Query: Quantum radiation produced by the entanglement of quantum fields   We investigate the quantum radiation produced by an Unruh-De Witt detector in
a uniformly accelerating motion coupled to the vacuum fluctuations. Quantum
radiation is nonvanishing, which is consistent with the previous calculation by
Lin and Hu [Phys. Rev. D 73, 124018 (2006)]. We infer that this quantum
radiation from the Unruh-De Witt detector is generated by the nonlocal
correlation of the Minkowski vacuum state, which has its origin in the
entanglement of the state between the left and the right Rindler wedges.
