We study entanglement and squeezing of two uncoupled impurities immersed in a Bose-Einstein condensate. We treat them as two quantum Brownian particles interacting with a bath composed of the Bogoliubov modes of the condensate. The Langevin-like quantum stochastic equations derived exhibit memory effects. We study two scenarios: (i) In the absence of an external potential, we observe sudden death of entanglement; (ii) In the presence of an external harmonic potential, entanglement survives even at the asymptotic time limit. Our study considers experimentally tunable parameters.

In their replies to both referee reports, the authors have addressed all criticism. They have amended their manuscript accordingly. As I mentioned in my first report, I recommend publication of this manuscript in SciPost in its present form and without any further delay. I apologize for my late response to the reviewers reply.
