Over at Dot Physics, Rhett is taking another whack at photons.
A reader emailed me with a few questions regarding How to Teach Physics to Your Dog, one of which is too good not to turn into a blog post:
Part two of three of an explanation of "quantum teleportation" experiments, from July of 2002. This one goes through the basics how teleportation works.

I had long suspected it was possible to create photons with different sorts of waveforms (certainly, the coherence length could be adjusted by means of the formation interval.) However, unimaginative textbooks often said or implied, that a photons is fully characterized by its polarization state and energy,momentum. I don't know why I didn't hear more about the prospects and theory of photon wave-shaping before.
