BEIJING [url=http://www.airmax97sale.com/air-vapormax-97-japan-black-neon-green-sale.html]Air VaporMax 97 Japan Black Neon Green Sale[/url] , Oct. 2 (Xinhua) -- After saying nihao, or hello, to his Austrian counterpart some 7,000 kilometers away, Bai Chunli, president of the Chinese Academy of Sciences, completed the world's first intercontinental quantum communication in Beijing.

The dialogue between Bai and Anton Zeilinger, Austrian quantum physicist and President of the Austrian Academy of Sciences, on Sept. 29 could be ultra-secret if they keep it private between them.

Encrypted by quantum communication technology, what they said could not be wiretapped, intercepted or cracked.

Bai's greeting was first sent out through a control center in Beijing along the Beijing-Shanghai Trunk Line, the first of its kind for secure quantum telecommunication open for use the same day.

The 2,000-km trunk line had been connected through a ground station to the world's first quantum satellite Micius launched by China in August last year.

Micius was named after a fifth century B.C. Chinese philosopher and scientist who was credited as the first person to conduct optical experiments.

During their talk, Zeilinger expressed congratulations on the achievements Chinese scientists made in quantum communication and hoped to strengthen cooperation.

Earlier that day, Bai had video talks with staff in Hefei, Jinan, Shanghai and Urumqi ground stations through the trunk line.

Pan Jianwei, chief scientist of the trunk line, said the video call between Bai and Zeilinger involved a long distance and multiple nodes.

Given that some nodes were not built by Chinese scientists, the tests showed the ground-space quantum communication network was stable, compatible and good for practical use, said Pan.

Chinese businesses, including the Bank of Communications, the Industrial and Commercial Bank of China (ICBC) and Alibaba, have used the quantum communication technology for information transmission.

Zhu Yu, deputy head of the China Information Industry Association, expected the tests would attract more companies into the sector of quantum communication, and a brand new industrial chain would come into shape.

A number of encryption communication products including quantum USB key, a protecting device for mobile payment, have been put to the market.

In one or two years, China is likely to issue national standards for quantum key distribution equipment, according to sources close to the trunk line project.

JIUQUAN, Oct. 9 (Xinhua) -- China launched Venezuela's remote sensing satellite, VRSS-2, into a preset orbit from the Jiuquan Satellite Launch Center in northwest China's Gobi desert at 12:13 on Monday.

The VRSS-2 was the third satellite jointly launched by China and Venezuela, and also the later's second remote sensing satellite. It will be primarily used by Venezuela for land resources inspection, environmental protection, disaster monitoring and management, crop yield estimation and city planning.

The satellite was launched by a Chinese Long March-2D carrier rocket which was designed by Shanghai Academy of Spaceflight Technology.

This was the 252nd flight mission for the Long March rocket family.

In 2008, China launched Venezuela's first satellite -- the Venesat-1, or "Simon Bolivar" -- which carried communications facilities.

In 2012, Venezuela's first remote sensing satellite, the VRSS-1, was launched into space from China.

INCHEON, South Korea, Sept. 24 (Xinhua) -- Japanese swimmer Kosuke Hagino and Chinese teenager Shen Duo clinched their fourth gold medal of the Asian Games respectively on Wednesday while two more doping cases were reported.

The 20-year-old Hagino clocked a winning time of 4 minutes 7.75 seconds in the men's 400m individual medley final, his specality event, adding to his collection of the 200m freestyle, 200m medley and 4x200m relay titles.P "I didn't feel right in the breaststroke. It was a different feeling than usual. But I went hard in the last 50m," said Hagino.

Hagino, who had vowed to win six gold medals in Incheon, will race in the 200m backstroke Thursday. "It will be a fight against the Chinese swimmers, but I'll swim a race that is true to myself," he said.

But it was the Chinese who emerged the biggest winners in the pool Wednesday as they won four of the seven events contested on Day Four - three women's individual events and the men's 4x100m freestyle relay.

Olympic champion Sun Yang swam the third leg for China as they outpaced Japan to win the 4x100m relay with an Asian record time of 3:13.47.

The Chinese foursome of Yu Hexin, Lin Yongqing, Sun Yang and Ning Zetao were in second place behind Japan during the first half of the race, but as soon as Sun dived into the water China quickly took over the lead and finished first place. Japan took the silver and the host nation, with Park Tae-hwan in the line-up, had to settle for the bronze.

"I am not good at charging, so the coaches let me swim the third leg," Sun explained afterwards.

Shen Duo, who grabbed six golds in last month's Youth Olympics in Nanjing, matched Hagino by winning the women's 200m freestyle to boost her haul of gold medals to four as well. Earlier, the 17-year-old grabbed golds in 100m freestyle, 100m breaststroke, 4x200m freestyle relay.

"I am very satisfied with today's result. I tried to do my best in the race, but the best thing about today is that I was able to get a medal alongside my teammate, (bronze medalist) Tang Yi," said Shen.

Shen's teammate Fu Yuanhui followed suit when she surged to victory in the women's 100m backstroke in 59.95 seconds, and Olympic champion Jiao Liuyang successfully retained her 200m butterfly crown in 2:07.56.

"My performance was just moderate and was two seconds slower than my best time, basically I am not very satisfied," said Jiao.

Singapore also had plenty to celebr. [url=http://www.wholesalecheapjerseysmlb.com/]Wholesale Cheap Jerseys[/url]   [url=http://www.wholesalecheapjerseyscollege.com/]Wholesale Throwback Jerseys[/url]   [url=http://www.soccerchinajerseyscheap.com/]Jerseys Free Shipping[/url]   [url=http://www.nhlchinajerseyscheap.com/]Adidas NHL Jerseys Cheap[/url]   [url=http://www.mlbchinajerseyscheap.com/]Baseball Jerseys Wholesale[/url]   [url=http://www.hockeynhljerseyscheap.com/]Hockey Jerseys Cheap[/url]   [url=http://www.footballnfljerseyscheap.com/]Football Jerseys Wholesale[/url]   [url=http://www.footballnflcheapjerseys.com/]Football Jerseys Wholesale[/url]   [url=http://www.collegejerseyscheap.com/]College Hockey Jerseys Wholesale[/url]   [url=http://www.chinasoccerjerseyscheap.com/]Replica Jerseys China[/url]
