Ivan Tuzikov Posted October 16, 2012 Posted October 16, 2012 Hi everybody. My question is strictly theoretical and consists of two subquestions: 1. Is it possible (in theory) to teleport an object (for example a coin) to some point in space where already exists another object (for example a log) and integrate it in it? 2. Is it possible to make it without making any sounds in the destination point in space?
swansont Posted October 16, 2012 Posted October 16, 2012 I don't think there's any viable theory that predicts that this could happen.
FrostySnow Posted October 16, 2012 Posted October 16, 2012 Quantum entanglement is as close as it gets for not at least. I recently read an article that the chinese research has done this over 125 miles apart.. http://www.zdnet.com/quantum-teleportation-over-143km-smashes-distance-record-7000003883/ definitely maybe!

Still I can't trace back and believe this has noting to do with the subject(

Ronald Hyde Posted October 16, 2012 Posted October 16, 2012 With teleportation you have a problem with the local nature of the conservation laws. Special Relativity requires that if some quantity is conserved it has to be locally conserved, that is it has to go through space to get from one point to another, it can't just jump from one place to another. 1
EquisDeXD Posted October 17, 2012 Posted October 17, 2012 It doesn't. Quantum teleportation is about sending information, not matter. Technically, isn't matter teleporting all the time, based on our measurements? We measure a particle, and then all of a sudden we measure a particle at another point without seeing it pass through the intervening space, and then particles instantaneously change quantum states as well...
pcalton Posted October 17, 2012 Posted October 17, 2012 It doesn't. Quantum teleportation is about sending information, not matter. Please clarify "information." It not being matter. Does information involve waves or vibrations? It doesn't. Quantum teleportation is about sending information, not matter. Please clarify "information." It not being matter. Does information involve waves or vibrations?
swansont Posted October 17, 2012 Posted October 17, 2012 Please clarify "information." It not being matter. Does information involve waves or vibrations? The quantum state of a particle is what was "teleported" in these experiments. The key to is not that the information was sent, but that if you simply did this classically, you would get it wrong half the time (or 2/3 of the time for some measurements) and the QM techniques did much better than that. Technically, isn't matter teleporting all the time, based on our measurements? We measure a particle, and then all of a sudden we measure a particle at another point without seeing it pass through the intervening space, and then particles instantaneously change quantum states as well... We call that tunneling rather than teleportation.

A most clear answer as yet, thank you!
EquisDeXD Posted October 17, 2012 Posted October 17, 2012 We call that tunneling rather than teleportation. But isn't that essentially what teleportation is?
Pugdaddy Posted October 18, 2012 Posted October 18, 2012 I was thinking that the whole reason teleportation would be desirable is to go from one place to another instantly. It doesn't really matter if you go through space or not. I know the Alcubuerra metric was thought of as a way to shorten intersteller travel times. I was wondering if that the Alcubuerra Metric describing the expansion of spacetime in front and contraction of spacetime behind could be adapted for short distances. If we could do that, would that not be better than teleportation? In theory you could travel to anyplace on earth instantly.
swansont Posted October 18, 2012 Posted October 18, 2012 But isn't that essentially what teleportation is? I think teleportation implies a controlled transport to a chosen destination at an arbitrary distance. Tunneling is much more localized and probabilistic.
