Building up spacetime with quantum entanglement
arXiv:1005.3035 · doi:10.1007/s10714-010-1034-0 10.1142/S0218271810018529
Abstract
In this essay based on 0907.2939, we argue that the emergence of classically connected spacetimes is intimately related to the quantum entanglement of degrees of freedom in a non-perturbative description of quantum gravity. Disentangling the degrees of freedom associated with two regions of spacetime results in these regions pulling apart and pinching off from each other in a way that can be quantified by standard measures of entanglement.
