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 exhibit entanglement. This classical entanglement can be

Thermodynamic cost of creating correlations
We investigate the fundamental limitations imposed by thermodynamics for creating correlations. Considering a collection of initially uncorrelated thermal quantum systems, we ask how much classical and quantum correlations can be obtained via a cyclic ...

Three-party pure quantum states are determined by two two-party reduced states
We can uniquely calculate almost all entangled state vectors of tripartite systems ABC if we know the reduced states of any two bipartite subsystems, e.g., of AB and of BC.

Bipartite Bell inequalities with three ternary-outcome measurements—from theory to experiments
We explore quantum nonlocality in one of the simplest bipartite scenarios. Several new facet-defining Bell inequalities for the $\{[3\;3\;3]\;[3\;3\;3]\}$ scenario are obtained with their quantum violations analyzed in details.

The photon identification loophole in EPRB experiments: computer models with single-wing selection
Recent Einstein-Podolsky-Rosen-Bohm experiments [M. Giustina et al. Phys. Rev. Lett. 115, 250401 (2015); L. K. Shalm et al. Phys. Rev. Lett. 115, 250402 (2015)] that claim to be loophole free are scrutinized.

Unlocking fermionic mode entanglement
Aside from other puzzling features of entanglement, it has been debated whether a physically meaningful notion of entanglement requires two (or more) particles as carriers of the correlated degrees-of-freedom, or if a single particle could be considered ...

Quantum limit for driven linear non-Markovian open-quantum-systems
The interplay between non-Markovian dynamics and driving fields in the survival of entanglement between two non-degenerate oscillators is considered here.

Detecting metrologically useful entanglement in the vicinity of Dicke states
We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measurement of the sensitivity.

Bohr against Bell: complementarity versus nonlocality
In this note we compare the views of Bohr (known as the Copenhagen interpretation of quantum mechanics) with the views of Bell: complementarity versus nonlocality.
