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. He nodded slightly and was surprised. He just said that Xu Qingzhou might have to get used to this place. The work, the result.
Nowadays, the young people are really fierce.
Before he finished his emotion, his attention quickly returned to the blackboard, because Xu Qingzhou briefly wrote down the idea of Hilbert space expansion.
“In this way, we can use the inner product operation of Hilbert space equipment. The norm derived from the inner product defines the length or size of the vector.”
Professor Zhong He frowned slightly and said: "The fragility of quantum states, any small disturbance may lead to the loss of quantum coherence and the loss of quantum information."
"Yes, I have also considered this."
Xu Qingzhou nodded, picked up a marker and drew on the blackboard.
“First, we can use the error suppression method to perform active feedback control to reduce the interference of environmental noise and equipment errors on the quantum state. Second, we can construct redundant information in the Hilbert space to detect and Correcting qubit errors."
"."
Beside the two of them, Deng Ziyi has now calmed down a little, or in other words, has started to show off, and is completely unable to keep up with the thoughts of Professor Zhong and Xu Qingzhou.
She was a little hurt. She was still saying that I had the advantage in the morning. The reversal came too fast. Without any preparation, the blow just appeared in front of her.
There are indeed such perverted people in the world. Not to mention that mathematics is terrible, physics is also ridiculously strong. Take a look, you can easily pick up the formulas in the quantum field.
Xu Qingzhou and Zhong The professor discussed for half an hour and finalized the basic framework before starting the formal calculation.
"Okay, your idea is very good! I was originally worried that you wouldn't be able to keep up, but it seems I was overly worried."
Professor Zhong looked at Xu Qingzhou in amazement, and at the same time, With some excitement in his eyes, he said: "The whole part of rewriting the Schrödinger equation into the form of a time evolution operator will be left to you."
"No problem." Xu Qingzhou nodded with a smile.
"Let's get started. If there are any problems during the period, we will discuss it." Professor Zhong directly regarded Xu Qingzhou as someone of the same level.
The two immediately sat down and began to calculate.
Deng Ziyi sighed secretly and poured a glass of water for the two bosses before starting to sort out the data.
The afternoon passed by 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.” Professor Zhong regretted.
“If you consider using different degrees of freedom of photons, such as orbital angular momentum mode, you can achieve the preparation of higher-dimensional quantum states.”
Xu Qingzhou took a few mouthfuls of food, chewed it, and then Said: "You can also use the state mapping method between the two degrees of freedom of polarization and orbital angular momentum to improve the accuracy and stability of the preparation."
"This method, well, may be very promising."
Deng Ziyi happily drank tomato omelette soup, Ababa, Ababa, what matters is quantum, dry rice is the most important thing!
But He Dang next door is different, his expression is quite complicated.
Sometimes it is about constructing redundant information, and now it is about the preparation of quantum states. You said that it would be okay if Professor Zhong outputs it unilaterally. Why is Xu Qingzhou vaguely at odds with Professor Zhong.
Sitting and discussing the truth?
Xu Qingzhou and Professor Zhong ate relatively quickly, said something to Deng Ziyi, and left first.
He Dang finally found the opportunity and sat down next to Deng Ziyi with a dinner plate, "I'll go, junior sister, what's going on?"
The scene just now was really weird.
Deng Ziyi sighed deeply: "This is what you see."
"Huh?"
"This whole afternoon, I realized something."< br>
"What are you talking about?" "Junior brother is actually telling the truth. He is really not weak in physics."
"."
10 p.m. , Xu Qingzhou finally went home dragging his empty body. Since the afternoon, he has been basically doing complex calculations, which is nerve-wracking.
Song Yao has also come back. She has just finished taking a shower. She tilts her head to let her hair fall to one side and is rubbing it with a towel.
Xu Qingzhou looked at his fair calves, his fatigue was reduced by half in an instant, and he took a 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, saw Xu Qingzhou shook his head and sat down on the chair honestly.
Looking from Xu Qingzhou's point of view, the white and delicate neck, the delicate collarbone, and the feeling of a firm hand downwards, at the same time, there is a special fragrance in the fragrance of the shampoo.
About 10 minutes, the "buzzing" sound in the living room disappeared.
After helping Song Yao blow dry her hair, Xu Qingzhou fell on the sofa and continued to rest.
“Very tired?” Song Yao combed her hair.
"How should I put it?" Xu Qingzhou thought for a while and said: "In terms of intensity, it is actually just that. The main reason is that I am tired from commuting. It takes more than an hour to go back and forth."
Especially in the morning, Having to squeeze into the subway like the majority of people in society, Xu Qingzhou, who has not seen the morning rush hour in many years, only has one idiom in his mind: It's so scary.
“Will I need to run every day in the future?”
"No, I have brought all the information back. I can finish the work at home. When it is finished, or if there are problems in the process, I will go to the research institute."
As he said that, Xu Qingzhou stood up and said After spending a day in the laboratory, I always felt that my body smelled like the machines in the laboratory.
Boys usually take a shower quickly, just pass through a stream of water and come out.
Seeing Xu Qingzhou come out, Song Yao raised the hair dryer in her hand: "I'll help you."
Xu Qingzhou didn't refuse, pulled up a chair and sat down, enjoying the service of Song School Belle.
Song Yao took the hair dryer and shook it on Xu Qingzhou's head. His hair was not long and even pricked his hands when he touched it, but it was itchy and quite comfortable.
I originally wanted to do more moldings, but Xu Qingzhou’s hair was very short and it was done quickly.
After enjoying the service of the school belle of Song Dynasty, Xu Qingzhou leaned on the sofa again, closed his eyes and rested. After taking a bath, he felt completely comfortable.
Song Yao came over and saw Ermiao occupying her throne. She held it in her arms and sat down next to Xu Qingzhou. By some strange combination of circumstances, she leaned on the armrest of the sofa, stretched her legs and rested on it. On Xu Qingzhou's thigh.
“.”
Xu Qingzhou opened his eyes suddenly.
Developed?
Across the way, Song Yao looked away as if nothing had happened, teasing Er Meow in her arms.
Won’t she suspect that she has some weird hobbies?
Although it was very satisfying, Xu Qingzhou felt the need to clear his name: "Actually, I don't have any special hobbies."
"You don't like it?" Song Yao pursed her lips and asked Move your feet away.
Xu Qingzhou had quick eyes and quick hands. He grabbed two cute paws that were trying to escape and pinched the delicate toes. "I mean, these are normal hobbies, not surprising."
