Human teleportation possible?

    Scientists have reportedly been able to transport atoms and molecules as much as 1800 feet. Could the same be done for humans, or would the Heisenberg Uncertainty Principle ultimately make it impossible?

    I'm quite sure no-one has done any such thing. Do you have a reference? If you are talking about quantum teleportation I hope you realise that the actual physical objects involved don't move anywhere, it is their quantum information which is transferred from one object to another.

    I'm sure it's gonna hurt alot.

    Who ever your source of "information" was, I wouldn't trust them on anything important.

    But sure, we can transport things 1800 feet very easily - and much, much more than that! It's called using guns, vehicles, rockets, etc.

    But teleport ? No way.

    Well would the HUP make a device like, say, a transporter from Star Trek impossible?

    The hypothesis would be that *if* it was possible to teleport matter, that you would require taking a sequence of snapshots of where everything is located at a subatomic level. These snapshots would allow you to create a "Dot to dot" method of trying to "guess" where the subatomic particles are suppose to be.

    The problem as of course you've mentioned with Heisenberg's Uncertainty Principle is that measuring let alone one subatomic particle in this manner, isn't necessarily going to identify the direction the subatomics is going because the apparatus used to take the snapshot utilises and "Active" scan technique. (Basically if you are using photons to identify position, the bombardment of the subatomic particle will send the particle off in a different direction. This causes your dot-to-dot to become chaotic.)

    The only "teleportation" I have heard of was an Australian experiment that "teleported" a photon across a room. (Albeit it's more like a photocopy across the room to my knowledge.)

    This reasoning is why "teleportation" will likely remain something of fiction, and theorists turned to other interpretations like "wormholes".

    So are these limitations fundamental like the speed of light, or can they, at least in principle, be overcome with sufficiently advanced technology?

    Also, in his book 'The Physics of Star Trek', Lawrence Krauss says:

    "The operation of quantum teleportation requires very carefully prepared initial quantum states and then a system that is isolated from its environment throughout the process. Nothing could be further from the situation we exist in, however. We are not quantum objects. If we were, the laws of quantum mechanics would not seem so strange. Macroscopic objects like humans are complex configurations of many particles interacting so frequently with each other and their environment that all quantum mechanical correlations and entanglements are quickly destroyed."

    What exactly does this mean? Is it true?

    that would be like a clone, which doesn't matter since it is identical.

    this makes me think of exact knock offs. if it is identical, how can anyone say one is fake? lol.
