• Title: Genuine tripartite entanglement of W state subject to Hawking effect of a Schwarzschild black hole
• Authors: Shu-Min Wu, Xiao-Wei Fan, Xiao-Li Huang, Hao-Sheng Zeng
• Abstract summary: We study the genuine tripartite entanglement (GTE), one-tangle and two-tangle of W state of fermionic fields in the background of a Schwarzschild black hole. We find that, with the increase of the Hawking temperature, the GTE of W state first decreases and then tends to zero, while the GTE of GHZ state first decreases and then freezes.

• Abstract: We study the genuine tripartite entanglement (GTE), one-tangle and two-tangle of W state of fermionic fields in the background of a Schwarzschild black hole. We find that, with the increase of the Hawking temperature, the GTE of W state first decreases and then tends to zero, while the GTE of GHZ state first decreases and then freezes. We also find that the Hawking effect can completely destroy the two-tangle of W state, whilie one-tangle first decreases and then appears freezing phenomenon with the growth of the Hawking temperature. These results are helpful to guide us to select appropriate quantum states and quantum resources to deal with relativistic quantum information tasks.

The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
