• Resumen: Multiparticle entangled states, essential ingredients for modern quantum technologies, are routinely generated in experiments of atomic Bose-Einstein condensates (BECs). However, entanglement in ultracold interacting Fermi gases has not been exploited yet. Using a theory of composite bosons we show that many-particle entanglement between two fermionic ensembles localized in spatially separated modes can be generated by splitting an ultracold interacting Fermi gas in the (molecular) BEC regime. This entanglement, which relies on the fundamental fermion exchange symmetry of molecular constituents, might be used for implementing quantum information tasks such as Bell test of quantum nonlocality. We predict that particle fluctuations on the single-particle spectral density can be almost perfectly correlated close to the unitarity regime and that large ensembles, of the order of 10^5 fully entangled fermionic atoms, could be generated in current experiments of ultracold interacting Fermi gases.
