The information paradox and non-locality, ER = EPR

Click For Summary

Discussion Overview

The discussion centers around the black hole information paradox and the concept of non-locality as it relates to the idea of ER = EPR, proposed by Dr. Maldacena and Dr. Susskind. Participants explore the implications of this relationship, particularly in the context of entanglement and wormholes, as well as its theoretical underpinnings and confirmations in various models.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that ER = EPR links entanglement to wormholes, suggesting that the Einstein-Rosen bridge (ER) represents a physical connection between entangled particles (EPR).
  • Others highlight that the concept of non-locality is further elaborated in Maldacena's AdS/CFT correspondence, where 3D space is described as an illusion arising from a 2D boundary.
  • A participant questions the clarity of the initial comment regarding ER = EPR, pointing out that Maldacena and Susskind jointly proposed this idea.
  • Several contributions reference the derivations and confirmations of ER = EPR by Jensen and Karch, and Sonner, discussing how these works support the equivalence of entanglement and wormholes.
  • One participant introduces the term "spinhole" to describe a spatial interconnecting wormhole related to quantum spin, suggesting a model that incorporates the concept of simultaneity in entangled states.
  • Links to external articles are provided, which discuss the implications of microscopic wormholes and their relation to non-locality.

Areas of Agreement / Disagreement

Participants express a range of views on the implications and interpretations of ER = EPR, with no clear consensus reached. Some support the equivalence of entanglement and wormholes, while others raise questions about the clarity and implications of the initial statements.

Contextual Notes

Some discussions reference specific models and theoretical frameworks, such as the holographic duality and the nature of entangled states, which may depend on particular assumptions or definitions that are not fully resolved in the thread.

I heard recently that Dr. Maldecena recently commented to Dr. Susskind, regarding the black hole information paradox, that ER = EPR. Can anyone illuminate this for us mere mortals? It seems to link all information via non-locality, which has interesting implications.

This does not make sense, because Maldacena and Susskind proposed the ER=EPR idea together .

Since I posted this, Scientific American had a very interesting article on microscopic worm holes being the non-locality highway.
 
ER = EPR asserts the equivalence of entanglement to a wormhole, where ER refers to Einstein-Rosen bridge (i.e. a wormhole) and EPR refers to the Einstein-Podolsky-Rosen paradox regarding entanglement.

Maldecena and Susskind first published a derivation in 2013.
General relativity contains solutions in which two distant black holes are connected through the interior via a wormhole, or Einstein-Rosen bridge. These solutions can be interpreted as maximally entangled states of two black holes that form a complex EPR pair. We suggest that similar bridges might be present for more general entangled states.

It was quickly confirmed by Jensen and Karch,
We construct the holographic dual of two colored quasiparticles in maximally supersymmetric Yang-Mills theory entangled in a color singlet Einstein-Podolsky-Rosen (EPR) pair. In the holographic dual, the entanglement is encoded in a geometry of a nontraversable wormhole on the world sheet of the flux tube connecting the pair. This gives a simple example supporting the recent claim by Maldacena and Susskind that EPR pairs and nontraversable wormholes are equivalent descriptions of the same physics.

and by Sonner.
We show that the recently proposed bulk dual of an entangled pair of a quark and an antiquark corresponds to the Lorentzian continuation of the tunneling instanton describing Schwinger pair creation in the dual field theory. This observation supports and further explains the claim by Jensen and Karch that the bulk dual of an Einstein-Podolsky-Rosen pair is a string with a wormhole on its world sheet. We suggest that this constitutes a holographically dual realization of the creation of a Wheeler wormhole.

The first general description however, was given three years prior, right here at PF! “Spinhole” seems apt as quantum spin is the most commonly described entangled property. “Slope zero” applies to the condition where the entangled particles share a simultaneity (i.e. inertial frame).
The 'quantum non-local connection' of the EPR paradox seems to offer us a spinhole (spatial interconnecting wormhole), with slope zero to explain entanglement. So, it's not just outsiders who envision the utility of a "tiny wormholes" model. As I recall, John Wheeler's quantum foam is also filled with them.
