China's quantum satellite transmission opens up the future of communication technology

China took the lead in launching quantum communication satellites on August 16 this year, achieving a major leap
forward in the field of quantum communication technology.
If China succeeds, it will have a significant impact
in the field of science and technology.

There are reports in the industry that while the use of quantum technology to teleport objects or people remains in science fiction, quantum communication has become a reality
.
The concept of quantum communication was born in 1993, and companies are now developing theoretically undecipherable quantum communication networks, and scientists are also working on quantum computers
that are more powerful than supercomputers.
China took the lead in launching quantum communication satellites on August 16 this year, achieving a major leap
forward in the field of quantum communication technology.
The satellite will bring quantum experiments into space and will lay the groundwork
for a global quantum communications network.

Félix Bisière, a quantum technology expert at the University of Geneva in Switzerland, pointed out that the quantum satellite launched by China proves the application prospects
of this technology around the world.
If China succeeds, it will have a significant impact
in the field of science and technology.
Future quantum technology will help build an absolutely secure and undecipherable global communication network, a new hack-proof Internet
.

The goal of China's Quantum Science Experiment Satellite Project is to use satellites to build an unbreakable communication network within two years, and use quantum transmission technology to share
quantum information between several bases on the ground.
The biggest advantage of quantum communication is that any attempt to intercept information is not only discovered, but also meaningless
.
Because without a quantum key, quantum information
simply cannot be understood.

At present, a number of enterprises have put quantum key distribution technology into the market
.
China has also established such networks
between banks or government agencies, experts said.
The problem is that these fiber optic networks can only function
over distances of tens of kilometers.
With quantum satellites, however, this range will expand
.
Fiber optic networks are more disturbed on land, but much less "noisy" in space that can interfere with photons
.
In fact, the Quantum Science Experiment Satellite Project conducts quantum communication experiments at a distance of 1,200 kilometers, far exceeding the farthest record
of 300 kilometers on land.

Bisière believes that quantum transmission will become an important tool
for future communication technologies.
Germán Sierra Rodro, a researcher at Spain's National Research Council, agrees that quantum transmission will become a key protocol
for the transfer of information between quantum computers.

Bissier pointed out that the biggest advantage of quantum computers is that they have powerful computing power to simulate complex chemical reactions, which can help optimize industrial processes and develop drugs
.
In addition, quantum computers are also faster
.
Chinese scientists involved in the Quantum Science Experiment satellite project point out that tasks that currently take 100 years for the most powerful supercomputers, such as Tianhe-2, can be completed by a quantum computer in just 0.
01 seconds
.

In addition, quantum technology can also be used in the field of metrology, for example to develop more sophisticated atomic clocks and more sensitive sensors
.
Quantum technology can even be used in the field of
astronomy.
Astronomers have proposed that quantum technology could be used to connect several astronomical telescopes or build telescopes
with higher resolution.
The quantum world is getting closer
and closer.
