Bayesian Monitoring of a Diffusive Particle in One Dimension
Federico Gerbino, Guido Giachetti, Pierre Le Doussal +1
We study the Bayesian monitoring of a single particle diffusing along a line, while an observer tracks it continuously using noisy measurements at each spatial point. The average S…
Universal purification dynamics of monitored Clifford circuits
Beatrice Magni, Federico Gerbino, Xhek Turkeshi +1
Quantum circuits under sufficiently weak monitoring purify on a timescale exponentially long in the system size. This slowness underlies a universal purification dynamics, wh…
Universal purification dynamics in real non-unitary quantum processes
Federico Gerbino, Donghoon Kim, Guido Giachetti +2
We study purification dynamics in monitored quantum processes governed by ensembles of quantum circuits in different random-matrix symmetry classes. We analyze the universal aspect…
Measurement-Induced Phase Transition in State Estimation of Chaotic Systems and the Directed Polymer
Federico Gerbino, Guido Giachetti, Pierre Le Doussal +1
We introduce a solvable model of a measurement-induced phase transition (MIPT) in a deterministic but chaotic dynamical system with a positive Lyapunov exponent. In this setup, an…
Kinetics of Quantum Reaction-Diffusion systems
Federico Gerbino, Igor Lesanovsky, Gabriele Perfetto
We discuss many-body fermionic and bosonic systems subject to dissipative particle losses in arbitrary spatial dimensions , within the Keldysh path-integral formulation of the q…
A Dyson Brownian motion model for weak measurements in chaotic quantum systems
Federico Gerbino, Pierre Le Doussal, Guido Giachetti +1
We consider a toy model for the study of monitored dynamics in a many-body quantum systems. We study the stochastic Schrodinger equation resulting from the continuous monitoring wi…
Large-scale universality in quantum reaction-diffusion from Keldysh field theory
Federico Gerbino, Igor Lesanovsky, Gabriele Perfetto
We consider the quantum reaction-diffusion dynamics in spatial dimensions of a Fermi gas subject to binary annihilation reactions . These systems display col…
