It would far outstrip any regime past or present in how intimately it records the lives of its citizens. Private conversations, family photos, and records of road trips, births, marriages, and deaths all stream into the company
Quantum PageRank Algorithm Outperforms Classical Version
A quantum version of Google’s famous search algorithm could one day make web searches faster, say computer scientists Google’s PageRank algorithm is the idea that the importance of a webpage can be measured by the number of important papers that point towards it. Sergey Brin and Larry Page applied the process to search engine rankings in 1998 and have since modified it in various ways that have ma
Massively Parallel Computer Built From Single Layer of Molecules
Modern computer chips handle data at the mind-blowing rate of some 10^13 bits per second. Neurons, by comparison, fire at a rate of around 100 times per second or so. And yet the brain outperforms the best computers in numerous tasks. In the brain, however, many calculations take place at once. Each neuron communicates with up to 1000 other neurons at any one time. And since the brain consists of
Reprogrammable Chips Could Enable Instant Gadget Upgrades - MIT Technology Review
Obsolescence is the curse of electronics: no sooner have you bought a gadget than its hardware is outdated. A new, low cost type of microchip that can rearrange its design on the fly could change that. The logic gates on the chip can be reconfigured to implement an improved design as soon as it becomes available—the hardware equivalent of the software upgrades often pushed out to gadgets like phon
