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…
