In this essay, 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. 
Study on the Relationship between Quantum Entanglement and Spacetime
Quantum entanglement and spacetime are strongly associated fields in modern physics. This paper investigated the connection between quantum entanglement and spacetime, particularly focusing on how
On the nonclassicality in quantum JT gravity
Abstract We consider the question of classicality for the theory that is known to be an effective description of two-dimensional black holes—the Morse quantum mechanics. We calculate the Wigner
Entanglement in Gauge / Gravity Duality by Sunok
In this thesis, we present studies that elucidate the relationship between entanglement in strongly coupled gauge theories and the geometry of their gravity duals. In the first, we find that in a
Geometry of entanglement
The geodesic curvature of a convex curve is proposed as a local measure of factorization of the dual CFT state and its integral will be interpreted as computing the bipartite entanglement among degrees of freedom with support on the chosen domain.

The extent to which a number of related proposals that claim there is a link between spacetime topology and quantum entanglement can be understood as stating a duality is indicated, and two general approaches to articulating such aDuality are considered.
Geometric phases distinguish entangled states in wormhole quantum mechanics
We establish a relation between entanglement in simple quantum mechanical qubit systems and in wormhole physics as considered in the context of the AdS/CFT correspondence. We show that in both cases,
Potential Consequences of Wormhole-Mediated Entanglement
There are hints that the connectivity of space-time in quantum gravity could emerge from entanglement, and it has further been proposed that any two entangled particles may be connected by a quantum

Reconciling quantum mechanics with gravity has long posed a challenge for physicists. Recent developments have seen concepts originally developed in quantum information theory, such as entanglement
