The military's actions are progressing secretly. Another team led by Duke to study quantum entanglement has been constantly producing amazing results. As the most critical theoretical basis in quantum computers, although quantum entanglement research has made some progress in decades, the existing theoretical basis makes the preparation of quantum entangled states very difficult. At present, the most cutting-edge entangled state preparation records have prepared super-entangled photon Schrödinger cat state. The highest number of entangled quantum bits is still 2 digits, which is far from the requirements of quantum computing.

More importantly, it is impossible to break through the current method. Just like cars using internal combustion engine technology, the speed can reach 200 kilometers, and in extremely special circumstances, it may exceed 300 kilometers, but it is impossible to break through the speed of sound. Therefore, humans' hope of breaking through the speed of sound must find something else. On the one hand, they must turn from the ground to the sky, and on the other hand, they must use a brand new power technology.

Based on the existing theory, Duke has proved the limits of existing quantum entanglement research methods through theoretical deduction. Although this theory does not directly help solve the preparation of quantum entanglement, it only proves that the current path cannot be done, Duke applied some new hypothetical theories in the deduction, which immediately attracted the attention of experts in the field of quantum research.

Before everyone could understand Duke's difficult and obscure paper, Duke completed his theoretical preparation and proposed a new quantum entanglement hypothesis in the project team, a new preparation method that was later widely known as "Duke's entanglement", and began to start from Duke's laboratory.

Thanks to the theoretical basis given by Bileme, the new method proposed by Duke quickly achieved initial success, and the first successful preparation was quickly completed in the laboratory, and it also exceptionally easily set a world record for the preparation of entangled states, achieving entangled states of more than 100 ions!

The scientists in the research team got this result for the first time and could hardly believe their eyes. They repeatedly performed the same experiments several times and obtained the same results before they were sure that they had completed a new milestone in the history of quantum research.

However, just as they were preparing to name this new preparation method "Du's Effect" and wrote the paper to publicly publish it, Duke asked everyone to keep it confidential because this method is the only way known to the world to make the practical use of quantum computing and quantum communication. Once the principles are disclosed, it may allow other genius scientists in the world to find specific implementation methods.

Although this is an achievement that is enough to highlight one of the most important discoveries in the history of quantum theory, it is fully qualified to win a new Nobel Prize. However, it is like the principle of nuclear fission. If it is announced, it will greatly shorten the time when the world enters the quantum era.

Duke has not yet had the idea of ​​being a world-wide harmony, so he prevented the research team from exposing this theory.

Duke's theory was originally a mature quantum theory. After opening this layer of window paper, the research team's subsequent research work was unstoppable. In a few months, it broke through from the entangled state of hundreds of ions of research properties to a truly practical large data volume.

At the same time, the team studying quantum communication also realized an ultra-long-range free space quantum channel based on Duke's theory, successfully realizing the world's first long-distance quantum state stealth transmission of thousands of kilometers. Although due to the experimental nature of the equipment, there is not much information transmitted and the transmission speed is not much practical than traditional methods, these experiments have laid a solid foundation for quantum communication.

Now, although Duke's core achievements in quantum research are highly confidential, even some marginal achievements leaked continue to shock the quantum academic community. Duke's Quantum Experimental Research Center has quickly become a forefront that attracts the attention of world experts.

Duke was of course very happy to see the results of his research groups, but Qin Tairan soon arrived. However, this time it was not only him who came to him, but also an uninvited guest was around him.

"Duke, congratulations on your breakthrough in the research field. Come on, let me introduce you to you. This is General Manager Li Keding, the head of the Chinese aerospace family," Qin Tairan introduced with a look of spring after entering Duke's office and the guest-host seat. Although Duke basically supported the quantum research by SAL, it is nominally affiliated with AVIC's Shenlong Project. As a key special research project, domestic research experts have also been allocated by Qin Tairan, so Qin Tairan is naturally honored for Duke's achievements.

"Today we came to the door, mainly to discuss some things with you." Qin Tairan knew that Duke didn't like to beat around the bush, so he started to go straight to the topic after a brief introduction. "Old Li, you should talk about the specific things."

"Director Du, congratulations to you for your historic achievements in quantum research." Although Li Keding is also a senior executive of a central enterprise who enjoys ministerial treatment, his administrative level is even higher than Duke, he obviously understands his position in front of Duke and his tone seems very polite.

"This is the thing. I know from Lao Qin that you have also made breakthroughs in quantum communication and achieved transmission experiments of thousands of kilometers, so I have an idea." Li Keding paused after briefly introducing the causes and consequences. Although the progress of Duke's research results is now highly top secret, Qin Tairan is obviously not among the restrictions. However, Li Keding is not the target of Duke's achievements. I don't know how Qin Tairan passed the message to him.

However, Duke knew that Qin Tairan was from secret information, so he naturally knew the right way, so although it was a little strange, he didn't want to ask the bottom of the problem. "Mr. Li, you said," Duke said with a smile.

"We are wondering, as the best confidential communication technology now, can you please give priority to quantum communication technology to satellite communication," said Li Keding. "Although we have the Beidou communication satellite system now, it is still acceptable for civilian purposes. In military purposes, we are often disturbed by some opponents, and some secrets have also happened." Although Li Keding's words are a bit implicit, Duke, as the top expert in the IT industry, immediately understood it.

Not to mention the Beidou system, even if it is the new wireless communication technology he invented, although he racked his brains in terms of confidentiality, and even used a special language inside the codec engine, no one could understand special language at all. However, since these things need to be transmitted through electromagnetic waves, it is inevitable that information will be intercepted. However, through any method of encryption, it will always be decrypted. In this way, if the opponent deliberately monitors for a long time, there will always be loopholes that will allow them to decipher some things.

However, quantum communication is completely different, because it is completely different from electromagnetic waves in the transmission, and does not require any carrier to carry and transmit information from one place to another in an unfathomable way on one earth, so the possibility of leakage between two transmission devices is completely eliminated.

For satellite communication, it is obviously an extremely valuable feature to achieve near-absolute confidentiality, because in order to achieve the possibility of spreading information in a large range, satellites always transmit information to a large range of space indiscriminately. Using traditional electromagnetic waves to propagate information, it is inevitable to be monitored by people. Compared with the regional wireless broadband propagation technology invented by Duke, since the opponent can continuously monitor and record, there is more data for supercomputers to analyze and operate in deciphering, so the possibility of loss of secrets is relatively greater.

Seeing Duke understand something, Li Keding said with a wry smile, "Frankly, Dean Du, in fact, not long after the Beidou communication system was put into use, the civilian encryption technology we opened was completely deciphered by the CIA experts. Although the military encryption communication part, although the random encryption method of the military is subject to higher intensity, it often takes not long before it will still be deciphered by the CIA.

Our aerospace department is responsible for the PLA's global communications support task, but now the Beidou system cannot ensure the confidentiality of military communication information. The Military Commission is very concerned about our progress in this regard, which puts great pressure on our Chinese aerospace department, but the requirements of the Military Commission are also very realistic. Now everyone knows that the PLA and the US military are in a state of affairs. For the country, there is a ground fiber communication system as the foundation. In addition, the new wireless broadband communication technology invented by President Du is okay, but for the PLA going overseas, the inability to ensure communication security is a very fatal threat."

Li Keding briefly described these causes and effects, and Duke realized that things were much more serious than he thought.

Just imagine if a PLA aircraft carrier fleet was traveling in the Pacific or Indian Ocean, and suddenly the command of the headquarters was completely interfered with and cut off by the US military, the consequences would be unimaginable. It can be said that if the confidentiality and reliability of this long-range satellite communication is not solved for a day, the PLA's large-scale operations overseas would be worried and pose great risks.

"I understand, Mr. Li, but our current research is still in the laboratory stage and there is still a long way to go before truly mature applications." Duke nodded after hearing Li Keding's words, "The environment on the satellite is a bit special than the ground, and it is even more difficult to achieve."

"I know it's very difficult," Li Keding said for a long time. In fact, he didn't want Duke to come up with results now. That's really unrealistic. He has other ideas. "We also know that this is not something that can be achieved overnight, so I discussed with Lao Qin and transferred a research team that we are studying satellite communications and asked Dean Du to take it together to study. In this way, the ground and both sides of the satellite can carry out research and development at the same time, and the quantum communication time of satellites will be shortened a lot in the future."

So that's how it is. Duke turned his head and looked at Qin Tairan. Old Qin nodded very seriously and said that this was indeed what he and Li Keding meant. It's just that Duke was arrested by quantum research. Although Qin Tairan agreed to cooperate with Li Keding's aerospace department, Duke's approval in the end was to be successful. So Qin Tairan joined hands with Li Keding to discuss with Duke.

If two ministerial executives can come to discuss the joining of a project, Duke is probably the world's most likely to have such a face.

Lao Qin gave face so much, so what else can Duke say, so he can only agree. This is probably a new "Du's effect".
