Discussion Overview

The discussion centers on the nature of entanglement in quantum mechanics and whether it implies faster-than-light information transfer. Participants explore theoretical implications, analogies, and interpretations related to entangled particles and their behavior across distances.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if entangled particles operate under principles that allow for faster-than-light information transfer, suggesting that changes to one particle occur instantaneously in the other.
  • Another participant argues that the information is not traveling but exists simultaneously at both locations due to a connection via a non-physical continuum, although they acknowledge this may be an inaccurate description.
  • A participant challenges the term "information transpiration," seeking clarification on its meaning.
  • Several participants reference an analogy involving coins to illustrate entanglement, suggesting that knowing the state of one coin instantly reveals the state of another, though they note that this does not imply actual information travel.
  • Some participants mention proofs by Bell and others that suggest entanglement cannot be explained as instantaneous information transfer, while others assert that the analogy remains a useful conceptual tool without violating Special Relativity.
  • There is a discussion about the definition of information, with one participant arguing that for information to be considered as having traveled, it must be knowledge not previously available to the recipient.

Areas of Agreement / Disagreement

Participants express differing views on whether entanglement implies faster-than-light information transfer. While some find the analogy useful, others emphasize the limitations of such interpretations and reference established proofs that challenge the notion of instantaneous information transfer.

Contextual Notes

Participants highlight the complexity of defining information in the context of entanglement and the implications of Special Relativity. There are unresolved assumptions regarding the nature of the connection between entangled particles and the interpretation of their behavior.

Forgive me for such a basic question, but recently I have been reading up on entangled particles. It seems that a lot of that information would lead one to believe that entangled particles don't operate on the principle that light is the fastest means of information transpiration. If what happens to one entangled particle instantaneously occurs to the other, wouldn't that pave the way for information travel that moved faster than light?
 
Physics news on Phys.org
The thing is when that happens to particles, the information is not traveling, it is simply at both places at once. The information being the way the particle is set up/existing. It has to do with the Time-Space continuum on the other side of the " universal spectrum" that isn't actually occupied by physical constructs. Potential Physical space/entities just exists as part of the fundamental nature of the Space-Time Continuum which we live in. Er a better way of putting it is that in Time-Space there is no such thing as physical location but the 2 entangled particles have a connection via Time-Space. Meaning the information of the particle isn't traveling at all, it simply is in both places because there is a connection via a non-physical continuum. Which may be an inaccurate way of describing it.
 
Information transpiration?
 
Prof. Susskind gives a really good comparison of entanglement with the situation where someone has a penny and a dime.
Without looking which is which, you give one to a friend, who takes it to Alpha Proxima (or wherever).
Then you look at the coin in your hand. If it's a penny, you know instantly that the other coin at Alpha Proxima is a dime - and vice versa.
Spooky eh?
The information about the dime has traveled all the way from AP instantly.

There are proofs (Bell and others) that entanglement CANNOT be explained in that way.

Nobody said otherwise. In the context it's an adequate explanation of information transfer without violation of Special Relativity.
If you don't agree take it up with LS. I'm just quoting.

Of course, the information has not really traveled instantly. In fact, it has not traveled at all. In order for one to say that any information has traveled at all, much less instantly, one would have to define information as that knowledge or data which would otherwise not be available to the recipient. In the case of the coin, the information is already available to the holder of the coin, and it is only because the holder has not yet chosen to avail himself of the information that he does not yet "know" which coin he holds.

Nevertheless, it is an interesting analogy to the original concept.
