Chapter 120: Building a Space Quantum Internet

"Alright, let's demo it here." Academician Hu ended the demonstration, "This quantum computer can complete the operation of any problem, unlike the previous computers that can only solve a certain problem. ”

"I've given you all the information, how long will it take for you to finish reading it?"

"Three days, I'll take a look at it all night these days." Lin Yu said for a while, although he had read it all, but he had a system to help others didn't know, and he didn't dare to say it.

"I suggest you extend it a little", Academician Hu didn't expect Lin Yu to work so hard, and reminded with some surprise, "You can work hard in scientific research, but don't work too hard, otherwise your body will be unbearable, which in turn will affect your efficiency." ”

"Thanks for the concern, I know." Lin Yu smiled, "I know my body best, after all, I know this kind of thing best." ”

Seeing this, Academician Hu didn't persuade him, but just admired him even more, "It's good that you know it in your own heart." ”

"Come on, I'll take you to familiarize yourself with the environment, and don't rush to study the materials at a moment's notice, after all, it's still a long time."

Lin Yu followed Academician Hu around the entire supercomputing center, and after knowing where the canteen and Academician Hu's office were, he went back to the dormitory.

After all, it is estimated that in the future, it will be the dormitory, the canteen, and Academician Hu's office.

When Lin Yu returned to the dormitory, he started the mode of crazy work, constantly sketching and drawing on the realistic data, which is what he did in the system research institute, so he is very familiar with it now.

He is going to make a research trace, just like when a junior high school and high school teacher checks the workbook, the students who can copy their homework will even copy the traces of the questions.

This work is not only to supplement the research traces, but also to outline the information that you need most, of course, the main purpose is the traces, the so-called acting to play a full set.

During this time, in addition to carefully sketching the materials he needed, Lin Yu gradually made a grasp of how the entire quantum computer could be scaled down.

Wang Hong and Academician Su have absolutely good evaluations of him, that is, he is a person who likes to strategize and does not like to do anything risky.

Even the existence of the system has to be carefully covered up, trying not to make his research seem so abrupt, so that everything looks traceable.

Moreover, the technology and design that Lin Yu obtained from the system are completely in line with this era, and there is nothing too sci-fi, which is why Lin Yu can take out these technologies and designs with confidence and boldness.

Except for the bionic released by the system, it has been almost eight or nine months, and Lin Yu still doesn't dare to touch it at all.

He has been thinking about when the research of androids will be taken out to be foolproof, and now he has an idea in his heart, he wants to completely manufacture the quantum computer, and when this research results are developed, then the research of androids will not be so dazzling.

He gradually had a plan in his mind.

Three days passed, he went to Academician Hu's office with the sketched materials, and in order to make his appearance of staying up late more realistic, he only slept for three hours a day, and finally let the dark circles crawl on his face.

"Academician Hu, I have an idea." Lin Yu picked up the materials and showed them to Academician Hu, "Look at this, we can talk about the deconstruction of the entire framework, take out a part of the things and send them to the outside of the satellite, in addition, the heaviest part of the entire quantum computer is actually the refrigeration equipment, remove this part, then the weight of the entire computer will be greatly reduced." ”

Academician Hu nodded, "We have already considered these. ”

"My idea is to make the entire satellite into a quantum computer, a quantum communication repeater, and a network transmission equipment all in one design."

"Our biggest problem is how to connect them all, so let's put them all together, which is the easiest way to do it." Lin Yu said.

These are actually Lin Yu's own ideas, after all, the information given by the system only has the design of a quantum computer, but there is no content of the quantum Internet.

"I think that since the country wants to make a space Internet, then it must have studied a way to transmit network protocols without a physical network line link, right?"

Academician Hu replied to Lin Yu affirmatively, "For quantum communication, this is very basic. ”

If you want to build the Internet, then you need to link one computer to another, and the Internet currently used by Bluestar is developed on the physical line, the server and the network line are connected, and finally all the computers are connected together through the network terminal.

Only by connecting the Internet together can data be transmitted and accepted, therefore, in Bluestar, computers need to be connected to each other through optical cables, twisted pairs, and radio waves, and these specific hardware constitute the physical layer and the foundation of the Internet.

The space quantum Internet can abandon these specific lines and directly connect quantum computers to each other, forming an Internet that cannot be destroyed by attacks except for directly destroying the computer itself, which is very safe.

"The quantum Internet network we built on the ground is like this, and we only need to add a quantum signal receiving and transmitting device to an ordinary computer, and we can completely abandon the limitations of physical lines."

"It's just that we're still piloting, and the ground environment of Blue Star is relatively bad, not as good as the space environment at all, so we first chose the construction of the space quantum Internet, and I think the United States also found out about it."

"Only after quantum computers enter thousands of households can the quantum interconnection network on the surface of the blue star be built."

After this conversation, they have established a major consensus, which is to make the entire satellite a quantum signal transmitter and receiver with all functions.

It functions the same as the signal towers on the surface of the Blue Star.

Determined this goal, Lin Yu began a half-year study, in which he personally carried out manufacturing, changed and changed the design drawings with Academician Hu and his team, and invited a professional team in aerospace for testing.

Although Lin Yu himself only came out of the space center not long ago, manufacturing spacecraft and testing spacecraft are actually two jobs, and many testing instruments are not operated by Lin Yu, so the detection of satellites can only be handed over to a professional team.

After passing the test, the whole team cheered, and their five-year dream was half achieved today.

As long as the quantum internet built by the satellite is detected on the ground, then they can completely relax.

"Thank you for half a year of hard work, we are about to succeed." Academician Hu couldn't help but smile.

"No, we haven't made it yet." Lin Yu was not relaxed.

"You're right, we're only halfway through the process before these satellites are launched and the space quantum internet is successfully built." Academician Hu nodded.
