The study of Gaussian states has arisen to a privileged position in contin- uous variable quantum information in recent years. This is due to vehemently pursued experimental realisations and a magnificently elegant mathematical framework. In this paper, we provide a brief, and hopefully didactic, exposition of Gaussian state quantum information and its contemporary uses, including sometimes omitted crucial details. After introducing the subject material and outlining the essential toolbox of…

Unified framework to determine Gaussian states in continuous-variable systems

Gaussian states are the backbone of quantum information protocols with continuous variable systems, whose power relies fundamentally on the entanglement between the different modes. In the case of

Gaussian quantum resource theories

It is shown that, under a few intuitive and physically-motivated assumptions on the set of free states, no Gaussian quantum resource can be distilled with Gaussian free operations, even when an unlimited supply of the resource state is available.

Quantum information in phase space

The results show a conversion of the negativity of local Wigner functions in mutual information and that the coherence for Gaussian states may be a witness for non-Markovian dynamics, evidencing the usefulness in several protocols in quantum thermodynamics.

Resource theory of quantum non-Gaussianity and Wigner negativity

A resource theory for continuous-variable systems grounded on operations routinely available within current quantum technologies, which lends itself to quantify both quantum non-Gaussianity and Wigner negativity as resources, depending on the choice of the free-state set.

Optimal secure quantum teleportation of coherent states of light

We investigate quantum teleportation of ensembles of coherent states of light with a Gaussian distributed displacement in phase space. Recently, the following general question has been addressed in

Gaussian entanglement revisited

We present a novel approach to the separability problem for Gaussian quantum states of bosonic continuous variable systems. We derive a simplified necessary and sufficient separability criterion for

Optimal measurements for quantum fidelity between Gaussian states and its relevance to quantum metrology

Quantum fidelity is a measure to quantify the closeness of two quantum states. In an operational sense, it is defined as the minimal overlap between the probability distributions of measurement

Measures and applications of quantum correlations

This work gives an overview of the current quest for a proper understanding and characterisation of the frontier between classical and quantum correlations (QCs) in composite states, and focuses on various approaches to define and quantify general QCs, based on different yet interlinked physical perspectives.

Hierarchy of continuous-variable quantum resource theories

It is shown that the maximal Gaussian coherence (where states and operations are required to be Gaussian) can be quantified analytically by the relative entropy, and it is proved that the equality of Gaussian non-uniformity and maximal Gaussia coherence is proved.



Entanglement in continuous-variable systems: recent advances and current perspectives

We review the theory of continuous-variable entanglement with special emphasis on foundational aspects, conceptual structures and mathematical methods. Much attention is devoted to the discussion of

Quantum discord for Gaussian states with non-Gaussian measurements

In recent years the paradigm based on entanglement as the unique measure of quantum correlations has been challenged by the rise of new correlation concepts, such as quantum discord, able to reveal

Gaussian quantum information

This review focuses on continuous-variable quantum information processes that rely on any combination of Gaussian states, Gaussian operations, and Gaussian measurements, including quantum communication, quantum cryptography, quantum computation, quantum teleportation, and quantum state and channel discrimination.

Measurement-induced disturbances and nonclassical correlations of Gaussian states

The findings provide a further confirmation of the genuinely quantum nature of general Gaussian states, yet they reveal that non-Gaussian measurements can play a crucial role for the optimized extraction and potential exploitation of classical and nonclassical correlations in GaRussian states.

Continuous variable methods in relativistic quantum information: characterization of quantum and classical correlations of scalar field modes in noninertial frames

We review a recently introduced unified approach to the analytical quantification of correlations in Gaussian states of bosonic scalar fields by means of Rényi-2 entropy. This allows us to obtain

Quantum Communication with Continuous Variables

The bottom line of this work is that a particular kind of entanglement, namely that based on continuous quantum variables, can be created relatively easily, and only squeezers and beam splitters are required to entangle arbitrarily many electromagnetic modes.

Quantum state majorization at the output of bosonic Gaussian channels.

It is proved that every output state of a phase-insensitive Gaussian channel is majorized by the output state corresponding to a coherent input, and that coherent states are the unique optimizers for the minimization of strictly concave output functionals.

Gaussian states in continuous variable quantum information

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 broad set of

Localised Systems in Relativistic Quantum Information

This thesis collects my own and collaborative work I have been involved with finding localised systems in quantum field theory that are be useful for quantum information. It draws from many well


It is a central trait of quantum information theory that there exist limitations to the free sharing of quantum correlations among multiple parties. Such monogamy constraints have been introduced in
