... beam us up Scotty style...
WORKING in Australia have
"beamed up" a radio signal, in the manner of Captain Kirk.
Scientists at the Australian National
University in Canberra say they have been able to teleport a laser beam
The group of researchers led by physicist
Ping Koy Lam have used quantum entanglement - a phenomenon
Ping Koy Lam disassembled laser light at
one end of an optical communications system and recreated a replica
Dr Lam told the BBC: "What we have
demonstrated here is that we can take billions of photons,
He reckons the system could be used to
transport secure data. "It should be possible," he says
While transporting data may be possible, Lam reckons beaming humans to and fro is still some way off.
|What is Teleportation ?
The conveyance of persons
(esp. of oneself) or things by
Probably the best known example is the Star Trek ‘Transporter’.
When it comes to the real thing, teleportation means:
1) Measurement of the input "state", followed by
2) Disembodied transport of the state, and then
3) Perfect reconstruction in every detail.
1) Instantaneous or faster than light
What are the philosophical implications of teleporting?
By definition the reproduction is perfect.
Does this mean there are two brains with the same thoughts?
Should the laws of physics allow this?
Why is teleporting hard?
If you want to teleport an atom, all you need to do is measure the position and the momentum simultaneously.
But, you can not know momentum and position at the same time - IT IS NOT ALLOWED!
This actually solves the brain paradox. If you made
perfect copies of an object (eg. George W.) you could
then measure the position and momentum simultaneously. But this is not allowed.
Quantum mechanics does not let you ‘clone’.
How can it be done (really)?
