|WASHINGTON Women's Nike Air Force 1 Explorer XX Geode Teal , Feb. 2 (Xinhua) -- An international team has shown that quantum computers can analyze relationships within large sets of data faster than classical computers, for a wider array of data types than previously expected.
The study, published on Friday in American journal Physical Review Letters, proposed a "quantum linear system algorithm" that could conduct quantum computation with application in artificial intelligence (AI) and crunch numbers on problems such as commodities pricing, social networks and chemical structures.
The linear system algorithm, first proposed in 2009, works on a large matrix of data and has kick-started research into quantum forms of machine learning Women's Nike Air Force 1 High Green , or artificial intelligence.
"There is a lot of computation involved in analyzing the matrix. When it gets beyond say 10,000 by 10,000 entries, it becomes hard for classical computers," explained Zhao Zhikuan, the paper's corresponding author from Singapore University of Technology and Design.
Zhao also said the previous quantum algorithm of this kind can be applied to a very specific type of problem. This is because the number of computational steps goes up rapidly with the number of elements in the matrix: every doubling of the matrix size increases the length of the calculation eight-fold.
Zhao and his colleague in Singapore, Switzerland and the United Kingdom Women's Nike Air Force 1 Low Red , present a new algorithm that is faster than both the classical and the previous quantum versions.
It relies on a technique known as quantum singular value estimation and can cope with data not limited to "sparse" ones as required by the previous versions.
There are limited relationships among the elements in sparse data, but it is often not true of real-world data, Zhao said.
For example, a trader might be trying to predict the future price of goods. The matrix may capture historical data about price movements over time and data about features that could be influencing these prices, such as exchange rates.
Then the algorithm calculates how strongly each feature is correlated with another by "inverting" the matrix. This information can then be used to extrapolate into the future.
But to show a real quantum advantage over the classical algorithms will need bigger quantum computers.
Zhao estimates that it still need additional three to five years when they can actually use the hardware to do meaningful quantum computation with application in artificial intelligence.

"Guys, my Chinese name is not Panda Friend Women's Nike Air Force 1 Upstep LX White Black , it's The Panda's Friend," read the post from the online tag @MettaWorldPeace.
Meanwhile, China's social media kept up the red-hot buzz on World Peace news. The topic "World Peace signs with CBA" reached 26.97 million hits on Sina Weibo by Friday afternoon and a new topic "World Peace changes name" has now received 86.3 million hits.
Followers of the account called "Metta_World_Peace" have reached 967,860, over 600 people's increase from two days ago.
World Peace, who played for the Lakers from 2009-2010 through 2012-2013, changed his name from Ron Artest by filing a legal petition in September 2011.
Known in China as "Ci Shiping" Women's Nike Air Force 1 Reimagined Rebel XX All White , a literal translation of "Metta World Peace", the form. http://wholesalesoccercheapjerseys.com/ Wholesale NHL Jerseys Free Shipping Wholesale Jerseys Online Wholesale Jerseys From China Wholesale Basketball Jerseys China Wholesale Baseball Jerseys Wholesale Soccer Jerseys From China Wholesale Hockey Jerseys China Wholesale Custom Nike NFL Jerseys Wholesale Throwback College Jerseys
