IBM Advances Silicon Photonics, Quantum Computing

May 14, 2015 |

Engineers at IBM have developed a fully integrated wavelength multiplexed silicon photonics chip, which the company says will soon enable manufacturing of 100 Gb/s optical transceivers. The advance promises to offer a more economical way to move the huge amounts of data required for cloud computing and big data applications. It’s a significant milestone for Read more…

Aerospace Explores the Compute Horizon

Sep 4, 2014 |

For much of the history of aviation, designers and engineers ran their calculations and experiments without the benefit of computers. But as the price of computation dropped, the competitive advantage conferred by digital engineering became clear. The aerospace industry has reached a turning point where the complexity of the simulation work is necessitating an increase in the Read more…

Scientists Devise Photon-based Router

Jul 16, 2014 |

Scientists at the Weizmann Institute say they have developed the world’s first photonic router, an important advance towards building a full-on quantum computer. The router is a quantum device based on a single atom that can switch between two states. The single atom is coupled to a fiber-coupled, chip-based microresonator. The state is flipped by Read more…

Quantum Processor Hits 99.9 Percent Reliability Target

Apr 25, 2014 |

Physicists at UC Santa Barbara (UCSB) have taken a huge leap forward towards what they refer to as a “fully functional quantum computer” – long-considered the holy grail of both physics and computing. The five cross-shaped elements are the Xmon variant, so named by the team, of the transmon qubit placed in a linear array. A Read more…

Big Leap Forward for Integrated Quantum Computer

Feb 5, 2014 |

An international team of researchers led by Dr. Mark Thompson from the University of Bristol have for the first time successfully generated and manipulated single photons on a silicon chip – putting them substantially closer to realizing their goal of building a quantum computer. The technique involved shrinking the key components so they could be Read more…

China Prepares for Quantum Age

Jan 24, 2014 |

Exascale isn’t the only international computing race currently underway. Around the world national interests are also scrambling to build quantum computers capable of making and breaking amazingly-complex codes. Take China for example. Already home to the most powerful supercomputer in the world, Tianhe-2, researchers in China have set their sites on the holy grail of Read more…

D-Wave Aims to Beat Any Classical Computer

Jan 23, 2014 |

For those of you following the D-Wave story, the designers of “the world’s first commercial quantum computer” have published a revealing blog entry detailing the company’s latest achievements. When Canadian startup D-Wave announced back in 2007 that it had developed a prototype quantum computing machine suitable for running commercial applications, the technical community paid attention, Read more…

Behind the Scenes at Google’s Quantum AI Lab

Oct 23, 2013 |

“If you think you understand quantum physics, you don’t understand quantum physics.” — Richard Feynman, Quantum Theorist The first commercial quantum computer was pioneered by Canadian firm D-Wave Systems, which unveiled its first prototype, a 16-qubit superconducting adiabatic quantum processor, in 2008. This novel type of superconducting processor uses quantum mechanics to massively accelerate computation. Read more…
