    • Bounding the Set of Finite Dimensional Quantum Correlations 

      Navascués, M.; Vértesi, T. (American Physical Society, 2015)
      We describe a simple method to derive high performance semidefinite programing relaxations for optimizations over complex and real operator algebras in finite dimensional Hilbert spaces. The method is very flexible, easy ...
    • Quantum correlated light pulses from sequential superradiance of a condensate 

      Taşgin, M.E.; Oktel, M. Ö.; You L.; MüstecaplIoǧlu Ö.E. (2009)
      We discover an inherent mechanism for entanglement swap associated with sequential superradiance from an atomic Bose-Einstein condensate. Based on careful examinations with both analytical and numerical approaches, we ...
    • Quantum correlations among superradiant bose-einstein condensate atoms 

      Taşgin, M. E.; Öztop, B.; Oktel, M. Ö.; Müstecapliog̃lu, Ö. E. (M A I K Nauka - Interperiodica, 2010)
      Quantum correlations among atoms in superradiant Bose-Einstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to ...
    • Quantum correlations of spin-1 atoms in an optical lattice 

      Öztop, B.; Oktel, M. Ö.; Müstecaplioǧlu, Ö. E. (Institute of Physics Publishing, 2009)
      In this work, we investigate the system of cold spin-1 atoms in a one dimensional optical lattice in relation with squeezing and entanglement. By using the corresponding Bose-Hubbard Hamiltonian, both superfluid and ...
    • Quantum entanglement of spin-1 bosons with coupled ground states in optical lattices 

      Öztop, B.; Oktel, M. Ö.; Müstecapliolu, Ö. E.; You, L. (IOP Institute of Physics Publishing, 2009)
      We examine particle entanglement, characterized by pseudo-spin squeezing, of spin-1 bosonic atoms with coupled ground states in a one-dimensional optical lattice. Both the superfluid and Mott-insulator phases are investigated ...
    • Quantum entanglement via superradiance of a Bose-Einstein condensate 

      Taşgın, M. E.; Oktel, M. Ö.; You, L.; Müstecaploǧlu, Ö. E. (Institute of Physics PublishingInstitute of Physics Publishing, 2010)
      We adopt the coherence and built-in swap mechanism in sequential superradiance as a tool for obtaining continuous-variable (electric/magnetic fields) quantum entanglement of two counter-propagating pulses emitted from the ...
