Chapter 561 (2/2)

”Shelter 27? There should be computer talent there? ” Jiang Chen asked.

”Yes, there are, but almost none of them are computer-based. And these experts in various fields basically have scientific research tasks. If they are transferred at will, they will lose sight of one another. ” Wang Qing said.

With research projects in place, it's really not easy to mobilize. There is no better way, Jiang Chen had to tell Wang Qing to raise the salary of software development staff, and posted it in the recruitment information of the sixth block. In addition, he also sent a short message to Zhao Chenwu to let him pay more attention to computer talents in the caravan outside the province. Any talent with a test rating greater than C should be recruited as much as possible.

For women, the technical requirements can be relaxed. d. E can also be considered. After all, the whole department is full of male creatures. Jiang Chen feels sorry for these dedicated single dogs

The main purpose of coming back this time is to hand over the two plans to Du Yongkang and see the daughters and subordinates that have not been seen for a long time.

After turning around the community center, Jiang Chen came outside. Seeing that there was still some time left, he went to the Institute of Aerospace Science and technology and found Jiang Lin who was busy in the factory building.

Some time ago, Jiang Chen asked him to design a quantum communication satellite. I don't know how his progress is now. At the same time, Jiang Chen came here to turn around.Seeing Jiang Chen coming, Jiang Lin shoved the things in hand to one side, and his colleagues in overalls met him.

Stopping by the workbench, Jiang Chen saw the square head on the platform and asked, ”is this the quantum communication satellite?”

”Almost. That's what it looks like. The key quantum communication components have not been installed yet. We are still waiting for information from refuge 27. It is said that there is a small problem with the refrigeration device. The size does not match and needs to be redesigned What do you think of your expression? You seem disappointed? ” Looking at Jiang Chen, Jiang Lin asked unexpectedly.

First of all, although quantum communication and quantum computer have quantum in their names, they are actually two different things. The so-called quantum communication is a new way of communication that uses quantum entanglement effect to transmit information. It is a composite subject of quantum theory and information theory. Recently, the subject has gradually moved from theory to experiment. At the end of the 22nd century, the research on quantum communication has already moved from military field to civilian field.

Compared with the fast but ”unsafe” crane particle wave and the slow progress of gravitational wave, quantum communication technology is undoubtedly more user-friendly.

The advantage of being hard to crack is that there is no need to say much. Especially after the great breakthrough in the research on the transmission of ”non classical information”, the superluminal quantum communication, which was originally considered to violate the theory of relativity, has become a reality.

What's the use of superluminal communication? It's very useful!

Let's talk about the Internet now. Now every household is connected to the Internet, but all rely on submarine cables to interconnect. Why hasn't Google's global WiFi plan been announced for so long? On the one hand, it is because of the congestion of the communication channel, and the most fundamental reason is that the traditional satellite is used as the node of network connection, which is technically infeasible!

The synchronous orbit is 36000 km, and WiFi services are provided by traditional satellites. Without considering the attenuation of electromagnetic wave signal, the base delay is more than 500 Ping. What's the feeling of 500 Ping delay? In short, when you play lol, you may not see your own people.

Therefore, if you use traditional satellites to provide network services, it may be acceptable to send an e-mail, but it will be more difficult to make a phone call.

At present, the quantum communication satellite in front of Jiang Chen is such a powerful thing that ”can overcome the difficulties that traditional satellites can not overcome”, and it is also the communication transfer station of virtual reality network in the future.

Looking at the satellite, Jiang Chen touched his chin and said.

”I thought it would look better.”

Jiang Lin was stunned and laughed, ”in the universe, you don't need to consider aerodynamics. Any shape is the same. I can make it round if you want. But the internal components have to be redesigned

”No, that's what I said.” Jiangchen sweat face road.

The cost of building such a satellite is not cheap. If he really wants to redesign one, he is still distressed. Because the waste soil can't use these things, Wang Qing of the logistics department complained to him about the unreasonable budget allocation of the aerospace science and Technology Institute.
