A comment on: Adam R. Brown and Leonard Susskind's paper "A holographic wormhole traversed in a quantum computer"

TL;DR

This paper comments on Brown and Susskind's work, highlighting the historical connection between Einstein-Rosen bridges and entanglement, and clarifying Einstein's perspective on their relationship.

Contribution

It provides a historical and conceptual clarification that Einstein viewed ER bridges and EPR entanglement as interconnected, challenging the separation implied in recent holographic discussions.

Findings

Einstein did not see ER bridges and EPR entanglement as separate concepts.

The paper clarifies Einstein's perspective on the relationship between wormholes and entanglement.

It emphasizes the historical context of the ER-EPR connection.

Abstract

Adam Brown and Leonard Susskind write in their new paper, "A holographic wormhole traversed in a quantum computer": "The idea of a wormhole dates back to 1935, when Albert Einstein and his collaborator, Nathan Rosen, studied black holes in the context of Einstein's general theory of relativity. [...] In the same year, Einstein and Rosen wrote another paper, this time in collaboration with Boris Podolsky. [...] At the time, these two ideas - wormholes and entanglement - were considered to be entirely separate". I will show in this comment that for Einstein the Einstein-Rosen (ER) bridge and the EPR argument were not "entirely separate".
