The moment the experiment started, everyone held their breath.

However, the miracle did not happen, the receiving device did not catch the specific photon, and it is not known whether there was a problem in the encryption or the reception.

"It may also be that there is a problem with the quantum channel." Lu Yang added, Guo Can rubbed his temples, and his brain buzzed. Doesn't this mean that there may be problems with all links?

He also said that he wanted to do some kind of thorough teleportation. It is impossible to improve the efficiency of the quantum distribution key now. How about playing?

After three days of experiments and repeated tens of thousands of experiments, specific photons were captured ten times and eight times. This efficiency made the team numb.

These tyrants fully understand the pain of scumbags, even though they have given technical explanations, why can't they solve it? nonsense!

There are still specific proof steps for the Riemann conjecture. How many people can understand it?

If the basic knowledge is not achieved, it has to be verified step by step.

Chen Xiao gave technology. The problem is that once it comes to the improvement of technology, it is an expansion of the overall knowledge framework. It is enough to work **** the modern science test with a score of 70. If it is above 90, every point is very difficult, and sometimes it is doubled. Efforts can only improve 0.001 points.

And this kind of leap, even if there is information provided by the system, you still have to try hard. This is a process of mastering the technology. Only by doing this can all the supporting facilities catch up.

"Everyone, please stop, I think this method is a bit unreliable. I have thought of a method, but I don't know if it will work."

"Hurry up, can it be worse than now? We haven't even crossed the threshold."

"Since the photon cannot be caught after it is launched, we can choose to lock the photon first, and release the photon after burning the encrypted information.

Photons have no properties, and there is no way to control the speed at all. Unless the gravitational field like a black hole is involved with each other, it may be possible to control the speed, but we can't make a black hole. "

"Throw it away! Wouldn't it be better to just connect directly to the optical fiber? We're still doing research! Besides, if there are black holes, wouldn't it interfere with quantum entanglement? Did you buy this doctoral degree?"

"How can you curse people! If there are multiple black holes, maybe you can slow down and recover, and the effects will be balanced! No! I didn't say anything about black holes."

"Waste time to come up with this method? Isn't it relying on optical fibers? Should the manufacturing department make an optical fiber for you that can only accommodate one photon?"

"Stop making noise!"

Scientific research is not always polite, modest, and reasonable as everyone imagines. If you are impatient, you can really get started. Everyone can’t come up with a clue after arguing. If the basic theory here can’t be worked out, the mobile phone chip can’t help Design and mass production, the quantum team is under a lot of pressure.

The way everyone thought before was to directly emit point-to-point lasers. As long as the laser is concentrated enough, the impact on the real world is small enough.

But it's not. If there is an obstruction during the launch, then a hammer will be received.

It's not that this idea is completely useless, at least it can be used in emergency contact with certain confidential units, but it can only be used as a last resort. This method consumes a lot of power instantaneously, and the equipment is complicated. It is not as practical as sending a specific password by radio.

For civilian use, we still have to think of a better way.

"Leave classical information aside and focus on quantum entanglement! We're going to skip ahead, and the original path is a dead end! After all, ten-photon entanglement has been realized now. We might as well start here!" After Guo Can didn't sleep for a few days It was finally a decision.

The reason for making this decision is that the technology required by the data is too different from the existing production content.

Everyone is really numb, it is a failure anyway, it is better to change the way of thinking and fail.

In this way, this group of people began to conduct experiments in retreat, no longer involving traditional optical fiber transmission, but engaging in real photon entanglement!

The real difficulty today is that entangled states are a physical resource, and affected by laboratory conditions and environmental noise, it is difficult to produce ones with the largest entangled states. The pure entangled state will also degenerate into a mixed entangled state under the influence of the environment, and in this way, the information will be distorted. In this way, the mixed entanglement has to be transformed into a pure entanglement state, which is called entanglement purification technology.

After several months of hard work, this group of people finally came up with the theory at the end of 2023. Thanks to the improvement of the technology of the manufacturing department, the equipment they needed was manufactured, otherwise it would be nothing but fantasy.

This is why Yang Ming called for attention to skilled workers in his academic report.

If you can't figure it out, you will have to suffocate to death with urine. If the manufacturing technology improves fast enough, this feasibility theory will come out in the middle of the year, which shows the importance of manufacturing.

The improvement of the manufacturing industry also requires the improvement of basic theories, and then all production departments can only be achieved by interdisciplinary improvement. If a part has a weakness, the upper limit depends on how low the weakness is.

The Changtian Institute of Science and Technology and the Xiaguo Academy of Sciences jointly published a related paper. This paper is not public, and only experts from related disciplines and manufacturing departments have read it.

Firstly, this is not a complete theory, and can only be verified after a complete set of equipment is in place. On the other hand, this is a state secret, related to communication security, and cannot be made public.

The base station was only built in early 2024. Before that, the joint team continued to optimize the experimental process and perfect the theory in the laboratory. After these days of continuous improvement, the team is still very nervous about the experimental results in the actual environment.

The day finally came to the day of the experiment. One base station was in the Taklamakan Desert, and the other base station was in Venezuela on the other side of the world. The equipment was transported secretly, and Venezuela would probably not be opposed even if it was told.

There were still three minutes left in the experiment, and all the people held their breaths. After suffering for so long, I finally ushered in the final exam today. If I failed, I really didn't know how to clean up my mood before doing research.

"Huh! Huh!" The wind in the Taklimakan Desert is very noisy today, and the sand and dust are surging, like waves, constantly hitting the equipment. The base station is like a lighthouse buoy in the rough sea, it seems that it will be blown down at any time.

In Venezuela, it happened to be the end of the summer season, when the rainfall in the tropical rainforest climate was the heaviest. The cloud layer activities during this period were very complicated. On the day of the experiment, there were lightning and thunder, and the sky was as dark as the end of the world.

Such harsh conditions made everyone feel uneasy, and such bad weather had the greatest impact on the experiment. But from another point of view, if the experiment can be successful under such conditions, it will prove that the technology is reliable, and it will enter commercial application very quickly.

"The experiment has begun! I hope everything will be successful!" Guo Can was wrapped in a cotton coat and stood in the wind and sand. He didn't want to stand inside and wait for the results of the experiment. He didn't have the courage to read it by himself, but waited for his staff to inform him.

Pan Jian and Lu Yang didn't go in either, they would rather listen to the loud sound of wind and sand, because this experiment is too important, enough to win the Nobel Prize in Physics, this is actually not important, the most important thing is that they will start a brand new era!

"Quantum computer enabled, quantum algorithm ready!"

"Quantum encoding in progress."

"The ion trap is well prepared, and the multi-ion entanglement state is successfully realized!"

"The degree of entanglement reaches the standard."

The inquiry message has been sent, and the matter has come to an end, and the rest is waiting for the news from Venezuela.

Normally, the time required for on-site coding is very short, and it only needs to manually answer specific questions. But these five seconds are like five years to everyone.

Five seconds later, news from Venezuela came back: "Keep to the right!" Everyone was jubilant.

Because the question is: "In Xiaguo, do pedestrians and vehicles keep to the left or to the right?"

"Don't worry! Venezuela is still asking questions!" The person in charge of the scene held back his joy.

The news from over there quickly spread: "Your mother and wife fell into the water at the same time, who do you save first?"

Obviously, Venezuela is also cheering, and it has brought up such a silly problem.

"Respond to them! We succeeded!" The person in charge ran out while shouting, the sound here could not be heard inside the wind and sand, and the three masters were looking at the base station with their backs to the control center.

"We succeeded! We succeeded!" The person in charge of the scene ran to the front of the three of them, roaring hoarsely. When he opened his mouth, the wind and sand entered his mouth, but his expression had already told the result to the three of them.

This is quantum communication in an absolute sense. It does not rely on satellites, but only on the principle of entanglement. The equipment sends and receives entanglement pairs to convert them into specific codes, and the codes are then converted into text, language, pictures and other information that humans can understand.

Three men in their forties hugged each other, as happy as children. When they returned to the control room, the people inside were almost crazy.

"Hahaha! I finally got my hair out! I've lost a lot of hair!"

"Let the people in the biology lab give us some drugs for hair growth! Aren't they amazing? They have the ability to treat baldness! What kind of cell is omnipotent! We are quantum science! Ah!"

"Don't pull me, I'm not crazy, hahaha! I'm going to call home!"

"What call! The base station for quantum communication has not been built yet!"

"Are you confused? Did humans stop making phone calls before quantum communication came out?"

"right!"

Everyone suppressed it for too long, and just wanted to vent their long-term depression of tackling difficult problems. Seeing this, the three big cows didn't stop them, but found a quieter place to drink together.

"Actually, we have heard of your name a long time ago. If you come to the Academy of Sciences, you will definitely become an academician." After drinking for three rounds, Pan Jian looked at Guo Can with sympathy.

Guo Can smiled: "I know, but if you want to do research, as long as you have the research conditions, it doesn't matter where you go?"

"Actually, I want to come to Changtian Technology. The good ideas here come one after another, and the good technologies keep coming out. It's heaven for people who do research to stay here. Even if they are not in their own related fields, it's good to have a look. .” Lu Yang said very directly, he would not turn corners.

"Don't, don't, don't talk about this matter, lest you say I poach a corner. Haha!" Guo Can waved his hand quickly, he can't decide this matter, "One thing is certain, our cooperation will be more and more in the future , because there are still not enough people from Changtian Technology alone." The number of talents is also a very important factor, and you two must not be stingy when looking for borrowers in the future! "

"That's our pleasure!"

This time, the cooperation between Changtian Technology and Xia Guo Academy of Sciences has been very in-depth, to the extent of sharing theories, and this has also brought great success.

"Look at the brats! Don't let them go too far, young people can't hold their breath." Pan Jian suggested at this time when he was almost done.

When the three of them arrived in the control room, it was very quiet inside. Only a few people were on duty, and the rest were gone.

"Where are the others? Where did you go to celebrate?" Guo Can asked subconsciously.

"Professor Guo, everyone is looking for a place to rest. Many people have been up for more than ten days without much sleep. Some people spontaneously followed when they should rest. Do you want me to call them? Is there something urgent to deal with? "The employee on duty explained a little bit.

"No, let them rest well."

When the three of them were inspecting the base ~lightnovelpub.net~ they passed the meeting room, only to find that there were a lot of people sleeping here and there. There are not enough dormitories here, so the gays can only sleep on the floor, and the lesbians sleep in the dormitories. The beds, even in such an environment, these people slept soundly.

"Notify them of a three-day holiday, and let them arrange their own shifts. What do you think, Academician Pan?"

"Agreed! The children have really worked hard."

Chen Xiao was very happy when he heard the news of the successful practice, and gave him a generous scientific research bonus. The next step is to plan the construction of the base station.

Quantum communication also requires a base station, whose function is to distribute entangled photons, convert specific codes, and realize communication.

Moreover, the computing power of each base station is limited. To achieve universal communication, there must be enough base stations, or the computing power must be improved.

The initial idea is to take over the operator's base station and transform it. If the transformation is too difficult, it can only be built on the ground and rebuilt.

The next task of the experimental team is still very heavy, and it is not easy to improve the computing power. How much information can a photon carry? In principle, if there are enough entangled states between the base station and the mobile phone, if they are complex enough, the most information can be processed in the shortest time. The difference is the same as one spelling in Morse code and the other expressing directly in words.

Once there are more entangled states between the quantum chip of the mobile phone and the base station, it is possible to interfere with each other and affect the fidelity of information.

So, these are the questions to think about next.

In other respects, the manufacture of related equipment must thoroughly understand basic theories and transform them into production theories and production parameters. The experimental team must send people to watch over them. Applied physics is the key bridge from theoretical physics to production.

However, Chen Xiao is very confident that it will be resolved soon. The first step has already been taken, and at least the road ahead has a direction.
