From Almighty Scholar to Chief Scientist

Ever since, during the New Year's Eve dinner, I asked.

"Xiaoxiao, everyone on the Internet is saying that the new technology you made recently is very powerful?"

"It's not a question of whether it's powerful or not, it's the rare kind..." Lin Xiao thought for a long time and found that he didn't know how to explain it to his parents so that they could understand, and finally said simply: "Anyway, it's quantum mechanics, the very powerful one."

"Technology and hard work?" Father Lin asked.

Hearing these words from his father, Lin Xiao was taken aback for a moment, and finally couldn't help covering his face, and said, "Dad! Stop shaking your hands!"

Hearing this kind of words from the elders always gave him a sense of the collapse of the world.

But at this moment, the sound of fireworks exploding suddenly sounded outside the window.

Yang Rong next to him glanced at the fireworks blooming outside the window, and couldn't help saying, "Hey, there are still people who dare to set off fireworks."

And Father Lin said with a smile: "It seems that the higher authorities have approved the setting off of fireworks and firecrackers again. I don't know what's going on, but it's a good thing."

"It feels a bit like the Chinese New Year." Yang Rong also laughed.

At this time, Lin's father patted Lin Xiao's shoulder, said with a smile: "How is it? After eating, let's go and let it go. It's been a long time since we played."

Only at this time did he notice that Lin Xiao seemed to be in a daze looking at the fireworks outside the window.

"Xiaoxiao?"

Lin Xiao came back to his senses, then smiled and said, "Okay."

……

Firecrackers can be set off during the Chinese New Year. This matter quickly became a hot topic and aroused many people's discussions. Although people don't know why the ban on fireworks and firecrackers was lifted again, it is known that the vast majority of people I feel very happy.

The young people called their partners to set off the long-lost firecrackers, and even the adults would go to play and miss the past childhood.

As for Lin Xiao, he knew that the reason for firing the cannon was all because of his proposal after the successful realization of controllable nuclear fusion.

But as he who brought all this, he didn't have much time to enjoy this kind of entertainment.

After experiencing it with his father on the night of New Year's Eve, he entered his own research again the next day.

After all, just three degrees of freedom is not enough, his goal is five degrees of freedom.

Ever since, he was studying again and spent this Spring Festival holiday.

And one month after returning to Feishi, he once again designed a four-degree-of-freedom entanglement source observation device.

……

Chapter 486 Astonishing material on the surface of the moon tablet

"How do we conduct this four-degree-of-freedom experiment?"

"With four degrees of freedom, is it possible to go to the moon?"

"It might work?"

In the laboratory, everyone looked at the new device in the middle with curious eyes on their faces.

After all, this is four degrees of freedom!

In fact, in the past month, they have conducted the second ultra-long-distance experiment on the previous three-degree-of-freedom observation device. From the northern end to the southernmost end, a distance of 5500 kilometers was measured, and the final result is still very gratifying, because they succeeded.

Obviously, this is an astonishing achievement. The 5500-kilometer direct communication, compared to their previous method of placing a relay station in every other city, and then crossing dozens of cities, was able to realize the communication of several provincial capitals. too much.

This means that no matter where they are in the country, they will be able to directly transmit confidential information through quantum communication.

The most important thing is that it is still transmitted directly, without the use of quantum satellites.

The biggest problem with quantum satellites is that they are floating in the sky and cannot achieve effective defense. If a war really comes one day, then obviously, the other party can try to destroy the quantum satellites directly. In this way, the quantum communication they built before The trunk line is tantamount to wasting directly.

Of course, their Micius has actually considered this kind of thing at the beginning, so the satellite orbit where the Micius is located is a sun-synchronous orbit, which is far enough from the earth, and it is difficult to achieve an attack on the Micius. Still pretty big.

However, although it is difficult, they have to take precautions against this matter, so it is more stable to realize direct communication on the ground.

Now, they have achieved direct quantum communication across 5500 kilometers, so this problem is naturally not a problem.

Therefore, from a strategic point of view, this will completely ensure their information security, and they will no longer have to worry about information leaks and other issues.

Of course, 5500 kilometers is only the limit of their current measurement. This does not mean that they have reached the limit of the three-degree-of-freedom observation device, so they still have the opportunity to achieve longer distance measurement.

Originally, they did have this plan. They planned to cooperate with both the navy and the air force. When the time comes, let the navy go to the high seas, and then they will cross tens of thousands of kilometers on the mainland to see if they can achieve contact. The Air Force is to let the Air Force go to the sky to try to see if the Air Force's aircraft can achieve quantum communication with the ground during high-speed movement.

However, none of them expected that Lin Xiao would make this four-degree-of-freedom observation device so quickly.

The three-degree-of-freedom observation device, less than three months after its birth, has directly become an outdated technology.

Although I was very surprised that Lin Xiao had once again achieved a technological breakthrough so quickly, but there was no way to do it. Since we have done it, we can only accept it.

So now they have to start discussing how to conduct experiments.

But speaking of it, they all felt dumbfounded. They don't know how to conduct experiments now?

If there is another experiment, they will have to test it from the North Pole to the South Pole

"Maybe, now we should go to the space station for an interview?"

Someone couldn't help asking.

"It doesn't make sense." The other person shook his head and said, "After all, Mozi is in the sky."

"That's true." The person who proposed thought for a while, and finally nodded.

indeed.

The sun-synchronous orbit where Micius is located is 1400 kilometers away from the farthest point of the earth, but it is farther than their space station.

The orbit of their Tiangong space station is only more than 400 kilometers away from the earth, far less than 1400 kilometers away.

As for why Micius can achieve 1400 kilometers of quantum communication, it is actually because of quantum decoherence. On the surface of the earth, the speed of quantum decoherence is extremely high, which also caused their direct quantum communication on the surface of the earth to be greatly affected. It is not bad to have a distance of hundreds of kilometers, so the current 5500 kilometers of direct communication surprised them so much.

In the cosmic space, since it is basically empty, there is almost no environmental interference, so the influence of quantum decoherence is greatly reduced, and longer-distance communication can naturally be realized.

It is precisely because of this that they have the courage to challenge the gap between the earth and the moon as high as 40 to [-] kilometers, just to achieve a few thousand kilometers of communication on the earth.

But unfortunately, the size of the earth has become a barrier to their experiments.

After all, the diameter of the earth is only more than 1 kilometers, and they have all achieved 5500 kilometers in three degrees of freedom. Now they all have four degrees of freedom. Can't they multiply this distance by 2?

So right now, they don't know what to do.

"Lin Xiao, what are your plans?"

At this time, Pang Wei in front asked Lin Xiao.

Obviously, on this point, Lin Xiao still needs to make this decision.

At this time, Lin Xiao was also thinking about how to carry out the experiment next?

They have confirmed the feasibility of the four-degree-of-freedom observation device. After experiments, this four-degree-of-freedom observation device can transmit information, and the next step is to verify the long-distance transmission information of this device.

But now it seems that it is impossible to go to the moon.

So in the end he thought about it, and said, "Let's do it this way. Next, you try to increase the number of bits transmitted. In addition, try to see if you can achieve communication from the North Pole to the South Pole."

"Well, I see." Pang Wei nodded without any objection, after all, they can only do these two things now.

From the North Pole to the South Pole, that is, the two farthest points that can be realized on their earth.

As for the other item, increasing the number of bits transmitted is related to how much information they can transmit at one time.

After all, quantum communication is not like the current network, which can transmit a large amount of information. The size of the information that can be transmitted by quantum communication is limited by its entanglement quantum. Therefore, only by increasing the size of the information that can be transmitted can its function be improved. Otherwise, If only one bit of information can be transmitted in one second, it might as well be transmitted directly by radio waves.

This is equivalent to a person living in the country. Although he is connected to an advanced network, since the upload speed is only 1B per second, when he wants to transfer a G file to a neighboring city, it is better to directly upload the This G file is copied to the USB flash drive, and then the file is sent directly to it on horseback.

Therefore, it is also very important to increase the number of bits that can be transmitted per second.

"What about you? What are you going to do?"

And Lin Xiao smiled and said, "I have to help them and speed up the date of the next manned moon landing plan."

Pang Wei was taken aback, "Speed ​​up? How do you speed up?"

"Of course it is to help them study the spacecraft that can go to the moon."

"What, a spacecraft?"

Pang Wei's eyes widened immediately. Lin Xiao had just developed this four-degree-of-freedom quantum entanglement observation device, and then turned around to study spacecraft?

And according to Lin Xiao, it is still the kind of spacecraft that can go to the moon.

Dare he plan to start a moon landing program directly in order to test this four-degree-of-freedom observation device?

How did this give Pang Wei the feeling that he made dumplings for a plate of vinegar?

Of course, if he knew Yue Shisi, he would definitely not think so.

Because Lin Xiao obviously researched this quantum communication technology in order to go to the moon.

"Yes, the spacecraft, otherwise, the moon was so expensive last time, they must not be willing to play like this."

Of course, Lin Xiao didn't explain anything to Pang Wei, spread his hands, and then said to Pang Wei who was still surprised: "Okay, you can arrange the rest of the matter, and I should go back to Beijing."

"Of course, don't forget that our project is not completely over yet. After all, our project goal is five degrees of freedom."

Pang Wei recovered from Lin Xiao's words just now, and finally said helplessly: "Okay, I understand, you go, and leave the other things to me."

Lin Xiao smiled slightly, "Okay, that's it."

Then he turned his head to look at the other researchers in the laboratory, and said with a smile: "Thank you for your hard work during this time, let us see you at the next node before success."

The other researchers have just heard that Lin Xiao is going to study the spacecraft next time. At this time, there are all kinds of surprises and envy on their faces, and after hearing Lin Xiao's farewell words, they are also all He quickly waved his hand and said, "It's not hard work, it's all thanks to Chief Lin."

Lin Xiao smiled, and then said no more. After saying goodbye again, he left the laboratory. Next, he would hurry up and start research on aerospace aircraft.

And the others couldn't help but sigh with emotion when they saw Lin Xiao's vigorous back.

"Perhaps in this world, Chief Lin is the only one who can study quantum communication and spacecraft at the same time?"

"Sometimes it's unimaginable..."

When they were all feeling emotional, Pang Wei said: "Okay, let's start to increase the transmission size of bits according to what Chief Lin said. At least, before the next moon landing plan, we have to achieve at least one bit per second." The transmission speed of [-] bits, otherwise, when people transmit a photo back, it will not be as fast as wireless telegraphy."

"Yes!"

The researchers present responded immediately.

"In addition, contact the navy that we have cooperated with before, as well as the scientific research stations in the Arctic and Antarctic. When the time comes, we will go to the poles to do experiments together."

"By the way." Speaking of this, Pang Wei paused, and then said with a smile, "Take a trip."

The researchers present immediately cheered, and then returned to their posts one after another to start the next research work.

……

Time passes quickly.

After Lin Xiao left the Quantum Physics and Quantum Information Research Department, he packed his bags and returned to Shangjing.

Next, he will start research on aerospace aircraft, so naturally he needs relevant help.

Of course, the most critical thing is the place where the experiment is carried out.

So, he opened his mouth and asked for a huge sum of money to build the Dingguang Aerospace Research Institute.

And this huge sum of money is as high as [-] million, because Lin Xiao's aerospace research institute not only has those indoor experimental sites and instruments, but also has an outdoor experimental site.

As for his outdoor experimental site, it is an airport runway that is long enough and big enough.

The world's largest aircraft, the An-225 transport aircraft, weighs 640 tons. If it wants to take off, it needs an airport runway of 3500 meters to take off.

The Long March 4000 carrier rocket has a maximum take-off weight of more than 225 tons, which is nearly seven times that of the An-[-].

The aerospace plane, which is both an aircraft and a spacecraft, naturally cannot be smaller than the An-225 in terms of mass. Of course, it may not necessarily be larger than the rocket, because more than 80.00% or even 90.00% of the rocket is fuel.

And because the aerospace plane can take off with the help of air buoyancy like an airplane, it can replace nearly two thousand tons of rocket fuel with hundreds of tons of aircraft fuel. After all, even if it is An 225, it only needs 300 tons of fuel. up.

Of course, because of the greater weight, the take-off runway required for aerospace aircraft will be longer.

Therefore, the runway that Lin Xiao plans to build must first be very long.

According to his calculations, at least 8000 meters long would be needed. Of course, just in case, he decided to directly build a [-]-meter runway.

Ever since, he asked for so much money at once.

Of course, the higher-ups also knew that he was doing it for Yueshisi, and the aerospace plane was not only meaningful for exploring the moon, it was also very important in terms of strategic position.

After all, once aerospace aircraft are realized, it means that they will have the ability to strike from orbit, and this kind of strike has almost no solution.
