Chapter 233: Accidentally Falling into a Trap On the sofa, after making the threat, Song Yao kissed Xu Qingzhou on the face several times before letting him go with satisfaction. She snorted softly, with an expression as if she had finally avenged herself, and turned back to the house. "Ah~" Xu Qingzhou let out a long breath. He was threatened and pressed on the sofa, and his face was covered with saliva. He was used to the former and had considered it when he was with Song Yao. In any case, he would definitely not let Song Yao go. As for the latter, he was pressed on the sofa and forcefully kissed, and no matter how you look at it, he didn't seem to suffer any loss. It's just a bit insulting. After thinking for a while, Xu Qingzhou stretched, got up and went back to the bedroom to sleep. If nothing else, he would definitely sleep comfortably tonight. In the bedroom, Song Yao couldn't sleep and sat on the edge of the bed. When she thought about how she used her feet to help Xu Qingzhou relieve stress, she felt her face burning. Except for this time, she even dared to kiss Xu Qingzhou outside. Her expression became serious. She felt something was wrong and thought carefully about the time they had spent together.
The two of them were officially together. They held hands for the first time. They touched each other's legs in different ways, kissed each other, and then she got used to Xu Qingzhou's kisses and hugs. Song Yao pursed her lips and suddenly became enlightened. It turned out that something was wrong here. She seemed to have fallen into Xu Qingzhou's "claws" little by little. This guy was pulling her bottom line down without anyone noticing. Although most of the time she was willing to be "cheated" by this guy and regarded it as a small benefit for him. But it's still very infuriating. Then, the sound of banging was heard in the room. The night passed. What happened last night was just a simple episode. The two young people tacitly agreed not to mention it. After washing up, they held hands and went to the school cafeteria to have breakfast, and then leisurely found an empty classroom. The library is too crowded and there is no comfortable classroom. I had made a small start yesterday, and without having to think about the ideas, Xu Qingzhou took out the manuscript paper and immersed himself in calculations. The information sent by Professor Zhong did not have much reference value for Xu Qingzhou. No matter how cutting-edge the content is, can it compare to the knowledge he has here? There were not many people in the classroom. In addition to Xu Qingzhou and Song Yao, there were three other girls. Xu Qingzhou felt that they looked familiar, but he didn't pay much attention to them and concentrated on his calculations. Behind them, three girls started chatting in the small group again. Rhea: "Xu Qingzhou and Song Yao meet again, are we the witnesses of love?!" It was Xiaoxi: "That's great, a relationship where we are both equally matched." Rhea: "But I don't feel much love in them. Look, both of them are so rational. They are not like other couples who stick together all day long." Danzai: "This might be the love between top students." It was Xiaoxi: "I think that the love between these two people is probably not like that between us mortals. They are more likely to have spiritual communication." Rhea: “That makes sense.” Time passed very quickly. After finishing two sheets of manuscript paper, Xu Qingzhou stopped to rest. Next door, School Beauty Song was reading a book. When she was serious, her face was cold, and the air pressure around her seemed to drop.
The weather was very good, with bright sunshine and gentle breezes. Sitting in the classroom, I could occasionally smell the faint scent of freshly cut grass. The breeze in the classroom blew through, lifting a few strands of hair in front of her forehead, and then she took the trouble to hook them behind her ears. Everything looks beautiful. He couldn't help but take out his cell phone and took two pictures. Who would have thought that the famously cold and aloof Song University campus beauty would actually do such a thing last night? Is this a loss of morality or the extinction of humanity? "Are you taking pictures of me?" Song Yao turned her head to look at him, her voice clear and cold. Xu Qingzhou handed over the phone, "Is it okay?" Song Yao glanced at her own photo and nodded her chin. "I look very good." "School Beauty Song is not modest either, what are you doing?" "Set it as your wallpaper." Danzai: "Help, I'm dying!" It was Xiaoxi: "This is the love I want!" Rhea: "After falling in love, even Song Yao has become like an ordinary girl" At the back of the classroom, three girls started chatting again. Xu Qingzhou had been dealing with the problem of quantum decoherence all morning. Although he had the idea before, the current quantum satellites and ground receiving equipment are still far behind those in a decade or so in terms of accuracy and stability. It's a bit difficult to adapt to the local environment if we just copy the old ways. For example, the formula quantified by the "decoherence rate" γ, because when the indblad equation was used to describe it, the quantum bit state output by the advanced quantum satellite was referenced. For the current first-generation satellites, the rate attenuation calculation formula of the off-diagonal coherence term a(t)b^*(t)a(t)b(t) will become invalid. It is always necessary to re-evolve and derive various formulas. At noon, the two went to the Farm Restaurant together. After finishing his meal, Xu Qingzhou discovered that his landlord Aunt Jia had actually sent him a message on WeChat. Looking at the more than 30-second voice message, his head ached and he turned back to the text message. "Xiao Xu, the weather is getting hotter and hotter. Do you need auntie to help you install an air conditioner in the second bedroom?" Install air conditioning? Xu Qingzhou thought to himself that it was a close call and fortunately he did not click on the voice play button. Haha, Auntie, you are a very nice person. He refused without even thinking about it. Sorry, we both have cold body and are afraid of cold. Aunt Jia naturally agreed happily. The reason she asked was because her best friend was recently disliked when she rented out her house because it didn’t have air conditioning. It’s been rented out for a month and still hasn’t been rented out. According to the original plan, the second bedroom was also to have air conditioning, but later my son said he would not come back, so in order to save money, it was not installed.
It seems that this money cannot be saved. Young people nowadays have higher demands for quality of life. Rejecting the aunt's kindness, Xu Qingzhou carefully glanced at the girl opposite him and saw that she was drinking soup in small sips. After finishing, she looked at her own mobile phone and didn't notice him, so he secretly breathed a sigh of relief. This may be the standard reaction of boys after doing something they feel guilty about. Even though he knew that it was impossible for the girl to see his phone screen, this expression still appeared on her face. Could it be that she had discovered it? Some boys even had to ask indirectly: Xiao Song, our landlady is very nice. Then see if the landlord also sent this message to Song Yao. After thinking it through, Xu Qingzhou made up his mind, calmly deleted the chat history with Aunt Jia, and put down his phone. Not only that, he even managed to turn the tables and asked Song Yao, "What are you looking at? Your brows are furrowed." “The market is still rising.” It turns out that it’s not about installing air conditioning. Xu Qingzhou smiled and asked, "Do you regret throwing it away too early?" Song Yao shook her head and said confidently: "I still stick to my point of view. The current trend is not normal." "Yes, but many people are still immersed in the dream of getting rich." Xu Qingzhou sighed, but Song Yao remained silent. After they finished their meal, they returned to the classroom to continue their self-study. The process was cumbersome, but Xu Qingzhou still solved the decoherence problem before dinner. In the evening, he made a concerted effort to solve the matrix problem as well. The general idea is to use Chebyshev polynomial expansion, which is accurate and simple to calculate, and finally use parallel computing and distributed computing technology to speed up the calculation process. For a two-level system, its Hamiltonian can be expressed as: [ H =\frac{\hbar\omega}{2}\sigma_z ] ,\omega ω is the angular frequency of the system, \sigma_zσz is the z component of the Pauli matrix, expressed as: [\sigma_z =\begin{pmatrix} 1 & 0 \ 0 &-1 \end{pmatrix}] Song Yao looked at her boyfriend who was not careful with her, and reminded him before going to bed: "Go to bed early." "Okay." Xu Qingzhou said without raising his head. "." So perfunctory. Song Yao looked at Xu Qingzhou who was lowering his head, sighed in her heart, and understood her mother's helplessness more and more. (End of this chapter)
