Quantum entanglement is a property of photons or particles, which travel
at the speed of light for photons or less for particles.

In the case of photons, they are using light (or radio for lower frequencies).
In the case of particles, much much slower.

Hopefully they are not using gamma ray bursts for communication.

Quantum entanglement is not well understood "spooky action at a distance"
has been described as instantaneous "Entanglement, the "spooky" effect in
which far-distant particles appear to influence one another
instantaneously" http://focus.aps.org/story/v10/st29 or ""spooky action at
a distance" -- somehow one particle manages to tell the other
*instantaneously* what its spin was measured to be"
http://www.fnal.gov/pub/inquiring/qu...anglement.html
although others state that no information can be transferred
http://www.wikipedia.org/wiki/Quantum_entanglement. Whether light or other
particles are used and then separated to large distance by conventional
means, the book may not be entirely closed on instantaneous information
transfer.

It's the far out proposition that rather than being emitted with a certain
polarization/spin/whatever, particles don't know their orientation till
someone measures it.

Regardless, even if it's right (and that's an issue all by itself) it's
certain that the carrier of the effect can move no faster than 'c'.

And the problem is, while you can read the state of a particle, you
cannot set it. Even according to the QM types it cannot be used for
superluminal communication.

I've seen no proposals for entanglement that make any sense.

Scientific American had an explanatory cartoon in an issue that
illustrates the issue completely.

A discovery is made on mars. By some unexplained method, it's discoverers
transmit the information with a single qubit. Their compatriots receive
the qubit, make a totally off the wall guess which has nothing to do
with the qubit, make a killing in the stock market and everyone lives
happily ever after.

Don't bet the farm on entanglement, this tree won't bear fruit.

That would be an unproved assumption or speculation.

" ... using gamma ray bursts ..." From the standpoint of the
message recipient, would that be similar to sitting in front
row seats at a heavy metal rock concert; or attending the
"Disaster Area (a plutonium rock band)" concert as described
in Douglas Adams' HHG). g For details, you might review

Besides, even if it could work, the pair of entangled particles
would need to be installed in advance -- which could take 100's
to 1000's of years to accomplish.
