Journal ArticleDOI

Jiun-Haw Chu,Jiun-Haw Chu,James Analytis,James Analytis,Kristiaan De Greve,Peter L. McMahon,Zahirul Islam,Yoshihisa Yamamoto,Yoshihisa Yamamoto,Ian R. Fisher,Ian R. Fisher +10 more
TL;DR: It is revealed that the representative iron arsenide Ba(Fe1−xCox)2As2 develops a large electronic anisotropy at this transition via measurements of the in-plane resistivity of detwinned single crystals, with the resistivity along the shorter b axis ρb being greater than ρa.
Journal ArticleDOI
A coherent Ising machine for 2000-node optimization problems.
Takahiro Inagaki,Yoshitaka Haribara,Yoshitaka Haribara,Koji Igarashi,Tomohiro Sonobe,Tomohiro Sonobe,Shuhei Tamate,Toshimori Honjo,Alireza Marandi,Peter L. McMahon,Takeshi Umeki,Koji Enbutsu,Osamu Tadanaga,Hirokazu Takenouchi,Kazuyuki Aihara,Ken-ichi Kawarabayashi,Ken-ichi Kawarabayashi,Kyo Inoue,Shoko Utsunomiya,Hiroki Takesue +19 more
TL;DR: It is shown that an optical processing approach based on a network of coupled optical pulses in a ring fiber can be used to model and optimize large-scale Ising systems, and a coherent Ising machine outperformed simulated annealing in terms of accuracy and computation time for a 2000-node complete graph.
Journal ArticleDOI

TL;DR: The present technique advances the III–V semiconductor quantum-dot spin system as a promising platform for long-distance quantum communication by frequency downconversion of a spontaneously emitted photon from a singly charged quantum dot to a wavelength of 1,560 nanometres.
Journal ArticleDOI
A fully programmable 100-spin coherent Ising machine with all-to-all connections
Peter L. McMahon,Peter L. McMahon,Alireza Marandi,Yoshitaka Haribara,Yoshitaka Haribara,Ryan Hamerly,Carsten Langrock,Shuhei Tamate,Takahiro Inagaki,Hiroki Takesue,Shoko Utsunomiya,Kazuyuki Aihara,Robert L. Byer,Martin M. Fejer,Hideo Mabuchi,Yoshihisa Yamamoto +15 more
TL;DR: In this article, a scalable optical processor with electronic feedback that can be realized at large scale with room-temperature technology is presented. But it is not suitable for large-scale combinatorial optimizations.
