Universe dominance

In the quantum communication laboratory, Duan Guang and Li Fu carefully discussed some problems encountered in quantum communication technology. Other scientists around them also chimed in from time to time and put forward some of their own opinions. Sometimes it is better to have ideas than not at all. The idea is better, even if this idea seems ridiculous.

"We have done many experiments, but they still have no effect. We have even conducted joint research with other laboratories, but now there is no progress."

Next to Duan Guang, Pan Feng, a top scientist in the field of quantum communication, also seemed very irritable. The days when there was no progress were the most uncomfortable. The key now was that there were no new ideas.

Li Fu frowned and thought rapidly in his mind. After chatting for more than half an hour, Li Fu already roughly understood their current progress, research ideas and methods, and also figured out why they were stuck in a bottleneck period. And there is no progress at all.

"In fact, we might as well put aside all the current research results and ideas, etc., and assume that we start from scratch and study quantum communication technology from scratch. What will we do?"

Li Fu thought for a while and asked. The ideas and methods Li Fu mentioned are often used in scientific research, so everyone is familiar with them. Sometimes when we encounter a difficult problem, we never get the answer. When the problem arises, we will completely abandon the original way of solving the problem and use another way of thinking to solve the problem.

"We have tried many times, but to no avail."

Duan Guang shook his head. It was not that the team he led had not tried to start over, but every time they would end up on the same old path, and their efforts would end up being useless.

"Let's first talk about the principle of quantum communication. Quantum communication is a brand-new technology that implements communication based on quantum entanglement. In other words, the root of this technology is quantum entanglement."

Li Fu smiled and continued to speak. The scientists around him naturally knew what he was talking about. They dealt with quantum communication technology every day, so these most basic things were naturally clear to them.

"Then let's talk about the quantum entangled state. We can very popularly compare the quantum entangled state to a pair of brothers. It's just that these brothers are a bit special. Their every move is exactly the same, no matter what either one does. reaction, the other one will react accordingly. Quantum communication technology is based on this most basic principle. "

Everyone stopped what they were doing, gathered around Li Fu, and listened carefully to what Li Fu said. Everyone knew that Li Fu didn't give many lectures. It was a rare opportunity, and he might be able to gain a lot from it.

"We can now understand quantum communication technology in this way. We separate these two brothers with characteristics, that is, two terminals. Then we control one of the brothers to convey the information, and the other brother will respond accordingly. This way information can be transmitted.”

Li Fu's analogy was very easy to understand. Even people who don't understand quantum communication at all can understand it, not to mention everyone present nodded.

"So we can now divide the problems encountered in the research of quantum communication technology into two parts. One is how to separate the brothers and make them safe even if they are separated by a long distance. The other is how to control them. These two brothers, let them install the way we need to convey the message."

"Now that we have entered a bottleneck period, we should think carefully about the fundamental principles of this technology, and then carefully consider whether the work we are doing now is useful."

"Quantum communication technology is essentially two things. One is to separate the brothers, and the other is to control the brothers to realize the transmission of information."

Li Fu expressed the fundamental principles of quantum communication technology in easy-to-understand language step by step.

"Separate and control!"

Duan Guang thought carefully about what Li Fu said in his mind, and suddenly felt enlightened, and ideas came to him like a spring. Before, he felt that there was no way to start, but now he suddenly felt that there were many ideas to try.

"Yes, we seem to have gone astray now. In fact, in essence, quantum communication does not need to establish any channels at all. We only need to control these strange brothers at both ends. Between the two ends There is no need for any connection in energy, matter, or distance at all.”

"Now we are still thinking about whether this channel is unstable, how to reduce the sensitivity of the channel, etc. In fact, these are completely unnecessary and a waste of time."

Pan Feng also had a sudden realization, a smile appeared on his face, and he seemed to have figured out some problems and key points.

"Yes, in fact, we can understand it very simply. We use two cages to separate the brothers. Because of the specialness of the brothers, even if they are far apart, we can pass through Control the brothers to transmit information in real time, regardless of distance and time."

Duan Guang also smiled at this time, and the sadness on his face suddenly disappeared. He suddenly felt that he had many, many ideas that he wanted to conduct experiments to verify immediately.

Then Duan Guang, Pan Feng and others began to have a heated discussion, one by one, ideas emerged one after another, and they continued to discuss with each other. Li Fu on the side saw this He smiled slightly at the scene. He had seen this scene many times.

Li Fu explains and analyzes a problem in essence, and scientists can benefit a lot from it. Sometimes they are so excited that they will naturally find someone to explain their thoughts and ideas, and it is normal to have heated discussions with each other. things.

"We have always used light quanta (photons) to conduct experiments, because these photons are the easiest basic quanta for us to obtain, but that is why we want to build special channels. In essence, quantum communication is not possible at all. No access is needed, so that’s where we go astray.”

"But if we don't build a channel, how can we achieve quantum communication? Moreover, the characteristics of photons are that they have zero mass when stationary, but they have energy, momentum, and mass when moving at the speed of light. At the same time, they can transmit electromagnetic interactions to each other. , these properties are the most accessible to us now."

"We should think about it this way. We cannot give away the most essential things for quantum communication. This is like drinking poison to quench thirst. Although we have temporarily achieved quantum transmission, this also limits the future development prospects of quantum communication technology. , we should abandon this idea and method from the beginning.”

"Back to the essence, what we should think of is how to separate the two brothers who are entangled with each other, and then think of how to control the two brothers. This is the right way."

"Yes, let's first discuss how to separate the two brothers who are entangled with each other. I think we should first think about what methods and methods can be used to preserve them."

"But how should photons be separated?"

"Why must we choose photons? There are many kinds of basic particles. We can choose from many, and we are not necessarily limited to photons."

"..."

The more everyone discusses, the more ideas there are. Many things actually need someone to give some inspiration. If you give a few clicks on the key points, you will suddenly become enlightened and enlightened, and all the troubling problems will be quickly solved.

The more people discussed, the more excited they became. Soon, Duan Guang, Pan Feng and others hurried to experiment again, leaving Li Fu aside. They were all excited now, and their hearts were boiling. They had countless experiments and ideas. If you want to confirm everything one by one, you don't have time to pay attention to Li Fu.

"Finally, the discussion has reached a key point. It is estimated that it won't be long before they can develop quantum communication technology. By then, they will no longer have to worry about long distances. In the future, they can also communicate with the earth in real time when traveling to alien galaxies. Contact, another weapon will be added to conquer the stars and the sea. "

Li Fu touched his chin and left the quantum research laboratory. There was no point in staying any longer. Duan Guang, Pan Feng and others had no time to pay attention to him. However, this time Li Fu achieved his goal.

Quantum communication technology is very critical, because it is indispensable for interstellar and cosmic navigation. Without powerful communication technology, in a universe where the unit is light years, traditional communication technology cannot keep up with the development needs of the times. .

Just like the Age of Discovery on Earth, before the advent of electromagnetic communication technology, those powerful colonial countries actually had very loose control over colonies around the world, and often uprisings and riots occurred in a colonial area. It usually takes several months for the information to be transmitted back to the homeland, and it takes several more months for a response to be made.

If the European colonists had not relied on the technological superiority of giant ships and cannons, they would not have been able to rule huge colonies. They could rule large colonies with only a small amount of troops and force.

So at that time, European colonists had unprecedented support for science and technology. They were eager to have more advanced giant ships and more powerful cannons. They hoped that their ships could run faster, and of course they hoped that they could control them in real time. The basic situation of various colonies in the world in order to better carry out colonial rule.

Until the birth of electromagnetic communication technology, European colonists were ecstatic. They no longer had to worry about communication problems, and their control over the colonies was naturally much stronger.
