Privacy in networks of quantum sensors
Majid Hassani, Santiago Scheiner, Matteo G. A. Paris +1
We treat privacy in a network of quantum sensors where accessible information is limited to specific functions of the network parameters, and all other information remains private.…
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…
