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 in his subordinates knew that the boss was in a good mood, and he hurried up and reported any troublesome things.

Hey, Mr. Cai, please come to my office. As soon as Liu Qingquan arrived at the office, he remembered the transaction with the three families, and hurriedly called Cai Jian over to discuss it with him.

A few minutes later, Cai Jian came to Liu Qingquan's office, Liu Qingquan got up quickly and called the secretary Deng Yujie to serve tea.

Mr. Liu, I don't know why you are looking for me? Cai Jian at work was obviously a workaholic, and he didn't want to waste any time, so he asked directly.

That's right, 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, and the parts of the industrial and supplier parts will be divided among the three families in exchange for Their support for the company... Regarding Cai Jian, Liu Qingquan did not hide anything, and told Cai Jian the details of the transaction.

Well~~ I know how to do it. I was worried about you, Mr. Liu. Now it seems to be superfluous. With those three families as the backing, the company will have a lot less trouble in the future, but this relationship is still not very reliable. , there are really big difficulties in the future, Mr. Liu still has to prepare early. Cai Jian nodded after listening, and at the same time, he spoke out his thoughts.

I also know that in fact, these big families are simply predators who can't get enough food, and they can't wait to swallow the company directly, but now it seems that the country is undergoing transformation and wants to establish a high-tech benchmark enterprise, and our company just happens to be Therefore, we have less trouble now. What I do now is to prepare for the future. The issue of supplier share is just the beginning of contact and cooperation. In the future, we will tie more people to our interests. It's up to the chain. Liu Qingquan nodded and expressed his thoughts and plans.

Well~ Mr. Liu has his own plans. I don't know if Mr. Liu has time. Can you make time to attend the supplier conference in a few days? Cai Jian didn't have too much of the boss's deeper plans. Go ask, as a subordinate, you should know your own status. The boss who should know will tell you, and don't ask too much about what you shouldn't know.

Let's see when the time comes. I guess I don't have much time. I've been working on anti-gravity rockets these days, and our flying cars will be launched on a large scale soon. This is impossible without satellite navigation. Radar alone is a lot of work. The coverage is not available, and it is not accurate, we must have our own GPS navigation system! Liu Qingquan thought for a while and said.

Mr. Liu, you don't need to worry too much. We can install navigation equipment on the flying car first, and we can use it directly after our GPS navigation system is built. In a short time, we can only follow the old method. Cai Jian After thinking about it, he suggested.

When Liu Qingquan heard this, his eyes lit up, and he quickly recorded it in a notebook. This suggestion is very useful. Originally, he planned to complete it within this month. With the positioning and navigation of several important areas, when Cai Jian proposed, he didn't need to be too anxious at all, and he would have a lot more time.

This is a good suggestion! Go back and talk to the research institute first, and first develop communication equipment to install on the flying car. Liu Qingquan praised while recording.

I just said it casually. I didn't expect it to be useful. Do you have any other orders from President Liu? Cai Jian smiled.

No, go get busy! Liu Qingquan said with a smile, there is not so much etiquette between the two now, after all, it is the relationship between superiors and subordinates, and it is in the workplace and time.

Okay, then I'll go to work first. You can call me directly if you have any instructions. Cai Jian was also very busy.

There are many daily things in the company. Unlike Liu Qingquan, he can only focus on major events. He needs to pay attention to every detail of the company's daily life.

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

…….

There are not many documents that need to be checked by Liu Qingquan in the end, but they are often very important things. Liu Qingquan will take a little look at these things very seriously, and even call to ask for many details. In the end, he feels that there is no problem. Some people who have different opinions will also give instructions. They have never directly rejected it. This is a kind of respect for Liu Qingquan's employees, and it is also his own consideration. After all, he is not only in scientific research. There is a bit of promise in the top, and other aspects are completely novices. It is definitely not wrong to listen to your subordinates. Even if you make a mistake and then go back and implement it according to your own opinions, you will appear to be more competent.

Soon, after dealing with a few things, Liu Qingquan came to the institute.

The day-to-day affairs of the research institute have been formalized after the reform, and the research work is very boring. Many times, doing repetitive things for many years, it is difficult to produce results, and only those who really like research will fall in love with this kind of work.

Liu Qingquan came to the Institute of Information Science and Technology. He remembered a newcomer who performed very well. In this reform, he was rated as a middle-level 1. He is a graduate of Zhejiang University majoring in communications. His name is Zhou Jingbo. He has considerable experience in communications research. He has a solid foundation, and is very passionate and innovative.

As a researcher in the middle section of 1, Zhou Jingbo has the right to form his own research group. At this time, he is bringing a few people who are also interested in communication technology research and are holding a wire-like thing that is constantly turning, next to a Weird, rudimentary signal-receiving equipment is beeping non-stop.

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

Boss, you are here. We have been studying electromagnetic wave receiving technology recently, and we have already achieved good results. We can report to the research institute soon. Zhou Jingbo saw Liu Qingquan coming over and hurried over to report. The researchers who came later were also slow. Slowly followed and called Liu Qingquan boss.

The electromagnetic wave technology just mentioned by Zhou Jingbo is the main technology of modern communication. Basically, all communication now still relies 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 everyone uses is electromagnetic wave technology. Communication companies receive and transmit electromagnetic wave signals through large-scale building signal base towers on the ground to realize mobile phone communication, not through satellite signals as everyone imagines. .

What is very interesting about the inventors of electromagnetic wave technology is that there is no unified and universally recognized scientist. In the United Kingdom, people regard Maxwell as the founder of radio, and think that he was the first to point out the existence of electromagnetic waves; in the United States, some people think that DeForest is the father of radio, because he invented the triode, which is the source of radio communication equipment. Heart; in Russia, only Popov is recognized as the founder of radio communication; in the eyes of Western scientists, Italian Marconi is the inventor of radio communication, for which he won the Nobel Prize in Physics; in Germany, people think that Hertz is the The pioneer of radio, because he first proved the existence of electromagnetic waves, the unit of vibration frequency of electromagnetic waves is named after his surname; who invented radio communication...

In this scientific achievement, compared with others, there are too many different opinions. …

Electromagnetic wave communication technology also has its own natural advantages, but now more and more scientific research shows that electromagnetic wave technology has a very huge impact on living beings and can cause harm to the human body.

Increasingly dense electromagnetic wave signal transmitting and receiving towers, especially high-power electromagnetic transmitters, broadcast transmitters, ultra-high voltage transmission lines for power transmission, urban transportation systems, as well as home computers, TVs, microwave ovens, electromagnetic cookers, mobile phones, etc. will cause electromagnetic pollution to the environment.

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

Electromagnetic waves are most harmful to the human body in three aspects: thermal effect, non-thermal effect and accumulation effect, causing the body balance disorder, causing headache, dizziness, insomnia, forgetfulness and other neurasthenic symptoms; causing fatigue, loss of appetite, irritability and irritability; The human body's thermal regulation system is out of balance, resulting in increased heart rate, increased or decreased blood pressure, breathing disorders, and leukopenia; it contributes to the occurrence and deterioration of cardiovascular disease.

Women, especially pregnant women, and children are greatly affected by electromagnetic waves, and the damage caused 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 method that uses quantum entanglement effect to transmit information.

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

Compared with the traditional electromagnetic wave communication technology, it is far from being comparable to the traditional technology in terms of efficiency and safety.

Quantum communication will never leak secrets. One of them is that the key of quantum encryption is random. Even if it is intercepted by the thief, the correct key cannot be obtained, so the information cannot be decrypted. Second, there is entanglement in the hands of both parties. If the quantum state of one particle changes, the quantum state of the other will change immediately, and according to quantum theory, any macroscopic observation and interference will immediately change the quantum state, causing it to collapse, so The information obtained by the stealer due to the interference has been destroyed, not the original information.

In terms of efficiency, the unknown quantum state to be transmitted will be in an entangled state before being measured, that is, it represents multiple states at the same time. For example, one quantum state can represent two numbers 0 and 1 at the same time, and 7 such quantum states can be represented simultaneously. 128 states or 128 numbers: 0~127. Such a transmission of optical quantum communication is equivalent to 128 times of classical communication. It is conceivable that if the transmission bandwidth is 64-bit or higher, then the difference in efficiency will be an astonishing 2, and more!
