Routing Qubits on Noisy Networks
Claudia Benedetti, Giovanni Ragazzi, Simone Cavazzoni +2
Robust quantum routing is essential for scalable quantum technologies. This paper investigates the resilience of routing protocols in network architectures designed for perfect, hi…
Quantum walks as a tool to design robust quantum batteries: the role of topology and chirality
Simone Cavazzoni, Giovanni Ragazzi, Paolo Bordone +1
The maximum work that can be extracted from a quantum battery is bounded by the ergotropy of the system, which is determined by the spectral properties of the Hamiltonian. In this…
Frequency estimation by frequency jumps
Simone Cavazzoni, Berihu Teklu, Matteo G. A. Paris
The frequency of a quantum harmonic oscillator cannot be determined through static measurement strategies on a prepared state, as the eigenstates of the system are independent of i…
Scalable Structure For Chiral Quantum Routing
Giovanni Ragazzi, Simone Cavazzoni, Claudia Benedetti +2
We address the problem of routing quantum and classical information from one sender to many possible receivers in a network. By employing the formalism of quantum walks, we describ…
Continuous-time quantum walks in the presence of a quadratic perturbation
Alessandro Candeloro, Luca Razzoli, Simone Cavazzoni +2
We address the properties of continuous-time quantum walks with Hamiltonians of the form , being the Laplacian matrix of the underlying graph and being t…
