Continuous-time quantum walks on dynamical percolation graphs
Claudia Benedetti, Matteo A. C. Rossi, Matteo G. A. Paris
We address continuous-time quantum walks on graphs in the presence of time- and space-dependent noise. Noise is modeled as generalized dynamical percolation, i.e. classical time-de…
Non-Markovianity is not a resource for quantum spatial search on a star graph subject to generalized percolation
Matteo A. C. Rossi, Marco Cattaneo, Matteo G. A. Paris +1
Continuous-time quantum walks may be exploited to enhance spatial search, i.e., for finding a marked element in a database structured as a complex network. However, in practical im…
Non-Markovian evolution of a two-level system interacting with a fluctuating classical field via dipole interaction
Samaneh Hesabi, Davood Afshar, Matteo G. A. Paris
We address memory effects in the dynamics of a two-level open quantum system interacting with a classical fluctuating field via dipole interaction. In particular, we study the back…
Homodyne tomography with homodyne-like detection
Stefano Olivares, Alessia Allevi, Giovanni Caiazzo +2
We show that data from homodyne-like detection based on photon-number-resolving (PNR) detectors may be effectively exploited to reconstruct quantum states of light using the tomogr…
The walker speaks its graph: global and nearly-local probing of the tunnelling amplitude in continuous-time quantum walks
Luigi Seveso, Claudia Benedetti, Matteo G. A. Paris
We address continuous-time quantum walks on graphs, and discuss whether and how quantum-limited measurements on the walker may extract information on the tunnelling amplitude betwe…
Qubit systems subject to unbalanced random telegraph noise: quantum correlations, non-Markovianity and teleportation
Simone Daniotti, Claudia Benedetti, Matteo G. A. Paris
We address the dynamics of quantum correlations in a two-qubit system subject to unbalanced random telegraph noise (RTN) and discuss in details the similarities and the differences…
Quantum spatial search on graphs subject to dynamical noise
Marco Cattaneo, Matteo A. C. Rossi, Matteo G. A. Paris +1
We address quantum spatial search on graphs and its implementation by continuous-time quantum walks in the presence of dynamical noise. In particular, we focus on search on the com…
Quantum probes for quantum wells
Ilaria Pizio, Shivani Singh, C. M. Chandrashekar +1
We seek for the optimal strategy to infer the width of an infinite potential wells by performing measurements on the particle(s) contained in the well. In particular, we addres…
Quantum thermometry by single-qubit dephasing
Sholeh Razavian, Claudia Benedetti, Matteo Bina +2
We address the dephasing dynamics of a qubit as an effective process to estimate the temperature of its environment. Our scheme is inherently quantum, since it exploits the sensiti…
Homodyning the of Gaussian states
Stefano Olivares, Simone Cialdi, Matteo G. A. Paris
We suggest a method to reconstruct the zero-delay-time second-order correlation function of Gaussian states using a single homodyne detector. To this purpose, we have…
Back and forth from Fock space to Hilbert space: a guide for commuters
Andrea Beggi, Ilaria Siloi, Claudia Benedetti +4
Quantum states of systems made of many identical particles, e.g. those described by Fermi-Hubbard and Bose-Hubbard models, are conveniently depicted in the Fock space. However, in…
Trade-off between information and disturbance in qubit thermometry
Luigi Seveso, Matteo G. A. Paris
We address the trade-off between information and disturbance in qubit thermometry from the perspective of quantum estimation theory. Given a quantum measurement, we quantify inform…
Resource theory of quantum non-Gaussianity and Wigner negativity
Francesco Albarelli, Marco G. Genoni, Matteo G. A. Paris +1
We develop a resource theory for continuous-variable systems grounded on operations routinely available within current quantum technologies. In particular, the set of free operatio…
Phase estimation with squeezed single photons
Stefano Olivares, Maria Popovic, Matteo G. A. Paris
We address the performance of an interferometric setup in which a squeezed single photon interferes at a beam splitter with a coherent state. Our analysis in based on both the quan…
