Model-aware reinforcement learning for high-performance Bayesian experimental design in quantum metrology
Federico Belliardo, Fabio Zoratti, Florian Marquardt +1
Quantum sensors offer control flexibility during estimation by allowing manipulation by the experimenter across various parameters. For each sensing platform, pinpointing the optim…
Heating and cooling processes via phaseonium-driven dynamics of cascade systems
Federico Amato, Claudio Pellitteri, G. Massimo Palma +2
The search for strategies to harness the temperature of quantum systems is one of the main goals in quantum thermodynamics. Here we study the dynamics of a system made of a pair of…
Quantum Sensing of Magnetic Fields with Molecular Spins
Claudio Bonizzoni, Alberto Ghirri, Fabio Santanni +1
Spins are prototypical systems with the potential to probe magnetic fields down to the atomic scale limit. Exploiting their quantum nature through appropriate sensing protocols all…
Critical non-Hermitian topology induced quantum sensing
Saubhik Sarkar, Francesco Ciccarello, Angelo Carollo +1
Non-Hermitian physics predicts open quantum system dynamics with unique topological features such as exceptional points and the non-Hermitian skin effect. We show that this new par…
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…
Design and simulation of a transmon qubit chip for Axion detection
Roberto Moretti, Hervè Atsè Corti, Danilo Labranca +54
Quantum Sensing is a rapidly expanding research field that finds one of its applications in Fundamental Physics, as the search for Dark Matter. Devices based on superconducting qub…
