This is an exceptional piece above.
What interested me was:
If the Chinese team is successful, other groups should find it easier to get funding for quantum satellites, says Zeilinger. The United States has a relatively low profile when it comes to this particular space race, but Zeilinger suggests that it could be doing more work on the topic that is classified.
Zeilinger is the top scientist in the field of quantum communications.
He must have some reason to suggest that US is working on a classified quantum communication project!

China successfully launched the world's first quantum satellite from the Jiuquan Satellite Launch Center in northwestern Gobi Desert at 1:40 a.m. on Tuesday.
In a cloud of thick smoke, the satellite, Quantum Experiments at Space Scale (QUESS), roared into the dark sky on top of a Long March-2D rocket.
The 600-plus-kilogram satellite will circle the Earth once every 90 minutes after it enters a sun-synchronous orbit at an altitude of 500 kilometers.
It is nicknamed "Micius," after a fifth century B.C. Chinese philosopher and scientist who has been credited as the first one in human history conducting optical experiments.
In its two-year mission, QUESS is designed to establish "hack-proof" quantum communications by transmitting uncrackable keys from space to the ground, and provide insights into the strangest phenomenon in quantum physics -- quantum entanglement.
Quantum communication boasts ultra-high security as a quantum photon can neither be separated nor duplicated. It is hence impossible to wiretap, intercept or crack the information transmitted through it.

Chinese scientist, the Chinese Academy of Sciences (CAS) announced Monday. (Xinhua/Jin Liwang)
With the help of the new satellite, scientists will be able to test quantum key distribution between the satellite and ground stations, and conduct secure quantum communications between Beijing and Xinjiang's Urumqi.
QUESS, as planned, will also beam entangled photons to two earth stations, 1,200 kilometers apart, in a move to test quantum entanglement over a greater distance, as well as test quantum teleportation between a ground station in Ali, Tibet, and itself.
"The newly-launched satellite marks a transition in China's role -- from a follower in classic information technology (IT) development to one of the leaders guiding future IT achievements," said Pan Jianwei, chief scientist of QUESS project with the Chinese Academy of Sciences (CAS).
The scientists now are expecting quantum communications to fundamentally change human development in the next two or three decades, as there are enormous prospects for applying the new generation of communication in fields like defense, military and finance.
SPOOKY & ENTANGLED
Quantum physics is the study of the basic building blocks of the world at a scale smaller than atoms. These tiny particles behave in a way that could overturn assumptions of how the world works.
One of the strange properties of quantum physics is that a tiny particle acts as if it's simultaneously in two locations -- a phenomenon known as "superposition." The noted interpretation is the thought experiment of Schrodinger's cat -- a scenario that presents a cat that may be simultaneously both alive and dead.
If that doesn't sound strange enough, quantum physics has another phenomenon which is so confounded that Albert Einstein described as "spooky action at a distance" in 1948.
Scientists found that when two entangled particles are separated, one particle can somehow affect the action of the far-off twin at a speed faster than light.
Scientists liken it to two pieces of paper that are distant from each other: if you write on one, the other immediately shows your writing.
In the quantum entanglement theory, this bizarre connection can happen even when the two particles are separated by the galaxy.
By harnessing quantum entanglement, the quantum key technology is used in quantum communications, ruling out the possibility of wiretapping and perfectly securing the communication.
A quantum key is formed by a string of random numbers generated between two communicating users to encode information. Once intercepted or measured, the quantum state of the key will change, and the information being intercepted will self-destruct.
According to Pan, scientists also plan to test quantum key distribution between QUESS and ground stations in Austria. Italy, Germany and Canada, as they have expressed willingness to cooperate with China in future development of quantum satellite constellations, said Pan.
LIFE CHANGING
With the development of quantum technology, quantum mechanics will change our lives in many ways. In addition to quantum communications, there are quantum computers that have also drawn attentions from scientists and governments worldwide.
Quantum computing could dwarf the processing power of today's supercomputers.
In normal silicon computer chips, data is rendered in one of two states: 0 or 1. However, in quantum computers, data could exist in both states simultaneously, holding exponentially more information.
One analogy to explain the concept of quantum computing is that it is like being able to read all the books in a library at the same time, whereas conventional computing is like having to read them one after another.
Scientists say that a quantum computer will take just 0.01 second to deal with a problem that costs Tianhe-2, one of the most powerful supercomputers in the world, 100 years to solve.
Many, however, is viewing this superpower as a threat: if large-scale quantum computers are ever built, they will be able to crack all existing information encryption systems, creating an enormous security headache one day.
Therefore, quantum communications will be needed to act like a "shield," protecting information from the "spear" of quantum computers, offering the new generation of cryptography that can be neither wiretapped nor decoded.
GOING GLOBAL?
With the launch of QUESS, Chinese scientists now are having their eyes on a ground-to-satellite quantum communication system, which will enable global scale quantum communications.
In past experiments, quantum communications could only be achieved in a short range, as quantum information, in principle, could travel no more than 500 kilometers through optical fibers on the land due to the loss of photons in transmission, Pan explained.
Since photons carrying information barely get scattered or absorbed when travelling through space and Earth's atmosphere, said Pan, transmitting photons between the satellite and ground stations will greatly broaden quantum communications'reach.
However, in quantum communications, an accurate transmission of photons between the "server" and the "receiver" is never easy to make, as the optic axis of the satellite must point precisely toward those of the telescopes in ground stations, said Zhu Zhencai, QUESS chief designer.
It requires an alignment system of the quantum satellite that is 10 times as accurate as that of an ordinary one and the detector on the ground can only catch one in every one million entangled photons fired, the scientist added.
What makes it much harder is that, at a speed of eight kilometers per second, the satellite flying over the earth could be continuously tracked by the ground station for merely a few minutes, scientists say.
"It will be like tossing a coin from a plane at 100,000 meters above the sea level exactly into the slot of a rotating piggy bank," said Wang Jianyu, QUESS project's chief commander.
Given the high sensitivity of QUESS, people could observe a match being lit on the moon from the Earth, Wang added.
After years of experimenting, Chinese scientists developed the world' s first-ever quantum satellite without any available reference to previous projects. Now they are waiting to see QUESS's performance in operation.
According to Pan, his team has planned to initiate new projects involving research on quantum control and light transmission in space station, as well as tests on quantum communications between satellites, all-time quantum communications and the application of quantum key network.
"If China is going to send more quantum communication satellites into orbit, we can expect a global network of quantum communications to be set up around 2030," said Pan.

China launches the world's first quantum satellite on top of a Long March-2D rocket from the Jiuquan Satellite Launch Center in Jiuquan, northwest China's Gansu Province, Aug. 16, 2016. (Photo/Xinhua)
China's successful launch of the world's first quantum satellite was "very exciting" and can help conduct experiments that may lead to "much more secure" quantum communications, a U.S. quantum expert said.
"The event is indeed very exciting and does carry global importance because this would be the first such experiment," said Alexander Sergienko, a professor of electrical and computer engineering at the Boston University.
The satellite, Quantum Experiments at Space Scale (QUESS), lifted off from China's Jiuquan Satellite Launch Center at 1:40 a.m. Tuesday, local time.
Sergienko said the quantum communication race has been going on for the last 20 years since the initial demonstration of quantum key distribution link under Lake Geneva in 1995.
After that, metropolitan secure communication networks have been developed and demonstrated in Boston, Vienna, Beijing, and Tokyo, and many more examples of quantum metropolitan networks have been demonstrated in the last five years covering Canada, Italy, U.K. and Australia, he said.
"The race is now moving in the near space in order to cover longer distances between different metropolitan areas," he said.
"I know there were plans to develop multiple point-by-point multi-city quantum communication segments to cover the distance between Shanghai and Beijing. A successful implementation of the satellite project would allow covering it in one step."
Sergienko also predicted that quantum communication and cryptography will be first used to ensure the most important communication lines such as used by the government and by major business in their communication.
China said the 600-plus-kilogram QUESS, nicknamed "Micius," is expected to circle the Earth once every 90 minutes after it enters a sun-synchronous orbit at an altitude of 500 kilometers.
In its two-year mission, QUESS is designed to establish "hack-proof" quantum communications by transmitting uncrackable keys from space to the ground, and provide insights into the strangest phenomenon in quantum physics -- quantum entanglement.

Do you think US has a secret Manhattan type project for quantum computing and networks?
US don't have money. They are busy spending money on super carrier and reopen production line of sea wolf class SSN and F-22 stealth fighter. US is falling into a trap exactly setup by us
Sourgrape spotted. Some loser want to make up some fantasy and claim some unknown project. US is one of the King of bragging. Anything they have, they would say it out. If no, means no.

It is not me, but Anton Zeilinger claiming that US has classified stuff. It never even occurred to me once before.
He is the leading scientist in this area. Pan Jianwei, and Lu Chaoyang both worked as students under him.

'Micius' to create $7.5b quantum communication market
China Daily, August 16, 2016
China launches the world's first quantum satellite on top of a Long March-2D rocket from the Jiuquan Satellite Launch Center in Jiuquan, Northwest China's Gansu province, Aug 16, 2016.[Photo/Xinhua]
China successfully launched the world's first quantum satellite "Micius", which is named after the ancient Chinese philosopher and scientist, from the Jiuquan Satellite Launch Center in northwestern Gobi Desert in the early hours of today.
Compared with traditional communication which faces bottlenecks or downside pressure, quantum communications is expected to be widely used in government, energy, finance, broadcasting and TV sectors and create a market worth over 50 billion yuan ($7.54 billion) in the next five years, the National Business Daily reports.
It marks a breakthrough in the development of quantum communications, communication expert Zhang Peng told the newspaper, adding that capital investment is now focusing more on satellite than internet. However, it will need more time to put the network into real use, Zhang said.
"If China is going to send more quantum communication satellites into orbit, we can expect a global network of quantum communications to be set up around 2030," Pan Jianwei, chief scientist of satellite project with the Chinese Academy of Sciences, told the Xinhua News Agency.
Though it still on the start-up phase, several securities companies issued reports, saying quantum communications will enter the harvest time. "Based on the characters of confidentiality and security, in the future, it will be widely used in military, government and energy."
TF Securities said over the next three years equipment and devices of military market is expected to be valued at 30 billion yuan, plus the civilian market, the market value of energy, finance, broadcasting and TV sectors will exceed 50 billion yuan over the five years.
So far more than 10 listed companies are involved in quantum communications, such as Kehua Tech, Sanlux Co Ltd, Zhejiang Orient Holdings Co Ltd, Kaile Science and Technology Co Ltd and Digital China Information Service Company Ltd.
Zhejiang Orient has closed higher for three consecutive trading days as its shareholding company invested in quantum communication enterprises, Zhejiang Shenzhen Quantum Technology Co Ltd and QuantumCTek Co Ltd.
