    • All-Optical Sensing of a Single-Molecule Electron Spin 

      Sushkov, Alexander; Chisholm, N.; Lovchinsky, I.; Kubo, M.; Lo, P. K.; Bennett, Steven; Hunger, D.; Akimov, Alexey; Walsworth, Ronald Lee; Park, H.; Lukin, Mikhail D. (American Chemical Society (ACS), 2014)
      We demonstrate an all-optical method for magnetic sensing of individual molecules in ambient conditions at room temperature. Our approach is based on shallow nitrogen-vacancy (NV) centers near the surface of a diamond ...

    • Coherent Optical Transitions in Implanted Nitrogen Vacancy Centers 

      Chu, Y.; de Leon, Nathalie Pulmones; Shields, B.J.; Hausmann, B.; Evans, R.; Togan, E.; Burek, Michael John; Markham, M.; Stacey, A.; Zibrov, Alexander S; Yacoby, Amir; Twitchen, D.J.; Loncar, Marko; Park, H.; Maletinsky, P.; Lukin, Mikhail D. (American Chemical Society (ACS), 2014)
      We report the observation of stable optical transitions in nitrogen-vacancy (NV) centers created by ion implantation. Using a combination of high temperature annealing and subsequent surface treatment, we reproducibly ...

    • Deterministic Coupling of a Single Nitrogen Vacancy Center to a Photonic Crystal Cavity 

      Englund, Dirk; Shields, Brendan John; Rivoire, Kelley; Hatami, Fariba; Vučković, Jelena; Park, Hongkun; Lukin, Mikhail D. (American Chemical Society, 2010)
      We describe and experimentally demonstrate a technique for deterministic, large coupling between a photonic crystal (PC) nanocavity and single photon emitters. The technique is based on in situ scanning of a PC cavity over ...

    • Diamond nanophotonic quantum networks 

      Bhaskar, Mihir Keshav (2021-03-31)
      A coherent interface between optical photons and long-lived matter qubits can form the basis for a broad range of quantum technologies. I will describe the realization of such an interface using inversion-symmetric ...

    • Electron–phonon processes of the silicon-vacancy centre in diamond 

      Jahnke, Kay D; Sipahigil, Alp; Binder, Jan M; Doherty, Marcus W; Metsch, Mathias; Rogers, Lachlan J; Manson, Neil B; Lukin, Mikhail D.; Jelezko, Fedor (IOP Publishing, 2015)
      We investigate phonon induced electronic dynamics in the ground and excited states of the negatively charged silicon-vacancy (SiV−) centre in diamond. Optical transition line widths, transition wavelength and excited state ...

    • Experimental Realization of Improved Magnetic Sensing and Imaging in Ensembles of Nitrogen Vacancy Centers in Diamond 

      Hart, Connor (2020-09-10)
      Nitrogen-vacancy color centers in diamond constitute a leading quantum sensing platform, with particularly diverse applications in magnetometry. The negatively-charged NV center (NV) exhibits a long-lived electronic ...

    • Imaging Mesoscopic Nuclear Spin Noise with a Diamond Magnetometer 

      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, ...

    • Integrated Diamond Networks for Quantum Nanophotonics 

      Hausmann, Birgit Judith Maria; Shields, Brendan John; Quan, Qimin; Maletinsky, Patrick; McCutcheon, Murray; Choy, Jennifer Tze-Heng; Babinec, Tom M.; Kubanek, Alexander; Yacoby, Amir; Lukin, Mikhail D.; Loncar, Marko (American Chemical Society (ACS), 2012)
      We demonstrate an integrated nanophotonic network in diamond, consisting of a ring resonator coupled to an optical waveguide with grating in- and outcouplers. Using a nitrogen-vacancy color center embedded inside the ring ...
