Duan Zhu said: "Then if we don't go deep into the mountains, we'll go play near the snow mountain scenic area."
During the winter holidays in Bingcheng, the area near the snow mountain scenic area is crowded with tourists. There are tourists all day long. Tourists are becoming more and more enthusiastic about skiing, picking, and hiking in the snow-capped mountains. There are also many people coming to the farmhouse to eat, and there is no place for them unless they make a reservation in advance. There are attractions and places to visit everywhere. The villagers are even busier during the holidays, running ski resorts, developing greenhouse agricultural product picking, selling souvenirs, and operating B&Bs. From single ice and snow tourism to diversified expansion into culture, sports, B&Bs, and food. City owners have also stepped up efforts to protect the natural environment, promoted the integration of ecological resources and industry, and developed industries such as eco-tourism and snow bed and breakfasts.
Duan Zhu said: "Is the mapping network system similar to quantum communication?"
High-performance communications can be achieved through quantum effects. Compared with traditional communication methods, quantum communication has higher security and is not easily hindered during the transmission process. When the quantum state is not destroyed, it cannot be eavesdropped or copied during the transmission of information.
Compared with optical quantum communication, classical communication cannot be compared with its security and efficiency. In terms of security, quantum communication will never leak secrets. Firstly, the key of quantum encryption is random. Even if it is intercepted by a thief, the correct key cannot be obtained, so the information cannot be cracked. Secondly, it is in the hands of both parties in the communication. Two particles with an entangled state. If the quantum state of one particle changes, the quantum state of the other will change immediately. According to quantum theory, any macroscopic observation and interference will immediately change the quantum state and cause its collapse. , so the information obtained by the thief due to interference has been destroyed and is not the original information. In terms of efficiency, the unknown quantum state being transmitted will be in an entangled state before being measured, that is, it will represent multiple states at the same time.
"It's not the same as quantum communication," Hessing said.
Quantum communication is point-to-point communication, with a sending end and a receiving end. This communication mapping is communication between one area and another area, and it is one-way, that is, the sender has many points. There are many points on the receiving side. The sender sends it out, and the data reaches these points at the receiver. But the recipient cannot send the data back. There's a difference, it's multipoint-to-multipoint communication, and it's unidirectional.
In the original understanding, only one device can detect another or several devices. So this device is macroscopic and relatively large. But at the microscopic level, people are not familiar with how one particle detects another particle, or several particles, or multiple particles detect multiple particles.
Duan Zhu said: "Then this seems to be somewhat similar to the principle of gravity stone, electric distribution stone and other stones."
He Xin said: "Yes. We still have something to do. We will contact you when we get back."
Duan Zhu said: "Okay, you can do your business first. Let's take a stroll by ourselves. Don't worry about us."
He Xin, Xiang Yu, and Shunpin found Chu Qian first and said, "I recently went to the snowy mountains."
Chu Qian said: "You have to be careful. I heard that there are some strange beasts over there, and there are traps set by hunters."
He Xin said: "Who did you listen to?"
Chu Qian said: "I heard from Tan Pu and Tang Jian. They may have been to that place. Don't go there in the wilderness. Has the recent mapping network system been checked?"
He Xin said: "I checked. It's still the same."
Information from the entire galaxy may be projected to a certain area, and then people establish contact with this area. This area is called the transit pool. Just like a signal base station. That is to communicate with other places in the galaxy. Of course, we don’t dare to communicate yet, it is only used for detection and observation.
A large mapping network system was built in Ice City to receive information from the transfer pool. At first, it seemed like I had received some useful information. But garbled characters always appear later. I don’t know what caused the interference, but it can no longer be deciphered using the original method.
Shunfeng said: "It may also be that their communications use other methods of encoding."
Chu Qian said: "But some parts are still the original codes, and a large section in the middle has been cut off. If the important parts are not obtained, the original meaning of these codes will be very different, and the results will be completely wrong and opposite." conclusion."
He Xin, Xiang Yu and Shun Pin found Tan Pu.
Tan Pu said: "I have been there and seen some strange beasts, but I can't even name them. They might be snow leopards, lynxes, golden leopards, Siberian tigers, etc. That place is quite dangerous."
Snow leopard is the highest-altitude cat in its distribution area. The fur is thick and beautiful. The tail is the longest among cats. Lynx's tail is too short, like a rabbit's tail. It is relatively ferocious and can hunt prey much larger than itself. The leopard is a large cat second only to the Siberian tiger in size, and its number is very rare. The Siberian tiger, the largest and fattest of the cats, has thick fur and fat to fight the cold.
He Xin, Xiang Yu, and Shunpin found Tang Jian and said, "I found the device according to the location of the electromagnetic device you gave me. It is a slow light effect device. I also encountered a lot of solid ice."
Tang Jian said: "I have fallen into that trap before. I don't know if it was man-made."
He Xin, Xiang Yu and Shunpin found Feng Jichao.
Feng Jichao said: "I got the news from the villagers near the scenic area, saying that it is more dangerous in the deep mountains. I went skiing there two months ago."
He Yushen said: "I heard about it from Researcher Li. He has retired now."
He Yushen said: "Some researchers have never reached the conclusions they wanted in their entire lives. But they have been working diligently, step by step, and done things in a down-to-earth manner, and they have made some achievements. They do not seek brilliant results, but they seek a clear conscience." "
"Like the photon pillar."
"I always thought that he would have a long time to retire, and he should still be able to do a lot of things. But time flies by so fast. The career is over, and what he was supposed to do is actually left to us."
For metals, no electric field can be formed inside at all, so it is difficult to generate electromagnetic waves inside the metal. It is extremely difficult for light to enter the metal after encountering it, and most of it will be reflected out. Objects with strong reflection ability of a certain monochromatic light will have a corresponding strong reflection effect. From the outside, these objects are also opaque or have poor transparency.
When the photons of light in a medium are absorbed by atoms in the medium, the electrons will be excited to a higher energy level, and there is a certain probability that photons will be released again. If the energy loss of the light is small , can penetrate this object.
Then, several people find a room to discuss their opinions.
He Xin said: "Look, different people have different concerns."
Instantaneous said: "I feel like they are just rambling and changing the topic?"
Chu Qian is talking about mapping network communication devices. Tan Pu is talking about snow animals. Tang Jian is talking about traps. Feng Jichao is talking about the villagers in the snow. He Yushen was talking about retired Researcher Li.
