Thank you for your answers! I think the QED is just an application of QFT, in other words, it's an special example, of cause, the application to electronicmagnetism is very successfully. we called it QED. and, the QFT contains the weakforce , strongforce and electromagneism force.

One question has disturbed me long time, I don't know the distinction between quantum electrodynamics and quantum field theory. By the way, which quantum field theory or quantum electrodynamics textbook is prefer?

Yes , the book is very interestring!

Quantum-optics computer is important too?

The Dirac's book has too many mathmatics, and the physical description is profound, If read it, May be I need some basic knowledge of general physics more. by the way, I want to do rearch in superstrings(M-theory), What do I need about quantum mechnics? thank you for JohnDubYa , salsero.

I want ask a question, which textbook of quantum mechanics is appropriate for a beginner? thanks.
