Extraction of entanglement from quantum fields with entangled particle detectors

|
By Kensuke Gallock-Yoshimura, Laura Henderson, Robert B. Mann, Dyuman Bhattacharya
| Physical Review B
Abstract We consider two initially entangled Unruh-DeWitt particle detectors and examine how the initial entanglement changes after interacting with a quantum scalar field. Just as initially separable detectors can extract entanglement from the field, entangled detectors also can gain more entanglement so long as they are weakly correlated at the beginning. For initially sufficiently entangled detectors, only degradation takes place.
