What does this question about entanglement and classical geometry mean?

3939 views

Below is the question from Andy Strominger's presentation at the String 2014 conference. The question was asked by credible physicist Ashoke Sen as an important question.

"What is the precise relation between quantum entanglement and classical geometry?"

Could somebody describe the question and explain why it is an important question and its implications?

I wasn't there but one can guess this is a reference to the "ER=EPR" conjecture.

@SM Kravec. I do not think so. It is from a completely different context than EPR and the like..

These kind of ideas (ER=EPR, etc...), to my knowledge, has begun with this paper of Mark Van Raamsdonk

A link is slightly helpful (but less than I had hoped) for context: http://physics.princeton.edu/strings2014/slides/Strominger.pdf. Question 29. Page 11. Apparently whoever wrote the "Hints" for the many other questions didn't think this needed expansion (or that a hint would have to be too expansive). Page 5 tells us what Strominger asked to evoke his list of 74 questions "that we can concretely address and plausibly hope to answer in the next 5-10 years".

Sorry, this is mistakenly posted as an Answer. I had intended it to be a comment.

@PeterMorgan Ok I have converted it into a comment for now, but I think it's OK as an answer too, though not a direct one...
