What is Teleportation: Definition and 115 Discussions

Teleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction literature, film, video games, and television. Teleportation is often paired with time travel, being that the travelling between the two points takes an unknown period of time, sometimes being immediate.
Teleportation has not yet been implemented in the real world. There is no known physical mechanism that would allow this. Frequently appearing scientific papers and media articles with the term teleportation typically report on so-called "quantum teleportation", a scheme for information transfer.

    Other means of quantum teleportation.

    I've be looking up research on Quantum Teleportation and after reading a discussion about it, it had me wondering. If it might be impossible, in some eyes, to have the information scanned from a human being and then send it to the desired location, would it be possible instead to step away from...

    Question about the Unitary Operation in Teleportation

    Question about the "Unitary Operation" in Teleportation How is the unitary operation actually performed in quantum teleportation(by Bob)? I can never seem to find a thorough explanation of this when I look up teleportation in the literature or on the internet. I understand that Bob's particle...

    Quantum teleportation of macroscopic objects

    I've started a couple of threads about this topic before, but those were a while ago, and I still have some nagging questions. 1.) If we wanted to quantum teleport something macroscopic, would scanning come into play? I thought that the whole point of QT was that you don't have to scan...

    A few more questions about quantum teleportation

    Could quantum teleportation be used to teleport humans?
