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 e?ects such as wave packet revivals, squeezing and entanglement solely from tomograms circumvent detailed state reconstruction. Several bipartite entanglement indicators are de?ned based on tomograms, and their e?cacy assessed in models of atom-?eld 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 di?erent time scales. The book is aimed at researchers in the areas of quantum optics and quantum dynamics.
