Pulsed Nuclear Pumping and Spin Diffusion in a Single Charged Quantum Dot
Thaddeus D. Ladd, David Press, Kristiaan De Greve +7
We report the observation of a feedback process between the nuclear spins in a single charged quantum dot and its trion transition, driven by a periodic sequence of optical pulses.…
Observation of TeV Gamma Rays from the Fermi Bright Galactic Sources with the Tibet Air Shower Array
M. Amenomori, X. J. Bi, D. Chen +81
Using the Tibet-III air shower array, we search for TeV gamma-rays from 27 potential Galactic sources in the early list of bright sources obtained by the Fermi Large Area Telescope…
Tunable photon-assisted bleaching of three-level systems for noise filtration
Chun-Hsu Su, Andrew D. Greentree, Raymond G. Beausoleil +4
Electromagnetically-induced transparency (EIT) exploits quantum coherence to burn subnatural linewidth holes within a spectral line. We investigate the less explored properties of…
AstroSim: Collaborative Visualization of an Astrophysics Simulation in Second Life
Arturo Nakasone, Helmut Prendinger, Simon Holland +3
We introduce AstroSim, a Second Life based prototype application for synchronous collaborative visualization targeted at astronomers.
In-plane electronic anisotropy in underdoped Ba(FeCo)As revealed by detwinning in a magnetic field
Jiun-Haw Chu, James G. Analytis, David Press +4
We present results of angle-dependent magnetoresistance measurements and direct optical images of underdoped Ba(FeCo)As which reveal partial detwinning by actio…
Intracavity weak nonlinear phase shifts with single photon driving
W. J. Munro, K. Nemoto, G. J. Milburn
We investigate a doubly resonant optical cavity containing a Kerr nonlinear medium that couples two modes by a cross phase modulation. One of these modes is driven by a single phot…
The entanglement beam splitter: a quantum-dot spin in a double-sided optical microcavity
C. Y. Hu, W. J. Munro, J. L. O'Brien +1
We propose an entanglement beam splitter (EBS) using a quantum-dot spin in a double-sided optical microcavity. In contrast to the conventional optical beam splitter, the EBS can di…
From quantum fusiliers to high-performance networks
W. J. Munro, K. A. Harrison, A. M. Stephens +2
Our objective was to design a quantum repeater capable of achieving one million entangled pairs per second over a distance of 1000km. We failed, but not by much. In this letter we…
Adiabatic quantum computation along quasienergies
Atushi Tanaka, Kae Nemoto
The parametric deformations of quasienergies and eigenvectors of unitary operators are applied to the design of quantum adiabatic algorithms. The conventional, standard adiabatic q…
Higher order coherence of exciton-polariton condensates
Tomoyuki Horikiri, Paolo Schwendimann, Antonio Quattropani +3
The second and third order coherence functions of an exciton-polariton condensate is measured and compared to the theory. Contrary to an ideal photon…
Surface code quantum communication
Austin G. Fowler, David S. Wang, Charles D. Hill +3
Quantum communication typically involves a linear chain of repeater stations, each capable of reliable local quantum computation and connected to their nearest neighbors by unrelia…
