BUILDING UP SPACE–TIME WITH QUANTUM ENTANGLEMENT

Abstract

In this essay, we argue that the emergence of classically connected space–times is intimately related to the quantum entanglement of degrees of freedom in a nonperturbative description of quantum gravity. Disentangling the degrees of freedom associated with two regions of space–time results in these regions pulling apart and pinching off from each other in a way that can be quantified by standard measures of entanglement.
