Query: Entanglement and discord: accelerated observations of local and global
  modes   We investigate the amount of entanglement and quantum discord extractable
from a two mode squeezed state as considered from the viewpoint of two
observers, Alice (inertial) and Rob (accelerated). We find that using localized
modes produces qualitatively different correlation properties for large
accelerations than do Unruh modes. Specifically, the entanglement undergoes a
sudden death as a function of acceleration and the discord asymptotes to zero
in the limit of infinite acceleration. We conclude that the previous Unruh mode
analyses do not determine the acceleration dependent entanglement and discord
degradation of a given quantum state.
