Quantum-driven sampling of the quasi-uniform distribution via quantum walks
Marco Radaelli, Claudia Benedetti, Stefano Olivares
We investigate the use of discrete-time quantum walks to sample from an almost-uniform distribution, in the absence of any external source of randomness. Integers are encoded on th…

Precision bounds for multiple currents in open quantum systems
Saulo V. Moreira, Marco Radaelli, Alessandro Candeloro +2
Thermodynamic (TUR) and kinetic (KUR) uncertainty relations are fundamental bounds constraining the fluctuations of current observables in classical, non-equilibrium systems. Sever…

Parameter estimation for quantum jump unraveling
Marco Radaelli, Joseph A. Smiga, Gabriel T. Landi +1
We consider the estimation of parameters encoded in the measurement record of a continuously monitored quantum system in the jump unraveling, corresponding to a single-shot scenari…
