Quantum Correlations and Coherence in a Moving Unruh-deWitt Detector

Published 28 Nov 2022 in quant-ph and gr-qc | (2211.15263v1)

Abstract: In this paper, we investigate the quantum correlations and coherence of two accelerating Unruh-deWitt detectors coupled to a scalar field in 3 + 1 Minkowski space-time. We show that the entanglement is completely destroyed in the limit of infinite acceleration while the local quantum uncertainty and l1-norm of coherence remain nonzero. In addition, we also highlight the role of Unruh temperature and energy spacing of detectors on quantum correlations for different choices of initial states.
