I'm also told he followed that with "And anyone who does > understand quantum physics is insane."(Or some such statement.) That's not so true now. We've had 80 years to think about it. While I'm no expert, I've been thinking about the ramafications of QM for a few years now....more than I care to admit. :-) It is valid statement if one equates "understands" with "provides a realistic explaination of." If one does not require a realistic philosophy, then understanding comes a lot easier. I tend to like a Kantiant philsophy as a foundation. > Here's the article from Physics Web: > http://www.physicsweb.org/article/news/8/6/10 > Thanks. That does explain it accurately, if not fully. I don't fault the lack of a full explaination, but it means that the article is open to misinterpretation from those who do not understand QM. > > The basic problem here is that what quantum physicists are calling > teleportation isn't really the same thing that Star Trek calls teleportation.

One good rule of thumb to use is that it is impossible to transfer information from A to B. The reason for this is, for spacelike events A & B, there are an infinity of reference frames in which A is before B and an infinity for which B is before A. Thus, while it is acceptable to know at B what the state is at A, it has to be in a manner that makes as much sense to say B is after A and A is after B. Lets say, for example, the 3004 Master's golf tournament is played, and our brave colonists at a star system 30 light years away are avid golfers. Given the present laws of physics, there is no way to have quantum entanglement allow them to know the results before 3034. If we could send a person from earth to that colony, or make a copy of a person at the colony, we could do it right after someone watches the 3004 Masters and then copy that person so he could tell the avid golfers who won. We could then copy them send someone back to earth in 2990 and have them place a bet on that golfer. :-) BTW, I don't recognize you as a regular poster. If you are new, welcome.
