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 during encryption or 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, only eight specific photons were captured ten times. This efficiency made the team numb.
These tyrants fully understand the pain of scumbags, and 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 must 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 hard on 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 emitted, we can choose to lock the photon first, and release the photon after burning the encrypted information.
Photons have no properties, so 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 then 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 arguing!"
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 actually 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, anyway, it is a failure, it is better to change the way of thinking and fail.
Just like that, 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 kind of physical resource. Due to the influence of 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 manufacturing department's technology, the equipment they needed was manufactured, otherwise it would be nothing but fantasy.
This is alsop; "Don't pull me, I'm not crazy, hahaha! I'm going to call home!"
"What's the call! The base station for quantum communication hasn't been built yet!"
"Are you confused? Did humans stop making phone calls before quantum communication came out?"
"right!"
Everyone has been suppressed for too long, and just wanted to vent their long-term depression of tackling difficult problems. When the three big cows saw this, they didn't stop them. Instead, they 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 a paradise for people who do research. 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 is our honor!"
This time, the cooperation between Changtian Technology and Xiaguo 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 do things that go too far, young people can't hold their breath." Pan Jian suggested at this time that 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 have a good rest."
When the three of them were inspecting the base, they passed the conference room, only to find that a large group of people were sleeping in this place. There are not enough dormitories here, so the gays can only sleep on the floor, and the female comrades sleep on the beds in the dormitory. Even in such an environment , These people all 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 rebuilt from the ground.
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 the information.
So, these are the questions to think about next.
? In other respects, the manufacture of related equipment must thoroughly understand the basic theory and convert it into production theory and production parameters. The experimental team must send people to watch it. From theoretical physics to production, applied physics is the key bridge.
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.
