Quantum Teleportation: Is It Possible?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility and implications of quantum teleportation, exploring both theoretical and practical aspects. Participants consider the potential for quantum teleportation to be applied to larger objects, such as humans, and the challenges associated with such endeavors.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants express optimism about the future of quantum teleportation, likening it to technological advancements like fax machines, while others are skeptical about its practicality for macroscopic objects.
  • One participant mentions that quantum teleportation of photons has been successfully demonstrated, but questions remain about the replication process and the implications of destroying the original particle.
  • Concerns are raised regarding decoherence as a significant barrier to teleporting larger sums of atoms, with some participants suggesting that classical teleportation issues still apply alongside quantum challenges.
  • There is a discussion about the potential for quantum teleportation to facilitate real-time communication within the solar system, though some argue that classical communication methods are still necessary for the process to work.
  • Participants debate the nature of teleportation, questioning whether the destruction of the original object is inherent to the concept or if it could be viewed as mere movement without destruction.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of quantum teleportation for larger objects or the implications of the original being destroyed in the process. Multiple competing views and uncertainties remain throughout the discussion.

Contextual Notes

Limitations include unresolved questions about the energy requirements for large-scale teleportation and the dependence on classical communication methods for quantum teleportation to function effectively.

The person we were 1 minute ago, in our physical world as we percieve it, is no longer
the person we are now. (t- n, may never equal t) although I know our set theories tell us that
this should be a part of the set, (if n=0), but we have excluded n=0 many times in the past (boundaries?).

I don't see how this would affect what you are looking for, just might make some old human predjudices obsolete. We have to look at "n" approaching "0" to get as close as we are able.

I agree with Selfadjoint, it is unpalatable, but can not be proven to be incorrect. ( I was about to say is right, but this would not be true.)

It's worth to mention that there are various schemes, various arrangements of entangled particles and procedures to perform the teleportation. Each of these schemes is called a teleportation protocol. The first of these protocols was proposed in 1993 by Bennett, is called Bennett protocol. The protocol known as quantum scissors, was proposed in 1998 by Pegg, Phillips and Barnett. Kak teleportation protocol was proposed in 2003 in this paper

I just notice this thread and will have a go through. I would not like disseminate what has already been hashed out logically and consistently.

I think this well sets the definitions for the Philosophy of Teleportation Thread.

Can these threads be joined under this heading?
