Metrological Benchmarking of Random Quantum Circuits
Simone Cavazzoni, Changhun Oh
Random circuit sampling is a leading approach to demonstrating quantum computational advantage, but benchmarking noisy implementations through linear cross-entropy requires costly…
From spectral structure to sensing limits in quantum thermometry
Youssef Aiache, Simone Cavazzoni, Abderrahim El Allati +2
The precision of a quantum thermometer is fundamentally constrained by the spectral structure of the probe itself, and a systematic mapping between the configurations of energy lev…
Quantum metrology of electric and magnetic dipole moments: ultimate limits and optimal regimes
Simone Cavazzoni, Paolo Bordone, Matteo G. A. Paris
The characterization of electric and magnetic dipole moments (EDM and MDM) in quantum systems is central to fundamental physics and quantum sensing. While EDM searches provide powe…
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…

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…
Coin dimensionality as a resource in quantum metrology involving discrete-time quantum walks
Simone Cavazzoni, Luca Razzoli, Giovanni Ragazzi +2
We address metrological problems where the parameter of interest is encoded in the internal degree of freedom of a discrete-time quantum walker, and provide evidence that coin dime…
Perturbed graphs achieve unit transport efficiency without environmental noise
Simone Cavazzoni, Luca Razzoli, Paolo Bordone +1
Coherent transport of an excitation through a network corresponds to continuous-time quantum walk on a graph, and the transport properties of the system may be radically different…
