报告主题：Vacuum Entanglement in QFT: From Theory to Experiments
报告摘要：Although it is know that the vacuum of a massless scalar field contains entanglement between any pair of disjoint spacetime regions, this entanglement has not yet been quantified or experimentally measured. In this talk I will discuss recent progress on 1) the theoretical quantification of vacuum entanglement through local modes in QFT, 2) optimizations of the operational approach to vacuum entanglement extraction through the protocol of entanglement harvesting, and 3) a recent experimental proposal of entanglement harvesting, extracting entanglement from the ground state of a Bose-Einstein condensate using localized polarons that couple to it in effectively causally disconnected regions.
