Chapter 561 The Prototype of Quantum Communication Satellite

It was already late at night when Jiang Chen came out of the office. Looking at the deep night and the flying snowflakes, Jiang Chen couldn't help but bury his chin in his scarf and sighed, thinking that he had wasted another whole day. He still has some things to do in Wanghai City, and he has to rush back to Xinguo after finishing. The virtual reality game server is about to start, and he doesn't have much time on his hands.

But when he looked at the second daughter who was holding his arm with a happy aftertaste on her face, the only little bit of dissatisfaction was washed away with the snow.

Nothing to say all night.

In the early morning of the next day, Jiang Chen came to the community center wearing winter clothes and stepping on knee-high snow. Just when he was about to go to the software development department to look for Du Yongkang, he saw this guy approaching him on his own initiative. Seeing the stack of documents Jiang Chen was holding, he immediately complained to Jiang Chen with a bitter face.

"Boss... Oh no, Marshal, our department is really short of manpower. Now, including me, everyone is doing the work of two people. Of course, I am not complaining, but I just want to invite you Go and urge Wang Qing, can the manpower I applied for be approved sooner?"

Seeing Minister Du being so pitiful, Jiang Chen couldn't bear it anymore, and couldn't help expressing his concern.

"is it so serious?"

"Otherwise... In our department, there is no one who does not work with dark circles."

Looking at the pitiful Du Yongkang and his dark bags under the eyes, Jiang Chen couldn't help but sigh.

Back then, the software development department was really an envy to others. The whole fish bone base, they are the easiest. Not to mention that the benefits are not bad, and you don't have to risk your life to copy and write those game codes all day long. I don't know how many people want to enter this department!

But now it's different. Internal and external troubles are settled, all wars, large and small, are basically over, and those knights with military exploits are all enjoying the blessings. All day long, he is not shooting targets at the training ground, or he is carrying a few guns and driving a car to patrol, puffing out his chest in front of those ragged refugees, enjoying the envious and respectful eyes.

In contrast, the people in the software development department are busy. Credit point payment system, maintenance of communication base station in Wanghai City. Market trading software, recently Chu Nan also proposed to build a nac area, integrating municipal administration, law enforcement, and tax payment...

And who does these things?

When Wang Qing thought about it, the software development department in the entire base knew more about computers. So he stuffed all these tasks into Du Yongkang's department.

"This Wang Qing is really... I'll go talk to her later.

"

Hearing this, Du Yongkang immediately nodded with a smile on his face, "Hey, I'll thank you then."

"You're welcome." Jiang Chen waved his hand and handed over the plan for developing and purchasing a VR social platform.

Looking at Du Yongkang who looked loveless. Jiang Chen patted his arm with some embarrassment, "Help me get the software on these two proposals, it shouldn't be too difficult. You can take care of other tasks for now... Cough cough, double the overtime pay, The manpower will be in place as soon as possible.”

Although I sympathize with his experience, the task that must be completed must be completed.

But watching Du Yongkang walk away with his sloppy footsteps, Jiang Chen always felt a sense of guilt in his heart.

How about adding some benefits to the code farmers in the software development department? For example, a carton of milk and a basket of eggs every week...

While thinking about this, Jiang Chen came to the logistics department and found Wang Qing who was busy checking the inventory data.

"It's not that I don't want to, but that no one applied for the job at all." After hearing Jiang Chen's intentions. Wang Qing pushed the glasses on the bridge of her nose, and explained with a wry smile, "Nowadays, even in the Sixth Street District, there is a shortage of computer talents. As soon as I recruit people, I will transfer them to him."

"Where is Vault 27? There should be computer talents there?" Jiang Chen asked.

"There are, but there are almost no computer-based professionals. And these experts in various fields basically have scientific research tasks. If they are transferred at will, they will lose sight of others." Wang Qing said.

With a scientific research project in hand, it is really not easy to mobilize. There is no better way. Jiang Chen had no choice but to instruct Wang Qing to increase the salaries of the employees of the software development department and post it in the recruitment information of the Sixth Street District. In addition, he also sent a text message to Zhao Chenwu. Ask him to pay more attention to computer talents in caravans outside the province. Any talent whose test rating is higher than c should be recruited as much as possible.

For women, the technical requirements can be relaxed. D and e can also be considered. After all, the entire department is full of male creatures. Jiang Chen felt a little pitiful for these dedicated single dogs...

The main purpose of coming back this time is to hand over the two proposals to Du Yongkang. Take a look at the girls and subordinates who haven't seen for a long time.

After walking around the community center, Jiang Chen came outside. Seeing that there was still some time, he stopped by 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, so I don't know how he is progressing now. It happened that there was still some time, so Jiang Chen stopped by and walked around here.

Seeing Jiang Chen approaching, Jiang Lin stuffed the things in his hands into the hands of a colleague in overalls, and walked up to him.

Stopping by the workbench, Jiang Chen saw the square-headed thing on the round platform, and asked involuntarily, "Is this a quantum communication satellite?"

"Almost, the appearance is like this. The key quantum communication components have not been installed yet, and we are still waiting for news from the No. 27 shelter. It is said that there is a small problem with the refrigeration device, and the size does not match and needs to be redesigned... How do you look at your expression, it seems that you are very disappointed?" Looking at Jiang Chen, Jiang Lin asked unexpectedly.

First of all, what I want to say here is that although quantum communication and quantum computer both have quantum in their names, they are actually two completely different things. The so-called quantum communication refers to a new type of communication method that uses quantum entanglement effect to transmit information, and it is a compound subject that combines quantum theory and information theory. On the other side of the world, recently this subject has gradually moved from theory to experiment. In the apocalypse at the end of the 22nd century, the research on quantum communication has already moved from the military field to the civilian field.

Compared with the fast but "unsafe" Crane particle waves and the slow research progress of gravitational waves, quantum communication technology is undoubtedly much more friendly to the people.

The advantage of being difficult to be cracked is needless to say, especially after a major breakthrough has been made 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 also become a reality.

As for the use of FTL communication? This is very useful!

If nothing else, let's talk about the current Internet. Now every household is connected to the Internet, but they all rely on submarine cables to connect to each other. Why has Google's global wifi plan been announced for so long and there is no movement? On the one hand, it is because the communication screens are crowded, and the most fundamental reason is that it is technically unfeasible to use traditional satellites as network connection nodes!

The height of the synchronous orbit is 36,000 kilometers, using traditional satellites

Satellite provides wifi service. Regardless of the attenuation of the electromagnetic wave signal, ideally the basic delay is above 500 ping. What is the feeling of the 500ping delay? Simply put, it means that when playing lol, you may not be able to see your own people.

Therefore, if traditional satellites are used to provide Internet services, it may be acceptable to send an email, but it will be more difficult to make a phone call, and forget about online games.

And the quantum communication satellite in front of Jiang Chen at this moment is such a powerful thing that "can overcome the difficulties that traditional satellites cannot overcome", and it is also a communication transfer station for the virtual reality network in the future.

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

"I thought it would look better."

Jiang Lin was stunned for a moment, then smiled and said, "In the universe, there is no need to consider aerodynamics. All shapes are the same. If you need it, I can also make it round. But the internal components have to be redesigned."

"No need, that's what I said." Jiang Chen said with shame.

The cost of building such a satellite is not cheap, and if he really wants to redesign one, it is himself that feels distressed. Because there is no use for these things in the wasteland, Wang Qing from the logistics department often complained to him about the unreasonable budget allocation of the Institute of Aerospace Science and Technology.
