Quantum ensembles and the statistical operator: a tutorial
Yinxiù Zhan, Matteo G. A. Paris
The main purpose of this tutorial is to elucidate in details what should be meant by ensemble of states in quantum mechanics, and to properly address the problem of discriminating,…
Joint quantum estimation of loss and nonlinearity in driven-dissipative Kerr resonators
Muhammad Asjad, Berihu Teklu, Matteo G. A. Paris
We address multiparameter quantum estimation for coherently driven nonlinear Kerr resonators in the presence of loss. In particular, we consider the realistic situation in which th…
Hybrid near-optimum binary receiver with realistic photon-number-resolving detectors
Michele N. Notarnicola, Matteo G. A. Paris, Stefano Olivares
We propose a near-optimum receiver for the discrimination of binary phase-shift-keyed coherent states employing photon-number-resolving detectors. The receiver exploits a discrimin…
Swift chiral quantum walks
Massimo Frigerio, Matteo G. A. Paris
A continuous-time quantum walk (CTQW) is sedentary if the return probability in the starting vertex is close to one at all times. Recent results imply that, when starting from a ma…
Noisy propagation of Gaussian states in optical media with finite bandwidth
Berihu Teklu, Matteo Bina, Matteo G. A. Paris
We address propagation and entanglement of Gaussian states in optical media characterised by non-trivial spectral densities. In particular, we consider environments with a finite b…
Perturbed graphs achieve unit transport efficiency without environmental noise
Simone Cavazzoni, Luca Razzoli, Paolo Bordone +1
Coherent transport of an excitation through a network corresponds to continuous-time quantum walk on a graph, and the transport properties of the system may be radically different…
Decoherence and classicalization of continuous-time quantum walks on graphs
Gabriele Bressanini, Claudia Benedetti, Matteo G. A. Paris
We address decoherence and classicalization of continuous-time quantum walks (CTQWs) on graphs. In particular, we investigate three different models of decoherence, and employ the…
Gravitational time dilation as a resource in quantum sensing
Carlo Cepollaro, Flaminia Giacomini, Matteo G. A. Paris
Atomic clock interferometers are a valuable tool to test the interface between quantum theory and gravity, in particular via the measurement of gravitational time dilation in the q…
Universality of the fully connected vertex in Laplacian continuous-time quantum walk problems
Luca Razzoli, Paolo Bordone, Matteo G. A. Paris
A fully connected vertex in a simple graph of order is a vertex connected to all the other vertices. Upon denoting by the Laplacian matrix of the graph, we pr…
Probing of nonlinear hybrid optomechanical systems via partial accessibility
V. Montenegro, M. G. Genoni, A. Bayat +1
Hybrid optomechanical systems are emerging as a fruitful architecture for quantum technologies. Hence, determining the relevant atom-light and light-mechanics couplings is an essen…
Feedback-assisted quantum search by continuous-time quantum walks
Alessandro Candeloro, Claudia Benedetti, Marco G. Genoni +1
We address the quantum search of a target node on a cycle graph by means of a quantum walk assisted by continuous measurement and feedback. Unlike previous spatial search approache…
