| contents | We examine the condition necessary for extracting entanglement from a quantum field through the use of two local modes A and B (detector modes). We show that Simon's entanglement criterion for the bipartite Gaussian state can be reformulated in terms of commutators between the canonical operators of the detector mode B and the partner mode P of the detector mode A. Using the profile representation of detector modes, we identify that harvesting is prohibited under certain specific conditions. According to analyses based on moving mirror models, Hawking radiation originates from the Milne modes at past null infinity, that reflect off at the mirror and ultimately transform into real particle modes. Drawing parallels between the Unruh effect and Hawking radiation, our findings indicate an absence of quantum correlations between ``real particles" emitted as Hawking radiation. |
