Entanglement production in the dynamical Casimir effect at parametric resonance
Ivan Romualdo, Lucas Hackl, Nelson Yokomizo
The particles produced from the vacuum in the dynamical Casimir effect are highly entangled. In order to quantify the correlations generated by the process of vacuum decay induced…

Minimal energy cost of entanglement extraction
Lucas Hackl, Robert H. Jonsson
We compute the minimal energy cost for extracting entanglement from the ground state of a bosonic or fermionic quadratic system. Specifically, we find the minimal energy increase $…
