Nonclassical Effects and Dynamics of Quantum Observables

This book explores interesting possibilities of extracting information about quantum states

from data readily obtained from experiments, such as tomograms and expectation values of

appropriate observables. The procedures suggested for identifying nonclassical effects such

as wave packet revivals, squeezing and entanglement solely from tomograms circumvent

detailed state reconstruction. Several bipartite entanglement indicators are defined based

on tomograms, and their efficacy assessed in models of atom-field interactions and qubit

systems. Tools of classical ergodic theory such as time series and network analysis are

applied to quantum observables treated as dynamical variables. This brings out novel

aspects involving different time scales. The book is aimed at researchers in the areas of

quantum optics and quantum dynamics.
