High-fidelity controlled-phase gates for distinguishable quantum walkers via extended interactions
Gaia Forghieri, Matteo G. A. Paris
We investigate the implementation of controlled-phase (CP) gates with quantum walks in a dual-rail encoding through the use of interacting particles. While previous proposals have…
Thermometry with multilevel transmon probes
Antonio Mandarino, Matteo G. A. Paris, Claudia Benedetti
Superconducting transmon systems are promising platforms for nanoscale thermometry due to their high sensitivity to environmental fluctuations. Their intrinsic anharmonicity, which…
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…
Engineering entanglement and transport in interacting quantum walks with tailored potentials
Gaia Forghieri, Matteo G. A. Paris
Controlling the interplay between particle propagation and quantum correlation generation is a central challenge in quantum transport. Here, we investigate two distinguishable cont…
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…
