On May 10, 13 years ago, that is, about nine and a half years ago, the strategic vision of the United States really did not need to be said, and the scientists of one of their national laboratories revealed to the public that they had quietly operated a quantum Internet system in the past period of time.

Regardless of whether a complete quantum Internet can be built at that time, this keen insight alone is worthy of admiration.

Two years ago, the White Palace of the United States released a vision of the quantum network, in which it was proposed that in the five years from 20 to 25, the technology companies and related laboratories of the United States will cooperate to demonstrate the scientific basis and key technologies of the quantum Internet, from quantum storage, quantum interconnection, quantum repeaters to high-throughput quantum communication pathways and transcontinental space-based entanglement distribution technology.

"You heard it right." Academician Hu motioned to Lin Yu to be calm, "In fact, we have always suspected that the United States has achieved quantum communication technology one step ahead of us, but they have been hiding it, so we can get the title of the world's first." ”

Lin Yu sat back, constantly thinking about this possibility.

"From dealing with Lao Mi's family, we know that everything they have announced has either been realized for a period of time, or bragged that it has not been realized, in short, it is very ......" Academician Hu Yuan is still thinking about how to describe it.

Lin Yu took it directly, "Old coin!" ”

Academician Hu was stunned for a moment, then nodded, "That's right." ”

"Based on this idea, we further suspect that the Starlink project proposed by Muskar is actually serving the construction of a quantum Internet in the United States."

"We suspect that behind Muska is the military of the United States and the National Aeronautics and Space Administration of the United States is instructing, borrowing the name of Starlink Internet, to deploy quantum network satellites in advance in subsequent launches."

"Therefore, we have also put forward the Yangtze River Delta plan accordingly, hoping to take the lead in building a quantum secure communication backbone network on the mainland."

Lin Yu was very panicked when he heard this kind of secret, is this kind of thing that I can access now?

"Of course, that is only part of the Yangtze River Delta plan, and another part is to build a space quantum Internet plan to take the lead in the future space struggle."

"And my Huaxia star group plan is part of the Yangtze River Delta plan. The Star Constellation Project is led by the national enterprise Huaxia Quantum Network, and is implemented by state-owned enterprises and state-owned technology companies such as Kyushu Star, Shenzhou Aerospace, Huaxia Electronic Technology, Tiantian Shuimu, and Xinghua Space. ”

"For example, the Kyushu Starry Sky-Nebula Project, Shenzhou Aerospace-Zixia Constellation, Huadian Branch-Tianyu Constellation, and the Talent Mizuki-Skywalker Constellation, etc."

"In the name of commercial aerospace starlink, it is used to realize the construction of space quantum Internet."

Lin Yu looked shocked, is this the real purpose of Huaxia?

Awesome wow, my Huaxia!

"So have the relevant technical difficulties been solved?" Now that you know so much, it doesn't hurt to know a little more, right? Lin Yu asked directly.

Academician Hu nodded, "Since you are already planning to go toe-to-toe with the United States and the Western European Union, then go all out." ”

"The relevant technical problems have actually been solved, and it's up to you to be a quantum computer."

Quantum computer, Lin Yu suddenly thought of the task issued by the system.

"So, Academician Hu, you came to me just to let me make a quantum computer?"

Academician Hu nodded.

"But hasn't a quantum computer already been built?"

The quantum integrated circuit designed by Lin Yu is related to the quantum computer, but the quantum integrated circuit is far from the quantum computer.

At present, the quantum computer in the world can not be regarded as a real quantum computer, but can only be regarded as a prototype of a quantum computer, and this kind of quantum computer cannot operate stably at room temperature, and can only operate stably after achieving circuit superconductivity in ultra-low temperature or ultra-high temperature.

To put it bluntly, it is a material problem, and the inability to miniaturize the packaging of quantum integrated circuits is still related to the material problem.

"But the current quantum computer has a system of only 60 qubits, and after many verifications of your design, we found that using the quantum integrated circuit you designed, the qubit capacity of the system has increased to 128 qubits, which is simply a decade of technology."

"Even more efficient than the superconducting circuits of the Josephson junction."

"We have built eight quantum matrix arrays of quantum dots in a 4×4 way, and then carried out low-temperature superconductivity of the constructed quantum integrated circuit, which is now running 25 times faster than the quantum computers that have been published so far."

"Compared to the material, we don't need to worry, because if we are not directly irradiated by the star, the normal temperature in space is about minus 270 degrees, which fully meets the requirements of superconductivity."

"As for quantum computers, we still hope you can join our team, two years ago I led the team to make a quantum computer simulator, although it is claimed to be a prototype, but we all know that it is just a compromise made in response to the quantum hegemony of the United States."

"I guess you know the problem of our simulator 'Chapter 9', right?"

Academician Hu looked at Lin Yu and said.

Lin Yu really wants to say that you, the client, are all here, how can I be embarrassed to say it?

But he nodded anyway, "Yes." ”

"The problem with Chapter 9 is that although it uses 76 optical qubits, it is still only a specific treatment of [Gaussian boson sampling], and it is not even a quantum special digital processing device, but more of an analog computing device." Academician Hu sighed.

"This is also something that can't be helped, on the one hand, we haven't broken through the relevant technical barriers, on the other hand, the United States is menacing, if we don't fight back, we will be ridiculed."

"But the good news is that in the past two years, we have overcome difficulties and successfully built a real prototype of a quantum computer, but it is not enough for a real quantum computer."

"And for the attempt of logical bits, we have basically mastered the relevant applications, and Academician Zhao and I both think that you can help us make a real quantum computer."

Academician Hu's eyes suddenly flashed with trust.

Feeling this gaze, Lin Yu suddenly felt that his responsibility seemed to be infinitely magnified.

"What's the matter, I'm here specifically to pick you up, I've asked the No. 2 leader for this matter, and the No. 1 leader has already acquiesced."

"What do you think?"

Lin Yu thought about it and agreed, "Thank you very much for the trust of the leader and Academician Hu and Academician Zhao, since this is the case, then I will agree." ”

Academician Hu nodded.

"But", Lin Yu gasped for breath and took a turn, "I still have a little project to do now, Academician Hu, can you give me a few days?" ”

Just now Lin Yu made a turn, and Academician Hu's body that had just sat down almost stood up again.
