Non-Gaussian quantum states and where to find them

M Walschaers - PRX quantum, 2021 - APS
Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Nonclassical light and metrological power: An introductory review

KC Tan, H Jeong - AVS Quantum Science, 2019 - pubs.aip.org
In this review, the authors introduce the notion of quantum nonclassicality of light and the
role of nonclassicality in optical quantum metrology. The first part of this paper focuses on …

Resource theory of quantum non-Gaussianity and Wigner negativity

F Albarelli, MG Genoni, MGA Paris, A Ferraro - Physical Review A, 2018 - APS
We develop a resource theory for continuous-variable systems grounded on operations
routinely available within current quantum technologies. In particular, the set of free …

[HTML][HTML] Quantum non-Gaussianity of light and atoms

L Lachman, R Filip - Progress in Quantum Electronics, 2022 - Elsevier
Quantum non-Gaussian states of photons and phonons are conclusive and direct witnesses
of higher-than-quadratic nonlinearities in optical and mechanical processes. Moreover, they …

Convex resource theory of non-Gaussianity

R Takagi, Q Zhuang - Physical Review A, 2018 - APS
Continuous-variable systems realized in quantum optics play a major role in quantum
information processing, and it is also one of the promising candidates for a scalable …

Non-gaussianity as a signature of a quantum theory of gravity

R Howl, V Vedral, D Naik, M Christodoulou, C Rovelli… - PRX Quantum, 2021 - APS
Tabletop tests of quantum gravity (QG) have long been thought to be practically impossible.
However, remarkably, because of rapid progress in quantum information science (QIS), such …

Driven-dissipative preparation of entangled states in cascaded quantum-optical networks

K Stannigel, P Rabl, P Zoller - New Journal of Physics, 2012 - iopscience.iop.org
We study the dissipative dynamics and the formation of entangled states in driven cascaded
quantum networks, where multiple systems are coupled to a common unidirectional bath …

Comparative investigation of the freezing phenomena for quantum correlations under nondissipative decoherence

B Aaronson, R Lo Franco, G Adesso - Physical Review A—Atomic, Molecular …, 2013 - APS
We show that the phenomenon of frozen discord, exhibited by specific classes of two-qubit
states under local nondissipative decoherent evolutions, is a common feature of all known …

Quantifying non-Gaussianity for quantum information

MG Genoni, MGA Paris - Physical Review A—Atomic, Molecular, and Optical …, 2010 - APS
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 …

Stellar representation of non-Gaussian quantum states

U Chabaud, D Markham, F Grosshans - Physical Review Letters, 2020 - APS
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 …
