Disproofs of Bell, GHZ, and Hardy Type Theorems and the Illusion of Entanglement

Click For Summary

Discussion Overview

The discussion revolves around the claims made in Joy Christian's paper 'Disproofs of Bell, GHZ, and Hardy Type Theorems and the Illusion of Entanglement', which asserts a topological error in Bell's representation and proposes a local-realistic framework for understanding quantum entanglement. Participants explore the implications of these claims, the validity of the paper, and the broader context of testing quantum entanglement.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the validity of Christian's claims, noting that Bell-type experiments are just one method to test quantum entanglement and suggesting that other methods, such as those mentioned in Nature, should also be considered.
  • Others question the appropriateness of discussing the paper in the current forum, emphasizing the need for peer review before engaging deeply with its claims.
  • One participant recalls that Christian's work has been previously discussed and that rebuttals exist, but questions whether any of his claims have been published in a reputable journal.
  • There is a mention of initial impressions of the paper as potentially 'crackpot', but this is tempered by an acknowledgment of the participant's lack of expertise in the area.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of Christian's claims or the appropriateness of the discussion in the current forum. Multiple competing views remain regarding the significance of the paper and the methods of testing quantum entanglement.

Contextual Notes

Participants note the absence of peer-reviewed validation for Christian's claims and express uncertainty about the implications of the proposed local-realistic framework. There is also a recognition of the need for further exploration of alternative methods to test quantum entanglement beyond those discussed in the paper.

Hey guys, hope your all well. Was wondering what people make of the claims made in the paper 'Disproofs of Bell, GHZ, and Hardy Type Theorems and the Illusion of Entanglement' by Joy Christian ( http://arxiv.org/abs/0904.4259 ) where he claims ''An elementary topological error in Bell's representation of the EPR elements of reality is identified. Once recognized, it leads to a topologically correct local-realistic framework that provides exact, deterministic, and local underpinning of at least the Bell, GHZ-3, GHZ-4, and Hardy states. The correlations exhibited by these states are shown to be exactly the classical correlations among the points of a 3 or 7-sphere, both of which are closed under multiplication, and hence preserve the locality condition of Bell. The alleged non-localities of these states are thus shown to result from misidentified topologies of the EPR elements of reality. When topologies are correctly identified, local-realistic completion of any arbitrary entangled state is always guaranteed in our framework. This vindicates EPR, and entails that quantum entanglement is best understood as an illusion.''

I'd be fascinated to hear your thoughts and opinions on this. Cheers guys and stay safe : )

Er... Bell-type experiments are only ONE way to test quantum entanglement. Another one would be going beyond the diffraction limit.

Nature v.429 p.161 and p.158.

How come that wasn't mentioned?

This is not BTSM topic. It is QM. And in this case, we need to wait until this is published first before we spend time on it. If it doesn't get published, then how are we to know that we haven't wasted our time on something that isn't even considered to be valid by those in the community?

My mistake for posting in the wrong area, appologies. When i first saw it i thought 'crackpot' but I am no expert in this area and was curious as to the veracity of its claims.

Christian's work has been discussed here before, from which I gather that several rebuttals have been posted on arXiv, along with a rejoinder from Christian. But has he gotten anything through peer review and published in a "real journal" yet?
