, they either violate the underlying generalized uncertainty relations or allow experimenters to nonlocally tamper with the uncertainty relations of their peers.

It is well known that correlations predicted by quantum mechanics cannot be explained by any classical (local-realistic) theory. The relative strength of quantum and classical correlations is usually…
