Chapter 226: Cultivated?

2 minutes passed.

"Hmm, this method of yours is very good; it corrects the problem of uneven numerical calculation." Professor Zhong stared at the blackboard, thinking for a long time, nodding slightly, feeling incredibly surprised. Just a moment ago, he had said Xu Qingzhou would probably need to adapt to the work here, but now... the young people today are truly fierce.

Before he could finish his exclamation, his attention quickly returned to the blackboard because Xu Qingzhou had now simply written down his idea for expanding the Hilbert space.

"This way, we can use the inner product operation equipped in the Hilbert space, and the norm derived from the inner product defines the length or magnitude of the vector."

Professor Zhong frowned slightly and said: "But the fragility of quantum states means any tiny disturbance could lead to the loss of quantum coherence and the loss of quantum information."

"Correct, I have also considered that."

Xu Qingzhou nodded and picked up a marker to doodle on the blackboard.

"First, we can use error suppression methods to perform active feedback control, reducing the interference of environmental noise and equipment errors on quantum states. Second, we can construct redundant information in the Hilbert space to detect and correct qubit errors..."

One moment it was constructing redundant information, the next it was mentioning the preparation of quantum states. You could say it was fine if Professor Zhong was outputting unilaterally, but why did it feel like Xu Qingzhou was vaguely on track to go toe-to-toe with Professor Zhong?

Deng Ziyi was happily drinking tomato and egg soup. *Aba aba*, what quantum or not quantum, eating is the most important thing!

Cultivated? Opposite, Song Yao looked away as if nothing happened, teasing Er Miao in her arms.

Seeing Xu Qingzhou come out, Song Yao raised the hair dryer in her hand: "I'll help you."

Deng Ziyi sighed deeply: "It's just as you see."

Xu Qingzhou didn't refuse; he pulled up a chair and sat down, enjoying the service of the school beauty.

"If we consider utilizing the different degrees of freedom of photons, such as orbital angular momentum modes, we can achieve the preparation of higher-dimensional quantum states."

Deng Ziyi sighed secretly, and before starting to organize the data, she poured a glass of water for the two big shots.

"No problem," Xu Qingzhou nodded with a smile.

Especially in the morning, having to squeeze onto the subway like the vast number of corporate slaves, Xu Qingzhou, who hadn't experienced the morning rush hour for many years, had only one idiom in his heart: Terrifying.

"."

Song Yao held the hair dryer, *woo woo woo*, helping to shake it over Xu Qingzhou's head. His hair wasn't long, and it even felt a bit prickly to the touch, but it was itchy and quite comfortable.

Boys usually wash their hair relatively quickly, just a rinse and they're out.

Song Yao walked over, saw Er Miao occupying her throne, held it in her arms, and sat next to Xu Qingzhou. By some strange twist of fate, she leaned against the sofa armrest, stretched her feet, and rested them on Xu Qingzhou's thigh.

The scene just now was truly a bit bizarre.

"Very tired?" Song Yao combed his hair.

"."

Xu Qingzhou looked at the fair calves, his fatigue instantly reduced by more than half, and he picked up the hair dryer, ready to help Song Yao dry her hair.

Professor Zhong looked at Xu Qingzhou in amazement, and at the same time, there was some excitement in his eyes, saying: "Then the part about rewriting the Schrödinger equation into the form of a time-evolution operator will be entirely handed over to you."

He Dang finally found an opportunity, carried his tray, and sat next to Deng Ziyi, "Damn, Junior Sister, what's the situation?"

"Good, your idea is very good! I was originally worried that you wouldn't be able to keep up with the rhythm; it seems I was overthinking it."

"."

!.

"I'll do it myself." Song Yao saw the fatigue on Xu Qingzhou's face, and seeing Xu Qingzhou shake his head, she sat honestly in the chair. As she spoke, Xu Qingzhou stood up. After staying in the laboratory for a day, he always felt like he was covered in the smell of the machines from the lab.

"How should I put it." Xu Qingzhou thought for a moment and said: "As for the intensity, it's actually just like that; it's mainly the commute that's tiring, it's over an hour back and forth."

After helping Song Yao dry her hair, Xu Qingzhou collapsed on the sofa to continue resting.

"There is a lack of mature technical means for the preparation, measurement, and verification of high-dimensional quantum states," Professor Zhong said with some regret.

Beside the two, Deng Ziyi had recovered a bit, or rather, she had given up, completely unable to keep up with Professor Zhong and Xu Qingzhou's train of thought.

Song Yao had also returned. Having just finished showering, she tilted her head, letting her hair fall to one side, and was rubbing it with a towel.

"No need, I brought all the materials back. I can finish the work at home, and when it's done, or if I encounter problems in the middle, I'll go to the research institute."

He originally wanted to stroke it a few more times, but Xu Qingzhou's hair was very short, and it was dried quickly.

"Then let's start. If there are any problems during the process, we'll discuss them," Professor Zhong directly treated Xu Qingzhou as someone of the same level.

At 10 PM, Xu Qingzhou finally dragged his hollowed-out body home. Since the afternoon, he had basically been doing complex calculations, which was brain-draining.

The afternoon passed amidst complex equations on sheets of draft paper.

From Xu Qingzhou's angle, looking over, there was a fair and delicate neck, exquisite collarbones, and further down... a feeling of being able to be held in one hand. At the same time, the fresh scent of shampoo was mixed with a special faint fragrance.

Xu Qingzhou opened his eyes abruptly.

"This method... hmm, it might be very promising."

Discussing the Dao while sitting? Xu Qingzhou and Professor Zhong ate relatively quickly, told Deng Ziyi, and left first.

The two sat down immediately and began to calculate.

"Hmm?"

Xu Qingzhou shoveled a few mouthfuls of food, chewed, and then said: "We can also use the state mapping method between polarization and orbital angular momentum dual degrees of freedom to improve the precision and stability of preparation."

After enjoying the school beauty's service, Xu Qingzhou leaned on the sofa again, closed his eyes to rest. After a shower, he felt completely comfortable.

And He Dang next to her was different; his expression was quite complex.

About 10 minutes later, the "buzzing" sound in the living room disappeared.

There really are such perverted people in the world. Not to mention his math is terrifying, his physics is also ridiculously strong. Look, the formulas in the quantum field are just at his fingertips... Xu Qingzhou and Professor Zhong discussed for half an hour, finalized the basic framework, and then started formal calculations.

She was a bit hurt. Just in the morning, she was still saying the advantage was with her, but the reversal came too quickly, without any preparation, and the blow appeared before her just like that.

"Do I need to run every day?"

"This whole afternoon, I realized one thing."

"What thing?" "What Junior Brother said was actually the truth; his physics is really not weak."

She wouldn't suspect he had some strange hobbies, would she? Although it felt great, Xu Qingzhou felt it necessary to clear his name: "Actually, I don't have any special fetishes."

"You don't like it?" Song Yao pursed her lips, wanting to move her feet away.

Xu Qingzhou was quick-witted, grabbed the two cute feet that wanted to escape, and squeezed the delicate toes, "I mean, these are all very normal hobbies, not strange at all."
