Lithium niobate (LiNbO3) on insulator (LNOI) is a promising material platform for integrated
photonics due to single crystal LiNbO3 film's wide transparent window, high refractive index …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

More than 50 years ago, John Bell proved that no theory of nature that obeys locality and
realism can reproduce all the predictions of quantum theory: in any local-realist theory, the …

Superposition, entanglement and non-locality constitute fundamental features of quantum
physics. The fact that quantum physics does not follow the principle of local causality,–can …

Although there are many textbooks that deal with the formal apparatus of quantum
mechanics (QM) and its application to standard problems, none take into account the …

Single-photon detectors at near-infrared wavelengths with high system detection efficiency
(> 90%), low dark count rate (< 1 cps), low timing jitter (< 100 ps) and short reset time (< 100 …

The violation of a Bell inequality is an experimental observation that forces the
abandonment of a local realistic viewpoint—namely, one in which physical properties are …

This Colloquium examines the field of the Einstein, Podolsky, and Rosen (EPR) gedanken
experiment, from the original paper of Einstein, Podolsky, and Rosen, through to modern …

Using independent sources one can realize an ''event-ready''Bell–Einstein-Podolsky-Rosen
experiment in which one can measure directly the probabilities of the various outcomes …

In spite of the impressive predictive power and strong mathematical structure of quantum
mechanics, the theory has always suffered from important conceptual problems. Some of …
