cosmic hegemony

Chapter 258, Mao Sai suddenly opened
In the quantum communication laboratory, Duan Guang and Li Fu carefully discussed some problems encountered in quantum communication technology, and other scientists around them also interjected a few words from time to time and put forward some opinions of their own. Sometimes it is better to have ideas than not to have any. The idea is better, even if the idea seems absurd.

"We have done many experiments, but it still doesn't work. We even conducted joint research with other laboratories, but there is no progress."

Next to Duan Guang, a top scientist in the field of quantum communication, Pan Feng, also seemed very irritable. The days without progress are the most uncomfortable. The key now is that there are no new ideas.

Li Fu frowned, thinking rapidly in his mind. After chatting for more than half an hour, Li Fu already roughly knew their current progress, research ideas and methods, and also figured out why they fell into a bottleneck period. And no progress at all.

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

Li Fu thought for a while and asked. The ideas and methods Li Fu said are often used in scientific research, so everyone is familiar with them. Sometimes when we encounter a problem, we still can’t get the answer. When the time comes, we will tend to completely abandon the original solution ideas and try to answer them in another way.

"We have tried many times, but it didn't work."

Duan Guang shook his head. It's not that the team he led didn't try to start over again, but every time they would end up on the old path before, and they still did nothing in the end.

"Let's first talk about the principle of quantum communication. Quantum communication is a brand-new technology based on quantum entanglement to realize communication. That is to say, the foundation of this technology is quantum entanglement."

Li Fu smiled and continued to speak. The scientists around him are naturally clear about these things he said. They deal with quantum communication technology every day, and these most basic things are naturally clear.

"Then let's talk about the quantum entanglement state. We can compare the quantum entanglement state to a pair of brothers in a very popular way, but this pair of brothers is a bit special. Their every move is exactly the same, no matter what one does. response, the other one will respond accordingly, and quantum communication technology is based on this most basic principle."

Everyone stopped their work one after another, gathered around Li Fu, and listened carefully to Li Fu's lectures. Everyone knew that Li Fu's lectures were not many, and the opportunities were rare, and they might be able to gain a lot from them.

"Quantum communication technology can now be understood in this way. We separate the brothers of this characteristic, that is, two terminals, and then we transmit information by manipulating one of the brothers, and the other brother will respond accordingly. This is how information can be transmitted.”

Li Fu's analogy is very easy to understand, even people who don't understand quantum communication at all can understand it, let alone everyone present, they all nodded one by one.

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

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

"Quantum communication technology is essentially two, one is to separate the pair of brothers, and the other is to manipulate the pair of brothers to realize the transmission of information."

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

"Separate, control!"

Duan Guang thought carefully about what Li Fu said in his mind, and suddenly felt that he was suddenly enlightened, and his ideas emerged 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 this pair of strange brothers at both ends. Between the two ends There is no need for any energy, material, or distance connection at all.”

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

Pan Feng also suddenly realized, with a smile on his face, as if he had figured out some problems and key points.

"That's right, in fact, we can understand it in a very simple way. We use two cages to separate this pair of brothers. Manipulate the pair of brothers to transmit information in real time, regardless of distance and time."

Duan Guang also showed a smile at this time, and the sadness on his face suddenly disappeared, and he suddenly felt that there were many, many ideas that he wanted to carry out experiments to confirm.

Then Duan Guang, Pan Feng and the others began to have a heated discussion with each other. Ideas emerged one after another, and ideas were brought up one after another. They kept discussing with each other. Li Fu on the side saw this The scene, with a slight smile, he has seen such a scene many times.

Scientists can benefit a lot from Li Fu's explanation and analysis of a problem in essence. Sometimes they are excited, and they will naturally find someone to explain their ideas 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 this photon is the basic quantum that we can most easily obtain, but it is also because of this that we think about building special channels. In essence, quantum communication does not exist at all. Any kind of access is needed, so we're going astray at this point."

"However, if we don't build channels, how can we realize quantum communication, and the characteristics of photons are that they have zero mass when they are at rest, and they have energy, momentum, and mass when they move at the speed of light, and at the same time, they can transmit electromagnetic interactions to each other." , these characteristics are the most accessible fundamental quantum for us now."

"We should think about it this way. We can't give away the most essential things for the sake of 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 very beginning.”

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

"Yes, let's first discuss how to separate the pair of brothers who are entangled with each other. I think we should first think about the method and method to save it."

"But what should the photons do to separate?"

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

"..."

The more everyone discusses, the more ideas there are. Many things actually need someone to give an inspiration. If someone clicks on a key point, it will suddenly become clear and clear, and all the troubled problems will be solved quickly.

The more people discussed, the more excited they became. Soon, Duan Guang, Pan Feng and others rushed to experiment again, leaving Li Fu aside. They are all passionate now, their hearts are already boiling with enthusiasm, and countless experiments and ideas are on the way. To confirm one by one, there is no time to pay attention to Li Fu.

"Finally, the discussion has reached the key point. It is estimated that they will be able to figure out the quantum communication technology in a short time. At that time, they will no longer have to worry about the long distance. In the future, they can also communicate with the earth in real time when they go to other galaxies. Contact, this Conquer the Stars and Seas will add another sharp weapon."

Li Fu rubbed his chin out of the Quantum Research Laboratory, and there was no point in staying any longer. Duan Guang, Pan Feng and the others had no time to pay attention to themselves, but this time Li Fu's goal was also achieved.

Quantum communication technology is very critical, because it is an indispensable thing for interstellar and cosmic voyages. Without powerful communication technology, in the universe with units of light years, traditional communication technology cannot keep up with the development needs of the times. .

It’s like the Age of Discovery on Earth. Before the emergence of electromagnetic communication technology, those powerful colonial countries actually had very loose control over the colonies around the world, and often there were uprisings and riots in a colonial area, etc., It usually takes a few months before it can be sent back to the mainland, and it will take several months to respond.

If the European colonists hadn't relied on the technology of giant ships and cannons to overwhelm their advantages, they would not be able to rule huge colonies at all, and they could rule a large colony with a small force and force.

So at that time, European colonists had unprecedented support for technology. They were eager to have more advanced giant ships and more powerful cannons, and hoped that their ships could run faster. The basic situation of each colony in the world for better colonial rule.

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