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…
Hole-spin qubits in germanium beyond the single-particle regime
Andrea Secchi, Gaia Forghieri, Paolo Bordone +3
The intense simulation efforts on hole-spin qubits in germanium have so far focused primarily on singly occupied quantum dots. Here, we theoretically investigate three-hole qubits…
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…
