Chapter 215 This is a once and for all research
Song Xiyun also realized that she was indeed a little drunk, nodded and said:
"Well, then I will take a little rest first. Wait for me Rest for a while, I'll clean up the kitchen."
"No, I'll just clean up the kitchen. You can just rest."
Ning Chen helped Song Xiyun to the master bedroom. After arriving in the room, Song Xiyun did not sit down immediately, but turned around and looked at Ning Chen.
When Ning Chen and Song Xiyun looked at each other, the atmosphere gradually became romantic.
Under the influence of alcohol, this atmosphere became even more aggravated.
Just as the two bodies continued to get closer, Ning Chen's cell phone rang.
Ning Chen had to break away from this atmosphere and took out his phone to look at it.
When Ning Chen saw the caller's information clearly, he knew that this must be an important call.
"It's Academician Yue calling. It seems that the calculations during this period have come to fruition." Ning Chenxin said.
Thinking of this, Ning Chen said to Song Xiyun:
"Song Xiyun, you take a rest first, I will answer the phone."
"Well, you go ahead."
Song Xiyun was a little disappointed that this romantic atmosphere came to an abrupt end, but Song Xiyun knew that Ning Chen must have research matters to deal with, and she would support Ning Chen's work no matter what.
After sighing softly, Song Xiyun lay on the bed and rested.
Ning Chen came to the study room, closed the door, and answered the phone.
"Academician Yue."
"Teacher Ning, the data we used to run with supercomputer have now come out with the results. I have sent the data to you for relevant data analysis. I have to ask Teacher Ning to help me with the work.”
“Academician Yue, you’re welcome, this is what I should do.”
After hanging up the phone, Ning Chen first went to Song Xiyun's bedroom and checked on Song Xiyun's condition.
What Ning Chen didn't expect was that Song Xiyun fell asleep in just a few minutes. It seemed that she was indeed a little too drunk.
Ning Chen saw that Song Xiyun's condition was not bad. After a short rest, she should be fine, so Ning Chen no longer worried too much.
After covering Song Xiyun with a thin blanket, Ning Chen gently closed the door and returned to his study.
After receiving the encrypted file from Yue Jiafeng, Ning Chen first decrypted the file and then analyzed the various data in the file.
After some analysis, Ning Chen could preliminarily determine that these calculation results have great application value.
Compared with previous aerodynamic analysis methods, these Navier-Stokes equations set by Ning Chen can not only complete various numerical calculations with higher accuracy, but also take into account more many practical factors.
Applying it to the aerodynamic simulation system of aircraft design can help aircraft research institutes design better aircraft solutions.
Perhaps because of his very strong brain power index, alcohol intake did not have a significant impact on Ning Chen's thinking ability. Ning Chen could still think about various problems very quickly and clearly.
After completing the data analysis work, Ning Chen organized the data into models, encrypted the final results and sent them to Yue Jiafeng.
...
Two days later, when it was time for Song Xiyun to return to Yanjing, Ning Chen drove Song Xiyun to the airport.
"If everything goes well, I will be able to graduate with my PhD in a few months. Teacher Ning, when I come to Shengzhou next time, we will be colleagues." Song Xiyun said sweetly.
Song Xiyun has published several good mathematics papers in the past two years. The results of the papers are sufficient for doctoral graduation, so graduation is not a big problem.
"Okay, Song Xiyun, I wish you a smooth graduation in advance. I'll be waiting for you at Shengzhou University."
After seeing off Song Xiyun, Ning Chen drove back to Shengzhou University.
“This time, it’s time to think about quantum computers.”
On the way back, Ning Chen thought about it in his mind.
After these days of study, Ning Chen basically studied all the knowledge about quantum computers that he could find, and he also had some ideas of his own about the design and development of quantum computers.
Ning Chen feels that if you want to completely solve the problems related to the existence and smoothness of the Navier-Stokes equation, you must rely on algorithms and computers, and the calculation speed of the computer is a very important factor. .
Studying quantum computers in order to solve a mathematical problem seems to be the opposite.
But Ning Chen didn’t think so. Especially after that exchange with Tao Zhexuan, Ning Chen increasingly believed that the development of computers might determine the upper limit of the development of mathematics.
And once the research on quantum computers achieves a major breakthrough, it will have a permanent effect. Not only mathematics, but also physics, chemistry, biology and other subjects will benefit from this.
After returning home, Ning Chen summarized the various information he learned about quantum computers and organized his own research and development ideas.
The first thing Ning Chen needs to determine is the development direction of quantum computers.
Although there are not many quantum computers on the market currently, the concepts of various quantum computers have been basically determined.
The quantum computer development directions that Ning Chen can try include superconducting quantum computers, optical quantum computers, ion trap quantum computers, topological quantum computers, etc.
Combining the advantages and disadvantages of these different types of quantum computers, as well as his own understanding of quantum computers in his previous life, Ning Chen quickly decided on his development direction.
“From a comprehensive analysis, the direction of superconducting quantum computers is better.” Ning Chenxin said.
Optical quantum computers have the fastest theoretical calculation speed, but this kind of quantum computer is difficult to program and perform general quantum calculations, and its practical value is relatively small.
The coherence time of ion trap quantum computers is longer. Because of the natural unity of particles, the impact of laser coupling will be weaker, but the expansion of the number of qubits will be more difficult.
Topological quantum computers have less strict requirements on temperature conditions and have a strong fault tolerance rate, but physical implementation is very difficult.
Although superconducting quantum computers are not as good as the other quantum computers mentioned above in some aspects, their overall performance is the strongest. They can perform quantum programming and general quantum calculations. They have also gone through the process in previous lives. It has been proven in practice that it is the most mature quantum computer technology.
In addition, Ning Chen’s achievements in the field of superconductivity can also be better applied in superconducting quantum computers.
After deciding on the direction of quantum computer development, Ning Chen checked the backpack interface of his system.
“There are only two brain simulation simulations left...but this time it must be used again.”
If Ning Chen did not rely on the system, it would be difficult for Ning Chen to do it in a short time. Time to find the ideal design solution.
Ning Chen does not want to push this project to five or even ten years, so at this time, Ning Chen can no longer be stingy with the number of simulations.
After adjusting his condition, Ning Chen said silently in his mind:
"System, start a brain simulation simulation!"
[Received, the number of brain simulation simulations has been started for the host]
At the same time as receiving the system prompt, Ning Chen entered that place instantly In the deep darkness.
Different from the previous simulations, this time Ning Chen needed to limit the simulation to a smaller scale and conduct simulations at the quantum level.
Such a simulation is very difficult, because even with the most precise electron microscope, humans cannot directly observe quantum states. They can only determine that quantum states are in different states by counting a large amount of observation data. The probability distribution diagram below.
Therefore, Ning Chen was not sure how to construct quantum in simulated space. He could only rely on his limited knowledge about quantum and his own imagination to try to construct quantum in simulated space.
After dozens of attempts, Ning Chen finally made some breakthroughs and successfully constructed the quantum state he recognized in the simulated space.
In fact, Ning Chen was not sure whether this was a real quantum state, but after some experimental tests, Ning Chen determined that these quanta basically conformed to the various physical laws of quantum mechanics.
One of the characteristics of this brain simulation space is that it has exactly the same physical properties as the real universe.
Therefore, Ning Chen can verify whether his analysis is correct through the various behaviors of substances he simulated.
After confirming that the material he simulated was very close to real quantum, Ning Chen began to try to construct a quantum computer.
Compared with classical computers, the biggest advantage of quantum computers is that quantum has the characteristics of quantum superposition state.
If it is a classic computer CPU, N bits can only store one state at the same time.
But in a quantum computer, an N-qubit CPU can store up to 2^N states at the same time.
Although, if you want to know the specific value of each of the 2^N states, you also need to perform 2^N calculations.
But if you only want to get the distribution of these states, you can use no more than N calculations to get the result.
In this way, quantum computers can be used to accelerate calculations at an exponential multiple when solving certain problems.
After continuous simulation and improvement, Ning Chen gradually found the state and obtained many sets of valuable data.
However, due to the complexity of quantum simulation, Ning Chen's mental energy consumption was very huge, and he soon fell into a state of lack of energy.
“No…just relying on the simulation data obtained now is not enough for me to complete the design of a quantum computer.”
Thinking of this, Ning Chen quickly thought about how to extend his time in the brain simulation state.
