- Abstract: This study explores the transfer of nonclassical correlations from an
ultra-cold atom system to a pair of pulsed laser beams. Through nondestructive
local probe measurements, we introduce an alternative to destructive techniques
for mapping BEC entanglement. Operating at ultralow temperatures, the setup
emulates a relativistic vacuum field, using lasers as Unruh-DeWitt detectors
for phonons. The vacuum holds intrinsic entanglement, transferable to distant
probes briefly interacting with it - a phenomenon termed ``entanglement
harvesting''. Our study accomplishes two primary objectives: first,
establishing a mathematical equivalence between a pair of pulsed laser probes
interacting with an effective relativistic field and the entanglement
harvesting protocol; and second, to closely examine the potential and
persisting obstacles for realising this protocol in an ultra-cold atom
experiment.
