Dynamical paths and universality in continuous variables open systems
Andrea Cazzaniga, Sabrina Maniscalco, Stefano Olivares +1
We address the dynamics of quantum correlations in continuous variable open systems and analyze the evolution of bipartite Gaussian states in independent noisy channels. In particu…
The canonical Naimark extension for the Pauli quantum roulette wheel
Carlo Sparaciari, Matteo G. A. Paris
We address measurement schemes where certain observables are chosen at random within a set of non-degenerate isospectral observables and then measured on repeated preparations of a…
Effects of classical environmental noise on entanglement and quantum discord
Claudia Benedetti, Fabrizio Buscemi, Paolo Bordone +1
We address the effect of classical noise on the dynamics of quantum correlations, entanglement and quantum discord, of two non-interacting qubits initially prepared in a Bell state…
Discording power of quantum evolutions
F. Galve, F. Plastina, M. G. A. Paris +1
We introduce the discording power of a unitary transformation, which assesses its capability to produce quantum discord, and analyze in detail the generation of discord by relevant…
The balance of quantum correlations for a class of feasible tripartite continuous variable states
Stefano Olivares, Matteo G. A. Paris
We address the balance of quantum correlations for continuous variable (CV) states. In particular, we consider a class of feasible tripartite CV pure states and explicitly prove tw…
Ancilla-Assisted Calibration of a Measuring Apparatus
G. Brida, L. Ciavarella, I. P. Degiovanni +6
A quantum measurement can be described by a set of matrices, one for each possible outcome, which represents the positive operator-valued measure (POVM) of the sensor. Efficient pr…
Non-Gaussian quantum discord for Gaussian states
Paolo Giorda, Michele Allegra, Matteo G. A. Paris
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 discor…
Qubit-assisted thermometry of a quantum harmonic oscillator
Matteo Brunelli, Stefano Olivares, Mauro Paternostro +1
We use the theory of quantum estimation in two different qubit-boson coupling models to demonstrate that the temperature of a quantum harmonic oscillator can be estimated with high…
A novel method to investigate how the spatial correlation of the pump beam affects the purity of polarization entangled states
Simone Cialdi, Davide Brivio, Andrea Tabacchini +2
We present an innovative method to address the relation between the purity of type-I polarization entangled states and the spatial properties of the pump laser beam. Our all-optica…
Two quantum Simpson's paradoxes
Matteo G. A. Paris
The so-called Simpson's "paradox", or Yule-Simpson (YS) effect, occurs in classical statistics when the correlations that are present among different sets of samples are reversed i…
Optical interferometry in the presence of large phase diffusion
Marco G. Genoni, Stefano Olivares, Davide Brivio +5
Phase diffusion represents a crucial obstacle towards the implementation of high precision interferometric measurements and phase shift based communication channels. Here we presen…
Non-classicality criteria from phase-space representations and information-theoretical constraints are maximally inequivalent
Alessandro Ferraro, Matteo G. A. Paris
We consider two celebrated criteria for defining the non-classicality of bipartite bosonic quantum systems, the first stemming from information theoretic concepts and the second fr…
Homodyne estimation of Gaussian quantum discord
Rémi Blandino, Marco G. Genoni, Jean Etesse +4
We address the experimental estimation of Gaussian quantum discord for two-mode squeezed thermal state, and demonstrate a measurement scheme based on a pair of homodyne detectors a…
