World's first Quantum communication satellite to be launched in China against hackers

China is poised to become the first country to send encoded information from space that cannot be hacked. Scientists are making final adjustments to China’s first quantum communication satellite. The project chief describes it as a revolution in communications.

China will launch its first experimental quantum communication satellite in July, according to the Chinese Academy of Sciences.

China is poised to become the first country to send encoded information from space that cannot be hacked. Scientists are making final adjustments to China’s first quantum communication satellite. The project chief describes it as a revolution in communications.

A quantum photon cannot be separated or duplicated, which means if someone tried to decode information, the encryption would change, and the receiver would know that his letter was opened by someone.

Scientists hope the new technology will protect China from future cyber issues. In 2015, cases involving information technology in China rose by more than 120 percent, according to survey by a non-profit cybersecurity institution. China plans to use its quantum satellite system to cover the planet by 2030.

On the ground, China is also building its own quantum information sharing network for use in national defense and security. At some point, China plans to connect the ground network to the quantum satellite system.

It has taken five years for Chinese scientists to develop and manufacture the first quantum satellite. In June, it will be transported to the Jiuquan Satellite Launch Center in southwest China for final preparation and launch in July., 2016

Physicists celebrate evidence of particle 

To cheers and standing ovations, scientists at the world's biggest atom smasher have claimed the discovery of a new subatomic particle.

They say it's "consistent" with the long-sought Higgs boson that helps explain what gives all matter in the universe size and shape.

"We have now found the missing cornerstone of particle physics," Rolf Heuer, director of the European Centre for Nuclear Research (CERN), told scientists.

He said the newly discovered subatomic particle is a boson, but he stopped just shy of claiming outright that it is the Higgs boson itself - an extremely fine distinction.

"As a layman, I think we did it," he told the elated crowd.

"We have a discovery. We have observed a new particle that is consistent with a Higgs boson."

The Higgs boson, which until now has been a theoretical particle, is seen as the key to understanding why matter has mass, which combines with gravity to give an object weight.

The idea is much like gravity and Isaac Newton's discovery of it - gravity was there all the time before Newton explained it.

But now scientists have seen something very much like the Higgs boson and can put that knowledge to further use.

CERN's atom smasher, the $A10 billion Large Hadron Collider on the Swiss-French border, has been creating high-energy collisions of protons to investigate dark matter, antimatter and the creation of the universe, which many theorise occurred in a massive explosion known as the Big Bang.

Two independent teams at CERN said on Wednesday they had both "observed" a new subatomic particle - a boson.

Heuer called it "most probably a Higgs boson but we have to find out what kind of Higgs boson it is".

Asked whether the find is a discovery, Heuer answered, "As a layman, I think we have it. But as a scientist, I have to say, '"What do we have?'"

The leaders of the two CERN teams - Joe Incandela, head of CMS with 2100 scientists, and Fabiola Gianotti, head of ATLAS with 3000 scientists - each presented in complicated scientific terms what was essentially extremely strong evidence of a new particle.

Incandela said it was too soon to say definitively whether it is the "standard model" Higgs that Scottish physicist Peter Higgs and others predicted in the 1960s - part of a standard model theory of physics involving an energy field where particles interact with a key particle, the Higgs boson.

"The" Higgs or "a" Higgs - that was the question on Wednesday.

"It is consistent with a Higgs boson as is needed for the standard model," Heuer said.

"We can only call it a Higgs boson - not the Higgs boson."

Higgs, who was invited to be in the audience, said he also could not yet say if it was part of the standard model.

But he told the audience the discovery appears to be very close to what he predicted.

"It is an incredible thing that it has happened in my lifetime," he said, calling it a huge achievement for the proton-smashing collider built in a 27-kilometre underground tunnel.

The stunning work elicited standing ovations and frequent applause at a packed auditorium in CERN as Gianotti and Incandela each took their turn.

Incandela called it "a Higgs-like particle" and said "we know it must be a boson and it's the heaviest boson ever found".

Quantum Computing? Quantum Bar Magnets in a Transparent Salt

ScienceDaily (June 15, 2012) — Scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices.

The international team of researchers led from the Laboratory for Quantum Magnetism (LQM) in Switzerland and the London Centre for Nanotechnology (LCN), found that the material, a transparent salt, did not suffer from the usual complications of other real magnets, and exploited the fact that its quantum spins -- which are like tiny atomic magnets -- interact according to the rules of large bar magnets. The study is published in Science.

Anybody who has played with toy bar magnets at school will remember that opposite poles attract, lining up parallel to each other when they are placed end to end, and anti-parallel when placed adjacent to each other. As conventional bar magnets are simply too large to reveal any quantum mechanical nature, and most materials are too complex for the spins to interact like true bar magnets, the transparent salt is the perfect material to see what's going on at the quantum level for a dense collection of tiny bar magnets.

The team were able to image all the spins in the special salt, finding that the spins are parallel within pairs of layers, while for adjacent layer pairs, they are antiparallel, as large bar magnets placed adjacent to each other would be. The spin arrangement is called "antiferromagnetic." In contrast, for ferromagnets such as iron, all spins are parallel.

By warming the material to only 0.4 degrees Celsius above the absolute "zero" of temperature where all classical (non-quantum) motion ceases, the team found that the spins lose their order and point in random directions, as iron does when it loses its ferromagnetism when heated to 870 Celsius, much higher than room temperature because of the strong and complex interactions between electron spins in this very common solid.

The team also found that they could achieve the same loss of order by turning on quantum mechanics with an electromagnet containing the salt. Thus, physicists now have a new toy, a collection of tiny bar magnets, which naturally assume an antiferromagnetic configuration and for which they can dial in quantum mechanics at will.

"Understanding and manipulating magnetic properties of more traditional materials such as iron have of course long been key to many familiar technologies, from electric motors to hard drives in digital computers," said Professor Gabriel Aeppli, UCL Director of the LCN.

"While this may seem esoteric, there are deep connections between what has been achieved here and new types of computers, which also rely on the ability to tune quantum mechanics to solve hard problems, like pattern recognition in images."
