      Jiang, Liang; Brennen, Gavin; Gorshkov, Alexey Vyacheslavovich; Hammerer, Klemens; Hafezi, Mohammad; Demler, Eugene A.; Luki, Mikhail; Zoller, Peter (Nature Publishing Group, 2008)
      Strongly correlated quantum systems can exhibit exotic behavior called topological order which is characterized by non-local correlations that depend on the system topology. Such systems can exhibit remarkable phenomena ...

      Cappellaro, Paola; Jiang, Liang; Hodges, J. S.; Lukin, Mikhail D. (American Physical Society, 2009)
      We consider a protocol for the control of few-qubit registers comprising one electronic spin embedded in a nuclear spin bath. We show how to isolate a few proximal nuclear spins from the rest of the bath and use them as ...

      Jiang, Liang; Dutt, M. V. Gurudev; Togan, Emre Ismail Cengiz; Childress, Lily; Cappellaro, Paola; Taylor, Jacob Mason; Lukin, Mikhail D. (American Physical Society, 2008)
      We investigate the coherence properties of individual nuclear spin quantum bits in diamond [Dutt et al., Science, 316, 1312 (2007)] when a proximal electronic spin associated with a nitrogen-vacancy (NV) center is being ...

      Gorshkov, Alexey Vyacheslavovich; Jiang, Liang; Greiner, Markus; Zoller, Peter; Lukin, Mikhail D. (American Physical Society, 2008)
      We suggest a new method for quantum optical control with nanoscale resolution. Our method allows for coherent far-field manipulation of individual quantum systems with spatial selectivity that is not limited by the wavelength ...

      Lukin, Mikhail D.; Goldstein, Garry; Jiang, Liang; Maze, Jero R.; Sørenson, Anders S.; Cappellaro, Paola; Hodges, J. S. (American Physical Society, 2011)
      We describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit ...

      Brask, Jonatan; Jiang, Liang; Gorshkov, Alexey Vyacheslavovich; Vuletic, Vladan; Sorensen, Anders; Lukin, Mikhail D. (American Physical Society, 2010)
      Quantum repeaters based on atomic ensemble quantum memories are promising candidates for achieving scalable distribution of entanglement over long distances. Recently, important experimental progress has been made toward ...
    • Global Operations For Protected Quantum Memories In Atomic Spin Lattices 

      Brennen, Gavin K.; Hammerer, Klemens; Jiang, Liang; Lukin, Mikhail D.; Zoller, Peter (2009)
      Quantum information processed in strongly correlated states of matter can provide built in hardware protection against errors. We may encode information in highly non local degrees of freedom, such as using three dimensional ...

      Meriles, Carlos A.; Jiang, Liang; Goldstein, Garry; Hodges, Jonathan S.; Maze, Jeronimo; Lukin, Mikhail D.; Cappellaro, Paola (American Institute of Physics, 2010)
      Magnetic resonance imaging can characterize and discriminate among tissues using their diverse physical and biochemical properties. Unfortunately, submicrometer screening of biological specimens is presently not possible, ...

      Jiang, Liang; Rey, Ana Maria; Romero-Isart, Oriol; García-Ripoll, Juan José; Sanpera, Anna; Lukin, Mikhail D. (Ameican Physical Society, 2009)
      We present a protocol to prepare decoherence-free cluster states using ultracold atoms loaded in a two dimensional superlattice. The superlattice geometry leads to an array of 2×2 plaquettes, each of them holding four ...
