When I am reborn, I just want to be a top student

No one expected that those who came to inspect the rocket launch center would discover a completely new business.

Although the money earned from advertising is considerable, it is not important to Galaxy Technology at present.

The reason why everyone was so excited and enthusiastic was for another reason.

That is, when Galaxy Technology actually achieves this.

Therefore, Galaxy Aerospace's position was completely set.

No one will look down on GalaxySpace just because it is a private aerospace company.

At the same time, developing new business areas will also add an industry point to GalaxySpace's portfolio.

"Let advertising revenue become fuel for space exploration. Instead of letting them spend their advertising revenue on television and the internet, it would be better to turn it into funds for the development of the space industry."

"I hope that in the future, people will think of our actions in this way."

"When advertising slogans appeared on the moon, our forerunners had already built a wormhole between consumerism and scientific exploration, which was far more effective in advancing civilization than rockets themselves."

Upon hearing Wang Donglai's meaningful words, everyone present became serious.

They naturally understood the meaning behind Wang Donglai's words.

Advertising on rocket launches is merely a means, not a means to an end.

The purpose is to allocate more funds to the development of the aerospace industry and to attract more attention to it.

An industry can only develop when more people pay attention to it, more people participate in it, and more money flows in.

Relying solely on Galaxy Technology is far from enough.

Even with the national team, there are still some shortcomings.

"Clap clap clap..."

Thunderous applause erupted, and everyone spontaneously stood up, looking at Wang Donglai with heartfelt admiration.

Yang Anchao and Wang Hongtao were particularly inspired.

The two had worked in the aerospace system for many years and had a deep friendship.

He has made the aerospace industry his lifelong career pursuit.

Otherwise, I wouldn't have come to Galaxy Technology.

……

The staff at the Galaxy Rocket Launch Center had other expectations for Wang Donglai's arrival.

That was a discussion about technology.

"Chief Engineer Yang, please report on your current research and development progress!"

Wang Donglai didn't let Yang Anchao and the others bring it up first; he took the initiative to do so himself.

Yang Anchao's face lit up with joy, and he immediately began to report: "Chairman, based on the quantum materials we have developed before, we have conducted a large number of experiments. The preliminary technical direction we have determined is to use quantum repeaters to establish a long-distance quantum channel and use the quantum properties of the established quantum channel to achieve secure quantum signal transmission."

"In this regard, a paper from the University of Science and Technology of China inspired us. Using a parametric downconversion light source, it realized the nested entanglement purification and second-order entanglement exchange process in a quantum repeater based on linear optics, providing forward-looking technical guidance for realizing a scalable linear optical quantum repeater based on an atom system."

These words might be difficult for non-professionals to understand.

However, Wang Donglai is naturally not a problem.

He said with a hint of annoyance, "Chief Engineer Yang, I think I understand what you mean."

"So you want me to help solve the problem of how to maintain the original characteristics of the quantum channel in a quantum repeater, right?"

Yang Anchao's face also showed a hint of embarrassment, but more than that, it was a sense of self-righteousness.

"Chairman, everyone knows your research capabilities. I'm afraid no one else could have done this research."

"If this were left to us, we don't know how much time and resources it would take to solve this problem alone."

"Solving this technical challenge as soon as possible will be of great benefit to our subsequent space exploration."

Wang Donglai also understood this principle.

Whether it's quantum communication technology, quantum materials, or quantum computers.

Actually, this isn't the kind of technology we should have at this time.

In many ways, it has already exceeded the scope of the curriculum.

Wang Donglai believes that even now, with the quantum computer prototype developed by China, there are still very few people in the country who can fully understand the principles and technology behind it.

Wang Donglai had long known that Galaxy Technology's R&D team could not possibly develop a quantum repeater.

However, he could not explain it directly.

After all, human nature is complex.

Only after they've encountered problems on their own will they realize how difficult the technique is.

In this way, only by overcoming the technical difficulties ourselves can we obtain the greatest benefits, which is also good for the stability of the company.

People who are truly skilled in technology rarely idolize others because of money.

However, if you surpass it technically, it can be done very easily.

That's exactly what Wang Donglai was planning!
Even if you don't have any results yet, you should at least have research ideas and solutions for filing a case!

Yang Anchao nodded quickly and said, "Chairman, according to the current mainstream thinking, we also agree that quantum repeaters contain CONT operations. However, the problem lies here. Currently, we have not yet realized a CONT channel that can achieve an error of no more than a few percent and be used for long-distance quantum channels."

"The solution is to use only linear optical devices, with entangled photon pairs as the transmission channel for quantum information. The purpose of using quantum repeaters is to increase the interaction distance of high-quality entangled photon pairs."

"By purifying and exchanging the entanglement of short-range entangled photon pairs, we can obtain long-range entangled photon pairs with high entanglement. This allows us to establish long-distance quantum channels."

"..."

As Yang Anchao spoke, Wang Donglai nodded in agreement.

From Yang Anchao's answer, he could tell that Yang Anchao and his research team had indeed put in a lot of effort.

These things cannot be explained so fluently without thorough and in-depth study.

After Yang Anchao finished speaking, Wang Donglai said, "I'll give you a general technical idea for the quantum repeater. Now let's talk about the Tiangou lunar probe."

Yang Anchao's face lit up with joy, knowing that as long as Wang Donglai agreed, it meant that the problem of quantum repeaters would be solved.

Yang Anchao had complete faith in Wang Donglai's research capabilities. Relieved, he began to introduce the 'Tiangou' lunar probe.

"Thanks to the technical support from the China Aerospace Science and Technology Corporation, we obtained a lot of crucial data and information from the Tiangou lunar probe."

"According to estimates, the Tiangou robot is designed to have a lifespan of eight years or more and can operate in a six-month cycle of day and night on the moon."

"It is 2.1 meters long, 1.8 meters wide, and 1.5 meters high, with a net weight of 280 kg. It adopts a foldable and expandable structure, and its launch volume is less than one square meter."

"Given the unknown lunar environment, the addition of the short-duration flight function was abandoned. Instead, an active suspension chassis with a maximum slope of 35 degrees was adopted. It features a hybrid drive system of four-legged power and wheels, and a design to resist lunar dust, preventing dust from entering internal components and affecting operation."

"In terms of communication capability design, we have implemented dual backups of the Deep Space Network and the Queqiao relay satellite, with an uplink speed of 2Mbps and a downlink speed of 10Mbps in the X-band. If the chairman can develop a quantum repeater sooner, we can also try quantum communication technology."

"In terms of positioning accuracy, we have received the greatest support from above. With the addition of the current BeiDou system, the real-time RTK positioning error is only about 0.5 meters."

"In terms of energy systems, we have also exchanged and cooperated with the top photovoltaic teams in China. We have adopted a triple-junction gallium arsenide solar panel solution with an unfolded area of ​​12 square meters. The photoelectric efficiency on the moon is about 31.7%, and it has electrostatic automatic dust removal. It generates 9.7 kWh of electricity during lunar day and night."

"The battery pack is divided into two parts. One part is a special isotope battery manufactured using a special process, with a power of 260W, which provides a backup power supply and can withstand continuous power supply in low-temperature environments exceeding -180 degrees Celsius."

"The other part uses the Xuanwu battery pack, which achieves an energy density of 1600Wh/kg without sparing materials and processes, has a cycle life of more than 4000 times, uses phase change material for insulation, and has an operating temperature range of -70℃ to 55℃."

"In terms of battery energy management, we have applied artificial intelligence technology to implement an adaptive power-saving mode, which puts the battery into hibernation during rest periods, with a power consumption of less than 15W."

"On the Tiangou detector, we are equipped with a laser-induced breakdown spectrometer and a gamma-ray spectrometer, which can detect down to a depth of 1 meter and identify elements with an accuracy of ±10 ppm. As a geological exploration tool, it can achieve preliminary objectives."

"In terms of meteorological monitoring, it is equipped with a micro weather station for temperature, pressure and radiation detection, as well as a lunar dust counter with an operating temperature of -200℃ to 130℃ and a radiation detection accuracy of 99.7%."

"In terms of water ice search, it is equipped with a neutron water ice detection radar and an infrared imaging spectrometer, which can detect water ice in polar shadow pits with an accuracy of 100g/t."

"The detection of this surface structure of the moon is carried out using ultra-wideband ground-penetrating radar, which can penetrate to a depth of 800m and has a resolution of 0.4m."

"To protect against the extreme heat on the moon, a silicon carbide ceramic heat shield and liquid cooling circuit are used to keep the temperature control power consumption below 35W."

"Similarly, we also used multi-layer aerogel insulation and radioactive isotope electric heating to address the extreme low temperatures on the moon."

"As for dust intrusion on the moon, our solution is a magnetic repulsion coating plus electrostatic sealing."

"Finally, regarding the particle impact caused by micrometeoroids that may occur in the space environment, we use Kevlar and titanium alloy composite armor, which, after testing, can withstand the impact of particles smaller than 2cm at space speeds."

"Based on a comparison with existing lunar probe data, the Tiangou spacecraft's energy system is four times more powerful than that of Chang'e-4."

"The depth of the probe is 15 times that of the March 3."

"Its lifespan is twice that of the Curiosity rover."

"Finally, regarding the development cost of the 'Tiangou' lunar lander, the cash cost alone was thirty million."

"This does not include the strong support from the two major aerospace technology groups and related units."

"However, in return, we will share the lunar soil maps and weather models we obtained through the Tiangou spacecraft."

Wang Donglai had already seen this data.

Wang Dong is probably even more familiar with this data than Yang Anchao is.

The reason for having Yang Anchao give the report was to assess his work performance.

If Yang Anchao, as the person in charge, cannot even provide detailed data on such an important lunar probe, then it means that his work is inadequate.

Fortunately, this did not happen.

After Yang Anchao finished speaking, Wang Donglai smiled and said, "The Tiangou lunar probe is just the beginning. Since ancient times, we have had many wonderful fantasies about the moon."

"With modern technology developed to this extent, we can reach for the moon in the sky and capture turtles in the five oceans. We have a heavy responsibility on our shoulders."

"By using a dual-engine approach of photovoltaics and basalt cells to break through energy bottlenecks and achieve long-term commercial exploration, we will open a new chapter in lunar exploration."

"The more we learn about the moon and the more information we have, the greater the benefits will be for our later development of the moon."

"Therefore, this lunar exploration is of great significance not only to us, but also to the development of our country's space program."

Wang Donglai frequently mentions these things to his senior executives so that everyone can understand the importance of technology and gain a deeper understanding of Galaxy Technology's mission.

Those who can accept this are the partners Wang Donglai needs.

Those who disagree with this approach are naturally not partners.

After learning this information, Wang Donglai ended the meeting.

If Wa weren't still unable to truly demonstrate her abilities, Wang Donglai wouldn't have needed to do this at all.

Therefore, it is quite necessary to meet and hold meetings with Galaxy Technology's senior executives from time to time.

Compared to other CEOs, Wang Donglai holds very few meetings.

After the meeting ended, Wang Donglai immediately got busy.

Since Yang Anchao brought up the issue of quantum repeaters, Wang Donglai naturally had to help resolve it.

With products like the Xuanwu battery already developed, adding another quantum repeater to completely overcome the final hurdle in quantum communication technology is nothing special.

With this in mind, Wang Donglai immediately began research and development.

Now that Wang Donglai has reached this level, developing these technologies, while not exactly effortless, is certainly not too difficult.

Moreover, Wang Donglai already had some technical reserves in quantum repeaters.

At this moment, picking it up again and starting research and development won't take much time at all.

Didn't sleep all night.

The next morning, Wang Donglai handed a USB drive to Yang Anchao.

"This is the CONT operation that I wrote out in one night. You can test it. If there are any problems, you can optimize and iterate according to the comments I wrote, and that should be about right."

"I've only completed a rough outline; you'll still need to refine some of the details yourselves."

Yang Anchao's eyes widened immediately as he took the USB drive from Wang Donglai.

He never expected Wang Donglai to be so fast.

The development of quantum repeaters can be completed in just one night.

Although Yang Anchao was aware of Wang Donglai's research and development capabilities and had great confidence in them.

However, such a short time and such strong R&D capabilities still exceeded his expectations. (End of Chapter)
