USC scientists demonstrate that quantum computing could speed up the way web page ranks are calculated on the ever-expanding Internet Most people don't think twice about how Internet search engines work. You type in a word or phrase, hit enter, and poof — a list of web pages pops up, organized by relevance. Behind the scenes, a lot of math goes into figuring out exactly what qualifies as most relevant web page for your search. Google, for example, uses a page ranking algorithm...

Inexpensive Magnetic Field Sensor From 'Plastic Paint'
2012-06-12 12:38:48

Spintronic device uses thin-film organic semiconductor University of Utah physicists developed an inexpensive, highly accurate magnetic field sensor for scientific and possibly consumer uses based on a "spintronic" organic thin-film semiconductor that basically is "plastic paint." The new kind of magnetic-resonance magnetometer also resists heat and degradation, works at room temperature and never needs to be calibrated, physicists Christoph Boehme, Will Baker and colleagues report...

Quantum Computers Move One Step Closer
2012-06-08 03:00:53

The quantum computer is a futuristic machine that could operate at speeds even more mind-boggling than the world´s fastest super-computers. Research involving physicist Mike Thewalt of Simon Fraser University offers a new step towards making quantum computing a reality, through the unique properties of highly enriched and highly purified silicon. Quantum computers right now exist pretty much in physicists´ concepts, and theoretical research. There are some basic quantum...

Expert Predicts Quantum Computing Technology Could Be Near
2012-05-07 04:02:49

A prominent theoretical physicist and the co-author of a book on quantum mechanics believes that research in the field of quantum computing is rapidly progressing, and that the technology is inching ever closer to becoming a reality. In a column written for the Guardian on Saturday, Jeff Forshaw, co-author of the 2011 book 'The Quantum Universe: Everything That Can Happen Does Happen' and a professor at the University of Manchester, said, "Quantum simulations have, in the past year, really...

Theoretical Physicist Michio Kaku: The End Is Near For Moore’s Law
2012-05-01 09:03:39

Brett Smith for Redorbit.com The days of Moore´s Law, which says computer processing capability doubles every 18 months, could be coming to a close according to theoretical physicist Michio Kaku. In a video produced for BigThink.com, Kaku said the smaller and smaller silicon chips that companies are producing might soon reach their processing limits. Once a chip´s layer of silicon reaches the size of about 5 atoms across it will begin to suffer from two particular...

New device, developed by team of engineers led by Professor Amr Helmy (ECE), could bring quantum computing to your home or office In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now. Thanks to the work by a team of engineers led by Professor Amr Helmy of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, a novel solution has been identified that will...

NIST Physicists Benchmark Quantum Simulator With Hundreds Of Qubits
2012-04-25 11:32:05

Physicists at the National Institute of Standards and Technology (NIST) have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits)–10 times more than previous devices. As described in the April 26 issue of Nature*, the simulator has passed a series of important benchmarking tests and scientists are poised to study problems in material science that are impossible to model on conventional computers. Many important problems in...

Paper offers a mathematical formulation of the brain's neural networks As computer scientists this year celebrate the 100th anniversary of the birth of the mathematical genius Alan Turing, who set out the basis for digital computing in the 1930s to anticipate the electronic age, they still quest after a machine as adaptable and intelligent as the human brain. Now, computer scientist Hava Siegelmann of the University of Massachusetts Amherst, an expert in neural networks, has taken...

Image 1 - Algorithm Paves Way For Future 'Smart Sand'
2012-04-03 04:55:18

Lee Rannals for Redorbit.com Researchers from MIT have developed new algorithms that could enable "Smart Sand" to form into any shape. By using the algorithm, individual Smart Sand grains would be able to communicate to one another, forming a three-dimensional object. As messages are passed back and forth to each of the grains, they selectively attach to each other to form an object, while the unused grains simply fall away. Once the object has served its purposed, the smart sand...

Algorithm
2013-12-16 10:46:30

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states and eventually...
