Scientists Uncover New Way of retaining Quantum Memories Stored in Light
Wed, 09/30/2015 - 10:45am
Chinese scientists have uncovered a novel way of stopping light in a state that stores information encoded in photons, opening the door to applications in quantum information processing.
A team of Chinese physicists has developed a way to confine light. This is significant because the approach allows quantum memories stored within photons to be retained, opening the door to applications in quantum information processing. The results may herald the advent of a multitude of hybrid, optoelectronic devices relying on the use of quantum information stored in photons for processing information that can be used in communication networks or quantum computing.
These findings stem from a study by Nan Sun from Nanjing University of Posts & Telecommunications, China, and colleagues, which has just been published in EPJ D.
Indeed, stopping and storing light for a duration ranging from a few seconds to a few minutes is key for quantum information processing. Unfortunately, certain media induce a loss of coherence of the light, due to effects of the surroundings, which, in turn, affects the integrity of the quantum information stored in photons. This new study focuses on understanding the propagation properties of the electromagnetic wave associated with light to learn how best to stop it.
Previous attempts at stopping light by Georg Heinze and colleagues from Technische Universität Darmstadt, Germany, showed it was possible to stop light for an entire minute. They dramatically slowed down light’s progression via interaction within its propagation medium.
In contrast, the authors here rely on electric and magnetic polarization to predict the conditions under which light could be confined. The authors’ theoretical approach is based on controlling the speed at which the light’s energy flows in order to stop it. At the same time, they also predict what it takes in terms of energy density to reach a stage where the electromagnetic waves constitutive of light can be stored, particularly in a medium in which waves travel at different speeds or are absorbed

Software prototype unveiled to study the Earth
By He Dan ( China Daily ) Updated: 2015-09-28 07:46:55
The prototype of a supercomputer system to explore the Earth and provide possible solutions for reducing environmental risks, including air pollution and global warming, was unveiled in Beijing on Wednesday.
The prototype of the earth system numerical simulator was jointly launched by the Chinese Academy of Sciences, China's top science think-tank, and Sugon Information Industry Co Ltd at the Zhongguancun Science Park or Z-Park in the capital's Haidian district.
The Institute of Atmospheric Physics under the CAS has developed its first version of the software that can be used on the prototype.
The prototype will be used to study the Earth in terms of interplay between different aspects like the lithosphere, hydrosphere, biosphere and the atmosphere, said Zeng Qingcun, a scientist with expertise in atmospheric dynamics.
The computer system will be able to process mass data and information, which is the precondition for scientists to discover rules in the function of the Earth system and the impact of human activity on the planet, he said.
The research will seek to establish an early-warning mechanism for possible natural disasters and environmental risks, said Zeng.
China's progress in Earth sciences can help political decision-making, especially in terms of environmental diplomacy, he said.
"Some neighboring countries accused China of causing sandstorm in their homelands, which is ridiculous as China is an 'import' instead of 'export' country of sandstorm, but we need solid statistics to dismiss such accusations," he said.
Ding Yihui, an academic from the Chinese Academy of Engineering, regarded the supercomputer system as a "remarkable" achievement in fundamental science.
"It can simulate the impact of cosmic rays and solar wind on the Earth, which can enable scientists to anticipate the climate change in at least three decades and such anticipation is vital to improving the environment," he said.
Zhu Jiang, head of the Institute of Atmospheric Physics under the CAS, told China Daily that the program can contribute to the municipal government's efforts to build the capital city into the national hub of technological innovation center. Zhu revealed that his institute, the National Development and Reform Commission and the Beijing municipal government will cooperate to establish an assembly base for large scientific devices in Huairou district.

China will build a supercomputer simulation of the Earth system
Posted on September 25, 2015 by nancy in China Society
In a two-storey high, shaped like a Rubik’s cube, buzzing super computer, and Chinese scientists to calculate the Earth’s future climate change.
From the development of a cloud, to Earth hundreds, thousands, even tens of thousands of years after climate change, scientists wanted to be called “numerical Earth simulators” calculated.
23rd, Institute of atmospheric physics, Chinese Academy of Sciences and the dawning information industry (Beijing) co computer network information center, Chinese Academy of Sciences Institute of computing technology, Chinese Academy of Sciences jointly issued a “numerical Earth simulators” research and prototype systems. This high performance computer system based on CAs Earth system model version 1.0 completion of filling the gaps in China’s Earth system model data platform.
This is located in Beijing’s Zhongguancun software Park in the dark blue cube while about 5.4 meters long, China’s future “numerical Earth simulators” a smaller version of the that contains the high performance computer hardware, application of numerical simulation of the Earth software, parallel software support, and many other parts of the Visual system, can meet the needs for simulation of the Earth System. Scientists can use the system in Earth system model development, short-term climate prediction, haze governance results.
Chinese Academy of engineering, the national climate Center of China Meteorological Administration experts said Ding Hui, China this is the significant progress of the study on the Earth Simulator is very amazing groundwork, will provide a solid foundation for integration of weather and climate.
The Earth’s atmosphere, hydrosphere, biosphere and many layers to a coupling system a very scientific and reasonable. “Outside of the Earth system also has an impact on us, the earth itself can be simulated and outer space, cosmic rays, solar wind and other factors is very strong, can help us study is at least 30 years of environmental changes, changes in PM2.5, for cutting greenhouse gases and to improve the environment will play an important role. “Ding Hui said.

Forget driverless cars, China just put a massive self-driving bus on the road
By Trevor Mogg — October 1, 2015
Google may have little pod-like driverless cars tootling about the streets of California, but a Chinese company recently sent a massive, self-driving bus packed with passengers on a 20-mile ride through the city of Zhengzhou.
Yutong, the firm that helped build the vehicle, said that on its maiden journey earlier this month the specially adapted bus “successfully completed a series of highly complex driving acts,” such as automatically changing lanes, overtaking, and responding to lights.
Hitting a top speed of 42 mph and reaching its destination without so much as a scratch, the journey apparently marked the world’s first successful trial of a self-driving bus.
Yutong has spent the last three years working with the Chinese Academy of Engineering and driverless-car experts to create tech for the bus that includes two cameras, four laser radars, and an integrated navigation system.
The company says the bus and its self-driving technology require further development and testing before a proper rollout can be considered.
A video posted this week by Russia Today shows the vehicle making its way along a highway. While the passengers may look a little unsure about the idea of a self-driving bus taking them around town, the “driver,” reclining in his seat with his hands behind his head, looks like he’s throughly enjoying the experience.
Perhaps it hasn’t dawned on him yet that he might soon be out of a job.
