Journal ArticleDOI

A gravitational wave observatory operating beyond the quantum shot-noise limit

J. Abadie, +614 more
- 11 Sep 2011 - 
TL;DR: In this paper, the authors demonstrate the squeezed-light enhancement of GEO600, which will be the GW observatory operated by the LIGO Scientific Collaboration in its search for GWs for the next 3-4 years.
Journal ArticleDOI

A coherent Ising machine for 2000-node optimization problems.

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

A fully programmable 100-spin coherent Ising machine with all-to-all connections

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.
Journal ArticleDOI

Network of Time-Multiplexed Optical Parametric Oscillators as a Coherent Ising Machine

TL;DR: In this article, a network of four degenerate optical parametric oscillators (OPOs) is employed to find the ground state of the Ising Hamiltonian, and a small non-deterministic polynomial time-hard problem is solved on a 4-OPO Ising machine.
Journal ArticleDOI

Ultrahigh-efficiency wavelength conversion in nanophotonic periodically poled lithium niobate waveguides

TL;DR: In this article, a nanostructured PPLN waveguide was used to demonstrate an ultrahigh normalized efficiency of 2600%/W−cm2 for second-harmonic generation of 1.5μm radiation, more than 20 times higher than that in state-of-the-art diffused waveguides.
