FTL communication using quantum tunneling has arrived? |
Here is the link to the German article:
http://www.heise.de/newsticker/meldung/64004
It mentions this English paper:
http://arxiv.org/PS_cache/physics/pdf/0103/0103073.pdf
I have not read all of the paper yet, but in Germany
they have a demo setup for the public that uses perspex sheets
and an alu reflector.
It seems serious, but reflection.......
OK
Now start bashing it?

They are serious. I have been following this work for some time. Of all the
various schemes brought to bear on the problem of superluminal
communications, this is one that has the best probability of success. But,
bear in mind it is not going to set the world on fire... photonic barrier
penetration using materials with negative refractive indexes is an old trick
known for ages. How much 'time' will tunneling photons be able to cut off
their total propagation lengths? A few microseconds? Hah. This is perhaps
only a beginning designed as a proof of principle. There is *much* more to
effective quantum information transfer than simple photon tunneling would
allow. Again,a critical limitation of the tunneling setup is going to be
noise. This is a big problem which will continuously cause the tunneling
pipeline to degenerate over any realistic distance. This is not a problem
these present researchers will be able to surmount with their present design
methodologies. Believe me, measuring time gains on the order of quantum
wavelengths will not create a useful communication modality based on
evanescent waves. But a demonstration device would perhaps be useful in
gaining funding for the several decades they must go before these guys can
even catch up to where I presently am. Good luck, and hope they don't kill
themselves...

**************
So the solution is simple. Just build cables of this material out to
the Clarke orbit, and then to Alpha Centauri, and then to all the other
stars...- no problemo.

The wait time for normal tunnelling means STL.
