The Takeaway

This research shows that the radiation coming from a black hole creates a specific type of entanglement that fills volume rather than just a surface. Remarkably, we can now test this 'impossible' physics using simulations and cold-atom experiments right here on Earth.

From the abstract

The quantum information content of Hawking radiation holds the key to understanding black-hole evaporation and the fate of unitarity. Motivated by recent advances in cold-atom experiments, we develop a lattice-regularization approach aimed at simulating the coarse-grained entanglement scaling of a quantum field in a 1+1D analogue black-hole background. We provide the first concrete demonstration that logarithmic negativity -- an entanglement monotone that typically exhibits a UV-divergent log-sc
