Click For Summary

Discussion Overview

The discussion revolves around the potential for macro quantum entanglement to enable teleportation, particularly focusing on the theoretical implications and challenges of entangling all particles in a human body with particles at a destination. Participants explore various hypotheses and models related to quantum teleportation and the feasibility of such processes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant hypothesizes that if every particle of a human body could be entangled with particles at a destination, teleportation might be possible by sending the body's quantum information through entanglement.
  • Another participant questions whether this would require making a complete copy of the particles at the original location first.
  • A different viewpoint suggests that wormholes in General Relativity could provide a means to teleport macroscopic objects, proposing that understanding quantum gravity might allow for practical teleportation without requiring vast energy resources.
  • Some participants acknowledge that while quantum entanglement theoretically enables teleportation, achieving entanglement of an entire person is likely incredibly difficult or impossible due to issues like decoherence.
  • There is mention of the "no cloning" rule in quantum mechanics, indicating that some classical information must still be transmitted, which complicates the teleportation process.
  • A participant references an article by Anton Zeilinger that discusses the theoretical possibility of quantum teleportation for macro objects, noting that while it is conceptually interesting, practical implementation faces significant challenges.

Areas of Agreement / Disagreement

Participants express a mix of agreement and disagreement regarding the feasibility of macro quantum teleportation. While some believe it is theoretically possible, others emphasize the practical impossibilities and challenges, particularly concerning decoherence and the requirements of classical information transmission.

Contextual Notes

Participants highlight limitations related to decoherence, the need for classical information, and the practical challenges of entangling all particles in a human body. These factors contribute to the ongoing uncertainty surrounding the feasibility of teleportation through quantum entanglement.

Can macro quantum entanglement make teleportation possible?? i had a

Can macro quantum entanglement make teleportation possible?? i had a kind of hypothesis...that if we entangle each and every particle of a human body with other particles which are at the destination then can't we make the person teleport at the destination by sending his body's quantum information there through entanglement??
 
Physics news on Phys.org
But doesn't that require making a complete copy of the particles here first? :confused:

Wormholes in General Relativity may be the best way to teleport macroscopic objects. Once we understand quantum gravity. It won't require the energy of an entire solar system to build wormhole between say US and UK, but merely by reprogramming the differential manifold and adjustment of the Einstein Field Equation. Another is to quantum tunnel spacetime points itself. That way, (perhaps) the entire particles can be transported, not just transfer the quantum state but the particle itself.
 


quantum entanglement does make teleportation possible.
unfortunately, quantum entanglement of an entire person would be incredibly difficult, maybe impossible (due to decoherence). It's an interesting question though.
 


Entanglement enables the copying of the quantum states of a particle in spite of the "no cloning" rule. Some information must be transmitted classically however so there in no "get out of jail free" card from Relativity.

i am aware about decoherence...but if somehow we can overcome it...(i mean theoretically)...wont that make teleportation possible then through quantum entanglement...i think its an interesting field to do research...
 


There was some discussion of how it would in principle be possible to quantum teleport macro objects (though probably impossible in practice) on this thread, and I linked to a Scientific American article by a quantum physicist which has some illustrations of how it would work:

See for example the Scientific American article by Anton Zeilinger (a physicist known for his work in quantum teleportation, among other subjects) which starts on p. 9 http://www.scribd.com/doc/47422884/Extreme-Physics-Scientific-American-February-2004 , the illustrations at the bottom of pp. 10-13 show conceptually how quantum teleportation would work for a macro object like a person (they note this is "impossible in practice but a good example to aid the imagination"), and the "Skeptic's Corner" sidebar on p. 15 where "the author answers common teleportation questions" seems to say that the problems with teleportation of macro objects are practical ones like preventing decoherence and storing the vast amount of classical information that would be needed, but doesn't suggest any fundamental theoretical problems with the idea

pretty good article. I guess it might be possible in theory, but practically impossible at the moment.
