China Launched the World’s First Quantum Satellite

China’s Quantum Satellite Experiments: Strategic And Military Implications – Analysis

While China’s quantum science satellite (QSS) project is part of the Strategic Priority Programme on Space Science, the country’s first space exploration programme intended purely for scientific research, its experiments have significant military implications.

By Michael Raska*

On August 16, 2016 China launched the world’s first quantum communications experiment satellite into orbit from the Jiuquan Satellite Launch Centre in the Gobi Desert. The small satellite, recently named Micius after an ancient Chinese philosopher, is tasked to establish a hack-proof communication line – a quantum key distribution network, while performing a series of quantum entanglement experiments in space for the first time.

The quantum science satellite (QSS) programme is the third mission of the 2011 Strategic Priority Programme on Space Science that includes a series of satellite launches between 2015 and 2030 to explore black holes, dark matter, and cosmic background radiation. Research on quantum technology is also a key priority, including in the 13th Five-Year Plan, China’s latest economic blueprint for research and development released in March 2016. The QSS is sponsored and managed by the China Academy of Sciences (CAS), and led by chief scientist Pan Jianwei. Its mission payload was developed jointly by the CAS’s Shanghai Institute of Technical Physics (SITP) and the University of Science and Technology of China (USTC).

“Quantum Internet” and Communication Experiments
While the QSS will advance research on “quantum internet” – i.e. secure communications and a distributed computational power that greatly exceeds that of the classical Internet, Micius’ experiments will also advance quantum cryptography, communications systems, and cyber capabilities that the China’s military (PLA) requires for its sensors and future strike systems.

Micius’ experiments are designed to advance communication between space and Earth using quantum information technology, which relies on transmitting photons, or tiny particles of light. In particular, rather than using radio waves by traditional communications satellites, a quantum communication uses a crystal that produces a pair of entangled photons whose properties can be manipulated to perform cryptographic tasks.

For example, one can encode cryptographic keys in the discrete properties of a pulse of light, such as its polarisation state, or the continuous aspects of an electromagnetic wave, such as the intensity and phase of the wave’s electric field. In doing so, the complex quantum properties cannot be measured or reverse engineered without destroying the particle’s original quantum states, so the embedded cryptographic keys, in theory, cannot be copied, stolen, or manipulated.

In this context, Micius will conduct three rounds of experiments in the next two years. The first phase includes testing a secure transmission of data to targeted areas on Earth, including three ground receiving stations located at Miyun (Beijing), Sanya (Hainan), and Kashgar (Xinjiang), and processed by the National Space Science Centre (NSSC) of the China Academy of Sciences (CAS) in Beijing. These ground stations will then beam the photon chains with cryptographic keys back to Micius, which the satellite will then relay to other ground stations to decode the message.

More Ambitious Goal
The second and third round of experiments are more ambitious, focusing on complex challenges related to particle entanglement – i.e. if two quantum particles are entangled, a change of quantum state of one particle triggers a counter-change on the other, even for systems that are too far apart to physically interact. Particle entanglement is theoretically possible across any distance, however, the fragile state of entanglement currently limits that distance to around 100 kilometres. With the QSS, Chinese researchers hope to increase that distance to more than 1,000 km.

If this phase succeeds, the QSS third round of experiments will attempt to implement the idea of teleportation of quantum information, a phenomenon described by Albert Einstein as “a spooky action at a distance”. Scientists will generate a pair of entangled photons at a ground station; one photon will be transmitted to Micius, while the other will remain on the ground.

Altering the quantum state of the particle on the ground – such as a clockwise spin – may simultaneously trigger a counter-clockwise spin in space. While theoretically possible, such ‘teleportation’ carries significant challenges, including compensating for atmospheric turbulence and movement on the ground. It also requires advanced precision technologies to synchronise both ends.

Strategic and Military Implications
China plans a network of quantum satellites by 2030, which will augment a ground-based quantum computer network, which will likely be extended from the currently operational 2,000 km link between Beijing and Shanghai. If successful, China’s quantum communication network will serve as a dual-use strategic asset that may advance PLA’s capacity for power projection through a constellation of space-based intelligence, surveillance, and reconnaissance platforms, tactical warning and attack assessment; command, control, and communications; navigation and positioning, and environmental monitoring.

In the PLA terms, establishing “space dominance” (“zhi tian quan”) is an essential enabler for “information dominance” (zhi xinxi quan) – a key prerequisite for allowing the PLA to seize air and naval superiority in contested areas. To this end, the PLA and civilian-defence R&D community have been developing multiple types of satellites to enhance PLA’s military effectiveness: electro-optical (EO), synthetic aperture radar (SAR), electronic intelligence (ELINT), Beidou navigation satellites, microsatellites, and also quantum communication satellites. In the PLA’s strategic thought, as reflected in the 2013 Science of Military Strategy, the ability to enter, control, and exploit space serves not only as a force enhancement, but also as a deterrent factor.

Specifically, integrated space-based electronic reconnaissance and secure communications enables PLA’s long-range precision strike capabilities, including its anti-ship ballistic missiles such as DF-21D. An SAR satellite uses a microwave transmission to create an image of maritime and ground-based targets in real time and in all weather conditions. Quantum communication satellites could be then used as data relay satellites to securely transmit targeting data to and from command centres, while evading cyber interceptions. These capabilities may in turn shape the direction and character of US carrier strike group operations at sea.

China, however, does not have a monopoly on quantum technologies. Both Russia and the US have large-scale cryptologic quantum computing development programmes, attempting to exploit the potential of quantum computing in future warfare. Military space operations together with quantum computing and cyber warfare will likely shape the contours of strategic competition as well as competitive strategies between great powers and their allies.

Big step for quantum teleportation won’t bring us any closer to Star Trek. Here’s why
By Adrian Cho, Sep. 19, 2016 , 11:15 AM

Two teams have set new distance records for quantum teleportation: using the weirdness of quantum mechanics to instantly transfer the condition or “state” of one quantum particle to another one in a different location. One group used the trick to send the state of a quantum particle of light, or photon, 6.2 kilometers across Calgary, Canada, using an optical fiber, while the other teleported the states of photons over 14.7 kilometers across Shanghai, China.

Both advances, reported today in Nature Photonics, could eventually lead to an unhackable quantum internet. But what else is quantum teleportation good for? And will we ever be able to use it to zip painlessly to work on a frigid January morning?

Next Big Future: Quantum teleportation and communication across result fiber networks

Two independent teams have transferred quantum information over several kilometers of fiber optic networks.

Conceptually, one way of doing teleportation involves three participants: say, Alice, Bob and Charlie. In order for Alice and Bob to exchange cryptographic keys, they have to first establish the capacity for teleportation, with Charlie’s help.

First Alice sends a particle (A) to Charlie. Bob, meanwhile, creates a pair of entangled particles (B & C), sends B to Charlie and holds on to C. Charlie receives both A and B, and measures the particles in such a way that it’s impossible to tell which particle was sent by Alice and which by Bob. This so-called Bell state measurement results in the quantum state of particle A being transferred to particle C, which is with Bob.

In the first teleportation experiments performed in 1997, Alice, Bob and Charlie were on the same optical bench in the same laboratory. The distances involved were few tens of centimetres. If teleportation distance is defined as the distance between Charlie and Bob, then until recently the record was a mere 800 metres, because doing a Bell state measurement was difficult with photons that had travelled too far.

The record for sheer distance between Alice and Bob was set in 2012, when a group led by Anton Zeilinger at the University of Vienna achieved teleportation over 143 kilometres of free space between two of the Canary Islands. But there’s no obvious way to translate that feat into a practical quantum network that would work within a city, where free space is hard to come by and other interference would destroy delicate quantum states.

Now, Wolfgang Tittel at the University of Calgary in Alberta, Canada, and colleagues have upped the ante. They extended the distance between Charlie and Bob and teleported quantum states using part of Calgary’s fibre optic network that isn’t being used for regular communications.

​

“The distance between Charlie and Bob, that’s the distance that counts,” says Tittel. “We have shown that this works across a metropolitan fibre network, over 6.2 kilometres, as the crow flies.”

Jian-Wei Pan at the University of Science and Technology of China and colleagues achieved a comparable separation between Charlie and Bob when they teleported quantum states using the city of Hefei’s fibre optic network. Their setup was slightly different, though: it was Charlie in the middle who created the entangled pair of particles and sent one to Bob, instead of the other way around.

The current work is scalable with Quantum repeaters. This could allow communication across arbitrary distances

If a photon interacts with a member of an entangled photon pair via a so-called Bell-state measurement (BSM), its state is teleported over principally arbitrary distances onto the second member of the pair. Starting in 1997, this puzzling prediction of quantum mechanics has been demonstrated many times; however, with one very recent exception, only the photon that received the teleported state, if any, travelled far while the photons partaking in the BSM were always measured closely to where they were created. Here, using the Calgary fibre network, we report quantum teleportation from a telecommunication-wavelength photon, interacting with another telecommunication photon after both have travelled over several kilometres in bee-line, onto a photon at 795~nm wavelength. This improves the distance over which teleportation takes place from 818~m to 6.2~km. Our demonstration establishes an important requirement for quantum repeater-based communications and constitutes a milestone on the path to a global quantum Internet.

China-only science prize honours pathologist and experimental physicist
Research on non-invasive pregnancy tests and superconductors earns $1 million 'Chinese Nobels'.

David Cyranoski,19 September 2016

The first winners of a prize devoted exclusively to scientific discoveries made in China were announced on 19 September in Beijing.

The Future Forum, a non-profit organization established last year in Beijing, announced that pathologist Dennis Ming Yuk Lo of Chinese University of Hong Kong won the life science Future Science Prize for the discovery that DNA from a foetus can be extracted from the mother’s blood. The discovery led to the now-widely-used non-invasive tests to screen a pregnant woman’s blood to see if the foetus has disorders such as Down’s syndrome. Shenzhen-based BGI alone has carried out more than 1 million screens based on the finding.

Qi-Kun Xue of Tsinghua University in Beijing netted the physics prize for the experimental discovery of high-temperature superconductivity at the interfaces of materials1 and the quantized anomalous Hall effect2 — an unusual orderly motion of electrons in a conductor at low temperature. That line of work belongs in the fast-emerging field of topological insulators. Each prize is worth US$1 million.

China sets world record for scientific ocean coring
lXinhua, September 20, 2016

China has set a new world record for scientific ocean coring, successfully drilling 2,843.18 meters into a continental shelf in the Yellow Sea.

Shandong No. 3 Institute of Geology and Mineral Resources said Tuesday that the drilling operation had helped verify that there were oil and gas deposits in the stratum.

The institute developed and established a drilling platform for the project in March 2015 in the waters some 83 sea miles east of Lianyungang City in the eastern province of Shandong, where the water is about 30 meters deep.

The platform is capable of holding up in gales of up to 150 km per hour.

The project is sponsored by the China Geological Survey Bureau. The coring sample can assist research into the geology of continental shelf, an important belt linking continents with oceans.

Chinese scientists realize quantum teleportation within intercity network
(People's Daily Online) September 21, 2016

Recently, scientists from the University of Science and Technology of China accomplished the world’s first quantum teleportation between independent sources in the intercity communication network of Hefei, Anhui province, People’s Daily reported. Quantum teleportation is used to deliver quantum information, which is enciphered in photons, from one place to another.

This research result was published online by Nature Photonics on Sept. 19. The finding of a Canadian research team on quantum teleportation was also published in the same journal. Together, these two research projects demonstrate that it is feasible to conduct quantum teleportation within an intercity network. They have also laid a solid foundation for the construction of a more expansive quantum network in the future.

Zhang Qiang, a professor at the University of Science and Technology of China, explained that private quantum communication currently uses a quantum key to encrypt classified information. As the technology develops, the transmission of quantum information will be realized, and quantum teleportation - which depends on optical networks - will greatly enhance the security and strength of Internet connections.

China’s first robot boasting both security capabilities and intelligence skills, debuted at the 12th Chongqing Hi-Tech Fair on April 21.

Developed by the National Defense University, AnBot represents a series of breakthroughs in key technologies including low-cost autonomous navigation and intelligent video analysis, which will play an important role in enhancing the country's anti-terrorism and anti-riot measures.

AnBot's shape is similar to that of a Russian nesting doll. The robot is 1.49 meters in height, 78 kilograms in weight and 0.8 meters in diameter. Its maximum speed is 18 kilometers per hour, and its standard patrol speed is 1 kilometer per hour. It has sensors that mimic the human brain, eyes and ears. Capable of eight hours of continuous work, AnBot is able to patrol autonomously and protect against violence or unrest.

When people around AnBot face security threats, the robot’s control personnel can remotely deploy AnBot’s electrically charged riot control tool. Within AnBot’s patrol area, people can also call for help or press the SOS button on the robot’s body to notify police of a problem.

China National GeneBank, the country’s first national gene bank, was officially put into use on Thursday. The complex is expected to offer strong support to the development of the genetics industry.

Located in Shenzhen, Guangdong province, the billion-dollar CNGB covers an area of 47,500 square meters with a unique design like terraced fields and has saved more than 10 million bio-samples with a data storage capacity of 20 petabytes for phase I.

One petabyte is about 400 billion pages of word documents.

It is the world’s fourth national-level gene bank. The other three are in the US, Europe and Japan.

Wang Jian, president of Shenzhen-based genetic sequencing firm BGI, said: “The CNGB’s data will be open to society, providing strong support to the development of the genetics industry.”

China’s genetic sequencing market, one of the most important aspects of the industry, in 2016 has become the largest in the world with an annual growth rate of above 20 percent, according to research firm iResearch Consulting Group.

To further support the development of the industry, the National Development and Reform Commission in 2011 approved the establishment of CNGB and entrusted BGI-Research with its construction.

Mei Yonghong, former mayor of Jining in Shandong province who is now director of CNGB, said he believes the gene bank can link all elements of gene-related fields, from resources and scientific research to applications in different industries, such as precision medicine and agriculture.

At the opening ceremony, CNGB signed cooperation agreements with some international and local partners, such as Svalbard Global Seed Vault, German Cancer Research Center, Shenzhen Institute of Advanced Technology and Huawei Technologies, which provides data storage service for the bank.

Lyu Jiancheng, vice director of SIAT, said the CNGB will help them to write genes of 10 million phages (a kind of virus) so that they can make new reagents and develop new medicines.

The opening of the gene platform will also reduce costs in the genetic industry, thanks to home made equipment with high precision.

The world leading gene company Illumina has managed to practice individual genetic sequencing within the cost of below US$1,000 in 2014, but Mei Yonghong said the aim of CNGB is 1,000 yuan (US$152).

BGI’s new genetic sequencing equipment BGISEQ-500, which is expected to hit the market in October and the price is said to be one third of its counterparts.

CNGB owns 150 sets of the equipment now and the platform could satisfy the gene sequencing needs of 50,000 people.

Xu Xun, executive director of CNGB, disclosed the machine is completely manufactured in Shenzhen — an important reason for its low price, and more models of their genetic sequencing equipment will be released in November.

How to power up graphene implants without frying cells
New analysis finds way to safely conduct heat from graphene to biological tissues.

Jennifer Chu | MIT News Office
September 23, 2016

This computational illustration shows a graphene network structure below a layer of water.

In the future, our health may be monitored and maintained by tiny sensors and drug dispensers, deployed within the body and made from graphene — one of the strongest, lightest materials in the world. Graphene is composed of a single sheet of carbon atoms, linked together like razor-thin chicken wire, and its properties may be tuned in countless ways, making it a versatile material for tiny, next-generation implants.

But graphene is incredibly stiff, whereas biological tissue is soft. Because of this, any power applied to operate a graphene implant could precipitously heat up and fry surrounding cells.

Now, engineers from MIT and Tsinghua University in Beijing have precisely simulated how electrical power may generate heat between a single layer of graphene and a simple cell membrane. While direct contact between the two layers inevitably overheats and kills the cell, the researchers found they could prevent this effect with a very thin, in-between layer of water.

By tuning the thickness of this intermediate water layer, the researchers could carefully control the amount of heat transferred between graphene and biological tissue. They also identified the critical power to apply to the graphene layer, without frying the cell membrane. The results are published today in the journal Nature Communications.

Major breakthrough! Chinese doctor with baking soda, hungry dead cancer cells

2016-09-25 00:59:19 132 ℃

Introduction: he and his research team found a new therapy starve cancer cells, and published in the field of international biological and Medical Journal of eLife, the international famous scholars of tumor.

Cancer cells also need to 'eat' things to survive, deprived of its food, cancer cells will die." Professor Hu Xun of Zhejiang University cancer research that is in this seemingly simple principle, he and his research team found a new therapy starve cancer cells, and published in the field of international biological and Medical Journal of eLife, the international famous scholars of tumor.

After years of research, Hu Xun found that glucose cancer cells must eat something, they see the cancer will die glucose deprivation. But in fact, the lack of glucose supply, the tumor did not starve to death also continue to grow.

Professor Hu Xun revealed the mystery: there are a lot of lactic acid in tumor, lactic acid dissociation into lactic acid anion and hydrogen ion, as the two "helper" cancer cells, make its own according to "food" determines the number of how many "consumption".

Hu xun

Two "helper" synergy makes cancer cells in glucose content rarely, very economical use of glucose; enter "sleep" state in the absence of glucose; when the glucose supply restored growth state.

Therefore, if you want to effectively "starve to death" cancer cells, not only to deprive of glucose, but also to destroy the lactic acid anion and hydrogen ions synergistic effect. In the absence of glucose starvation or lack of the premise, as long as the removal of any one of the two factors,Cancer cells will die quickly.

The researchers used alkali such as sodium bicarbonate (sodium bicarbonate) to remove hydrogen ions within the tumor, the synergistic effect can destroy lactate and hydrogen ions, so as to effectively kill in glucose starvation or lack of tumor cells.

The rapid transformation of basic research results into tumor clinical treatment, so that more patients benefit is the key.

Since 2012, with 30 years of clinical experience in radiology the Second Affiliated Hospital of Zhejiang University School of Medicine Department of interventional radiology doctor Chao Minghe Hu Xun team hit it off, into the primary hepatocellular carcinoma model therapy study, and this method is named "targeting tumor lactate anions and hydrogen ions arterial chemoembolization, referred to as" TILA-TACE".

Ming Chao

Clinically, Chao Ming explained: "conventional arterial chemoembolization (cTACE) cut off the tumor 'food channel', and then we use sodium bicarbonate to remove hydrogen ion within the tumor, the tumor is equivalent to not only to 'eat' let it go to the gym, fast consumption, rapid" starve "."

It is inspired, clinical study results show: they were treated with cTACE 37 patients, 18 cases were effective; with TILA-TACE for the treatment of 40 cases of patients, 40 cases were effective.

And liver cancer treated with TILA-TACE in this clinical study.Are difficult to treat liver cancer.

And the international comprehensive report, the average objective effective rate of cTACE treatment was 35%. 35% to 100%, such a huge contrast, not only to the international counterparts in the acceptance of this article, very carefully, even the two professors have been suspected in carrying out this research.

"At present preliminary statistics, the patient's median survival, has more than three years and a half; follow-up still need large sample randomized controlled study, if confirmed effective, for liver cancer treatment, is indeed a leap." Two experts said.

@Bussard Ramjet We need formal translation of this great achievement in cancer therapy!

Life science is one area in which China will play an increaingly important role in the coming decade.

China’s version of GPS ‘is now just as accurate’
Viola Zhou
Developer of Beidou global positioning system says it can match performance of US rival
PUBLISHED : Monday, 26 September, 2016, 12:00am
UPDATED : Monday, 26 September, 2016, 12:00am

China’s Beidou navigation system is now accurate within centimetres and on par with the US Global Positioning System (GPS), said a scientist who has been developing the technology.

The system could even offer more precise positioning services than its US rival within China, but further support was needed to make GPS users switch to Beidou, navigational-systems expert Xu Ying said at a technology expo in Hong Kong on Sunday.

Beijing has been building the system to make its domestic users, including the military, less dependent on foreign technology. Most Chinese lighthouses, military facilities and fishing boats had been using it since an Asia-Pacific network was completed in 2012, officials said earlier.

China to launch world’s first ‘cold’ atomic clock in space ... and it’ll stay accurate for a billion years

For military users, Beidou provided improved security against interference and interception, Xu said. It is unclear how many users within the PLA have switched to Beidou.

Xu said about 70 per cent of the fishing boats in the South China Sea had been equipped with the system. They benefited from its unique communication function, which enabled terminals to send out messages along with their location information, she added.

“With Beidou, they can let families know they are safe,” Xu said. “They can also report to coastguards if something happens. It ensures the safety of South China Sea fishermen.”

Xu said some mapping and construction companies were using Beidou and GPS at the same time to prepare for a complete shift to the home-grown system.

In 2013, a Xinhua report said more than 90 per cent of industrial users who needed positioning accuracy within centimetres relied on GPS.

A major goal of Beidou was to protect those industries, such as irrigation and urban planning, against the risk of the US turning the GPS off, the report said.

With 23 satellites in orbit, the Beidou navigation system now covers China and some neighbouring countries. Beijing hopes to launch about 20 more satellites by 2020 for its global network.

China hopes to make Beidou a world-class navigation system that serves people all over the globe, according to an official document on Beidou released in June.

Beijing has persuaded a few Asian countries, including Laos and Pakistan, to adopt Beidou’s free civilian service. The government is in contact with other states under the “One Belt, One Road” infrastructure scheme to promote the system.

The Beidou team was also exploring applications in agriculture, disaster relief and even animal protection, Xu said.

The first robot exoskeleton in China, named AIDER, has been officially unveiled in Chengdu, Sichuan province, making China the fourth country in the world to develop the cutting-edge technology.

AIDER, which some compare to the fictional Ironman, was developed by the Center of Robotics at the University of Electronic Science and Technology of China. The technology took six years of hard work and technical innovation to master.

AIDER functions through the use of dozens of censors, which detect a user's physical intentions. The censors then send electronic signals to the control unit, prompting various components to work together to drive the joint parts and help the user move freely.

According to Lin Xichuan, one of the developers, this wearable exoskeleton robot combines human intelligence with physical strength. It is an important breakthrough for many people who require assistance with walking and rehabilitation. Compared with traditional rehabilitation equipment, AIDER enables patients to walk relatively freely. It also facilitates blood circulation to the legs and prevents muscle atrophy. It can even help patients recover their biological memories of walking.

Cheng Hong, executive director of the Center of Robotics, said that the robot exoskeleton can be used in military and sporting applications, as it can help users carry heavy objects. Using the robot exoskeleton, a single soldier can carry items as heavy as 90 kilograms.

At present, AIDER has begun low-volume production. Preliminary clinical trials have been conducted on a group of physically disabled people.
