Raising prospects for building a practical quantum computer, physicists at the National Institute of Standards and Technology (NIST) have demonstrated sustained, reliable information processing operations on electrically charged atoms (ions). The new work, described in the August 6 issue of Science Express,* overcomes significant hurdles in scaling up ion-trapping technology from small demonstrations to larger quantum processors.In the new demonstration, NIST researchers repeatedly performed...

A team of scientists has determined a way to make biomolecular computers think more "Ëœlogically'. Professor Ehud Shapiro of the Weizmann Institute's Biological Chemistry, and Computer Science and Applied Mathematics Departments led the first team to create an autonomous programmable DNA computing device in 2001. The first microscopic computing device was able to perform tasks such as checking a list of 0s and 1s to show whether or not there was an even number of 1s. In 2004, a new...

The first desktop computers changed the way we managed data forever. Three decades after their introduction, we rely on them to manage our time, social life and finances "” and to keep this information safe from prying eyes and online predators.So far, so good, despite an occasional breach. But our security and our data could be compromised overnight when the first quantum computer is built, says Dr. Julia Kempe of Tel Aviv University's Blavatnik School of Computer Science. These new...

U.S. scientists say they have developed a new algorithm that may advance data encryption capabilities. Researchers led by Princeton University Assistant Professor Jason Fleischer developed the so-called reversing algorithm after using a special optical device called a non-linear crystal, rather than an ordinary lens, to capture an image. Every image is made up of a collection of light waves, and a lens bends (refracts) the waves towards a detector, the scientists explained. In contrast, in...

U.S. scientists say they have rewritten algorithms to resolve delays of days or even years faced by researchers designing and simulating molecules. The time delay problem is caused by the amount of time a computer needs to run complex quantum mathematical equations, or algorithms, used during the development of more effective drugs, catalysts for fuel cells and other molecular-based materials and applications. Stanford University Professor Todd Martinez and graduate student Ivan Ufimtsev say...

A U.S.-led team of physicists says it has created the first rudimentary, solid-state quantum processor, moving science closer to building a quantum computer. Yale University scientists said they also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with a solid-state device for the first time. Our processor can perform only a few very simple quantum tasks, which have been demonstrated...

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...
