There are two very important branches of quantum technology, 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, quantum communication and quantum computers are important, and it cannot be said that who is important is not important.
We are now living in an era of information explosion. It is needless to say how important information is to our daily lives. We all have profound experience.
So, quantum communication is equally important.
The reason why the United States chose quantum computers and abandoned quantum communication is not that quantum computers are more important than the United States said. Everyone knows that this is because the United States is not strong enough and can only give up one.
Our country chose both, and it also put quantum satellites into the sky.
After our country put quantum satellites into the sky, it had a very huge impact in the world. The foreign media supported us almost side by side, thinking that we were amazing.
The United States believes that this threatens the United States, and the United States will lose its right to speak. Therefore, the United States announced that significant progress has been made in the field of quantum computers.
Our country counterattacked and announced that our country has made important progress in the components of quantum computers. In the next step, it will be made into a U disk, which is easy to carry and will also extend its life.
Our country is planning to initiate a quantum computer project in the next five years. ,
This news is much better than the empty announcement of the United States. It is too specific. The United States has no temper and can only become dumb and lose its right to speak.
Everyone on the planet knows this, and it can boost our morale.
When Ye Chen mentioned this, everyone stood up and applauded vigorously. Although quantum satellites are not made by them, they are also proud.
The applause lasted a long time, and then it stopped and everyone sat down again.
"Although our country has achieved encouraging great achievements in the field of quantum communication, the satellites we launch are still experimental satellites, 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 for applause to stop, and then continued:" And when quantum communication is really used, there is still a lot of work to do, and we are looking forward to it. "
The use of a new technology, how much work to do, everyone will not know.
"Anti-tourist technology, the maturity of the technology is already very good, and photonic information technology has entered our lives." Ye Chen added: "We now install broadband, and the bottom is generally 20M. Why is there such a big one? That is the optical fiber used. Ten years ago, or even earlier, the optical fiber was generally used in Internet cafes. At that time, if the Internet cafes did not use optical fibers, then congratulations, your business must be bad . "
Anyone who loves to go in and out of Internet cafes knows that ten years ago, or even earlier, the business of Internet cafes using fiber optics was very hot, because this is their main signature.
"Now, optical fiber has come into our lives, and now the network is installed, almost all of which are used optical fiber, which is one of the great contributions they made." Chen Chen smiled and took the lead to applaud.
There was another round of warm applause. This is for the elders who have made great contributions to our country's information technology.
"Optical fiber uses the total reflection of light." Ye Chen talked about the history of optical fiber, saying: "The total reflection of light was first discovered in 1870 and was first discovered by British scientist Ding Daer. ​​He made a very Shocking experiment: drill a hole in a wooden bucket filled with water, and illuminate the water from the bucket with a lamp. People see that the glowing water flows out of the small hole in the bucket, the water stream bends, and the light also follows. , Light was actually captured by the tortuous water. "
We all know that light travels in a straight line, but in Tyndall's experiments, this theory is subverted and light can be distorted. According to Tyndall's research, light is emitted 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, light seems to bend in the current.
Later, people created fibers, and when the light entered the glass fiber at an appropriate angle, the light went along the curved fiber.
However, it is not easy to truly apply this principle of light to our lives, which requires a reliable light source. It was not until the advent of the laser that the light source problem was resolved.
Another issue is the production of optical fibers. This was proposed by Gao Kun, president of the Oriental Pearl University, who made the optical fiber capable of this transmission, and won the Nobel Prize.
"The large-scale use of optical fiber has made a huge change in our lives, which has accumulated a good accumulation of photon information technology. However, what we are talking about today is not this technology, but how photons are like electrons. Spread. "Ye Chen turned a word and officially entered the topic.
Everyone looked up, Ye Chen was just talking about the transition, and now I have entered the topic. The core photonic information technology will be said from Ye Chen's mouth.
They will be the first to hear about this advanced technology, and they look forward to it.
"The advantage of photonic communication is that the communication capacity is large and the security is good." Ye Chen began to explain formally, saying: "We all know that lasers have excellent performance, but also have many disadvantages, that is, lasers are greatly affected by weather and complicated. The weather will weaken the laser and even disappear. How can this be solved? "
The complicated weather has a great impact on the laser, which can weaken the laser and even make it disappear, which brings great difficulties to communication.
"Xiaoye is right. It is precisely because of this limitation of lasers that photon communication can only be performed between heaven and earth or sky and sea. What we are trying to overcome now is how to make photon communication as convenient as electronic communication. The technical threshold is too high. Now. "Gao Lao was very moved.
It is not difficult to use satellites to communicate between heaven and earth or the sea. This technology has been overcome.
However, this communication method has great limitations, cannot be as convenient as electronic communication, and is costly.
The cost of using satellites is not low. The cost of making overseas calls is much higher than the cost of making calls in China. Correspondingly, the cost of telephone calls is much higher.
"If the distance exceeds 10 kilometers, the laser will be easily affected by the weather, and the positions of the two sides are uncertain, which will cause greater difficulties for communication." Gao Lao continued: "Especially on the battlefield, the enemy's situation It ’s always changing, the position of the enemy and ourselves is always changing, and this difficulty makes photonic communication unusable. "
The situation on the battlefield is the most complicated. The situation of the enemy is changing at all times, which causes the position of the army to change at all times. Photonic communication with such a huge defect cannot be used.
"Even so, our country has made great progress." Gao Lao was very proud, saying: "Our country has just conducted a test. The two machines are 144 kilometers apart and 2.5G airborne laser communication has been carried out. The experiment was a success. "
Poppy!
The warm applause sounded, and the crowd was particularly excited.
Others may not know what this means, but all of you present here are technical elites who know exactly what it means.
This means that if you want to transmit a 1080P HD movie between the two planes, it only takes 1 minute. This transmission speed is very fast and amazing.
Imagine that if our black ribbon applied this technology, we could not turn on the radar and receive any electromagnetic signals, keep electromagnetic silence, achieve real-time updates and track targets, and send out of the defense zone before the enemy notices anything Identify guided weapons or long-range air-to-air missiles to destroy critical nodes of the enemy.
In other words, if our black ribbon is equipped with such equipment, we can hit wherever we want, and the enemy will never find out.
In other words, I can only hit you. You can't see me even if you watch it. How can you hit me?
In modern warfare, there are a large number of electronic devices that can suppress electromagnetic waves and interfere with the enemy. However, I do n’t use electronic devices. I use photonic devices. What electronic devices do you use?
If this technology is successful, the United States will have to weigh it, how much use can be made of those advanced electronic equipment in the United States?
Does the big-mouthed president of the United States dare to use the "one heaven" policy to challenge us?
"Amazing achievement!" Ye Chen admired.
"Xiaoye, what is your solution to these defects?" Gao Lao asked expectantly.
"I solved it this way, you see ..." Ye Chen turned on Super Light Brain and used projection technology to project his solution.
"This is ..." Gao Lao's eyes widened sharply, his face shocked.
"This ..." Zheng Older narrowed his eyes and stared at him with regret.
They are all old experts, and they have studied in this area very deeply. The answer Ye Chen gave them is very surprising and regrettable.
Others did not have their accomplishments, frowning and thinking hard.
Poppy!
Gao Lao stood up and applauded.
Zheng Lao, they immediately stood up and applauded vigorously.
The information R & D team that came with Gao Lao was very excited. They stood up and clapped their hands.
The solution was that they were looking for something unavailable. Although the things Ye Chen had given had not yet been verified, they would not know that it was very valuable in their eyes.
They said they resolved it successfully, and they did not dare to reach this conclusion without verification. However, they can be sure that Ye Chen's approach can take photonic information technology a big step forward.
Xiao Lingyue they believed in Gao Lao's vision and stood up and applauded.
The applause lasted a long time before it stopped.
Next, Gao Lao asked questions.
They are indeed outstanding scientists who have made great contributions to the advancement of information technology in our country. The questions they ask are very professional and cutting-edge.
If you can't answer for another person, Ye Chen's response is like a stream, which makes Gao Lao both surprised and full of joy.
Gao Lao asked too many questions, and Ye Chen was answering questions for a few days.
Until Ye Chen finished answering, Gao Lao was satisfied and said, "The next thing is to report to the above, build the corresponding experimental equipment, and verify it."
No matter how good the theory is, it needs to be verified.
Nothing happened to Ye Chen later, he returned to the laboratory and began to verify the composite.
After his efforts, the composite material was finally verified.
