Manipulating Quantum Bits for Cybersecurity

Feb 18, 2014 |

Quantum computing holds the promise of improving cyber security infrastructure.  Security algorithms such as those used in online banking require basic primitive operations such as factoring numbers. To improve security, larger numbers must be used resulting in a substantial increase in computational requirements. Duncan Steel, professor of Electrical Engineering and Computer Science, Physics, and Biophysics 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…

Everything You Always Wanted to Ask D-Wave

Jan 13, 2014 |

Whether or not the D-Wave quantum computer is in actuality a quantum computer is a debate that HPCwire has been following since the project hatched in 2007. Early critics of the system claimed that it wasn’t a “real” quantum computer. Since that time, D-Wave has been winning over supporters, including Google, NASA and Lockheed Martin. Read more…

The Promise of Quantum Money

Jan 7, 2014 |

In their continuing efforts to stop counterfeiting the United States Federal Reserve released a newly-designed $100 note with an eye-popping color palette. The newest iteration sports a decade’s worth of security advances, anti-counterfeiting measures such as holograms, raised printing and artifacts that appear to move and change color depending on the viewing angle. Despite these Read more…

UK Invests £270 Million in Quantum Computing

Dec 11, 2013 |

Last week, the UK government announced that it is investing £270 million toward quantum computing research as part of the government’s long-term economic plan. The funds will be divided among five quantum technology centers over the next five years. The initiative was announced as part of Chancellor George Osborne’s Autumn Statement, delivered last week in Read more…

Carver Mead on Quantum Computing and Neuromorphic Design

Nov 25, 2013 |

Computer scientist, inventor and university physicist Carver Mead is perhaps best known for coining the phrase “Moore’s law,” helping to popularize Gordon Moore’s 1965 observation that the number of transistors on an integrated circuit doubles about every 24 months. Mead was also instrumental in the prediction’s tremendous staying power. One of Mead’s most significant contributions 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…

Toward Stable Quantum Computing

Sep 18, 2013 |

What good is computing if it’s not reliable? An international team of researchers just got a little closer to realizing the grand challenge that is practical quantum computing.
