Entanglement from Hawking radiation

It is well-known that black holes generate quantum correlations via Hawking’s pair-creation mechanism. In this talk, I’ll adapt tools from Gaussian quantum information theory to quantify the entanglement emission from black holes under different circumstances. These tools offer a remarkably good ratio of power to simplicity and permit us to demonstrate how the creation of entanglement is sensitive to the environment surrounding the horizon. In particular, ambient thermal noise (e.g., the ubiquitous CMB radiation) significantly inhibits the generation of entanglement. Additionally, I will argue that for spinning black holes, the ergoregion encompassing the horizon acts as an independent source of quantum entanglement. I'll conclude by discussing ongoing work towards the experimental verification of these ideas using analog black holes in the laboratory.
