Here's a brief excerpt:
-----------------
PopSci: Let's talk about some concepts that are familiar in the show and that you talk about in your book, like teleportation. There is a scene in the movie where Kirk and Sulu are falling without a parachute, and they have to be beamed up; Chekov decides he has to do it manually. Unlike "The Next Generation," which had "Heisenberg compensators," the movie doesn't mention the Heisenberg uncertainty principle (the more precisely you locate the position of a particle, the less you can know about its momentum.) I know there has been success in teleporting atoms, but will we ever be able to teleport a human?
Michio Kaku: Well, quantum teleportation already exists. For the past 10 years, we've been teleporting photons as well as atoms of cesium and rubidium and terbium. The world record is 1,800 feet, across the Danube River. I suspect very soon that we will be teleporting molecules. I wouldn't be surprised if, in the coming decades, we are able to teleport DNA, or maybe even a virus. But beyond that, it starts to get very difficult. You have to entangle two atoms, they have to vibrate in unison, and that is very difficult beyond the molecular level. But, Star Trek takes place in the 23rd century, so maybe by then we can teleport 100 trillion cells, which is about the number of cells in a human body.

For those who don't know who Michio Kaku is, he is a super awesome dude who built an atom-smasher in his garage when he was 14 years old (no lie). It was his science fair project. He also faught in Nam!
I highly recommend his books: Visions, Hyperspace and Parallel Worlds. He has lots of other books that I haven't read, so I can't comment on them, but the three above-mentioned are super easy to read and very well-written. Go to mkaku.org and learn all about Dr. Kaku!!!
As mentioned previously, he is super awesome.
