Chapter 356: Visiting Huake University Again
In this quiet state of solitude, Xu You was able to adjust himself to the best.
After so many days of accumulation, Xu You's abilities have improved to varying degrees.
Even though his study level is still level five, Xu You's mental and academic abilities are much stronger than when he just reached level five.
Soon, Xu You entered a better flow state from a deep learning state.
This is the best condition Xu You has felt himself in so far.
In this state, Xu You quickly derived a series of related formulas, gradually approaching his ideal goal.
The expectation value of a quantum observable.
Measure the eigenvector corresponding to the operator.
The expected value of the four-body observation.
Xu You deduced each complex formula one by one.
I don’t know how much time passed.
Xu You finally finished writing the last equation.
"If I'm not mistaken... the maximum quantum violation value is this result."
Xu You is very confident in himself because over the years, every calculation he made has been very accurate.
Based on these formulas, Xu You designed the quantum circuit diagram of the experiment and made a plan for the entire experiment.
After completing all this work, Xu You came to the quantum physics laboratory again.
Wang Xiangwu was still resting and did not appear in the laboratory.
Before the experiment started, Xu You explained to everyone the main content of the experiment and some of the key points.
"This time, we are going to simulate the quantum nonlocality. This is the quantum circuit diagram we need to build. Next, we need to complete the preparation of entangled states, unitary evolution of quantum states, and quantum measurement."
Apart from what needed to be done in the experiment, Xu You didn't tell them much else.
After all, this is an experiment related to the Island Quantum Computer.
Even so, in order to ensure the confidentiality of the project to the greatest extent possible, Xu You still asked them to sign a confidentiality agreement.
After Xu You explained the steps and precautions of the experiment.
The experiment officially began.
Because Xu You has completely designed the quantum circuit diagram for this experiment.
The difficulty in the experiment lies mainly in the construction of the quantum circuit diagram and the final measurement.
In order to better conduct statistical comparison, the amount of data that needs to be measured in the entire experiment is very large.
If Xu You were the only one conducting the experiment, it would take an unknown amount of time to complete the construction of the quantum circuit diagram and the measurement of the data.
Fortunately, there are professional teachers and students to help Xu You conduct experiments.
This made the progress of the entire experiment very ideal.
After completing the measurement of hundreds of sets of experimental data.
Xu You began to organize the data himself.
Xu You derived the formula based on his own data and all the measurement results.
An actual quantum violation value was calculated.
"Sure enough! The experimental measurement value and the theoretical estimate are almost completely consistent!"
After completing the final calculation of the quantum measurement experimental values.
Xu You could finally be sure that all his theoretical deductions were correct.
In this way, Xu You can perform quantum programming on the optimization selection problem according to this theory.
Afterwards, Xu You contacted Han Shubin and informed him of the achievement.
"Optimization selection problem... Professor Xu, do you have any specific choice at the moment?"
"The details have not yet been determined. After all, we have only completed the theory now, so it is best to familiarize ourselves with the new quantum optimization device architecture."
In order to determine the specific direction of the problem, Xu You thought it would be better for Xu You to work with the quantum computer.
After listening to Xu You's words, Han Shubin also understood what Xu You meant.
"Professor Xu, it's like this. Our island quantum computer has very strict requirements on many environmental factors, and it's really not convenient to move it. If possible, you can come to our Huazhong University of Science and Technology to conduct research."
It is not realistic to transport the island quantum computer to Jijing University, so Han Shubin can only express this idea to Xu You in a tactful way.
"I understand, Academician Han. Then when I have time, I will come to Huake Institute to bother you."
"Don't bother, you're always welcome."
Xu You still remembers that because Jijing University's level in engineering was not outstanding, Xu You had tactfully asked Han Shubin to allow him to go to Huazhong University of Science and Technology to learn some cutting-edge knowledge in engineering.
At that time, Xu You was just a novice in scientific research. He had only published two papers and had not achieved any significant achievements.
Even so, Han Shubin readily agreed to Xu You's request.
However, due to time constraints, Xu You did not actually come to Huazhong University of Science and Technology to study.
On the appointed day, Xu You arrived at Huazhong University of Science and Technology escorted by three bodyguards.
Liu Jiao received Xu You very warmly and brought Xu You to the laboratory of the island quantum computer.
This was the second time Xu You saw the Island Quantum Computer.
Xu You still remembers that the last time he used the quantum error correction code he developed, the island quantum computer was able to perform calculations with very high fidelity.
When he saw the island quantum computer again, Xu You felt familiar but also shocked.
Unlike ordinary computers, the island quantum computer is very large, giving a huge feeling like an early computer.
Because the island quantum computer is a superconducting quantum computer, the temperature needs to be kept low at all times to maintain the operating environment of the quantum computer.
In addition to temperature, noise is also a condition that must be strictly controlled.
As long as the decibel value of the noise exceeds a certain level, it will greatly affect the operating stability of the quantum computer.
"Professor Xu!"
When he saw Xu You, Han Shubin greeted him warmly.
"Academician Han, we meet again."
In addition to Han Shubin, Xu You also met with software department engineers Chang Xiaoping and others, with whom he had worked before.
"Professor Xu, I have some other things to deal with here. If you have anything, just talk to Chang Gong first."
"Okay, Academician Han, go ahead and get busy."
Xu You and Chang Xiaoping are also quite familiar with each other. They had previously collaborated for a period of time on the research of quantum error correction codes.
In terms of software, Chang Xiaoping is even more professional than Han Shubin.
"Professor Xu, I heard from Academician Han that you have solved the problem of non-locality of quantum bit systems?"
"Well, it has been solved theoretically, and the experimental measurement results are completely consistent with the theoretical values. Of course, whether it can be finally applied depends on the feedback from actual programming."
In previous quantum programming experiments, Xu You did not use a quantum computer, but only conducted experiments with a relatively simple quantum circuit
