    • Effects of molecular resonances on Rydberg blockade 

      Derevianko, Andrei; Komar, Peter; Topcu, Turker; Kroeze, Ronen M.; Lukin, Mikhail D. (American Physical Society (APS), 2015)
      We study the effect of resonances associated with complex molecular interaction of Rydberg atoms on Rydberg blockade. We show that densely spaced molecular potentials between doubly excited atomic pairs become unavoidably ...
    • Heisenberg-Limited Atom Clocks Based on Entangled Qubits 

      Kessler, Eric; Komar, Peter; Bishof, M.; Jiang, L.; Sørensen, A. S.; Ye, J.; Lukin, Mikhail D. (American Physical Society (APS), 2014)
      We present a quantum-enhanced atomic clock protocol based on groups of sequentially larger Greenberger-Horne-Zeilinger (GHZ) states that achieves the best clock stability allowed by quantum theory up to a logarithmic ...
    • Heralded Quantum Gates with Integrated Error Detection in Optical Cavities 

      Borregaard, Johannes; Komar, Peter; Kessler, Eric; Sørensen, A. S.; Lukin, Mikhail D. (American Physical Society (APS), 2015)
      We propose and analyze heralded quantum gates between qubits in optical cavities. They employ an auxiliary qubit to report if a successful gate occurred. In this manner, the errors, which would have corrupted a deterministic ...
    • Long-distance entanglement distribution using individual atoms in optical cavities 

      Borregaard, Johannes; Komar, Peter; Kessler, Eric; Lukin, Mikhail D.; Sørensen, A. S. (American Physical Society (APS), 2015)
      Individual atoms in optical cavities can provide an efficient interface between stationary qubits and flying qubits (photons), which is an essential building block for quantum communication. Furthermore, cavity-assisted ...
    • Optomechanical Quantum Information Processing with Photons and Phonons 

      Stannigel, K.; Komar, Peter; Habraken, S. J. M.; Bennett, Steven; Lukin, Mikhail D.; Zoller, P.; Rabl, P. (American Physical Society, 2012)
      We describe how strong resonant interactions in multimode optomechanical systems can be used to induce controlled nonlinear couplings between single photons and phonons. Combined with linear mapping schemes between photons ...
    • Quantum Information Science and Quantum Metrology: Novel Systems and Applications 

      Kómár, Péter (2015-12-14)
      The current frontier of our understanding of the physical universe is dominated by quantum phenomena. Uncovering the prospects and limitations of acquiring and processing information using quantum effects is an outstanding ...
    • Single-photon nonlinearities in two-mode optomechanics 

      Komar, Peter; Bennett, Steven; Stannigel, K.; Habraken, S.; Rabl, P.; Zoller, P.; Lukin, Mikhail D. (American Physical Society, 2013)
      We present a detailed theoretical analysis of a weakly driven, multimode optomechanical system, in which two optical modes are strongly and near-resonantly coupled to a single mechanical mode via a three-wave mixing ...
