摘要：We show that for a pair of rotating atoms under pure vacuum noise with appropriate orbital radius and angular velocity, nonlocal entanglement as compared to local coherence is not only more resilient against vacuum noise to be preserved in the steady-state for initially entangled states, but more importantly is also predestined to be created and be preserved for initially separable states. The asymptotic entanglement as a result of centripetal acceleration is thus initial-state independent and can be viewed as a manifestation of the Unruh effect. Based on this phenomenon, we propose an optomechanical setup to detect the Unruh effect with the state-of-the-art technologies。
