4 Jan 2023 | 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. | Source: | arXiv, 2301.01566 | Services: | Forum | Review | PDF | Favorites |
