Requirements for fault-tolerant factoring on an atom-optics quantum computer
Simon J. Devitt, Ashley M. Stephens, William J. Munro +1
Quantum information processing and its associated technologies has reached an interesting and timely stage in their development where many different experiments have been performed…
Coherent phonon manipulation in coupled mechanical resonators
Hajime Okamoto, Adrien Gourgout, Chia-Yuan Chang +4
Coupled mechanical oscillations were first observed in paired pendulum clocks in the mid-seventeenth century and were extensively studied for their novel sympathetic oscillation dy…
Fundamental limit to Qubit Control with Coherent Field
Kazuhiro Igeta, Nobuyuki Imoto, Masato Koashi
The ultimate accuracy as regards controlling a qubit with a coherent field is studied in terms of degradation of the fidelity by employing a fully quantum mechanical treatment. Whi…
Stochastic Formation of Polariton Condensates in Two Degenerate Orbital States
Kenichiro Kusudo, Na Young Kim, Andreas Loeffler +3
We explore the exciton-polariton condensation in the two degenerate orbital states. In the honeycomb lattice potential, at the third band we have two degenerate vortex-antivortex l…
A monolithically integrated polarization entangled photon pair source on a silicon chip
Nobuyuki Matsuda, Hanna Le Jeannic, Hiroshi Fukuda +6
Integrated photonic circuits are one of the most promising platforms for large-scale photonic quantum information systems due to their small physical size and stable interferometer…
Understanding the nature of luminous red galaxies (LRGs): Connecting LRGs to central and satellite subhalos
Shogo Masaki, Chiaki Hikage, Masahiro Takada +2
We develop a novel abundance matching method to construct a mock catalog of luminous red galaxies (LRGs) in SDSS, using catalogs of halos and subhalos in N-body simulations for a L…
