Quantum steering between two accelerated parties

Abstract

We study the Gaussian steering between Unruh modes in the two-mode squeezed states shared by two accelerated observers. We find that the steerability degrades with the increasing of the accelerations of the two observers. An interesting discovery is that the observer who has larger acceleration has stronger steerability than the other one. The condition for the occurrence of maximal steering asymmetry and the parameter regions for two-way, one-way and no-way steering are presented.
