Great Power Heavy Industry: Rise

Chapter 389 Long Distance Communication
Now that the space agency has no objections, and the personnel of the Red Star Company have no objections, Zhong Cheng announced that he will start implementing the Mars impact project from January next year.

For the sake of convenience, he named this project "Recovery Project", which means to revive the world of Mars and become the home of mankind.

The main implementation of the recovery plan is to rely on four Luanniao Kongtianfei 305s, which will transport equipment and supplies between the Earth and Mars in the next eight months.

The 360 ​​large-scale Zhurong electric pushers and ore refining equipment used to capture the Icarus asteroid are definitely not enough. In the past few months, more equipment needs to be produced and shipped to Mars.

Of course, a large number of people will be needed to carry out the task of breaking up Phobos and adjusting the orbit of the asteroid.

This plan is also a huge project, and the participants discussed the candidate for the project commander.

Everyone objected with one voice that Zhong Cheng would go to Mars to direct himself. All the senior personnel of the company hoped to complete this glorious and arduous task.

Zhong Cheng has nothing to do about it, there are indeed a lot of things on the earth recently, it is impossible for him to leave for half a year.

Mars is far away from the earth, and the communication delay of several minutes or ten minutes makes people crazy. Even if he wants to deal with the company's affairs remotely, he must first solve this communication problem.

In the end, after some controversy among the crowd, Zhong Cheng decided to lead the team to Mars with Zheng Yilun and Liu Yuzhu to implement the recovery plan.

The reconstruction project of Red Star Land Reclamation Company in the great desert of Australia is nearing completion, and Zheng Yilun can already get out.

As for Liu Yuzhu, Fan Chengjun, Huang Xueshen, Zhang Liang, and Luo Na are now in the Kunlun Research Institute to shoulder the burden, and the "old people" of Zhong Cheng's generation have much less work pressure.

……

Zhong Cheng still handed over the heavy responsibility of the second phase of the Nantianmen project to Zhou Hu, and let him sit in Kunlun City, while he himself returned to Beishan to handle the affairs of the entire company.

The aggressiveness of the Mutual Aid Association has aroused his fighting spirit, and he should make a good plan.

Zhong Cheng felt the current slow speed of interstellar communication. After returning to Beishan headquarters, he called Li Mei and Gui Bin to discuss the issue of long-distance communication.

Li Mei was in charge of radar and communication technology at the Kunlun Research Institute. Zhong Cheng arranged for the subject of long-distance communication very early on, and asked Gui Bin to provide support in computer hardware.

When the two came to Zhong Cheng's office, Zhong Xin was there. He was called by Zhong Cheng to inquire about the development progress of the curvature engine technology.

Zhong Xin greeted Li Mei and Gui Bin and wanted to leave, but was stopped by Zhong Cheng and asked him to listen.

After the four of them sat down in the reception area of ​​the office, Li Mei first reported the progress of her team's research.

Under the current basic theoretical conditions, the realization of long-distance communication must be inseparable from quantum entanglement.

Li Mei's team has made many achievements in the field of quantum entanglement in recent years.

The preparation and manipulation of multiphoton entangled states has always been a research focus in the field of quantum information.

The nonlinear process in crystals is commonly used in the world to generate multi-photon entangled states, and the difficulty will increase exponentially with the increase of the number of photons.

They successfully prepared a 32-photon entangled state, and further used the generated entangled state to complete a 32-port quantum communication complexity experiment.

The experimental results have surpassed the previous boundaries, demonstrating the superiority of quantum communication with strong anti-interference ability and fast transmission speed.

Li Mei then talked about a large number of achievements in quantum communication.

But Zhong Cheng asked, can real-time communication between the earth and Mars be realized?

Li Mei said embarrassingly that it is not possible for the time being, but it should be possible in a few years.

After hearing Li Mei's words, Zhong Cheng didn't express anything, but Gui Bin raised doubts.

This year, Li Mei's team used the optical fiber channel of the space elevator to successfully increase the distance of quantum "hyperspace traversal" to 300 kilometers.

However, due to the loss in the optical fiber channel and the interference of the environment, it is difficult to greatly increase the distance of quantum state teleportation.

In this regard, Gui Bin believes that the research and development direction of Li Mei's team is wrong, and it does not mean that their research is useless, but that it is impossible to solve the communication problem between planets.

Li Mei asked angrily, "Our direction is wrong, then Gui Bin, you can talk about a good direction. You have been researching quantum computers for so many years, and you still haven't made any progress!"

Gui Bin was questioned. Quantum computers have always been his heart disease. After nearly 20 years of work, there is still no progress.

His research is also stuck on quantum entanglement.

Quantum entanglement is a physical resource, such as time, energy, momentum, etc., that can be extracted and transformed.

Entangled states play an important role in various aspects of quantum information, such as quantum teleportation, quantum key distribution, and quantum computing.

However, due to the limitation of experimental conditions and the influence of unavoidable environmental noise, not all entangled states prepared are maximally entangled.

On the other hand, the pure entangled state will degenerate into a mixed state due to the decoherence of the environment.

Using such hybrid entangled states for quantum communication and quantum computing would lead to information distortion.

In order to achieve better quantum communication or quantum computing effects, it is necessary to purify the mixed entangled state into pure entangled state or close to pure entangled state through entanglement purification technology.

Therefore, how to purify high-quality quantum entangled states has become the biggest problem for Guibin's team in developing quantum computer technology.

Seeing that the two experts fell silent, Zhong Cheng had a headache.

He didn't feel the urgency of long-distance communication before, and he didn't care much about their research progress.

But after these two deep space voyages, he suffered a lot.

You send a message, and it takes half an hour for the other party to receive it, and then it takes half an hour for the other party to reply to the message.

A call that can be completed in a few minutes on the earth takes hours between the stars.

Let people who are accustomed to modern communication methods return to the communication method of writing letters five or sixty years ago.

More importantly, the ultra-long distance in the starry sky makes intelligent robots useless, and everything returns to manual operation.

Moreover, in Zhong Cheng's plan, if Red Star Company can take the lead in developing long-distance communication technology, it will play a vital role in possible interstellar wars in the future.

Just when Zhong Cheng wanted to end the conversation, Zhong Xin, who had been listening for a long time, suddenly said: "Brother, I have an idea, I wonder if it will work?"

The three of them looked at Zhong Xin, and Li Mei said first: "Xin Xin, just say what you think, and no one will laugh at you if you say something wrong!"

Zhong Cheng nodded, and Zhong Xin said slowly: "I think you think the application of quantum entanglement in long-distance communication is complicated, but it is actually a very simple thing!"

"Hahaha!"

Li Mei laughed out loud when she heard the words, "Xinxin, do you really dare to say that our research for so many years has been in vain?"

Gui Bin said depressedly: "Li Mei, but you agreed not to make jokes, look how you smile!"

"you!"

Li Mei glared at Gui Bin, then turned to Zhong Xin and said, "Xin Xin, I'm sorry, you continue talking!"

Zhong Xin chuckled, he was actually used to Li Mei's character, and he didn't care.

"For long-distance communication, we don't need a complex quantum entanglement state, such as eight-photon or sixteen-photon entanglement, we only need two electrons for entanglement!"

"what?"

Li Mei exclaimed!
