Large deviations in quantum dynamics and complexity
Xiangyu Cao, Jorge Kurchan
We study three definitions of large deviation in many-body quantum dynamics: (i) via the full distribution of an extensive observable, (ii) via the distribution of measurement outc…

Redundancy from Subsystem Thermalization
Xiangyu Cao, Zohar Nussinov
In the theory of decoherence, redundancy is the correlation between a quantum system and fractions of the environment. It underlies the emergence of classical behavior. We show tha…

Consistent monitoring of quantum fluctuations
Xiangyu Cao
Recent works on the decoherent histories formalism suggested that slow-evolving macroscopic quantities (extensive sums of local observables) in quantum many-body systems can be con…
