Quantum optics is a broad and varied subject that
deals with the study, control, and manipulation of quantum
coherence associated with electromagnetic fields. This includes
nonclassical optical media, the basic interaction of photons and
atoms, and the nonclassical nature of the electromagnetic field
itself. Quantum optics is the natural arena for
experimental tests of the foundations of quantum mechanics and
measurement, especially in the context of open, nonequilibrium
quantum systems. Most recently, developments in theory and
experiment have led to the possibility of applying the coherent
control of quantum optical systems to perform completely new
informationprocessing paradigms such as quantum communication
and quantum computation.
Quantum Optics II (Physics 581)
 Quantum optical particles and waves (discrete and
continuous variables)
 Foundations of entanglement and quantum maps
 Open quantum systems and decoherence
 Quantum trajectories and continuous measurement
 Fundamental paradigms in quantum optics (cavity QED, ion and
neutral atom traps, entangled light)
 Applications in quantum information science (quantum
communication, computation, metrology)
"Recommended" Texts (none required):
* Introduction to Quantum Optics: From the Semiclassical Approach to Quantized Light  Gryberg, Aspect, Fabre
* Quantum Optics  Scully and Zubairy,
* Quantum Optics, by R. Y. Chiao and J. C. Garrision
* Quantum Optics, by M. Fox
We will not be following any of these texts directly . They all have strengths in different areas and are good to have on your bookshelf.
Grading:
* Problem Sets (58 assignments) 75%
* Final Project 25%
* Problem sets will be available on the web, about every other week. Generally assignments will be due Thursdays in TA mailbox.
