At 8 o'clock in the morning, Liu Qingquan appeared in his office on time, with a habitual smile on his face, so that everyone knows that the boss is in a good mood, and hastened to report any troublesome things.

"Hey, President Cai, please come to my office for trouble." Liu Qingquan remembered the deal with the three families as soon as he arrived at the office, and quickly called Cai Jian to discuss with him.

Within a few minutes, Cai Jian came to Liu Qingquan's office. Liu Qingquan immediately got up and asked his secretary Deng Yujie to have tea.

"Mr. Liu, I don't know what happened to you when you came to me?" Cai Jian at work was obviously a workaholic. He was unwilling to waste any time and asked directly.

"That's it. Regarding this supplier bidding, when I went to the imperial capital yesterday, I reached an agreement with the three families of Qian, Li, and Rong. The supplier's spare parts were divided into three families, in exchange for Their support for the company ... "For Cai Jian, Liu Qingquan did not conceal anything, and explained the transaction to Cai Jian in detail.

"Um ~~ I know how to do it. I was still worried about President Liu. Now it seems redundant. There are three families to be the backers. The company will have a lot less trouble in the future, but this relationship is not very reliable. "In the future, there will be really big difficulties. President Liu still needs to make preparations early." Cai Jian nodded after listening, and at the same time he expressed his thoughts.

"I also know that, in fact, these big families are simply predators that can't feed themselves, one by one, they can't wait to swallow the company directly, but now it seems that the country is engaged in transformation, and we want to set up high-tech benchmarking companies, and our company is just Target, so we only have a lot of trouble now. What I do now is to prepare for the future. The issue of supplier share is just the contact and cooperation that has just begun. In the future, more people will be tied to our interests. "On the chain," Liu Qingquan nodded, and told his thoughts and plans.

"Well, Mr. Liu has his own plans. I don't know if Mr. Liu has time. Can you take the time to attend the supplier conference in a few days?" Cai Jian didn't have too many plans for the boss's deeper plans. Ask. As a subordinate, you should know your status. The boss who should know will tell you. Do n’t ask too much if you do n’t.

"Let ’s look at it at that time. I do n’t think there is much time. These days, we are already studying anti-gravity rockets. Our flying cars will be launched on a large scale soon. This is not possible without satellite navigation at all. Many places rely on radar alone. Not covered, and it is not accurate, we must have our own global positioning and navigation system! "Liu Qingquan thought for a while.

"Mr. Liu, you don't have to worry too much. We can install navigation equipment on the flying car first, and then use it after our global positioning and navigation system is built. In a short time, we can only follow the old method." Cai Jian I thought about it and proposed.

As soon as Liu Qingquan heard it, his eyes lighted up, and he quickly wrote it down in a notebook. This suggestion was very useful. Originally, he planned to complete it within this month. He launched a part by himself, commissioned a part of the international commission, etc. The positioning and navigation of several important areas came. As soon as Cai Jian proposed, there was no need to worry too much, and time would be relatively abundant.

"That's a good suggestion! Go back and talk to the research institute first, first research the communication equipment to install on the flying car." Liu Qingquan praised while recording.

"I just talked casually, I didn't expect it to be really useful. I wonder if President Liu had any other orders?" Cai Jian smiled.

"No more, please go busy!" Liu Qingquan smiled and said that there are not so many courtesies between the two people, after all, it is the relationship between superiors and subordinates, but also in the workplace and time.

"Okay, then I'm going to get busy first. You can tell me to call me directly." Cai Jian is also very busy. The company has a lot of daily affairs. He is not like Liu Qingquan who can only focus on big things. Every detail needs to be paid attention to. After all, how high the salary is, at least it must be worthy of its performance.

Liu Qingquan nodded, took the documents on the table and looked up.

...

There are not many documents that Liu Qingquan needs to check last, but they are often very important things. Liu Qingquan will take a very serious look at these things. Many details even have to call to ask one by one, and finally feel that there is no problem. Only when the document is signed, some people who have different opinions will also give instructions. It has never been directly rejected. This is also a respect for Liu Qingquan's employees, and it is also his own consideration. After all, in addition to his research I'm a little bit positive on the other side, and I'm totally innocent in other respects. Listening to your subordinates will definitely not be wrong. Even if you go back wrong and then follow your own opinion, it will appear to be more level.

Soon after finishing several things, Liu Qingquan came to the institute.

The daily affairs of the academy are formalized after the reform. The research work is very boring. Many times, it is difficult to produce repetitive tasks over the years. Only those who really like research will fall in love with such work.

Liu Qingquan came to the Institute of Information Science and Technology. He remembers that a newcomer has performed very well. He was rated as the first-level mid-level in this reform. He is a graduate of Zhejiang University ’s communications major. His name is Zhou Jingbo, and he has considerable experience in communications He has a solid foundation, a solid foundation, and is very passionate and innovative.

As a middle-level scientific researcher, Zhou Jingbo has the right to set up his own research group. At this time, he is carrying a few people who are also interested in communication technology research. He is holding a wire to dry the same thing, and one next to it. Weird, humble signal-receiving equipment is ringing.

"Jing Bo, what are you doing?" Liu Qingquan came over and asked with a smile.

"Boss, you are here. We have recently been studying the electromagnetic wave receiving technology and have achieved good results. We will soon be able to report to the Academy." Slowly followed by the boss Liu Qingquan.

The electromagnetic wave technology just mentioned by Zhou Jingbo is the main technology of modern communication. Basically all communications now rely on electromagnetic wave technology. It has extremely superior characteristics. Compared with wired communication technology, it does not need to set up communication lines. Affected by the communication distance and other advantages.

This technology is the mainstream technology of today's communication. The mobile phone that everyone uses is electromagnetic wave technology. The communication company uses the large-scale building signal tower on the ground to receive the transmitted electromagnetic wave signal to achieve mobile phone communication, not the satellite signal that everyone imagines. .

It is very interesting that the inventor of electromagnetic wave technology does not have a unified and universally recognized scientist. In the United Kingdom, Maxwell was regarded as the pioneer of radio, thinking that he first pointed out the existence of electromagnetic waves. In the United States, some people think that De Forest is the father of radio because he invented the transistor, which is a radio communication device. Heart; in Russia, only the husband is recognized as the founder of radio communications; in the eyes of Western scientists, Italian Marconi was the inventor of radio communications, and he was awarded the Nobel Prize in Physics; in Germany, Hertz is considered to be The founder of radio, because he first proved the existence of electromagnetic waves, and the unit of the frequency of electromagnetic waves was named after his first name; who invented radio communication?

Compared to others, this scientific achievement is too much to say ...

Electromagnetic wave communication technology also has its own natural advantages, but now more and more scientific research surface, electromagnetic wave technology has a very great impact on living things, and will cause harm to the human body.

Increasingly dense electromagnetic wave signal transmitting and receiving towers, especially high-power electromagnetic transmitting stations, broadcasting transmitting stations, ultra-high voltage transmission lines for transmitting electricity, urban transportation systems, and home computers, televisions, microwave ovens, electromagnetic cookers, mobile phones, etc. Will cause electromagnetic pollution of the environment.

If you stay in it for a long time, it will cause harm to the human body, and some of the injuries deserve everyone's attention and attention.

Electromagnetic waves are most harmful to the human body in the three aspects of thermal effects, non-thermal effects and accumulation effects, causing the body to be disordered, causing headaches, dizziness, insomnia, forgetfulness and other neurasthenia symptoms; make people weak, loss of appetite, irritability; irritability; Disturb the body's thermal regulation system, leading to increased heart rate, increased or decreased blood pressure, respiratory disturbances, and decreased white blood cells; it plays a role in contributing to the occurrence and deterioration of cardiovascular disease.

Women, especially pregnant women, and children are greatly affected by electromagnetic waves, and the damage they cause is also more serious.

...

This time Liu Qingquan is going to come up with a more advanced communication technology for Zhou Jingbo to study. This technology is called quantum communication technology.

Quantum communication refers to a new type of communication using the quantum entanglement effect for information transmission.

Quantum communication is a new type of interdisciplinary developed in recent years, and it is a new research area combining quantum theory and information theory. Quantum communication mainly involves: quantum cryptographic communication, quantum remote transmission, and quantum dense coding. Recently, this discipline has gradually moved from theory to experiment.

Compared with the traditional electromagnetic wave communication technology, the traditional technology is far from comparable in terms of efficiency and security.

Quantum communication will never “leak”. Its quantum encryption key is random. Even if it is intercepted by a stealer, the correct key cannot be obtained, so the information cannot be cracked. Second, there is entanglement in the hands of both parties to the communication. Two particles of a state, the quantum state of one particle changes, and the quantum state of the other will change immediately. According to quantum theory, any macro observation and interference in the macro will immediately change the quantum state and cause it to collapse. The information obtained by the thief due to interference has been destroyed, not the original information.

In terms of efficiency, the transmitted unknown quantum state will be in an entangled state before being measured, that is, it represents multiple states at the same time. For example, a quantum state can represent two numbers, 0 and 1, at the same time. 128 states or 128 numbers: 0 ~ 127. Such a transmission of optical quantum communication is equivalent to 128 times of the classical communication method. It can be imagined that if the transmission bandwidth is 64-bit or higher, the difference in efficiency will be an astonishing 2 and higher!
