Faster than light communication w/ Quantum Entanglement (Bell's telephone)--Possible?
I got intrigued by the following description: of a faster than light communications grid over interstellar distances:
http://www.seti.org.au/spacecom/quantumcom.html
Normally I'd ignore such things on the Internet, but this is hosted on a SETI webserver, an institution with generally respectable scientific credentials.
The short summary is that it's Bell's telephone, but with generator of entangled photons moved to half way between the sender and the receiver. Instead of overlaying another signal on top of the light beam (as in Bell's telephone), the sender uses a shutter to alternate blocking the light (say, a 1 bit) vs. just letting it be (a 0 bit). Observation of the resulting interference pattern at the receiving end should (according to the author) allow the receiver to deduce whether or not the shutter was closed at the other end.
Is this true? Despite being a former engineering physics major, my knowledge of quantum entanglement is too rusty to help me out here..
