Chapter 209 Fortunately, this is our Chinese talent
Because in the real process of quantum information transmission, quantum bits will inevitably be interfered by noise, resulting in errors.
Therefore, it is very important to measure the transmission error rate of quantum error correction codes under various noise conditions.
After Xu You made all the preparations for the experiment, he started it.
Under the same noise decibel level.
Xu You needs to measure the transmission error rates of multiple different quantum error correction codes and make a single factor comparison.
If my quantum error correction code can show a lower transmission error rate under different noise decibels.
This 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 error rate graphic curves of each error correction code can be synchronously displayed on the computer software.
As the experiment progressed, Xu You became more confident.
Under the first noise decibel value, Xu You's quantum error correction code showed the lowest error rate.
This proves that this set of quantum error correction codes has at least certain highlights in error correction performance.
When other noise values are changed and the experiment is continued.
Xu You's quantum error correction code still performs very stably.
The lowest error rate is maintained under different noise values.
Until the noise level is high enough.
The error rate of this set of quantum error correction codes has risen sharply.
Even so, its error rate is still the lowest among several quantum error correction codes.
Moreover, such high noise values are almost impossible to exist in real quantum computer operations.
Just keep the noise low enough.
Xu You's quantum error correction code can almost guarantee the accuracy of information transmission.
Xu You was not satisfied with this and immediately submitted his results to Han Shubin.
Xu You felt that there was still room for improvement.
After that, Xu You further optimized his own set of quantum error correction codes based on some new ideas, striving to ensure a lower error rate.
In addition, Xu You also set up a quantum key distribution protocol.
If there is an eavesdropper, he will get various different results randomly, and the state of the quantum bit substring will definitely change.
In this way, not only will the eavesdropper be unable to determine the correctness of the measurement results, but the eavesdropper's presence will also be quickly exposed.
After re-measurement, this time, the error rate of Xu You's quantum error correction code became lower under various noise conditions.
Xu You can finally submit this result to Han Shubin.
Xu You contacted Han Shubin again through Liu Jiao and arranged a meeting time.
At the appointed time, Xu You brought his computer to Han Shubin's office.
Han Shubin felt a little anxious when he saw Xu You.
"Xu You, did you really edit a more practical quantum error correction code so quickly?"
"That's right, Academician Han. The data is all in my computer. 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 ideas, why he coded in this way, and the derivation of various formulas, etc.
Listening to Xu You's story, Han Shubin couldn't help but look at Xu You with admiration again.
Han Shubin's abilities and qualifications are among the best in the whole of China.
Even in the world, Han Shubin is a very famous scientist.
Even so, Han Shubin concentrated his attention and used his brain at full speed to barely keep up with Xu You's thoughts.
"Awesome, awesome! With this 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 that currently exist in quantum computers.
But it is undoubtedly a solid step towards the practical application of quantum computers.
Looking at Xu You, Han Shubin's eyes were filled with mixed emotions.
Xu You started studying quantum error correction, and a new result was born.
All in all, it only took a dozen days.
Although Xu You did not start his research from scratch, many of his previous achievements have been of great help to the research on quantum error correction.
But this speed is indeed too fast.
If this continues, Xu You will contribute nearly half of the power for the new generation of quantum computer technology.
Han Shubin was only glad that such talents were born in China rather than other countries, and did not choose to go abroad for scientific research.
Otherwise, the consequences are really unimaginable.
"Xu You, go back and organize this result and send it to me in PDF format. I will help you apply to include it in the results of the island plan. You can also study quantum chips when you have time. Of course, this process must be more complicated and involves a lot of industrial preparation knowledge. You definitely can't do it alone. Let's discuss any ideas together."
"Okay, Academician Han, I will contact you as soon as I have any ideas."
After that, Xu You's quantum error correction code was successfully approved and was included as part of the island plan.
This is also the third achievement Xu You has contributed to the island project.
When the new generation of quantum computers is successfully manufactured, Xu You will be truly qualified to say that this is the quantum computer he participated in manufacturing.
And under this achievement, Xu You also specially marked the name of "Jiliang Quantum Physics Laboratory".
After all, Xu You was conducting experiments here, and he couldn't just use the experimental equipment for free and take all the credit for the results.
Wang Xiangwu didn't know about Xu You's move, and was a little confused when he received this information.
After a while, Wang Xiangwu realized that this was the result that Xu You had produced when he said he wanted to do an experiment in his laboratory last time.
"Hey, he just used the equipment, but he also put our lab's name on it. This Xu You..."
Although he said this, Wang Xiangwu was still very happy in his heart.
No matter what, this is also helping to increase the results of my own laboratory.
However, Wang Xiangwu would not accept a single cent of the bonus for the achievement, and transferred all of it to Xu You's bank account.
After receiving the full 1 million project bonus, Xu You contacted Wang Xiangwu.
"Teacher, please at least deduct the lab equipment usage fee. You can't use the equipment for nothing."
"Don't make a fuss, it's just a little electricity bill. At most you can treat us to a meal later."
