It was only then that Xu You realized the matter of the quantum error-correcting code.

"Academician Han, I thought this was the measured data after using my set of quantum error-correcting codes."

"We are still using the previous set of quantum error-correcting codes, so the fidelity is still a bit low. However, when the number of qubits has increased by nearly twenty times, such a high fidelity can still be achieved. It is said that the new control line circuit you designed has a very good effect."

This is also the reason why Han Shubin did not want to make too many qubits before.

Each additional qubit doubles the potential capacity of a quantum processor.

But at the same time, there are many problems that need to be solved.

If we simply increase the number of qubits without considering other issues.

The overall performance of quantum chips is likely to decline instead.

"Xu You, since you edited the set of quantum error-correcting codes, please help with this part of the work."

"Okay, Academician Han."

Xu You also had this intention, and together with Han Shubin, Chang Xiaoping and others, started the processing of quantum error-correcting codes.

For this new quantum chip, Xu You's set of quantum error correction codes also needs to be improved accordingly.

Of course, such work is not complicated.

In a few days, the quantum error-correcting code has been improved, and it is well adapted to the new generation of quantum chips.

After the work on the quantum error-correcting code was finished, Han Shubin organized the second measurement experiment.

In the calculation speed measurement of the quantum chip, the task of quantum random line sampling is also performed again.

This time was no different from the last time, and it still took only about 3 seconds.

The quantum error-correcting code does not affect the computing speed of the quantum chip, but plays a role in reducing the transmission error rate.

The next fidelity measurement experiment is crucial.

Han Shubin, Xu You, Chang Xiaoping and the others all felt a little nervous about this.

If this time, the fidelity of the double-bit gate can reach more than 99%, then the new generation of superconducting quantum computers can be said to be basically successful.

Otherwise, it is necessary to continue research to break through this requirement in order to realize the practical application of quantum computers.

"Academician Han, the fidelity measurement is over!"

Hearing the staff's words, everyone's heart was raised.

"What's the fidelity this time?" Han Shubin asked.

"The fidelity of single-bit gates is 99.99%!"

"99.99%?" Han Shubin asked in surprise.

Even though Han Shubin was mentally prepared, he did not expect that after adding Xu You's set of quantum error correction codes, the fidelity of the single-bit gate could be so high.

Such a high single-bit gate fidelity has never been seen in quantum computers around the world.

What's more, it is still in the case of such a high number of qubits.

Xu You was also somewhat unexpected about this.

It seems that this time, the practical application of superconducting quantum computers is really coming.

According to common sense, the fidelity of the single-bit gate can be so high, so the fidelity of the double-bit gate will not be bad.

Of course, everything still depends on the final result.

"What is the fidelity of the double-bit gate?" Han Shubin continued to ask.

At this time, there was a slight tremor in Han Shubin's voice.

"Academician Han, the fidelity of the double-bit gate is 99.84%!"

"99.84%!"

Hearing this value, Han Shubin couldn't help shouting.

Such a high double-bit gate fidelity once again created a new record.

Even those quantum computers with only a dozen or twenty qubits cannot achieve such a high fidelity of double-bit gates.

This means that we not only calculate faster than them, but also calculate more accurately than them.

Even, because of the discovery and application of new superconducting materials, we can achieve superconductivity at higher temperatures.

In this way, we have taken a big step ahead in terms of cost control.

After learning of this result, the staff in the laboratory were very excited.

They have been fighting for too long in the field of quantum computers.

During this period, only they themselves know the efforts they have made and the setbacks they have experienced.

At this time, Han Shubin looked at Xu You with respect in his eyes.

The success of this experiment is the hard work of the whole team, but it is also the success of Xu You.

Although Xu You alone would definitely not be able to create a quantum computer.

But without Xu You, in another five years, or even ten years, I'm afraid we won't be able to reach this level.

Xu You is really the kind of talent who can change the entire technological landscape by himself.

"Xu You, thank you for your contribution to the Island Project! I will report all your achievements to the higher authorities. Don't worry, the honors and rewards you deserve will not be missing at all!"

"Yeah, if there is no Xu You, we really don't know when we will get a breakthrough. This time, we have already set a new world record in terms of computing speed, fidelity, and energy consumption control. Those quantum computers in the United States can’t keep up with ours!”

"Our new generation of young researchers in Huaxia is really outstanding. With a researcher like Xu You here, why worry that Huaxia can't reach the top of the world?"

At this moment, Xu You was also very excited.

The reason why Xu You was excited was not only because of everyone's praise, but also because the island project had achieved initial success.

Because of the confidentiality of the project, Xu You will not become famous all over the country and the world again because of this.

But for Xu You, this is already a very significant event.

Xu You believes that this is not the pinnacle of his scientific research career, but perhaps just the beginning.

Xu You will continue to use his own efforts to enable China and even all mankind to achieve new breakthroughs in science and technology.

After that, the project team continued to carry out various optimization work for the new generation of superconducting quantum computers.

Wait until all the details are optimized and pass the test.

This generation of superconducting computers can be assembled and officially entered into practical use.

...

Just when the island's new generation of quantum computers had just completed testing and assembly.

From the IBM Corporation in the United States, a big news was released.

IBM's next-generation quantum computer, code-named "Osprey", was officially released today.

This news caused heated discussions all over the world.

"Oh my God, the number of qubits of IBM's new generation of quantum computer - Osprey has reached 433! Such a number of qubits is more than three times that of the previous generation of Eagle!"
