- Abstract
Based on the model of Unruh–Dewitt detector coupled to a massless scalar field, we investigate the nonlocal advantage of quantum coherence (NAQC) and Bell nonlocality (BN) under Unruh effect, where one of the observers is uniformly accelerated. It is shown that the thermal noise induced by Unruh radiation really destroys quantum resource such as NAQC and BN, and narrows both the region of mixing parameter for Werner state capturing NAQC and BN. From the view of hierarchical relations, quantum correlation responsible for NAQC is stronger than BN in relativistic setting, which means NAQC can be expected to be a useful physical resource for quantum information processing in the regime of relativistic motion.
