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…
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…
Perfect chiral quantum routing
Simone Cavazzoni, Giovanni Ragazzi, Paolo Bordone +1
Routing classical and quantum information is a fundamental task for quantum information technologies and processes. Here, we consider information encoded in the position of a quant…
Generalized phase estimation in noisy quantum gates
Giovanni Ragazzi, Simone Cavazzoni, Paolo Bordone +1
We examine metrological scenarios where the parameter of interest is encoded onto a quantum state through the action of a noisy quantum gate and investigate the ultimate bound to p…
