This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

We report an experimental realization of Maxwell's demon in a photonic setup. We show that
a measurement at the few-photons level followed by a feed-forward operation allows the …

The ability to manipulate light at the level of single photons, its elementary excitation quanta,
has recently made it possible to produce a rich variety of tailor-made quantum states and …

Entanglement between quantum and classical objects is of special interest in the context of
fundamental studies of quantum mechanics and potential applications for quantum …

Noise is the price to pay when trying to clone or amplify arbitrary quantum states. However,
the quantum noise associated with linear phase-insensitive amplifiers can be avoided by …

We address the quantification of non-Gaussianity (nG) of states and operations in
continuous-variable systems and its use in quantum information. We start by illustrating in …

We theoretically investigate the performance of multiphoton catalysis applied on the two-
mode squeezed state by examining the entropy of entanglement, logarithmic negativity …

We study a coherent superposition t â+ r ↠of field annihilation and creation operators
acting on continuous variable systems and propose its application for quantum state …

We investigate how the entanglement properties of a two-mode state can be improved by
performing a coherent superposition operation t â+ r ↠of photon subtraction and …

The non-Gaussian operations effected by adding or subtracting a photon on entangled
optical beams emerging from a parametric down-conversion process have been suggested …
