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.
