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 information-processing 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 Semi-classical 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 (5-8 assignments) 75%
* Final Project 25%
* Problem sets will be available on the web, about every other week. Generally assignments will be due in class, Wednesdays.
