Quantum Factoring Algorithm Realized
Prof. PAN Jianwei, and his colleagues YANG Tao and LU Chaoyang at the University of Science and Technology of China, have for the first time in the world realized Shor's quantum factoring algorithm using photonic qubits. The research finding was published in Physics Review Letters on December 19, 2007.
The realization of Shor's quantum factoring algorithm on photonic qubits has long been an international puzzle. To compile a Shor's algorithm with quantum properties, researchers choose the simplest instance of this algorithm, and exploit a simplified linear optical network to coherently implement the quantum circuits of the modular exponential execution and semiclassical quantum Fourier transformation. Thanks to their painstaking efforts, and collaboration with researchers from Oxford University, genuine multiparticle entanglement is observed during this computation, which well supports its quantum nature. This experiment represents an essential step toward full realization of Shor's algorithm and scalable linear optics quantum computation.
Proprietary High Speed Locomotives
China’s proprietary high speed locomotives （CRH2-300）able to run 300km an hour have been rolled off on December 22, 2007. Equipped with an array of the state-of-the-art technologies, including aluminum alloy body with a reduced weight, high speed turntable, high speed pantograph, and optic-fiber based integrated control system, the locomotive weighs 7 tons, reaching an internationally advanced level in the context of energy efficiency and environmental protection.
The train compartment is seats only. The wide and streamlined exterior allows excellent air dynamics. The compartment is designed with numerous comfortables, including advanced ventilation system, multimedia audio and video system, vacuum toilet, personalized catering service, and special toilet for the disables. The entire train is also equipped with a range of advanced devices for a comfortable and smooth run at a high speed.
The high speed train will be soon put into bulk production. The first trains will be delivered in March 2008 for trial operations between Beijing and Tianjin, before coming into the official operation during the Beijing Olympic Game in 2008.
Proprietary Direct Write Lithography System
On December 25, 2007, China’s first proprietary direct write lithography system rolled off in Hefei, indicating that China has broken up the monopoly of imported direct write lithography system at submicrometer level. In the picture, a researcher is displaying a finished product rolled out from the new system.
New Respiratory Tract Virus Discovered
A clinical research center, jointly established by Zhejiang Wenling No. 1 People’s Hospital and a key biochips lab under Chinese Academy of Military Medical Sciences, has screened out a new respiratory tract virus (CLFF) from 278 infants’ acute respiratory tract infection samples. Its sequence results have bee archived on December 4, 2007 in Genbank.
Researchers say the finding makes another discovery, since they captured human bocavirus on July 2006 under the financing of National Natural Science Foundation. The research team is able to work out the accurate results of the virus within one hour.
Human Bird Flu Vaccine Phase II Succeeds
China’s human bird flu vaccine team announced on December 24, 2007 that Phase II clinical trials of human bird flu vaccine, jointly developed by Beijing Kexing Bioproducts and China CDC, has confirmed the safety of the vaccine in humans.
The results unveiled on December 22, 2007 shows that all 3 separate dosages of vaccines can induce human body to produce antibody to the viruses. Of them, the 18mg and 15mg dosages have produced all three indicators (positive antibody, positive antibody conversion rate, and GMT) up to the internationally accepted standard, indicating the fine immunity in humans. No serious side effects have been seen in people who are vaccinated.
Exercise Able Robot
A research team at Harbin Engineering University has recently developed an intelligent robot able to do exercise. With a height of 31cm, and weight 1.6 kg, the ‘small potato’ is able to perform a range of actions, including stretching, kneeling down, and turning. The ‘small potato’ has 16 motors for energy, and 16 free degree turntable structures, with a control board on the back. It receives command via a blue tooth device in which commands are pre saved for dancing and doing exercise.
The robot is able to do the popular “broadcast exercise”, a set of stretch actions helping people to relax. It can do the exercise in a gradual manner, allowing every detail to be shown in action. As a good entertaining partner, it is also a helper for diffusing scientific knowledge. Unfortunately, it cannot leap, as it simply does not have sufficient moment.
GM Pig Conceived
On December 22, 2006, three pigs cloned with green fluorescent protein (GFP) were born at the Northeast Agriculture University, the fourth of its kind in the world following the United States, the Republic of Korea, and Japan. The three piglets were born in a natural manner, with an initial weight at 1270g, 1130, and 1230g respectively. Thanks to their cloned GFP traits, their mouth, foot, and tongue will show green fluorescent light under the ultraviolet illumination.
Up to date, the three cloned female pigs have grown to expected weight, and got conceived after coupling with male pigs. They are expected to deliver their babies in January 2008. Researchers are eager to know if their babies carry the same GFP traits, and will select the one having the GFP traits for further coupling.
Power Plant Capture Carbon Dioxide
China’s first carbon dioxide capture demonstration project for coal burning power plant was kicked off on December 26, 2007 at Huaneng Beijing Power Plant. Scheduled to be put into operation in 2008, the project is designed with a recovery of carbon dioxide above 85%, or 3000 tons of carbon dioxide a year. After separation and purification, the recovered carbon dioxide will reach a purity as high as 99.5%, sufficient for applications in food industry. After its completion, Huaneng Beijing Power Plant will become China’s first coal burning power plant of environment friendly functions, including desulphurization, denitration, and carbon dioxide capture.
At the same time, a project to upgrade 4 boilers with advanced denitration technology in the same plant was completed on December 26, 2007. The upgrading will reduce the emission of nitrogen oxides from 400mg/m3 to 50mg/m3, reaching an internationally advanced level. Calculating on an annual capacity of 6000 hours, the project is able to reduce the emission of nitrogen oxides by 7000 tons a year, which will effectively improve the quality of atmospheric environment in Beijing, creating a fine environment for hosting the Beijing Olympic Game in 2008.
