Quantum Coherence and Information
Seminar Abstracts
This series of talks bearing on issues in quantum measurement theory, foundation and interpretation of quantum mechanics,  quantum decoherence and quantum-classical correspondence, quantum information and computation, is designed to assist graduate students beginning to do research in this newly developing interdisciplinary field.  Its nature will vary from reports of original research to review of recent papers of significance. It is hoped that theoretical discussions of issues and models will draw on current experiments in AMO (atom-field interaction, cavity ions) condensed matter (SQUID, Dots), molecular/nuclear (NMR) and nonlinear sciences (quantum chaos) related to the physics of quantum computer prototypes

Title:      Using Correlation Functions To Measure Entanglement in Quantum Optics
Abstract:

We investigate the evolution of entanglement in a strongly coupled cavity QED optical system when the driving field is weak enough that the steady state value of the intracavity photon number is less than the saturation photon number. We show that cross correlation between the transmitted intensity and the fluorescence of the atoms into modes other than that of the cavity, j(2)(t), is related the the degree of entanglement of the atom(s) and cavity mode.
