Quantum state transfer via Bloch oscillations
Dario Tamascelli, Stefano Olivares, Stefano Rossotti +2
The realization of reliable quantum channels, able to transfer a quantum state with high fidelity, is a fundamental step in the construction of scalable quantum devices. In this pa…
Gaussian state interferometry with passive and active elements
Carlo Sparaciari, Stefano Olivares, Matteo G. A. Paris
We address precision of optical interferometers fed by Gaussian states and involving passive and/or active elements, such as beam splitters, photodetectors and optical parametric a…
The Lindley paradox in optical interferometry
Camillo Mauri, Matteo G. A. Paris
The so-called Lindley paradox is a counterintuitive statistical effect where the Bayesian and frequentist approaches to hypothesis testing give radically different answers, dependi…
Non-Markovian dynamics of single- and two-qubit systems interacting with Gaussian and non-Gaussian fluctuating transverse environments
Matteo A. C. Rossi, Matteo G. A. Paris
We address the interaction of single- and two-qubit systems with external fluctuating transverse fields and analyze in details the dynamical decoherence induced by Gaussian and non…
Non-Markovian continuous-time quantum walks on lattices with dynamical noise
Claudia Benedetti, Fabrizio Buscemi, Paolo Bordone +1
We address the dynamics of continuous-time quantum walks on one-dimensional disordered lattices inducing dynamical noise in the system. Noise is described as time-dependent fluctua…
Achieving the Landau bound to precision of quantum thermometry in systems with vanishing gap
Matteo G. A. Paris
We address estimation of temperature for finite quantum systems at thermal equilibrium and show that the Landau bound to precision , originally derived for a clas…
Phase noise in collective binary phase shift keying with Hadamard words
Marcin Jarzyna, Victoria Lipinska, Aleksandra Klimek +2
We analyze the effect of phase fluctuations in an optical communication scheme based on collective detection of sequences of binary coherent state symbols using linear optics and p…
Quantum phase communication channels in the presence of static and dynamical phase diffusion
Jacopo Trapani, Berihu Teklu, Stefano Olivares +1
We address quantum communication channels based on phase modulation of coherent states and analyze in details the effects of static and dynamical (stochastic) phase diffusion. We e…
Full quantum state reconstruction of symmetric two-mode squeezed thermal states via spectral homodyne detection
Simone Cialdi, Carmen Porto, Daniele Cipriani +2
We suggest and demonstrate a scheme to reconstruct the symmetric two-mode squeezed thermal states of spectral sideband modes from an optical parametric oscillator. The method is ba…
Experimental quantum tomography of a homodyne detector
Samuele Grandi, Alessandro Zavatta, Marco Bellini +1
We suggest and demonstrate a tomographic method to fully characterize homodyne detectors at the quantum level. The operator measure associated with the detector is expanded in the…
Ab-initio Quantum Enhanced Optical Phase Estimation Using Real-time Feedback Control
Adriano A. Berni, Tobias Gehring, Bo M. Nielsen +3
Optical phase estimation is a vital measurement primitive that is used to perform accurate measurements of various physical quantities like length, velocity and displacements. The…
Entangled quantum probes for dynamical environmental noise
Matteo A. C. Rossi, Matteo G. A. Paris
We address the use of entangled qubits as quantum probes to characterize the noise induced by complex environments. In particular, we show that a joint measurement on entangled pro…
Single- and two-mode quantumness at a beam splitter
Matteo Brunelli, Claudia Benedetti, Stefano Olivares +2
In the context of bipartite bosonic systems, two notions of classicality of correlations can be defined: P-classicality, based on the properties of the Glauber-Sudarshan P-function…
Nonlinearity and nonclassicality in a nanomechanical resonator
Berihu Teklu, Alessandro Ferraro, Mauro Paternostro +1
We address quantitatively the relationship between the nonlinearity of a mechanical resonator and the nonclassicality of its ground state. In particular, we analyze the nonclassica…
