DOI: 10.1007/s11128-018-2061-0
Abstract: We present an explicit family of two-qubit X states with entanglement-preserving unitary equivalence to the set of general states; that is, for any spectrum–entanglement combination achievable by general states, this family contains an X state… read more here.

DOI: 10.1103/physreva.99.063601
Abstract: Multiparticle entangled states, essential ingredients for modern quantum technologies, are routinely generated in experiments of atomic Bose-Einstein condensates (BECs). However, the entanglement in ultracold interacting Fermi gases has not been yet exploited. In this work,… read more here.
