    • Dissipative Preparation of Spin Squeezed Atomic Ensembles in a Steady State 

      Dalla Torre, Emanuele; Otterbach, Johannes; Demler, Eugene A.; Vuletic, Vladan; Lukin, Mikhail D. (American Physical Society (APS), 2013)
      We present and analyze a new approach for the generation of atomic spin-squeezed states. Our method involves the collective coupling of an atomic ensemble to a decaying mode of an open optical cavity. We demonstrate the ...
    • Phonon-Induced Spin-Spin Interactions in Diamond Nanostructures: Application to Spin Squeezing 

      Bennett, Steven; Yao, Norman Ying; Otterbach, Johannes; Zoller, P.; Rabl, P.; Lukin, Mikhail D. (American Physical Society (APS), 2013)
      We propose and analyze a novel mechanism for long-range spin-spin interactions in diamond nanostructures. The interactions between electronic spins, associated with nitrogen-vacancy centers in diamond, are mediated by ...
    • Photon-Photon Interactions via Rydberg Blockade 

      Gorshkov, Alexey Vyacheslavovich; Otterbach, Johannes; Fleischhauer, Michael; Pohl, Thomas; Lukin, Mikhail D. (American Physical Society, 2011)
      We develop the theory of light propagation under the conditions of electromagnetically induced transparency in systems involving strongly interacting Rydberg states. Taking into account the quantum nature and the spatial ...
    • Photonic Phase Gate via an Exchange of Fermionic Spin Waves in a Spin Chain 

      Gorshkov, Alexey Vyacheslavovich; Otterbach, Johannes; Demler, Eugene A.; Fleischhauer, Michael; Lukin, Mikhail D. (American Physical Society, 2010)
      We propose a new protocol for implementing the two-qubit photonic phase gate. In our approach, the pi phase is acquired by mapping two single photons into atomic excitations with fermionic character and exchanging their ...
