Grad studies in quantum information/computing

Any suggestions as to which grad schools are active in the field of
quantum information/computation? Preferably in North America but
possibly also in Europe/Australia...

I am asking in view of applying for a Ph.D. in Quantum Information
(not cryptography, though, but more things like teleportation,
entanglement etc). If anybody been there done that, please share your
experience and if you think this field of research is promising enough
to go down the long and dirty road of grad studies. (Whatever
"promising" means...)
