Learning the noise fingerprint of quantum devices
Noise sources unavoidably affect any quantum technological device. Noise's main features
are expected to strictly depend on the physical platform on which the quantum device is …

Equilibration time in many-body quantum systems
TLM Lezama, EJ Torres-Herrera, F Pérez-Bernal… - Physical Review B, 2021 - APS
Isolated many-body quantum systems quenched far from equilibrium can eventually
equilibrate, but it is not yet clear how long they take to do so. To answer this question, we …

Quantum zeno and anti-zeno probes of noise correlations in photon polarization
We experimentally demonstrate, for the first time, noise diagnostics by repeated quantum
measurements, establishing the ability of a single photon subjected to random polarization …

Quantum Zeno dynamics through stochastic protocols
Quantum measurements play a crucial role in quantum mechanics since they perturb,
unavoidably and irreversibly, the state of the measured quantum system. More extremely …

Tight-binding model subject to conditional resets at random times
We investigate the dynamics of a quantum system subjected to a time-dependent and
conditional resetting protocol. Namely, we ask what happens when the unitary evolution of …

Experimental proof of quantum Zeno-assisted noise sensing
In the ideal quantum Zeno (QZ) effect, repeated quantum projective measurements can
freeze the coherent dynamics of a quantum system. However, in the weak QZ regime …

Quantum random walk and tight-binding model subject to projective measurements at random times
What happens when a quantum system undergoing unitary evolution in time is subject to
repeated projective measurements to the initial state at random times? A question of general …

Nonequilibrium quantum-heat statistics under stochastic projective measurements
In this paper we aim at characterizing the effect of stochastic fluctuations on the distribution
of the energy exchanged by a quantum system with the external environment under …
