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…
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…
Critical metrology of minimally accessible anisotropic spin chains
Marco Adani, Simone Cavazzoni, Berihu Teklu +2
We address quantum metrology in critical spin chains with anisotropy and Dzyaloshinskii-Moriya (DM) interaction, and show how local and quasi-local measurements may be exploited to…
Optimizing topology for quantum probing with discrete-time quantum walks
Simone Cavazzoni, Paolo Bordone, Matteo G. A. Paris
Discrete-time quantum walk (DTQW) represents a convenient mathematical framework for describing the motion of a particle on a discrete set of positions when this motion is conditio…
Characterization of partially accessible anisotropic spin chains in the presence of anti-symmetric exchange
Simone Cavazzoni, Marco Adani, Paolo Bordone +1
We address quantum characterization of anisotropic spin chains in the presence of antisymmetric exchange, and investigate whether the Hamiltonian parameters of the chain may be est…
