Harvesting correlations from the quantum vacuum
A Pozas-Kerstjens, E Martin-Martinez - Physical Review D, 2015 - APS
We analyze the harvesting of entanglement and classical correlations from the quantum
vacuum to particle detectors. We assess the impact on the detectors' harvesting ability of the …

Entanglement harvesting from the electromagnetic vacuum with hydrogenlike atoms
A Pozas-Kerstjens, E Martín-Martínez - Physical Review D, 2016 - APS
We study how two fully featured hydrogenlike atoms harvest entanglement from the
electromagnetic field vacuum, even when the atoms are spacelike separated. We compare …

Entanglement swapping between photons that have never coexisted
The role of the timing and order of quantum measurements is not just a fundamental
question of quantum mechanics, but also a puzzling one. Any part of a quantum system that …
