Chapter 226: Developed?
2 minutes passed.
"Well, your method is very good. It corrects the problem of uneven calculation values." Professor Zhong stared at the blackboard and thought for a long time, nodded slightly, and was very surprised. Just now he said that Xu Qingzhou would probably need to adapt to the work here, but...
Today's young people are really fierce.
Before he finished expressing his feelings, his attention quickly returned to the blackboard, because Xu Qingzhou then simply wrote down his idea of expanding Hilbert space.
"This allows us to use the inner product operation of the Hilbert space, and the norm derived from the inner product defines the length or size of the vector."
Professor Zhong frowned and said, "The quantum state is fragile. Any tiny disturbance may lead to the loss of quantum coherence and quantum information."
"Yes, I have considered this as well."
Xu Qingzhou nodded, picked up the marker and started drawing on the blackboard.
“First, we can use error suppression methods to perform active feedback control to reduce the interference of environmental noise and device errors on the quantum state. Second, we can construct redundant information in the Hilbert space to detect and correct quantum bit errors.”
"."
Beside the two men, Deng Ziyi had recovered a little now, or rather, had already started to get excited, and was completely unable to keep up with Professor Zhong and Xu Qingzhou's train of thought.
She was a little hurt. She was still saying that she had the advantage in the morning, but the reversal came too quickly. Without any preparation, the blow came in front of her.
There are indeed such abnormal people in the world. Not to mention their terrible math skills, they are also ridiculously good at physics. Look, they can come up with formulas in the quantum field at will.
Xu Qingzhou and Professor Zhong discussed for half an hour and finalized the basic framework before starting the formal calculations.
"Okay, your idea is very good! I was worried that you couldn't keep up with the pace, but it seems that I was worrying too much."
Professor Zhong looked at Xu Qingzhou in amazement, and at the same time, with some excitement in his eyes, he said: "Then the part of rewriting the Schrödinger equation into the form of the time evolution operator is entirely up to you."
"No problem." Xu Qingzhou nodded with a smile.
"Let's get started. If there are any problems during the process, we can discuss it together." Professor Zhong directly treated Xu Qingzhou as someone of the same level.
The two of them then sat down and began to calculate.
Deng Ziyi sighed secretly, and before starting to sort out the data, she poured a glass of water for the two bosses.
The afternoon passed by with complicated calculations on sheets of manuscript paper.
"There is a lack of mature technical means for the preparation, measurement and verification of high-dimensional quantum states," said Professor Zhong with some regret.
"If we consider using different degrees of freedom of photons, such as orbital angular momentum modes, we can achieve the preparation of higher-dimensional quantum states."
Xu Qingzhou took a few bites of food, chewed it, and then said, "We can also use the state mapping method between the polarization and orbital angular momentum dual degrees of freedom to improve the accuracy and stability of the preparation."
"This method, well, might be very useful."
Deng Ziyi drank the tomato fried egg soup happily, Aba Aba, what does it matter if it’s quantum or not, the most important thing is to eat!
But He Dang, who sat next to her, was different. His expression was quite complicated.
Sometimes he was talking about constructing redundant information, and sometimes he was talking about the preparation of quantum states. You would think it would be fine if Professor Zhong was the only one producing, but why did Xu Qingzhou seem to be on equal footing with Professor Zhong?
Sit and discuss?
Xu Qingzhou and Professor Zhong ate relatively quickly, said goodbye to Deng Ziyi, and left first.
He Dang finally found an opportunity and sat down next to Deng Ziyi with a plate in hand. "Oh my god, Junior Sister, what's going on?"
The scene just now was indeed a bit weird.
Deng Ziyi sighed deeply: "That's what you see."
"Ok?"
"This whole afternoon, I realized one thing."
"What did you say?" "Junior brother is telling the truth. He is really not weak in physics."
"."
At 10 o'clock in the evening, Xu Qingzhou finally returned home, exhausted. Since the afternoon, he had been doing complicated calculations, which were very stressful for his brain.
Song Yao had also returned. She had just finished taking a shower. She tilted her head and let her hair fall to one side, rubbing it with a towel.
Xu Qingzhou looked at the white calves, and his fatigue instantly disappeared. He took the hair dryer and prepared to help Song Yao blow her hair.
"I'll do it myself." Song Yao saw the fatigue on Xu Qingzhou's face, and saw Xu Qingzhou shaking his head, so she sat down on the chair honestly.
Looking from Xu Qingzhou's angle, he could see the fair and delicate neck, the exquisite collarbone, and down there, the feeling of being able to fit in one hand. At the same time, there was a special fragrance in the scent of shampoo.
After about 10 minutes, the "buzzing" sound in the living room disappeared.
After helping Song Yao blow dry her hair, Xu Qingzhou fell back on the sofa to continue resting.
"Are you tired?" Song Yao combed her hair.
"How should I put it?" Xu Qingzhou thought for a moment and said, "In terms of intensity, it's just that. It's mainly because of the commuting. It takes more than an hour to go back and forth."
Especially in the morning, Xu Qingzhou has to squeeze into the subway like many other office workers. Having not seen the morning rush hour for many years, there is only one idiom in his mind: It's so horrible.
"Do I need to run every day in the future?"
"No, I brought all the information back with me. I can finish the work at home. When it's done, or if I encounter any problems in the middle, I can go to the institute."
As he spoke, Xu Qingzhou stood up. After spending a whole day in the laboratory, he always felt the smell of the machines in the laboratory.
Boys usually take a shower quickly and come out in a flash.
Seeing Xu Qingzhou coming out, Song Yao raised the hair dryer in her hand and said, "I'll help you."
Xu Qingzhou did not refuse. He pulled a chair and sat down, enjoying the service of School Beauty Song.
Song Yao took the hair dryer and waved it on Xu Qingzhou's head. His hair was not long and it was even a little prickly to touch, but it felt itchy and quite comfortable.
I originally wanted to do it a few more times, but Xu Qingzhou's hair was very short, so it was blown clean very quickly.
After enjoying the service of School Beauty Song, Xu Qingzhou leaned back on the sofa again, closed his eyes and rested. After taking a shower, he felt completely relaxed.
Song Yao walked over and saw that Er Miao had occupied her throne. She held it in her arms and sat down next to Xu Qingzhou. For some unknown reason, she leaned on the armrest of the sofa, stretched her legs, and put them on Xu Qingzhou's thighs.
"."
Xu Qingzhou suddenly opened his eyes.
Developed it?
On the opposite side, Song Yao turned her eyes away as if nothing had happened and teased the second cat in her arms.
She wouldn't suspect that she has some weird hobbies, right?
Although it was very enjoyable, Xu Qingzhou felt the need to clear his name: "Actually, I don't have any special fetishes."
"You don't like it?" Song Yao pursed her lips and tried to move her foot away.
Xu Qingzhou was quick to catch the two cute feet that were trying to escape and pinched their tender toes. "I mean, these are all very normal hobbies, not weird at all."
