Dwave currently is testing a 128 qubit quantum computer processor. Overview and history of Dwave Dwave Processor architecture 38 page pdf Status* Have run optimization problems on C1 (8 qubit, 1500 JJs) …
Information technology is all around us — but how does it really change the way we do business? Erik Brynjolfsson, the Schussel Family Professor at MIT’s Sloan School of Management, explores this question in his new book, “Wired for Innovation,” written along with Adam Saunders, a lecturer at The Wharton School of the University of …
The Navy’s second littoral combat ship, the Independence, finished its builder’s trials Wednesday. The aluminum trimaran hit a top speed of 45 knots [50mph] and kept a sustained speed of 44 knots during its full power run in the Gulf of Mexico, shipbuilder General Dynamics said in an announcement. It kept a high speed and …
The holy grail in spintronics is to address spin with something other than magnets and now University of Ohio researchers provided a theoretical modeling for a recent experiment that was the first to successfully control an electron’s spin using purely electrical fields. The team collaborated with a research group at the University of Cincinnati, led …
A free-trade agreement between China and Taiwan could boost China’s gross domestic product growth by 0.36-0.4 percentage point and by 0.63-0.67 percentage point after the members of the Asean +3 trade bloc begin removing import tariffs as soon as 2010. Taiwan’s annual gross domestic product (GDP) will increase by an estimated 1.72 percent if Taiwan and …
BBC News reports on the impact of faster GPUs on the movie special effect business In the past, movie effects would be done in post-production and not be seen for weeks or even months after a movie has wrapped. All that is changing thanks to the GPU, according to leading industry players like Richard Kerris, …
Prof. Leonid Shvartsman and Prof. Boris Laikhtman of the university’s Racah Institute of Physics have invented a novel design of TeraHertz-ray (T-ray) lasers. They said the novel device will have 400 times higher “gain” (a measure of power) than that of the only coherent T-ray sources existing today, called THzQuantum cascade lasers. “The novel method …
Carnegie Mellon University is developing microwave-assisted magnetic recording (MAMR) technique he believes will pack three terabits of data in a square inch of a spinning disk. The next big shift in hard disk technology expected to emerge in the next year or two. Seagate Technology has been championing an approach called heat-assisted magnetic recording (HAMR) …
In the Grist article by Amory Lovins: “stewart brands nuclear enthusiasm falls short on facts and logic” In its first half-century, nuclear power fell short of its forecast capacity by about 12-fold in the U.S. and 30-fold worldwide, mainly because building it cost several-fold more than expected, straining or bankrupting its owners This is referring …
Amory Lovins wrote an article on Grist primarily making the case that nuclear power is not economic and has a 30+ page pdf on the “Four Myths of Nuclear” This will be the first of a few articles where I show where Lovins is wrong. Firstly he talks about gross dollar or energy amounts. Those …
1. Activelink, a subsidiary of Panasonic, is working on power enhancing partial exoskeletons This includes dual arm loaders (like in the Aliens 2 Movie), which will help someone lift 100 kilograms or more. They will not be ready for commercial use before 2015. Activelink also has powerwalker amplifiers, which are similar to springwalkers, power stilts …
