WASHINGTON Duke Johnson Jr Browns Jersey , 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 Nate Orchard Browns Jersey , works on a large matrix of data and has kick-started research into quantum forms of machine learning, 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 Antonio Callaway Browns Jersey , 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, 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 Chad Thomas Browns Jersey , 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.

BEIJING Duke Johnson Jr Jersey , Feb. 2 (Xinhua) -- Chinese President Xi Jinping Friday met all delegates to the third Party congress of the armed police force in Beijing.


Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission (CMC), expressed congratulations on the convening of the congress and extended greetings to the delegates and all officers and servicemen of the armed police force.


The congress was convened with approval from the CMC after the transfer of command of the armed police force from the State Council to the CPC Central Committee and the CMC starting from Jan. 1, 2018.


The main task of the congress is to implement Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era and the spirit of the 19th CPC National Congress as well as Xi's thought on making the armed forces stronger.

Golf is a game of inches, you might have heard that term before but there is the theory of golf that is equally as important as the mechanics of the game. I will start with some history followed by golf terms and meanings.

The first game of golf for which records survive was played at Bruntsfield Links, in Edinburgh Nate Orchard Jersey , Scotland. The word golf was first mentioned in writing in 1457 on a Scottish statute on forbidden games as gouf, possibly derived from the Scots word goulf meaning to strike or cuff.

But there is an even earlier reference to the game of golf and it is believed to have happened in 1452 when King James II banned the game because it kept his subjects from their archery practice. The origin of golf is open to debate as to being Chinese, Dutch or Scottish. However, the most accepted golf history theory is that this sport originated from Scotland in the 1100s.

The word golf derives from the Dutch kolf meaning stick, club or bat. The oldest playing golf course in the world is The Old Links at Musselburgh Racecourse. As early as the 15th century, golfers at St Andrews Antonio Callaway Jersey , in Fife, established a customary route through the undulating terrain, playing to holes whose locations were dictated by topography.

In 2005 Golf Digest calculated that there were nearly 32,000 golf courses in the world, approximately half of them in the United States. A typical golf course consists of eighteen holes, but many only have nine. Every game of golf is based on playing a number of holes in a given order.

A hole of golf consists of hitting a ball from a tee on the teeing box Chad Thomas Jersey , a marked area designated for the first shot of a hole called a tee shot, and once the ball comes to rest, striking it again. A hole is classified by its par, the number of strokes a skilled golfer should require to complete play to the hole.

For example, a skilled golfer expects to reach the green on a par four hole in two strokes, one from the tee called the drive and another stroke to the green called the approach. Once on the green the player rolls the ball into the hole with two putts. Traditionally Shon Coleman Browns Jersey , a golf hole is a par-three,.
