Generalized quantum-classical correspondence for random walks on graphs
Massimo Frigerio, Claudia Benedetti, Stefano Olivares +1
We introduce a minimal set of physically motivated postulates that the Hamiltonian H of a continuous-time quantum walk should satisfy in order to properly represent the quantum cou…
Scattering as a quantum metrology problem: a quantum walk approach
Francesco Zatelli, Claudia Benedetti, Matteo G. A. Paris
We address the scattering of a quantum particle by a one-dimensional barrier potential over a set of discrete positions. We formalize the problem as a continuous-time quantum walk…
Quantum probing beyond pure dephasing
Dario Tamascelli, Claudia Benedetti, Heinz-Peter Breuer +1
Quantum probing is the art of exploiting simple quantum systems interacting with a complex environment to extract precise information about some environmental parameters, e.g. the…
Experimental realization of local-to-global noise transition in a two-qubit optical simulator
Claudia Benedetti, Valeria Vento, Stefano Olivares +2
We demonstrate the transition from local to global noise in a two-qubit all-optical quantum simulator subject to classical random fluctuations. Qubits are encoded in the polarizati…
Two-qubit quantum probes for the temperature of an Ohmic environment
Francesca Gebbia, Claudia Benedetti, Fabio Benatti +3
We address a particular instance where open quantum systems may be used as quantum probes for an emergent property of a complex system, as the temperature of a thermal bath. The in…
Quantum-classical dynamical distance and quantumness of quantum walks
Valentina Gualtieri, Claudia Benedetti, Matteo G. A. Paris
We introduce a fidelity-based measure to quantify the differences between the dynamics of classical (CW) and quantum (QW) walks over a graph. We provide u…
