Wikipedia Does it Again.

I read a comment on facebook quoting an article from Wikipedia on superliminal communication in quantum physics. The article is here. My response followed in the comment trail. My points are in red italics.

Wikipedia is not a good source for scientific data even basic mistakes in electronics are visible. Here is part of a discussion from a physics forum on entanglement.

The confusion about "information transfer by entanglement" is probably because there are communications protocols, involving entanglement, but not as an information channel In short, if you have an entangled pair of qbits between users A and B, and also a supplementary communication channel between them (classical), then A and B can communicate securely by a mixture of classical communication and operations/measurements on their qbits. Example: they share a pair of entangled spin-1/2 particles, and A performs an operation on his/her qbit, then sends a message to B with instructions which basis to perform a measurement in, to "read" the message. The actual speed of information transfer is limited by the classical channel; however, an eavesdropper with access only to this and not the entangled qbits, cannot possibly decipher it - hence secure communication! (we hope) This is a frequently-discussed topic (related to quantum teleportation) and may explain the common confusion about this being "information transfer" - which it is not, sticking to standard terminology. Usually we talk about "correlations" between the states of the entangled qbits in different places and times.

I think this is like the argument that superliminal communication is possible as long as no information is transferred. You can't escape relativity any more than you can get "outside" the known universe.
