Quantum technology, a new battle between the United States and China. BBC News



The news only appeared in specialized media.

The National Science and Technology Council of the United States published a new strategy for the development of the Quantum Information Science (CIC) in September.

15-page reports recommend Donald Trump government goals They need to develop and strengthen the CIC's capacities.

And to discuss the strategies presented, academics, government officials and country's leading technology and finance companies were invited to the White House, including Alphabet, IBM, JP Morgan Chase, Lockheed Martin, Honeywell and Northrop Grumman.

A $ 249 million investment was also announced in the field of science for 118 projects.

On the other side of the world, Something similar in China is happening.

China
China has given a large amount of money to research computer and quantum communications.

The Beijing government is building a new one Quantum of Scientific Information Laboratory in Hefei, In the Anhui province, it has a cost of 10,000 million dollars and it's about to open in 2020.

The first satellite telescope in quantum satellites began two years ago.

And in January, Jinan's "agitation" communications network was created, with only 200 users: military and government and private officials.

Since the two economic giants of the world are competitive in the CIC development, it shows the importance of this area, that is, It is a powerful world that will transform.

What is CIC?

Quantum Technology is the revolutionary revolutionary of the information processing, as explained in the BBC World, Alejandro Pozas-Kerstjens, Researcher at the Institute of Photonic Sciences of Barcelona and the Quantum Information Group Theory.

"All the information is encoded in a binary system – in zeremetan and others – but near the 60's it was found that there is a difference in the place where the information is stored," he explains.

"I mean, I can record classical information on a computer chip, as we have done now, but because we can also store smaller ones in other systems, for example in single atom or in small molecules".

binary code
All information is encoded in a binary system – in zeremetan and others – but where the information is stored, the difference can be made with that information.

"The behavior of these atoms and molecules, because they are so small, is dictated by other norms, and the norms that dictate the behavior of atoms and molecules are the norms of the quantum world of the quantum theory," says the scientist.

Thus, what quantitative scientific information is trying to use the new quantum properties that appear in small systems to improve the processing and transmission of information, among other things.

What does CIC mean is a revolution in the process of the information process, which opens up new opportunities in thousands of applications: health and science, drug production and industrial production, from the advancement of defense systems.

Quantum technology, experts say, "can change everything".

For this reason, one of the most powerful nations in the world is taking part in the competition in the CIC.

Quantum satellite

So far, taking into account advances in quantum technology, China can be said to be a leader.

In 2016, Beijing announced that it had the first quantum satellite telescope and one year later it was able to use this satellite. Encrypted communications can not be decrypted Through the eyes of others.

"They were two experiments: the first one obtained quantum satellite communications on the ground and, taking advantage of this satellite, communication between two points on the ground was encrypted quantum signal, which made a satellite repeater between these two points," explains Alejandro Pozas.

Quantum communication
China said that the encrypted communication used by its quantum satellite was not deciphered by the eyes of others.

If this capability is not capable of capturing information or arriving at its destination, we can not use technological information or information transfer today.

And although Chinese experiments were a conceptual proof, this country proved that this is possible.

"It's true that you can do it, but for now feasibility level has not been reached for a massive industrial application, "the researcher added.

Quantum computer, "holy grail"

It's not feasible in quantum computers.

They are trying to develop different companies in different nations Experimentally, it's still not marketed.

"The quantum computer is a holy apple," says the Barcelona Photonics Institute researcher.

"This is when all efforts are made directly or indirectly on the CIC field," he adds.

computer
All the efforts made in the CIC field are geared towards the development of the quantum computer.

The classic computer, which works twice, only works in two states, zero or one (turned on or off).

Quantum computing also works with the superposition of both states and uses subatomic particles to process data Quantitative quantities of classical computation.

Nowadays, despite the theoretical technology, some current calculations will be obtained, experts say, there will be classical computers.

Companies like the US, IBM, Google, and Microsoft are developing quantum computers.

And the same thing is happening in China, where private companies, like Alibaba and Baidu, are involved in the creation of quantum computers.

qubit
Google advances in the quantum computing race, providing the development of a processor with power of 72 kB bps.

But these computers are not easy to build: the main problem is the number of qubits that can be accessed by a single computer.

That is said Google will be past Development of a 72-kb power processor.

There is also a maintenance problem. These computers need to be kept in cold temperatures to operate.

Quantum computers work on room temperature are currently developing a research field that is focusing on national efforts.

revolution

But how is the quantum technology that is revolutionizing in the future?

As Alexander Pozas-Kerstjens explained, we can expect "the revolution like those that appeared on the first computers ".

computing
Quantum computing uses the subatomic particle movement to process the data in amounts established in the computation of chains.

"At the moment, they tell us a lot about things, such as manufacturing or prototyping medicines, or spending less fuel to optimize traffic routes."

"In this way, problems with a quantum computer can be solved".

But perhaps the greatest interest of governments is to use these quantum technologies In defense area, to be able to make safer art communications safer to detect intrusive aircraft.

And who can say that this quantum race has won?

As Pozas-Kerstjens says It's a "head of the bear" race.

"We might say that quantum computing may be at the forefront of the United States, but in quantum communication, China seems to have won."

"There are several aspects in the field of quantum technology, and many countries are trying to move forward or take on some of these aspects."
