Hmm .. thanks Rob and Steven;

It seems one needs to be careful about what one reads on this subject.

Wiki's opening paragraph on entanglement is kind of where I was coming from in my last post to Steven, (although, I have read this interpretation elsewhere):

Quote:
Quantum entanglement, also called the quantum non-local connection, is a property of certain states of a quantum system containing two or more distinct objects, in which the information describing the objects is inextricably linked such that performing a measurement on one immediately alters properties of the other, even when separated at arbitrary distances.
However, further down it says:

Quote:
When each of the particles in the entangled pair is measured in the same way, the results of their spin measurement will be correlated. Measuring one member of the pair tells you what the spin of the other member is without actually measuring its spin.
There's a big difference between saying one's spin is correlated with the other, and saying that the measurement itself alters the other's spin.

So which one should I believe ?

Cheers
