Chapter 356: Indecisiveness, Quantum Mechanics On August 8, the heat in Chengdu was very intense, at Chengdu Tianfu Airport. A young couple walked out of the passage, the girl was carrying a cat bag in her arms and walking briskly, while the boy was pushing two large suitcases. "Xu Qingzhou, walk faster, can you do it?" "." Xu Qingzhou had a gloomy face and wanted to say that he didn't know who was begging for mercy in the groaning last night. Song Yao snorted lightly, and suddenly she understood why Xu Qingzhou was usually so mean. I just like the feeling of you not being able to stand me but being able to do nothing about me. "It's a familiar heat wave." As Xu Qingzhou walked out of the airport hall, he could feel the heat blowing towards him. Song Yao held Er Miao in her arms, looked at her phone, turned around and said, "My dad said it will take another 10 minutes."
As usual, on the first day they returned home, the two families gathered together for a simple meal. Due to the nature of his work, Old Song had relatively free time, and he was on a field trip. Xu Qingzhou nodded and squinted at the green spots in the distance. When he left, the wind was biting cold, and when he came back, the summer was scorching. Their birthdays were in early July and early August respectively, and they are both 7 years old now. Unlike the summer in the north, the heat in Chengdu is like locking people in a huge cage, stuffy and hot. Song Yao took out her cell phone and took two group photos with Xu Qingzhou, and then took some beautiful photos by herself. Xu Qingzhou sat on the suitcase, looking at the selfie of the school beauty Song, and felt dazed. It was the summer vacation of his senior year in high school. At that time, she was still a cold and arrogant goddess, but now she is becoming more and more down-to-earth. Tsundere, cold, violent, and weird. Song Yao seems to have collected all of these. After Song Yao finished posting on her Moments, she turned around and saw Xu Qingzhou staring at her like a fool. She walked over and fixed his hair, "Teacher Xu, are you impressed by my beauty?" As summer approached, Xu Qingzhou cut his hair shorter, which led to Song Yao doing her hair up when she had nothing to do. Song Yao looks as beautiful as ever, wearing a white T-shirt and a denim skirt. Even though the two of them often stay together, they still look amazing. It was indeed pretty, but Xu Qingzhou always liked to play tricks, and commented: "When you fake smile, what about your eyes, nose, and mouth? Your facial features have their own ideas." pia~ Someone with a bad mouth got hit by a palm strike from Tathagata. At this moment, a black seven-seater car appeared in sight. The middle-aged man got out of the car. "Dad~" "Uncle Song~" Song Shisong nodded, his eyes swept over the two young men, his serious expression showing a hint of smile: "You must be anxious waiting, the road was jammed for a few minutes." Song Shisong sighed, these two young people seemed to be more and more suitable for each other. When he drove here just now, he saw his daughter beating Xu Qingzhou from a distance.
If a father says he doesn't feel resentful when he sees his cabbages being taken away by someone else, he would be lying. Even if the pig that took the cabbages was very good, he would still feel a little unhappy. Seeing these two people getting along, he felt inexplicably relieved. Both he and Zhang Junli were busy, and because of work, they inevitably brought a serious atmosphere home, which also caused Song Yao's personality to become a little cold. Look, this is the personality a 20-year-old girl should have, lively and active. However, it seems a little bit violent. He nodded in appreciation in his heart, well, this boy is good, he knows how to tolerate girls' little temper. "No, we just came out a while ago." Xu Qingzhou said as he and Song Shisong stuffed the suitcases into the trunk. Three people get in the car. Song Shisong started the car and said with a smile: "Xiao Xu, I heard from Xiao Yao that you have been doing physics experiments recently?" "Yes, I encountered some obstacles in mathematics, so I planned to change direction." Xu Qingzhou sat in the co-pilot seat, Song Yao sat in the second row, and Ermao was also let out of the bag by Song Yao, and was lying listlessly in her arms. "We don't understand math, physics, or anything like that. I think your research is just like us solving cases. Sometimes the clues are lost, and sometimes there's not enough evidence. But these are normal." "Yes, let's put it aside for now so as not to get stuck in a dead end." During this period, Xu Qingzhou spent most of his time collecting data and making models, and occasionally studying the problem of stuck local smoothness. The data on quantum entanglement was also obtained smoothly. The day after the meeting, he received a call from Professor Chang, asking him to go to the Quantum Research Institute to retrieve data. By introducing parameters such as electromagnetic potential and the phase of the wave function, and taking into account the interaction between them, he has now figured out the model of the wave function phase change. A mathematical model of coherence in quantum entanglement is nearing completion. After both models are established, there is another very important step, which is to explore the mechanism of how the wave function coherence in the AB effect is transmitted to quantum entanglement. This requires considering the influence of electromagnetic potential on the wave function of entangled particles and how this influence leads to changes in the state of entangled particles. It is also necessary to analyze the transmission process and laws of coherence in quantum entanglement and how it affects the coherence of entangled particles. At 6: in the evening, the two families met in a private room of the hotel. The atmosphere was certainly good. The two pairs of parents knew each other so well that it didn't even matter whether Xu Qingzhou and Song Yao were there or not. "Lao Xu, a friend of mine has a fishing pond. Let's go there together when we have time?" "Hey, that's just right, I just bought a new pole." Xu Shouyun and Song Shisong talked about everything from the development of the country and society to street management, and finally to fishing. They gradually became "quasi-fishing friends" on the basis of "quasi-relatives". Wang Xiaping and Zhang Junli's topics were even wider, ranging from policy issues to daily necessities. Xu Qingzhou was amazed repeatedly, realizing that with the foresight of Old Xu and the others, they must have contacted Song Yao's parents a lot. It was not until 9 o'clock in the evening that the family returned to Wutong Community. The layout of the house has not changed much, and the bedroom is more obviously evolving into a storage room. The bed is still covered with the gorgeous peony quilt cover, which makes Xu Qingzhou's head hurt. After Xu Qingzhou put away his luggage, the family sat in the living room to watch TV and hold a small meeting. Wang Xiaping expressed her worries: "You will go abroad after completing your master's degree this year. What happened between you two?"
Long-distance relationships are difficult, let alone relationships across borders. Xu Qingzhou picked up an apple and took a bite of it since it was washed. He smiled and said, "Song Yao and I have already discussed this. I'm going to MIT and she's going to Harvard. The two schools are not far apart, so we can see each other in less than half an hour." "It seems that you have all planned it out." Xu Shouyun nodded, feeling a little emotional. Unconsciously, this kid had already considered things comprehensively and long-term. "It's okay as long as you know the answer in your minds." Wang Xiaping was most worried about this. When the two families had dinner together, they deliberately avoided this topic because they wanted to ask the two children about their plans in private. "As for the relationship issue, your mother and I were worried about that, and now we're relieved. The second question is about the two of you going abroad - do you plan to stay abroad forever?" Wang Xiaping also looked at Xu Qingzhou. "No." Xu Qingzhou answered decisively. "That's right. Why would a good Xia countryman go abroad and settle down in a place where he is unfamiliar with the environment?" Wang Xiaping nodded in agreement. Having watched this kid grow up, she knew that this brat would not like living in a place full of foreigners. She continued, "Xia Country is developing very well now. Twenty years ago, no one would have thought that Rongcheng would be as prosperous as it is today." "That's right. Xiaguo's development in recent years has attracted worldwide attention, and the environment is also getting better. Coming back is a good choice." Xu Shouyun nodded slightly. As parents, they certainly didn't want their son to go abroad and never come back. If Xu Qingzhou was determined to go out, they would not support him, but they would not object either. Children, you have your own path to follow. Xu Qingzhou ate an apple, smiled, and said, "A nest of gold or silver is not as good as your own doghouse. No matter how good the outside world is, it is not as comfortable as your own hometown." "Wait until you and Xiaoyao come back from school, then get married and have a child. I saw the kid from Xiao Zhang's family a few days ago," Ms. Wang began to imagine. "Mom, stop for a moment." Xu Qingzhou interrupted quickly and reminded: "Song Yao and I haven't even gotten married yet, how come it's the child?" “I just plan ahead.” "You're too early. We're only 20 years old." "Look, you two are both 20 years old. Two years will pass in the blink of an eye. In the blink of an eye, won't you two be married?" Xu Qingzhou curled his lips and said, "Even if we get married, what's the point of having children? It's not fun." "Are children born to play?" Wang Xiaping stared. "." Xu Qingzhou sighed and threw the apple core into the trash can without dwelling on the issue: "It's still early." Wang Xiaping thought about it carefully and realized that although it was true, it seemed a little early to consider having children. "You were working on that quantum stuff a while ago. Is it dangerous?" She searched and looked into this quantum stuff, it's very mysterious. "That thing has no radiation." "I'm not talking about radiation, but... like explosions or black holes or something like that. Anyway, it's scary."
"." Ms. Wang must have been reading some fake science again. The next day is Saturday. After lunch, Lao Xu went out with his fishing rod, planning to cast a few times and add a fish to tonight’s table. Xu Qingzhou went to buy a new set of bed sheets, washed them in the morning, and hung them out to dry. After a day of exposure to the sun, they would be dry by the evening. After washing the sheets, Xu Qingzhou laid them out at home. Wang Xiaping made an appointment to play mahjong with her old friends. Outside the window, cicadas chirped and sunlight fell on the windowsill. Xu Qingzhou lay on the sofa with his eyes closed, planning to take a nap first and then get up to read some information. Perhaps it was the first day Xu Qingzhou returned home, Wang Xiaping did not forget that she had a son at home. Just at 4 o'clock, Ms. Wang came back with vegetables. He was very happy, it seemed that he had won a huge sum of more than 5 yuan today. Xu Qingzhou leaned against the kitchen door, watching his mother happily take out pork ribs, shrimps and other things. "Don't stand there, come over here and peel the garlic." "okay." After peeling the garlic, Xu Qingzhou was driven out of the kitchen. It was afternoon and the sun was not so scorching, so he simply went to the balcony to bask in the sun. After lying on the rattan chair on the balcony for about ten minutes, I vaguely heard a knock on the door. It was obvious that Lao Xu was back. As soon as Xu Qingzhou stood up, he saw Wang Xiaping opening the door, mumbling, "Old Xu is back, and he didn't bring his key again." Xu Shouyun came in with a fishing rod on his back and a plastic bucket in one hand. Wow~ What a good catch. Xu Qingzhou was a little surprised. Judging from the force on the plastic bucket, it was a big fish. Then he saw his father bending down and taking out a plastic bag from the bucket. Inside was sliced fish fillets, and “×× sells fish” was written on the plastic bag. Overestimated Lao Xu. "." Seeing Xu Qingzhou's strange expression, Old Xu coughed dryly, and felt the need to clear his name, and said: "I still caught a few, small fish, so I let them go." Xu Qingzhou nodded, indicating that he believed in the Air Force boss's final stubbornness. After dinner, he and Lao Xu sat together to watch the rerun of Xue Pinggui and Wang Baochuan. How should I put it? This was just like the short plays that were developed in the next few years. It would give people a feeling of "it's history, it's delicious". Of course, overall, this drama is countless times better than those short dramas. After watching two episodes of the TV series, Xu Qingzhou went back to his room to chat with Song Yao, and asked Song Yao if she wanted to go to the night market tomorrow night.
Song Yao: "Yes." Song Yao: "I have guests at home tomorrow, I don't know when I can come out." Xu Qingzhou: "Who is it?" Song Yao: "My uncle and his family have settled in Shanghai, and they are traveling during the summer vacation." 10 pm. Xu Qingzhou took out the manuscript he had written a few days ago and prepared to continue his work. Currently, he is still looking for tools to link the AB effect and quantum entanglement. The phase change of the wave function can be regarded as a transmission of quantum information. When two or more particles interact and form an entangled state, their wave functions are superimposed on each other and produce non-local correlations. In the AB effect experiment, although the particles do not directly pass through the magnetic field, the influence of the electromagnetic potential on the wave function can still be transmitted to the particle system that interacts with it, thereby forming an entangled state. Xu Qingzhou was constructing the connection between these two things in his mind. In terms of the phase change of the wave function, the wave function of a multi-particle system can be considered, that is, for each particle, its wave function can be expressed in complex form. Xu Qingzhou picked up the pen and started writing. [[\psi_i(x_i, t)=|\a_i(x_i, t)\right)]] For the entangled state, we also need to figure out a function that not only includes the product of the wave functions of each particle, but may also include the interaction terms and interference terms between multiple particles. Xu Qingzhou frowned, and after a moment he picked up the pen and wrote the five words "non-classical effect" on the manuscript on one side. Yes, in general, in addition to the classical electromagnetic interaction, we also have to consider the influence of non-classical effects on the phase of the wave function. These effects may include quantum tunneling, quantum interference, quantum entanglement, etc., which will lead to additional changes in the phase of the wave function. "Whoo~" Xu Qingzhou leaned back in his chair and let out a long breath. In this case, new physical phenomena and mathematical structures would have to be introduced. It became more and more complicated, and I unknowingly increased the intensity. Boom~boom~ Wang Xiaping came in with new sheets, muttering, "Such good sheets, but they had to be replaced with this thin layer of cloth, which is so expensive." "This person's material is good." Xu Qingzhou stood up and said, "I'll change it myself." "You go about your business." Wang Xiaping waved her hand and helped Xu Qingzhou change the bed sheets and quilt covers. She glanced at the things on the table that looked like ghost paintings, shook her head and sighed. "I think you will be like Old Sun's son sooner or later. You are so young, but your hair is less than that of a man in his sixties or seventies." "Mom, I often go to exercise and run now." Xu Qingzhou said, comparing the muscles on his arms, "Look, it's very obvious." "If it weren't for Xiaoyao, it would be you, who is always staring at ghosts. How could you go for a run?" "."
Xu Qingzhou was silent. (End of this chapter)
