Harvesting correlations from thermal and squeezed coherent states
Petar Simidzija, Eduardo Martin-Martinez
We study the harvesting of entanglement and mutual information by Unruh-DeWitt particle detectors from thermal and squeezed coherent field states. We prove (for arbitrary spatial d…

General no-go theorem for entanglement extraction
Petar Simidzija, Robert H. Jonsson, Eduardo Martin-Martinez
We study under what circumstances a separable bipartite system A-B can or cannot become entangled through local interactions with a bi-local entangled source -$\text{S}…
