Continuous variable multimode quantum states via symmetric group velocity matching
V. Roman-Rodriguez, B. Brecht, S. Kaali +4
Configurable and scalable continuous variable quantum networks for measurement-based quantum information protocols or multipartite quantum communication schemes can be obtained via…
Emergent complex quantum networks in continuous-variables non-Gaussian states
Mattia Walschaers, Nicolas Treps, Bhuvanesh Sundar +2
We use complex network theory to study a class of continuous-variable quantum states that present both multipartite entanglement and non-Gaussian statistics. We consider the interm…
Response of quantum spin networks to attacks
Bhuvanesh Sundar, Mattia Walschaers, Valentina Parigi +1
We investigate the ground states of spin models defined on networks that we imprint (e.g. non-complex random networks like Erdos-Renyi or complex networks like Watts-Strogatz, and…
Certification of non-Gaussian states with operational measurements
Ulysse Chabaud, Ganaël Roeland, Mattia Walschaers +4
We derive a theoretical framework for the experimental certification of non-Gaussian features of quantum states using double homodyne detection. We rank experimental non-Gaussian s…
Spatiotemporal entanglement in a noncollinear optical parametric amplifier
L. La Volpe, S. De, M. I. Kolobov +4
We theoretically investigate the generation of two entangled beams of light in the process of single-pass type-I noncollinear frequency degenerate parametric downconversion with an…
Conditional non-Gaussian quantum state preparation
Mattia Walschaers, Valentina Parigi, Nicolas Treps
We develop a general formalism, based on the Wigner function representation of continuous-variable quantum states, to describe the action of an arbitrary conditional operation on a…
Production and applications of non-Gaussian quantum states of light
A. I. Lvovsky, Philippe Grangier, Alexei Ourjoumtsev +3
This review covers recent theoretical and experimental efforts to extend the application of the continuous-variable quantum technology of light beyond "Gaussian" quantum states, su…
Gaussian states of continuous-variable quantum systems provide universal and versatile reservoir computing
Johannes Nokkala, Rodrigo Martínez-Peña, Gian Luca Giorgi +3
We establish the potential of continuous-variable Gaussian states of linear dynamical systems for machine learning tasks. Specifically, we consider reservoir computing, an efficien…
Quantum state engineering in arrays of nonlinear waveguides
David Barral, Mattia Walschaers, Kamel Bencheikh +4
In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin a…
Neural networks for detecting multimode Wigner-negativity
Valeria Cimini, Marco Barbieri, Nicolas Treps +2
The characterization of quantum features in large Hilbert spaces is a crucial requirement for testing quantum protocols. In the continuous variables encoding, quantum homodyne tomo…
Multimode Single-Pass Spatio-temporal Squeezing
Luca La Volpe, Syamsundar De, Tiphaine Kouadou +5
We present a single-pass source of broadband multimode squeezed light with potential application in quantum information and quantum metrology. The source is based on a type I param…
