Qutrits Bring Quantum Computers Closer 66

Posted by kdawson from the shortcut-through-higher-dimensions dept.
KentuckyFC writes "To do anything useful with quantum logic gates, you need dozens to hundreds of them, all joined together. And because of various errors and problems that creep in, that's more or less impossible with today's technology. Now an Australian group has built and tested logic gates that convert qubits into qutrits (three-level quantum states) before processing and then convert them back again. That makes them far more powerful. The group says that a quantum computer that might require 50 conventional quantum logic gates can now be built with just 9 of the new gates. What's more, the gates process photons using nothing more than standard linear optical components (abstract on the physics arxiv)."

Artificial Intelligence at Human Level by 2029? 678

Posted by Zonk from the i-need-me-an-implanted-robot-buddy dept.
Gerard Boyers writes "Some members of the US National Academy of Engineering have predicted that Artificial Intelligence will reach the level of humans in around 20 years. Ray Kurzweil leads the charge: 'We will have both the hardware and the software to achieve human level artificial intelligence with the broad suppleness of human intelligence including our emotional intelligence by 2029. We're already a human machine civilization, we use our technology to expand our physical and mental horizons and this will be a further extension of that. We'll have intelligent nanobots go into our brains through the capillaries and interact directly with our biological neurons.' Mr Kurzweil is one of 18 influential thinkers, and a gentleman we've discussed previously. He was chosen to identify the great technological challenges facing humanity in the 21st century by the US National Academy of Engineering. The experts include Google founder Larry Page and genome pioneer Dr Craig Venter."

Delays to Canadian DMCA Could Doom Act 128

Posted by Zonk from the getting-late-in-the-day dept.
Jabbrwokk writes "Michael Geist reports legislation to create a Canadian version of the Digital Millennium Copyright Act has been delayed again, possibly because of massive public outcry, and possibly even because of opposition from the industry itself. Canada's biggest ISPs have banded together to oppose the proposed new legislation and suggest their own solution, which include allowances for expanded fair dealing, private copying, no liability for ISPs and legislation that concentrates its wrath on commercial pirates instead of penny-ante downloaders and seeders.'"

Four Indicted in Pirate Bay Case 709

Posted by Zonk from the yo-ho-yo-ho-a-pirate's-life-for-awwww dept.
paulraps writes "Suddenly the founders of the Pirate Bay are not so hearty. The four men behind the popular file-sharing site were indicted in Sweden on Thursday on charges of being accessories to breaking copyright law. And this is more than just a shot across the bows. The prosecutor reckons that they can be hooked for 'promoting other people's copyright breaches' but there will be no walking the plank: instead, they face fines of up to $200,000 and the confiscation of all their hardware. 'The Swedish prosecutor listed dozens of works that had been downloaded through The Pirate Bay site, including The Beatles' Let It Be, Robbie Williams' Intensive Care and the movie Harry Potter & The Goblet of Fire. Plaintiffs in the case include Warner, MGM, Columbia Pictures, 20th Century Fox Films, Sony BMG, Universal and EMI.'"
