Because in the real quantum information transmission process, qubits will inevitably be disturbed by noise, thus

An error is generated.

Therefore, it is very important to measure the transmission error rate of quantum error correction codes under various noise conditions.

After Xu You was ready for the experiment, he started the experiment.

In the case of the same noise decibel.

Xu You needs to measure the transmission error rates of various quantum error-correcting codes for single-factor comparisons.

If my own set of quantum error-correcting codes can show a lower transmission error rate under different noise decibels.

That is enough to show that Xu You's quantum error correction code is a more practical quantum error correction code.

After connecting the device to the computer, the computer software can simultaneously display the error rate image curves of each error correction code.

As the experiment progressed, Xu You became more confident.

In the case of the first noise decibel value, Xu You's set of quantum error correction codes showed the lowest error rate.

This proves that this set of quantum error correction codes has at least some bright spots in error correction performance.

And when replacing other noise values, continue the experiment later.

Xu You's set of quantum error-correcting codes is still very stable.

In the case of different noise values, the lowest error rate is maintained.

until the noise level is high enough.

The error rate of this set of quantum error-correcting codes has risen sharply.

Even so, its error rate is still the lowest among several quantum error-correcting codes.

Moreover, such a high noise value is almost impossible to exist in real quantum computer work.

Just keep the noise low enough.

Xu You's set of quantum error-correcting codes can almost guarantee the accuracy of information transmission.

Xu You was not satisfied with this, and immediately submitted his achievement to Han Shubin.

Xu You felt that there was still room for improvement.

After that, Xu You further optimized his set of quantum error correction codes based on some new ideas of his own, striving to ensure a lower error rate.

In addition, Xu You also set up a quantum key distribution protocol.

If there is an eavesdropper, the eavesdropper will randomly get various results, and at the same time, the state of the qubit string must also change.

In this way, not only the eavesdropper cannot obtain the correctness of the measurement result, but also the existence of the eavesdropper will be quickly exposed.

After re-measurement, this time, the error rate of Xu You's quantum error-correcting code has become even lower under various noise conditions.

Xu You can finally submit this achievement to Han Shubin.

Through Liu Jiao again, Xu You contacted Han Shubin at the agreed meeting time.

When the appointed time came, Xu You brought his computer to Han Shubin's office.

When Han Shubin saw Xu You, he felt a little anxious.

"Xu You, did you really edit a set of more practical quantum error correction codes so quickly?"

"That's right, Academician Han. The data is all in my computer, and I'll show it to you now."

Xu You turned on the computer and showed Han Shubin his new set of quantum error correction codes and experimental data.

At the same time, Xu You was also explaining to Han Shubin his thinking, why he coded like this, and the derivation of various formulas, etc.

Listening to Xu You's narration, Han Shubin couldn't help but look at Xu You with admiration again.

Han Shubin's ability and qualifications can be ranked among the top in China.

Even in the world, Han Shubin is also a famous scientist.

Even so, Han Shubin concentrated his attention hard and ran his brain at full speed, barely able to keep up with Xu You's train of thought.

"Awesome, amazing! With such a set of quantum error correction codes, the problem of quantum error correction will be solved to a large extent!"

Even quantum error-correcting codes cannot solve all the problems existing in current quantum computers.

But it is undoubtedly a solid step for the practical application of quantum computers.

Looking at Xu You, Han Shubin had mixed feelings in his eyes.

Xu You started to study quantum error correction, but a new result was born.

Back and forth, it only took a dozen days.

Although Xu You did not start his research from scratch, many of Xu You's previous achievements are of great help to the research of quantum error correction.

But this speed is indeed too fast.

If this continues, Xu You will contribute nearly half of his power to the new generation of quantum computer technology.

Han Shubin is only fortunate that such a talent was born in China, not in other countries, and he did not choose to go abroad for scientific research.

Otherwise, the consequences are really unimaginable.

"Xu You, go back and sort out the results again and send them to me in PDF format. I will help you apply for inclusion in the results of the Sea Island Project. Quantum chips, you can also study it when you find time. Of course this The process must be more complicated, involving a lot of knowledge about industrial preparation, you can’t do it alone, let’s discuss together if you have any ideas.”

"Okay, Academician Han, I will contact you as soon as I have an idea."

After that, Xu You's set of quantum error-correcting codes successfully passed the application and was included as part of the island project.

This is also Xu You's third achievement in the island project.

When the new generation of quantum computer is successfully produced, Xu You is really qualified to say that this is the quantum computer he participated in the production of.

Under this achievement, Xu You also specially marked the name of "Ji Daquan Quantum Physics Laboratory".

After all, Xu You conducted experiments here, so he couldn't waste the experimental equipment and take all the results on himself.

Wang Xiangwu didn't know Xu You's move, and was a little dazed when he received this information.

After reacting for a while, Wang Xiangwu realized that this was the result Xu You made when he said he wanted to do experiments in his laboratory last time.

"Hey, I just used the equipment, and even put the name of our laboratory on it. This Xu You..."

Even though he said so, Wang Xiangwu was still happy in his heart.

Anyway, this is also helping my laboratory to increase the results.

However, Wang Xiangwu won't accept a single cent of the reward for the achievement, and it will all be transferred to Xu You's bank account.

After receiving all the 1 million project bonuses, Xu You contacted Wang Xiangwu.

"Teacher, at least deduct the equipment usage fee in the laboratory, and you can't use the equipment for nothing."

"Don't make a fuss, it's just a little electricity bill, it's a big deal and treat us to a meal later."
