Extraction of entanglement from quantum fields with entangled particle detectors
Dyuman Bhattacharya, Kensuke Gallock-Yoshimura, Laura J. Henderson +1
We consider two initially entangled Unruh-DeWitt particle detectors and examine how the initial entanglement changes after interacting with a quantum scalar field. As initially non…
Mutual information harvested by uniformly accelerated particle detectors
Manar Naeem, Kensuke Gallock-Yoshimura, Robert B. Mann
We investigate the mutual information harvesting protocol for two uniformly accelerated particle detectors. We numerically show that, while a single detector responds as if it is i…
Entanglement harvesting of three Unruh-DeWitt detectors
Diana Mendez-Avalos, Laura J. Henderson, Kensuke Gallock-Yoshimura +1
We analyze a tripartite entanglement harvesting protocol with three Unruh-DeWitt detectors adiabatically interacting with a quantum scalar field. We consider linear, equilateral tr…
Stellar representation of extremal Wigner-negative spin states
Jack Davis, Robie Hennigar, Robert B. Mann +1
The Majorana stellar representation is used to characterize spin states that have a maximally negative Wigner quasiprobability distribution on a spherical phase space. These maxima…
Entanglement Harvesting of Inertially Moving Unruh-DeWitt Detectors in Minkowski Spacetime
Cendikiawan Suryaatmadja, Wan Cong, Robert . B. Mann
We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent and constant velocitie…
Harvesting mutual information from BTZ black hole spacetime
Kendra Bueley, Luosi Huang, Kensuke Gallock-Yoshimura +1
We investigate the correlation harvesting protocol for mutual information between two Unruh-DeWitt detectors in a static BTZ black hole spacetime. Here, the effects coming from com…
Instant Extraction of Non-Perturbative Tripartite Entanglement
Diana Méndez Avalos, Kensuke Gallock-Yoshimura, Laura J. Henderson +1
We consider the problem of extracting tripartite entanglement through single local instantaneous interactions of a separable target system A-B-C with a scalar field. We find, non-p…
Entanglement Harvesting with a Twist
Laura J. Henderson, Su Yu Ding, Robert B. Mann
One consequence of the cosmic censorship conjecture is that any topological structure will ultimately collapse to within the horizons of a set of black holes, and as a result, an e…
