Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. The work is published online today on the Science Express Web site. The researchers have demonstrated the ability to electrically manipulate, at gigahertz rates, the quantum states of electrons trapped on individual defects in diamond crystals. This could aid in the development of quantum computers that could use...

NEW YORK, Oct. 7 /PRNewswire/ -- Sometimes it's best to start at the beginning of any tough math problem. Assess the facts, apply core principles, and, well, do the math. So what's a student to do when "doing the math" turns into one in a series of illegible pieces of scrap paper? Scrap the paper and go online to TutaPoint.com, which recently released a complete suite of more than 100 short, concise videos that address core mathematics concepts. TutaPoint.com -- a Manhattan-based...

A new silicon chip the size of a penny uses photons to run Shor's algorithm - a well-known quantum approach - to solve mathematic problems, BBC News reported. Before the development, the algorithm required laboratory-sized optical computers to compute the two numbers that multiply together to form a given figure. Researchers say such factoring is the basis for a wide variety of encryption schemes and the new chip could easily be scaled up to handle more complex computing. Quantum computing...

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...

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...
