"I..."

"Actually, the question before Yuxi, I won't... I went out of this way to consult my professor. Liu Yun'er said helplessly: "Your domain is completely different from mine, I don't know what to do at all, so I can only ask others to help." ”

"No, no, no!"

"This is your domain. Dr. Wang said seriously: "I heard Yuxi say that you are an expert in the field of quantum mechanics and have many top papers... And this time we need an expert like you to help us solve a problem in quantum mechanics. ”

Quantum mechanics?

That's fine.

Followed by

Dr. Wang took out a document from his satchel and handed it to Liu Yun'er.

When Liu Yun'er opened this document and read it carefully, she instantly felt a sense of despair... This is a question about quantum information physics, albeit a short formula that is extremely simple, but it would allow all the calculations to be derived from Hardy's theorem.

What is Hardy's theorem?

This is a very, very important study of Bell's non-locality, which is one of the most peculiar theorems in quantum mechanics, and the peculiarity is that three chances P1, P2 and P3 can be constructed, and when all three chances are required to be zero, then according to the classical theory, the fourth chance P4 must be zero.

But...

According to quantum theory, it is possible to find a non-zero probability P4.

Then

Liu Yun'er fell into deep thought, and at the same time... activated the challenge cells in her body, as Liu Yun'er, who has been a talented woman since she was a child, has always been fearless of difficulties, especially in the difficulties that belong to her own field, obviously... Liu Yun'er was on the bar.

"Xiao Yun'er?"

"Can it be solved?" asked Song Yuxi cautiously.

“...”

Liu Yun'er raised her head, looked at Dr. Wang and her best friend in front of her, and said seriously: "Are you in a hurry? If you are not in a hurry, give me a few days... I'm thinking about it because it's a very complex calculation and I need time!"

"No problem!"

"Anyway, we've been stuck for a long time, and it's not a matter if it's a month late. Dr. Wang smiled, "Professor Liu... I'm sorry for you. ”

"Hmm..."

Liu Yun'er is back to the problem, she is thinking about how to solve... In fact, if it is an ordinary Hardy's theorem problem, it does not take too much time at all, and the entire calculation process can be deduced in minutes, but this problem does not follow the usual path.

Also...

If you go off the beaten path, you won't find yourself.

"Little Yun'er..."

"Then we'll leave first, so we won't bother you. Song Yuxi saw that her good sister was devoting herself to that question, and said softly.

"Oh..."

Liu Yun'er nodded and said indifferently: "Then I won't send it..."

"No, no, no!"

"You're busy," Dr. Wang smiled, "Professor Liu, let's go." ”

"Hmm..."

afterwards

Liu Yun'er was left alone in the office, and a desperately complicated calculation process.

After an hour and a half of hard work,

Sure enough, it lived up to expectations,

Liu Yun'er still hasn't solved it, but she hasn't given up... As Lin Fan said, there are two kinds of geniuses in this world, one is an ordinary genius who solves problems that ordinary people can't solve, and the other is a peerless genius who solves problems that ordinary geniuses can't solve, and Liu Yun'er thinks that she is the latter.

So

This problem must be solved!

At this moment,

A face appeared in Liu Yun'er's mind, speaking from her heart... This face is a little handsome, but there is a little cheapness in the handsomeness, and at the same time it reveals a faint scumbag atmosphere.

That's right

She thought of the scum forest, if the scum forest faced this problem, could he solve it in the first place?

"Humph!"

"I don't want him to help!" Liu Yun'er said to herself with a stubborn face: "It seems that I am very incompetent... I'm a professor of basic physics in quantum mechanics majoring in theoretical physics at the Physics Branch of Shanghai University!"

At this moment,

Every student in Liu Yun'er's body is refusing to help, all in all... To hell with the scumbags!

...

Afternoon

Lin Fan finally stayed up until the end of work, and as the second hand arrived at the reserved location, Lin Fan was nowhere to be seen, and he had to rush home to play games and put what he lost yesterday... Take it all back.

When I arrived at the place agreed with Liu Yun'er, the white Audi had not yet arrived, and Lin Fan was standing in the cold wind... Drinking the northwest wind.

soon

The white Audi appeared, stopped beside Lin Fan, and then he calmly opened the car door, fastened his seat belt, and said with a smile: "Alas... Can you be a little faster today?"

"Don't you usually let me be fast?" Liu Yun'er said indifferently: "Why hurry up today?"

"Rush home and play the dungeon!"

"Two small copies were updated just today. Lin Fan said seriously: "I'm going to brush up my reputation." ”

Hearing Lin Fan's words,

Liu Yun'er was so angry that she gritted her teeth, and thought that what happened... The result is a game, is it really that important to him?

"Can't do it!" Liu Yun'er said expressionlessly: "Half an hour at the earliest, do you like to sit or not." ”

In fact

This is a normal time, because it is during the rush hour after work, even if Liu Yuner has the skills of a racer, she will be stuck in traffic.

But... Lin Fan wanted to tease this refrigerator and make her low-key and dull life more interesting.

"Shut your mouth for me!"

"I'm going to say a time now... You'll have to get me out there in this time. Lin Fan said solemnly: "One minute!"

In a flash

Liu Yun'er braked, and Lin Fan almost didn't die in the passenger seat.

"You take the bus for me!" Liu Yun'er said with a dark face.

"Huh?"

"Oops... Look at it, it's funny!" Lin Fan said with a smile: "You are beautiful, and you are so smart, the only drawback is that you don't have a humor cell, I'm not cultivating your humor cell..."

"Cultivate with you?" Liu Yun'er said angrily: "From now on... When I'm driving, you're forbidden to speak!"

...

Dinner time,

Still in room 304,

Lin Fan was playing the game while eating the deluxe version of abalone sauce rice that Liu Yun'er treated, his face was full of happiness, joking... One hundred and twenty dollars a bowl.

After eating,

threw the lunch box to the side, then took out a tissue and wiped his mouth, then glanced back at Liu Yun'er, only to find that... The woman was eating, holding a pen and not knowing what was written on the paper.

"What are you doing?" Lin Fan asked curiously.

Suddenly

Liu Yun'er hurriedly pressed the white paper on the table with her body, looked at Lin Fan vigilantly, and said, "Don't look at it!"

Then

Lin Fan froze in place, he saw something he shouldn't have seen.

At this moment,

Liu Yun'er reacted and lowered her head to look.

In a flash...

The atmosphere became eerie.
