    • Coherence of an Optically Illuminated Single Nuclear Spin Qubit 

      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 ...
    • Coherent Spin Manipulation in an Exchange-Only Qubit 

      Laird, Edward A.; Taylor, Jacob Mason; Di Vincenzo, David P.; Marcus, Charles Masamed; Hanson, Micah P.; Gossard, Arthur C. (American Physical Society, 2010)
      Initialization, two-spin coherent manipulation, and readout of a three-spin qubit are demonstrated using a few-electron triple quantum dot. The three-spin qubit is designed to allow all operations for full qubit control ...
    • Dynamic Nuclear Polarization in Double Quantum Dots 

      Gullans, Michael John; Krich, Jacob Jonathan; Taylor, Jacob Mason; Bluhm, Hendrik; Halperin, Bertrand I.; Marcus, Charles Masamed; Stopa, Michael P; Yacoby, Amir; Lukin, Mikhail D. (American Physical Society, 2010)
      We theoretically investigate the controlled dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. Three regimes of long-term dynamics are identified, including the buildup of ...
    • Exchange Control of Nuclear Spin Diffusion in a Double Quantum Dot 

      Reilly, David J.; Taylor, Jacob Mason; Petta, Jason R.; Marcus, Charles Masamed; Hanson, Micah P.; Gossard, Arthur C. (American Physical Society, 2010)
      The influence of gate-controlled two-electron exchange on the relaxation of nuclear polarization in small ensembles \((N \sim 10^6)\) of nuclear spins is examined in a GaAs double quantum dot system. Waiting in the (2,0) ...
    • Quantum Repeater with Encoding 

      Jiang, Liang; Taylor, Jacob Mason; Nemoto, Kae; Munro, W J; Van Meter, Rodney; Lukin, Mikhail D. (American Physical Society, 2009)
      We propose an approach to implement quantum repeaters for long-distance quantum communication. Our protocol generates a backbone of encoded Bell pairs and uses the procedure of classical error correction during simultaneous ...
    • Qubit Protection in Nuclear-Spin Quantum Dot Memories 

      Kurucz, Z; Sørensen, M W; Taylor, Jacob Mason; Lukin, Mikhail D.; Fleischhauer, M (American Physical Society, 2009)
      We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the spin of the excess electron through the ...
    • Robust Optical Delay Lines with Topological Protection 

      Hafezi, Mohammad; Demler, Eugene A.; Lukin, Mikhail D.; Taylor, Jacob Mason (Nature Publishing Group, 2011)
      Phenomena associated with the topological properties of physical systems can be naturally robust against perturbations. This robustness is exemplified by quantized conductance and edge state transport in the quantum Hall ...
