I don't think we're even playing the same sport here
No i don't this we are playing the same sport.
im playing contact sport & your playing tiddly winks.
The information they sent, is the same information the original team, the Australian team sent over ten years ago. ..... catch up son.

Australian teleport breakthrough
By Dr David Whitehouse
BBC News Online science editor
It is a long way from Star Trek, but teleportation - the disembodiment of an object in one location and its reconstruction in another - has been successfully carried out in a physics lab in Australia.
Scientists at the Australian National University (ANU) made a beam of light disappear in one place and reappear in another a short distance away.
The achievement confirms that in theory teleportation is possible, at least for sub-atomic particles; whether it can be done for larger systems, such as atoms, remains to be seen.
The more likely applications will come in telecommunications, enabling much faster transfer of data and the use of encryption that can never be broken.
Will we ever be able to teleport humans?
Teleportation has been one of the hottest topics among physicists working in quantum mechanics - the study of the fundamental structure of matter.
The Australian researchers have exploited a phenomenon called "quantum entanglement", which links the properties of two photons of light created at the same time. Einstein called it a "spooky interaction".
What it means is that two photons can be created and sent to different places. It is possible to force one photon into a specific quantum mechanical state and, because the two photons are connected in some way, the other photon will instantaneously take up a complementary state.
At first sight, entanglement offers the prospect of sending a signal faster than the speed of light. But a closer look at what is actually possible shows that this will not work because of the limits of what can be known about quantum mechanical systems and how such information is relayed.
But it may offer the prospect of a Star Trek-style transporter.
Using quantum entanglement, ANU physicist Ping Koy Lam has disassembled laser light at one end of an optical communications system and recreated a replica just a metre away.
An encoded signal is embedded in an input stream of photons, which is entangled with another beam.
Elsewhere in the lab, the beam of photons and the associated signal is reconstituted.
"What we have demonstrated here is that we can take billions of photons, destroy them simultaneously, and then recreate them in another place," Dr Lam says.
"The applications of teleportation for computers and communications over the next decade are very exciting," he adds.
Quantum teleportation could make encrypted or coded information 100% secure, Dr Lam said, because even if intercepted the message would be unintelligible unless it was intended for a specific recipient.
Quantum teleporting is problematic for humans because the original is destroyed in the process of creating the replica.
Quantum Teleportation Sends Information 143 Kilometers

SchrodingerZ writes "Scientists from around the world have collaborated to achieve quantum teleportation over 143 kilometers in free space. Quantum information was sent between the Canary Islands of La Palma and Tenerife. Quantum teleportation is not how it is made out in Star Trek, though. Instead of sending an object (in this case a photon) from one location to another; the information of its quantum state is sent, making a photon on the other end look identical to the original. 'Teleportation across 143 kilometres is a crucial milestone in this research, since that is roughly the minimum distance between the ground and orbiting satellites.' It is the hope of the research team that this experiment will lead to commercial use of quantum teleportation to interact with satellites and ground stations. This will increase the efficiency of satellite communication and help with the expansion of quantum internet usage. The full paper on the experiment can be found [note: abstract only, full article paywalled] in the journal Nature."
It's the god dam iformation that forms the beam of light that both teams have sent.
They sent the information that makes the beam of light from one place to another, thus ......
They recreated the light in another location by sending it's quantum makeup ( the information ).
were playing a different sport alright son.
