How measuring a quantum field affects entanglement harvesting

We analyzed how entanglement harvesting is affected by the performance of a measurement on quantum field. The field modelled as coupling particle detector to field, followed projective performed detector. In our analysis, we considered different arrangements for two detectors and an ancillary used perform measurement. found regimes performing measurements affects harvested, depending initial final states measure well its strength. identified where it possible during preparation protocols without significantly interfering in harvested. also identify what can degrade or slightly enhance ability harvest entanglement.
