Harvesting large scale entanglement in de Sitter space with multiple detectors
Shingo Kukita, Yasusada Nambu
We consider entanglement harvesting in de Sitter space using a model of multiple qubit detectors. We obtain the formula of the entanglement negativity for this system. Applying the…

Entanglement dynamics in de Sitter spacetime
Shingo Kukita, Yasusada Nambu
We apply the master equation with dynamical coarse graining approximation to a pair of detectors interacting with a scalar field. By solving the master equation numerically, we inv…
