Abstract
Two entangled two-level Unruh-DeWitt detectors, which are in rest, spontaneously lose entanglement when at least one of them is not isolated from the environment quantum fields. For eternal interaction between the detectors and environment, the spontaneous emission from the detectors' exited states and vacuum fluctuations of field influence this negative effect. Consequently, it suggests that two entangled qubits become less communicated during their free fall towards the black hole horizon.
