Chapter 270 Quantum Direct Communication
Dean Bai Xinzhou listened carefully to what Mr. Yang said, nodded thoughtfully, and made a decision in his heart. The next second, he turned his head and looked at the audience again, and followed the procedure to vote.

"Please raise your hands if you think the steady-state micro-beam lithography factory proposed by Academician Xu and Professor Zhao Xiang is acceptable."

Almost as soon as Bai Xinzhou finished speaking, it became clear that the vast majority of academicians and professors in the audience raised their hands without hesitation, and it was obvious that they recognized and supported the steady-state micro-beam lithography factory plan from the bottom of their hearts.

One can even see Luo Yajie, an academician from the Institute of Optoelectronic Technology.

Logically speaking, he and Xu Yuan have become competitors now.

If a lithography factory can really be realized, research on traditional extreme ultraviolet lithography machines will basically lose its meaning.

But he knew better.

Whether it is the research on domestic extreme ultraviolet lithography machines or the establishment of lithography factories, the purpose is to solve the problems of domestic high-end chip manufacturing.

On the other hand, the approval of Xu Yuan's project also reduced his pressure in disguise.

He has been under a lot of pressure these days.

I am afraid that in the end, we will not be able to successfully develop a domestic extreme ultraviolet lithography machine.

Failure to meet people's expectations.

Now that we have the new direction of photolithography factories, it can be said that this provides domestic content with an opportunity to make mistakes.

Don't put all your eggs in one basket.

To be honest, if Xu Yuan's lithography factory can really succeed, even if the results of their project lose their meaning, I believe everyone will still be excited.

I am happy that China has achieved technological overtaking in the field of high-end chip manufacturing.

In addition, after listening to the project proposal, he was also optimistic about steady-state microbunching. As Xu Yuan was in charge of the project, he definitely expressed his support.

When Bai Xinzhou saw the voting result, which was what he had hoped for, a smile suddenly appeared on his face, and he immediately announced the news publicly:

"Since everyone has no other opinions, I declare that the Steady-State Micro-Beam Lithography Factory Project has been officially launched. The institute will fully support this project, and we hope that you can produce results as soon as possible."

After listening to the dean's words on the stage, Xu Yuan's expression remained calm and he was not surprised by the result.

After all, the theory of steady-state microbunching has been experimentally verified.

It's not an unrealistic fantasy.

Under the current circumstances, if we finally find a new path, we must hold on to it.

Even if you don't succeed in the end, you have to try.

Even those who held conservative attitudes and did not want to see the institute divert resources to other projects and chose not to raise their hands simply gave up voting and did not express opposition.

It was Zhao Xiang next to him.

After hearing that the project was successfully approved, he couldn't hide the excitement on his face.

Turning around, he said excitedly:
"Our proposal was approved, which is great."

Xu Yuan met Zhao Xiang's gaze, smiled and nodded in agreement, expressing his understanding of this expression.

Perhaps even Zhao Xiang himself did not expect that the steady-state micro-beam theory he accidentally proposed could be successfully verified and discovered so much value, but no matter what, this theory was proposed by him. At this moment, when he learned about the establishment of the steady-state micro-beam lithography factory project, his feelings were naturally difficult for others to understand.

But Xu Yuan did not forget the important matter.

When Zhao Xiang calmed himself down, he raised his gaze to the dean and talked about an important matter regarding the progress of the project.

"Dean."

"I hope to transform the high-energy synchrotron radiation light source device under construction so that it can be used in a lithography factory, which will greatly shorten the research and development cycle of the project."

The high-energy synchrotron radiation light source facility located in Yenching is a project of the Academy of Sciences.

Since the light source of the lithography factory needs to be modified, it must be approved by the institute. This is a necessary process.

Bai Xinzhou listened to everything Xu Yuan said.

I started thinking about it immediately.

The high-energy synchrotron radiation light source, as a key basic science building of the Academy of Sciences, will provide relevant experimental conditions for laboratories in various universities after its completion. A lithography factory was not considered in the planning.

Now that the situation has suddenly changed, it is feasible to change the use at this time.

The key is also of great significance.

Compared with basic science construction, solving the problem of high-end chip manufacturing is undoubtedly the first thing to consider at the moment.

As for this basic science building, it can be built at another location.

With his thought lingering here, Bai Xinzhou made a decision immediately. Without wasting any more time, he immediately gave an affirmative answer.

"This is related to the construction progress of the photolithography factory. The institute agrees to this matter."

"Thank you, Dean."

"We will come up with a feasible transformation plan as soon as possible." Xu Yuan took over the conversation and answered.

The discussion on the steady-state micro-beam lithography factory project has basically been finalized, and it depends on what the final result will be. Bai Xinzhou did not waste everyone's time and immediately announced the end of the meeting.

Maybe there was too much information to digest in today's meeting.

There were quite a few people in the hall who did not leave immediately. Instead, they gathered in groups of three or five and discussed excitedly with each other. They were talking about the lithography factory.

"This plan is really creative. It turns the difficulties we face into areas we are good at."

"Who said it wasn't true? When I first saw this plan, my whole brain was shocked."

“It’s truly a genius idea.”

"I hope we can produce results as soon as possible so that those overseas guys can take a good look, especially the CEO of Ames."

"For now, we still need to solve many technical problems to realize the lithography factory, but since the project leader is our academician Xu, I am still optimistic."

"I still think we should focus on developing extreme ultraviolet lithography machines. The path others have taken at least shows that it is feasible."

……

Xu Yuan naturally listened to everyone's discussion.

But he did not step forward to participate.

The steady-state micro-beam lithography factory project has been approved, so all we need to do is to produce actual results to prove the feasibility of this project. There is no point in arguing at this time.

What they need to do most now is to come up with a plan to transform the high-energy synchrotron radiation light source device as soon as possible.

This will also allow the construction team to resume construction as soon as possible.

After all, if they don’t deliver, they won’t be able to officially carry out the experiment.

He had discussed this with Zhao Xiang before, so it didn't take too long.

However, just as the two were about to leave, they noticed that Mr. Yang was walking towards them.

They took the initiative to say hello before they even got close.

"Mr. Yang."

"It's up to you guys from now on. I look forward to seeing the day when you get a surprise." Elder Yang patted them on the shoulders and said with a smile, "If you have any questions, you can always come and talk to me."

"That's great." Zhao Xiang was the first to respond.

Xu Yuan nodded and said, "We will."

Considering Mr. Yang’s age, his body is already somewhat exhausted from attending such a long report meeting.

After talking to Xu Yuan and the others, he left accompanied by someone.

Zhao Xiang and Xu Yuan planned to return to their office at Qinghua University first to come up with a practical plan for the transformation of the high-energy synchrotron radiation light source device.

Besides, such a large national key project cannot be completed by just the two of them.

In addition to absorbing all the people who have previously participated in the steady-state microbeam experiment into the project, we will also recruit people from all over the country.

It is worth mentioning that the two walked out of the hall and went downstairs.

Xu Yuan saw a familiar figure.

It was Academician Luo Yajie from the Institute of Optoelectronic Technology.

Judging from the other party's behavior, it seemed that he was waiting for him here.

Although he didn't know what the other party wanted, he quickened his pace and went towards him.

And take the initiative to say hello before approaching.

"Academician Luo."

"Are you waiting for me on purpose?"

"I want to thank you." Luo Yajie nodded and said truthfully.

But when Xu Yuan heard this, he couldn't help but feel something strange, and he was unable to react for a moment.

"Thank me?"

Faced with Xu Yuan's question, Luo Yajie seemed a little embarrassed.

He paused before explaining.

"That's true. If you hadn't found the steady-state micro-beam lithography factory, a brand new research direction, our team would have been under much greater pressure."

"In addition, I am also very optimistic about your research direction."

“Perhaps the ultimate solution to the domestic semiconductor dilemma will still depend on lithography factories.”

Having said this, he seemed to feel that something was wrong, and as soon as he finished speaking, he added another sentence.

"Of course, we will also go all out in the research of extreme ultraviolet lithography to see who can make progress and complete the project first."

After listening to everything the other party said, Xu Yuan immediately understood what was going on. He felt a little amused and didn't know how to respond.

But since it is a fair competition between opponents, there is no reason not to accept it.

With his mind working quickly, he took the initiative to reach out and shake hands with the other party in the next second, accepting the other party's competition.

"It seems we have to work harder."

After talking, they didn't waste too much time and left after saying goodbye.

……

The Spring Festival is approaching.

During the holidays, Xu Yuan, Zhao Xiang and other confirmed project members were very busy. They discussed online from time to time the renovation plan of the high-energy synchrotron radiation light source device.

Since it is to be used as a light source in a lithography factory, various details must be taken into consideration.

Ensure that subsequent experiments can proceed normally.

It can be said that it is directly related to the success of the steady-state micro-beam lithography factory, and there must not be any mistakes.

Otherwise, it will be difficult to make changes once the light source is built and officially delivered.

For this reason, Xu Yuan set high and strict standards for everyone, and discussed every detail many times before officially confirming it after it was correct.

Just after the Spring Festival holiday, the renovation plan was finally released.

This is all thanks to everyone's persistence.

Xu Yuan also had a surprising discovery about this.

That is, after the transformation plan of the high-energy synchrotron radiation source device was completed, the progress bar on the virtual panel in front of him increased again. Although it was only a few percent, it indirectly showed that their transformation plan was feasible. So Xu Yuan did not dwell too much on the plan.

Construction officially began soon.

After all, time waits for no one. It is better to start construction earlier and deliver the product earlier, and then carry out experiments as soon as possible.

However, during the transformation and construction phase of the high-energy synchrotron radiation light source device, they can only focus on theory.

And in addition to the light source, there are technical issues that need to be solved.

In this way, once the high-energy synchrotron radiation source is put into use, it will be able to get back on track immediately.

-

As time passes by.

In the next few months, good news frequently came from the Institute of Optoelectronic Technology, which aroused the emotions of netizens each time and allowed everyone to see the progress of domestic extreme ultraviolet lithography machines.

It is precisely because of this positive feedback that everyone is becoming more and more confident in solving the problem of domestic high-end chip manufacturing.

But at the same time, everyone also discovered a problem, that is, Xu Yuan's name was not on the list of domestic extreme ultraviolet lithography machine research and development projects.

You should know that when the Academy of Sciences first decided to develop its own extreme ultraviolet lithography machine, Xu Yuan's name was indeed included in the list of project leaders announced.

It is precisely because of this that everyone's self-confidence is inspired.

I believe that as long as Xu Yuan participates, new miracles can be created.

As it stands, this does not seem to be the case. As the matter gradually ferments online, the number of netizens participating in the discussion continues to increase.

This leads to negative emotions later on.

Some netizens believe that Xu Yuan must have participated in the project research.

It has not been published due to confidentiality.

Others think that Xu Yuan did not carry out the extreme ultraviolet lithography machine project. After all, Xu Yuan has no relevant experience.

After the topic becomes a hot topic, various messages can be seen in the related comment area.

"The person in charge of the photolithography project of the Institute of Optoelectronics Technology does not include Academician Xu. I guess the list published by the Academy of Sciences is just a simple listing of names."

"It seems that I was a little too optimistic before."

"Although there have been many good news recently, there has been no substantial progress. We have not even reached the 22-nanometer specification. I really can't think of any way to get the level of overseas extreme ultraviolet lithography machines."

"After all, Academician Xu is not omnipotent, so the current situation is understandable."

"Is there really no way for us to solve the production and manufacturing problem of high-end chips?"

"Anyway, I firmly believe in Academician Xu. It is normal to choose confidentiality before the project progresses. Maybe there will be a surprise someday."

“Who knew at the time that we would suddenly have fifth-generation aircraft?”

"Especially at this time, we should maintain our confidence and never let others laugh at us."

……

Xu Yuan had naturally occasionally seen things being discussed online.

But he chose not to respond.

After all, all scientific researchers are focusing their energy on the project right now, and no one has the time to care about the network situation.

There is no need to solve it.

Anyway, once the good news is announced, the wind direction will reverse instantly.

In particular, the advent of the steady-state micro-beam lithography factory will surely give everyone a huge surprise, and I am afraid that some people will not be able to believe it by then.

And when the time came into July.

However, Xu Yuan did not continue to stay in Yanjing, but took time out to go on a business trip to Luyang.

During this period, although he focused his main energy on steady-state microbunching, he did not forget the Quantum Innovation Institute, where he was carrying out coding design work for quantum direct communication systems.

Because the design of the quantum direct communication system has already been on the right track.

Under the leadership of Academician Pan Xianfeng and with his remote guidance, the entire system coding was finally completed.

It did not affect the progress.

Since the next thing to be carried out after the completion of quantum direct communication is the quantum key distribution experiment, which is also related to the subsequent application of quantum drones, Xu Yuan must participate in the experiment in person.

It just so happens that the high-energy synchrotron radiation light source device is still under construction after the transformation, so it will not affect the lithography factory.

2017 7 Month 13 Day.

Thursday.

Institute for Quantum Innovation.

As soon as Xu Yuan got out of the car, he saw Pan Xianfeng coming towards him with a group of people.

He did not forget to take the initiative to greet people before and after approaching.

"Academician Pan."

"Thank you for your hard work during this period. Did you encounter any trouble?"

When Pan Xianfeng heard what Xu Yuan said, he quickly took over the conversation and responded: "We can't say it's hard work. Besides, if it weren't for you, our institute would not have been able to take on such a big project." He kept a smile on his face as he spoke.

What he said was absolutely correct.

After all, the Quantum Innovation Institute was established only a short time ago. Not to mention any impressive projects, even personnel are in short supply.

Thanks to Xu Yuan's help, they successfully completed the quantum direct communication system. As long as the key distribution experiment of the quantum satellite is successful and the news is announced to the outside world, the Quantum Innovation Institute will immediately gain a firm foothold in the global quantum field.

It has become an indispensable existence in the study of quantum mechanics.

From this point of view, it was all thanks to Xu Yuan.

How could one ask for anything in this situation?

In addition, the outside world may not be clear about this, but they know that Xu Yuan is in charge of a key project that is related to the future development of the domestic semiconductor industry.

It is a rare opportunity to be able to come here specially to participate in the quantum key distribution experiment.

Next, Xu Yuan exchanged a few words with everyone, and then without wasting any more time, he went to the quantum laboratory in the research building under the leadership of Pan Xianfeng.

"All preparations have been made, and the quantum satellite has also been booked. We can start at any time."

On the way, Pan Xianfeng and Xu Yuan explained the situation.

From the slightly excited tone, one can tell that he is a little impatient.

"Ok."

Xu Yuan nodded in response.

He was very impressed with Pan Xianfeng's strength in the quantum field. Since the other party said that he could start the experiment at any time, it meant that there was no problem.

Therefore, after quickly arriving at the quantum laboratory upstairs, Xu Yuan first checked the direct communication system.

After confirming that everything was correct, he turned to Pan Xianfeng and said:
"Academician Pan."

"Then let's get started."

"I've been waiting for this day for a long time." Pan Xianfeng smiled when he heard the voice, and suddenly became serious after he finished speaking.

Quantum key distribution, also known as quantum cryptography.

It uses the transmission and measurement of quantum superposition states to achieve secure quantum key sharing between the communicating parties, and then achieves unconditional and absolutely secure confidential communication through a one-time symmetric encryption system.

Quantum direct communication uses quantum states as carriers to encode and transmit information.

The dual-channel structure of the traditional confidential channel has been changed.

It can not only sense eavesdropping, but also prevent it. In addition, point-to-point quantum direct communication between satellites and the ground and between cities can reduce the number of relays, lower costs and communication delays.

As long as today's experiment is successful, it will lay a solid foundation for establishing long-distance quantum direct communication.

Once the relevant research is mature, it can be applied to drones.

At that time, drones will be able to perform various tasks normally through quantum communication without worrying about signal interference and interception.

By that time, quantum drones will become a real nightmare for the enemy.

Thanks to the phase quantum state and timestamp quantum state designed by Xu Yuan and the mixed-coded quantum direct communication system, the whole experiment went very smoothly.

During the process, one could clearly see the excited expressions on the faces of Pan Xianfeng and others.

Later on, I couldn't help but shout out loud.

"Success."

"We have successfully achieved quantum direct communication."

"No one in the world has been able to achieve direct quantum communication over such a long distance. It's simply amazing."

“I didn’t expect this new system to work so well, it’s really exciting.”

Xu Yuan listened to everyone's joyful voices, and although he didn't say anything, he felt relieved in his heart.

This experimental result shows that the hybrid coding communication system he designed based on phase quantum states and timestamp quantum states is indeed feasible and belongs to the correct research direction.

The thought stayed here, and he turned to Pan Xianfeng and said:
"Academician Pan."

"I think we can announce this good news to the world."

"You're right." Pan Xianfeng nodded with a smile.

……

It can be seen that the Quantum Innovation Institute does need a valuable scientific research result to prove its strength.

Therefore, on the day the experiment was successful, the Quantum Innovation Institute officially announced that it had successfully achieved long-distance quantum direct communication, breaking the world record.

Once the news spread, it caused a sensation across the entire Internet.

Because of the incident with the extreme ultraviolet lithography machine, netizens are also feeling angry.

Suddenly seeing that China has made significant progress in the field of quantum communications and that its technology has successfully taken the lead internationally, I undoubtedly feel excited and happy.

However, after discovering that the designer of this direct communication system was Xu Yuan, I was convinced that Xu Yuan did not participate in the research and development of the extreme ultraviolet lithography machine, and I felt somewhat regretful and lost.

After all, the progress in the field of quantum communications has once again proved one thing.

That is, as long as Xu Yuan is involved in a project, it will definitely bring surprises to everyone.

Under such circumstances, no one can predict what the final outcome of the research and development of domestic extreme ultraviolet lithography machines will be.

However, compared to the complex emotions of netizens, when the news spread overseas, although it shocked researchers in the quantum field, some people expressed happiness.

The most delighted person among them was undoubtedly Ames CEO Kajedi.

He was familiar with Xu Yuan's talent and strength, and knew that Xu Yuan had created many scientific miracles.

When he heard that Xu Yuan was involved in the research of extreme ultraviolet lithography machines, he was a little worried.

Now that the misunderstanding has been resolved, he can finally breathe a sigh of relief. As long as it doesn't affect the semiconductor industry, he doesn't care about other fields.
