TLDR
This work proposes several criteria that, it argues, should be applied to experimental entanglement verification procedures and demonstrates that not following these criteria will tend to result in overestimating the amount ofEntanglement generated in an experiment or in inferring entanglements when there is none.Abstract:
We give an overview of different types of entanglement that can be generated in experiments, as well as of various protocols that can be used to verify or quantify entanglement. We propose several criteria that, we argue, should be applied to experimental entanglement verification procedures. Explicit examples demonstrate that not following these criteria will tend to result in overestimating the amount of entanglement generated in an experiment or in inferring entanglement when there is none. We distinguish protocols meant to refute or eliminate hidden-variable models from those meant to verify entanglement.read more

The quantum internet
TL;DR: In this paper, the authors proposed a method for quantum interconnects, which convert quantum states from one physical system to those of another in a reversible manner, allowing the distribution of entanglement across the network and teleportation of quantum states between nodes.

Quantum information with Rydberg atoms
TL;DR: Rydberg atoms with principal quantum number $n⪢1$ have exaggerated atomic properties including dipole-dipole interactions that scale as ${n}^{4}$ and radiative lifetimes that scale at least{n}−3}$ as mentioned in this paper, and it was proposed a decade ago to implement quantum gates between neutral atom qubits.

TL;DR: The theoretical and experimental status quo of this very active field of quantum repeater protocols is reviewed, and the potentials of different approaches are compared quantitatively, with a focus on the most immediate goal of outperforming the direct transmission of photons.

Entanglement of Formation of an Arbitrary State of Two Qubits
TL;DR: In this article, an explicit formula for the entanglement of formation of a pair of binary quantum objects (qubits) as a function of their density matrix was conjectured.

Proposed Experiment to Test Local Hidden Variable Theories.
TL;DR: In this paper, a theorem of Bell, proving that certain predictions of quantum mechanics are inconsistent with the entire family of local hidden-variable theories, is generalized so as to apply to realizable experiments.

Experimental quantum teleportation
TL;DR: In this article, the authors demonstrated the feasibility of quantum teleportation over arbitrary distances of the state of a quantum system by using a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.

Quantum states with Einstein-Podolsky-Rosen correlations admitting a hidden-variable model
TL;DR: Any classically correlated state can be modeled by a hidden-variable theory and hence satisfies all generalized Bell's inequalities and the converse of this statement is false.
