Quote : | "Chinese researchers use quantum physics to "teleport" photons across 10 miles of empty space
China has been taking a beating in the U.S. press lately. the Chinese company Foxxconn has experienced problems with employees committing suicide, the country has not warmed up to U.S. greenhouse gas cut initiatives and has placed a ban on internet maps and satellite imaging. However, the country can be commended for its latest effort -- achieving quantum teleportation.
Scientists at the University of Science and Technology of China and Tsinghua University were able to stream quantum information over 16 km of free space, approximately 10 miles. It's called teleportation, but the matter is not actually moved, instead the quantum state of an object is transferred to another (when something is done to the first object, it immediately happens to the second one).
According to the Shanghaiist website, "It's connecting two photons in a way that when one photon is changed, the other changes simultaneously, allowing for information to be transported between the two without using signals or networks. The protons in this case interacted with '89% fidelity,' meaning that there's a few more tests necessarily before anything can seriously be 'beamed' anywhere."
While we can't "beam" anything up, exactly -- this achievement by China has brought the world the closest that it has ever come to attempting matter teleportation. Because of this advancement we are closing in on the ability to one day send and connect information from long distance without signal interference.
The U.S. and European Union have also conducted teleportation experiments. However, the longest distance they have claimed thus far is quantum teleportation over 600 m, which achieved across the Danube River in 2004. The Chinese claim would be over 25 times as long a teleportation event" |

I love how they make transporter analogies after we move ten photons.
That's like saying that if we can move ten grains of sand we should be able to move the beach pretty soon. 5/28/2010 11:34:29 PM |

eh
moving ten grains of sand probably has more likelihood of being able to move a beach then moving a few photons via quantum entanglement ever will 5/28/2010 11:36:35 PM |

Except that they aren't even moving 10 photons/grains of sand ... it's more like they are pulling strings between grains of sand on different beaches and watching the distant one move when the near one moves. Or something like that.5/28/2010 11:42:28 PM |

I don't know why they even call it teleportation. Quantum entanglement is not teleporting anything but information. 5/29/2010 4:47:22 AM |

Fine, but if that's all you transmit, then at best you're just going to end up making a copy. 5/29/2010 9:00:49 AM |

except it's not "information" in the sense the word "information" is typically used.
The "information" is still random, and will always be random.5/29/2010 12:50:30 PM |

^ For some reason, that post makes me think of "the definition of is is."

I was talking about quantum information which is completely different than "mah fax machine" information
because, you know, quantum theory is the goddamn context of this discussion.5/29/2010 3:44:12 PM |
