Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …

Schrödinger's cat is a Gedankenexperiment in quantum physics, in which an atomic decay
triggers the death of the cat. Because quantum physics allow atoms to remain in …

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 …

These notes originated out of a set of lectures in Quantum Optics and Quantum Information
given by one of us (MGAP) at the University of Napoli and the University of Milano. A quite …

We develop a resource theory for continuous-variable systems grounded on operations
routinely available within current quantum technologies. In particular, the set of free …

We present a theoretical demonstration on the generation of entangled coherent states and
of coherent state superpositions, with photon numbers and frequencies orders of magnitude …

This article presents a general discussion of several aspects of our present understanding of
quantum mechanics. The emphasis is put on the very special correlations that this theory …

Schrödinger's cat originates from the famous thought experiment querying the
counterintuitive quantum superposition of macroscopic objects. As a natural extension …

The so-called stellar formalism allows us to represent the non-Gaussian properties of single-
mode quantum states by the distribution of the zeros of their Husimi Q function in phase …
