Quantum technology has two very important branches, one is quantum communication and the other is quantum computer. The United States chose quantum computers on the grounds that quantum computers are more important. In fact, both quantum communication and quantum computers are important, and it cannot be said who is important and who is not.

We are now living in the era of information explosion. It goes without saying how important information is to our daily life. We all have a deep understanding.

Therefore, quantum communication is also very important.

The reason why the United States chose quantum computers and gave up quantum communication is not that quantum computers are more important as the United States claims. Anyone with a discerning eye knows that this is because the United States is not strong enough and can only give up one.

Our country has chosen both, and has also launched a quantum satellite into the sky.

When our country put the quantum satellite into the sky, it had a very huge impact on the world. The foreign media almost overwhelmingly supported us, thinking that we are great.

The United States believes that this threatens the United States, and the United States will lose its right to speak, so the United States announced that it has made significant progress in the field of quantum computers, but it is unclear whether it has really made progress, and only the United States knows in its own mind.

Our country counterattacked and announced that our country has made important progress in the components of quantum computers. The next step is to make something like a USB flash drive, which is easy to carry and has a longer lifespan.

Our country is preparing to establish a quantum computer project within the next five years. ,

This news is much better than the empty announcements made by the United States. It is too specific. The United States loses its temper and can only become dumb and lose the right to speak.

Everyone on Earth knows about this, and it can boost our morale.

When Ye Chen mentioned this, everyone stood up and applauded vigorously. Although they did not make the quantum satellite, they are also very proud.

The applause lasted for a long time before it stopped and everyone sat down again.

"Although our country has made encouraging and great achievements in quantum communication, the satellites we launch are still experimental satellites, which are mainly used for experiments and have not yet entered the stage of use. This means that quantum communication has entered our Life still has a long way to go." Ye Chen waited until the applause stopped, and continued: "Besides, when quantum communication is actually used, there is still a lot of work to be done, and we are looking forward to it."

Everyone knows how much work is required to use a new technology.

"Anti-photonic technology,

The maturity of technology is already very good, and photon information technology has entered our life. "Ye Chen said again: "We are installing broadband now, and the starting point is generally 20M. Why is it so big? That is the fiber used. Ten years ago, or even earlier, optical fiber was generally used by Internet cafes. At that time, if Internet cafes did not use optical fiber, then congratulations, congratulations, your business must be very bad. "

Anyone who likes to go to Internet cafes knows that ten years ago, or even earlier, the business of Internet cafes using optical fiber was very hot, because this was their main signature.

"And now, optical fiber has entered our lives, and now almost all network installations use optical fiber. This is one of the great contributions made by Mr. Gao and the others." Ye Chen smiled and took the lead in applauding.

There was another burst of warm applause, which was given to Mr. Gao and the others who have made great contributions to our country's information technology.

"Fiber optics use the total reflection of light." Ye Chen talked about the history of fiber optics, saying: "The total reflection of light was first discovered in 1870 by the British scientist Tyndall. He made a very impressive Shocking experiment: Drill a hole in a wooden barrel filled with water, and use a lamp to illuminate the water from the top of the barrel. People can see that the luminous water flows out of the small hole in the barrel, the water bends, and the light bends accordingly , the light is actually captured by the curved water."

We all know that light travels in a straight line, but in Tyndall's experiment, this theory was subverted, and light can also be distorted. After Tyndall's research, it was found that: light shoots from water to air, when the incident angle is greater than a certain angle, the refracted light disappears, and all the light is reflected back into the water. On the surface, it appears that light is bending forward in a stream of water.

Later, people created fibers, and when light hits the glass fiber at the right angle, the light travels along the curved fiber.

However, it is not an easy task to really apply this principle of light to our life, which requires a reliable light source. It wasn't until the advent of the laser that the light source problem was solved.

Another problem is the production of optical fibers. This was proposed by Gao Kun, the president of the Oriental Pearl University, who created an optical fiber capable of such transmission and won the Nobel Prize for it.

"The large-scale use of optical fibers has brought about tremendous changes in our lives, which has provided a good accumulation of photon information technology. However, what we are going to talk about today is not this technology, but how photons are like electrons. Spread the word." Ye Chen changed the topic and officially entered the topic.

Everyone cheered up. What Ye Chen said earlier was just a transition, and now he is getting to the point. The most core photon information technology is about to come out of Ye Chen's mouth.

They will be the first to hear about this advanced technology, and they are looking forward to it.

"The advantages of photon communication are large communication capacity and good confidentiality." Ye Chen began to explain formally, saying: "We all know that laser has very superior performance, but there are also many disadvantages, that is, laser is greatly affected by the weather, complicated The weather will weaken the laser, or even disappear, how to solve this?"

Complicated weather has a great impact on the laser, which can weaken the laser or even make the laser disappear, which brings great difficulties to communication.

"Xiaoye is right. It is precisely because of the limitation of lasers that current photon communication can only be carried out between the sky and the earth or between the sky and the sea. What we need to overcome now is how to make photon communication as convenient as electronic communication. This technical threshold is too high Already." Elder Gao was very emotional.

It is not difficult to use satellites to communicate between the sky and the earth or the sky and the sea, and this technology has been overcome.

However, this communication method has great limitations, it cannot be as convenient as electronic communication, and the cost is very high.

The cost of using satellites is not low. The cost of making overseas calls is always much higher than the cost of making domestic calls. Correspondingly, the cost of calling is also much higher.

"If the distance exceeds 10 kilometers, the laser is easily affected by the weather, and the positions of the two sides are uncertain, which makes communication more difficult." Gao Lao continued: "Especially on the battlefield, the enemy's situation The constant change, the changing positions of friend and foe, makes photonic communication impossible."

The situation on the battlefield is the most complicated. The enemy's situation is changing all the time, which leads to the changing position of the army all the time. It is impossible to use photon communication with such huge defects.

"Even so, our country has made great progress." Elder Gao was very proud, and said: "Our country has just conducted a test. The distance between the two planes is 144 kilometers, and 2.5G airborne laser communication has been carried out. The experiment was a success."

Clap clap!

There was warm applause, and everyone was very excited.

Others may not know what this means, but all the technical elites here know what it means.

This means that it only takes 1 minute to transmit a 1080P high-definition movie between two aircrafts. This transmission speed is very fast, it is amazing.

Imagine that if our black ribbon applied this technology, it would not be able to turn on the radar and receive any electromagnetic signals, maintain electromagnetic silence, realize real-time update and track targets, and launch bombs outside the defense zone before the enemy notices anything. Precisely guided weapons or long-range air-to-air missiles to destroy the enemy's key nodes.

In other words, if our black ribbons were equipped with such a device, they could strike wherever they wanted without the enemy even being able to detect them.

That is to say, I'm the only one who beats you, and you can't even see me, so how can you beat me?

In modern warfare, there are a large number of electronic devices that can perform electromagnetic suppression and interfere with the enemy. However, I don't use electronic equipment, but use photonic equipment, so what's the use of your electronic equipment?

If this technology is successful, the United States will have to weigh it carefully. How useful are those advanced electronic equipment in the United States?

Does the big-mouthed president of the United States still dare to provoke us with the "one celestial dynasty" policy?

"Amazing achievement!" Ye Chen exclaimed.

"Xiaoye, what can you do to solve these defects?" Elder Gao asked expectantly.

"This is how I solved it, you see..." Ye Chen turned on the super optical brain, and used projection technology to project his solution.

"This is..." Elder Gao's eyes widened suddenly, with a look of shock on his face.

"This..." Mr. Zheng and the others stared at him with rounded eyes, with shock on their faces.

They are all old experts with in-depth research in this area. The answer Ye Chen gave surprised and shocked them, and made them feel like seeing the blue sky through the clouds and mists.

Others didn't have their attainments, frowning and thinking hard.

Clap clap!

Elder Gao stood up and took the lead in applauding.

Mr. Zheng and the others stood up and applauded vigorously.

The information research and development team who came with Mr. Gao and the others were all very excited. They all stood up and clapped their hands hard.

This solution is something they are looking for but cannot get. Although what Ye Chen gave has not been verified, they will not fail to know that it is very valuable from their perspective.

Saying that it was successfully resolved, they dare not draw this conclusion without verification. However, they can be sure that Ye Chen's method can take a big step forward in photon information technology.

Xiao Lingyue and the others believed in Gao Lao's vision, stood up and applauded.

The applause lasted for a long time before it stopped.

Next, Mr. Gao and the others asked questions.

They are indeed outstanding scientists who have made great contributions to the progress of our country's information technology. The questions they ask are very professional and cutting-edge.

If another person would definitely not be able to answer, Ye Chen responded fluently, which surprised Mr. Gao and the others, but also filled them with joy.

Elder Gao and the others asked too many questions, and Ye Chen spent several days answering them.

When Ye Chen finished answering, Elder Gao was satisfied, and said: "The next thing is to report to the higher authorities, build corresponding experimental equipment, and conduct verification."

No matter how good the theory is, it needs to be verified.

Ye Chen didn't have anything to do later, he returned to the laboratory and began to verify composite materials.

After his efforts, the composite materials were finally verified.
