When the matter of quantum error correction codes was mentioned, Xu You finally reacted.

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

"The previous set of quantum error-correcting codes are still used, so the fidelity is still a bit low. However, when the number of qubits has increased nearly twenty times, such a high fidelity can only be achieved.

It is said that the new control line circuit you designed has achieved very good results."

This is also the reason why Han Shubin did not want to create a large number of qubits before.

Although each additional qubit doubles the potential power of the 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.

"Xu You, since you edited the set of quantum error correction codes, I'll ask you to help with this part of the work."

"Okay, Academician Han."

Xu You also had this intention, so he, Han Shubin, Chang Xiaoping and others started working on quantum error correction 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.

Within a few days, the quantum error correction code was improved and adapted well to the new generation of quantum chips.

After the work on the quantum error correction code was completed, Han Shubin organized the second measurement experiment.

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

There is no difference between the time taken this time and the last time, it still only takes about 3 seconds.

Quantum error correction codes will not affect the computing speed of quantum chips, but will reduce the transmission error rate.

The next fidelity measurement experiment is crucial.

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

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

Otherwise, continued research is needed to break through this requirement in order to realize the practical use of quantum computers.

"Academician Han, the fidelity measurement is over!"

Hearing the staff's words, everyone's hearts lifted.

"What is the fidelity this time?" Han Shubin asked.

"The fidelity of a single-bit gate is 99.99%!"

"99.99%?" Han Shubin said in surprise.

Even though Han Shubin was mentally prepared, he really didn't 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 high single-bit gate fidelity has never appeared in quantum computers around the world.

What's more, when the number of qubits is so high.

Xu You was also a little unexpected about this.

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

According to common sense, if the fidelity of a single-bit gate can be so high, then the fidelity of a two-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 hint of trembling 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 but exclaimed.

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

Even those quantum computers with only a dozen or twenty qubits cannot achieve such a high two-bit gate fidelity.

This means that not only can we calculate faster than them, we can 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 are also a big step ahead in terms of cost control.

After learning the results, the staff in the laboratory were very excited.

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

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, his eyes full of respect.

The success of this experiment is the result of the efforts of the entire team, but it is also Xu You’s success.

Although Xu You alone will definitely not be able to build a quantum computer.

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

Xu You is really the kind of talent who can change the entire technological landscape on his own.

"Xu You, thank you for your efforts in the island project! I will report all your results to the superiors. Don't worry, you will receive no less honors and rewards!"

"Yes, without Xu You, we really don't know when we will achieve a breakthrough. This time, we have set a new world record in terms of computing speed, fidelity, and energy consumption control.

Those quantum computers in the United States can’t catch up with ours!”

"Our new generation of young scientific researchers in China are really outstanding. With researchers like Xu You here, why worry that China cannot be on top of the world?"

At this moment, Xu You was also very excited.

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

Because of the confidentiality of the project, Xu You will not become famous nationwide and around the world again.

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

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 scientific and technological breakthroughs.

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

Wait until all details are optimized and passed inspection.

This generation of superconducting computers can begin to be assembled and officially put into practical use.

…

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

A big news was released from IBM in the United States.

IBM's new generation quantum computer, codenamed "Osprey", was officially released today.

This news caused heated discussions around the world.

"Oh my god, IBM's new generation quantum computer, the Osprey, has a qubit count of 433! This number of qubits is more than three times that of the previous generation Eagle!"
