- Abstract: Quantum steering is a perplexing feature at the heart of quantum mechanics
that provides profound implications in understanding the nature of physical
reality. On the other hand, the effect of relativistic features on quantum
systems is vital in understanding the underlying foundations of physics. In
this work, we study the effects of Unruh acceleration on the quantum steering
of a two-qubit system. In particular, we consider the so-called quantum
steering ellipsoid and the maximally-steered coherence in a non-inertial frame
and find closed-form analytic expressions for the role of the Unruh
acceleration in these quantities. Analyzing the conditions for the steerability
of the system, we develop a geometric description for the effect of Unruh
acceleration on the quantum steering of a two-qubit system.
