The Moon In My Arms

   Chapter 112 Quantum Entanglement

   In the last class, the professor talked about quantum entanglement.

   It is estimated that no one understands it, and Qi Yue is also half-understood.

   "Hi! Classmate Qi Yue, you're here! Are you alone again?"

When Qi Yue heard the greeting, she raised her head and glanced at the person who came. Qi Shuhang, a student of the Physics Department, was probably the only person in the classroom who understood, and he was also one of the very few who never missed a class like Qi Yue. , After coming and going, the two became familiar with each other.

   Qi Shuhang and his roommate He Ming sat down on the right side of Qi Yue.

   Qi Yue greeted the two of them, and then said helplessly, "Yeah, I wanted to bring my roommate to accompany me, but Amway failed!"

"Haha! It's strange that Amway succeeds! Quantum mechanics is really hard to understand, and girls like you are even rarer..." Qi Shuhang looked at the book Qi Yue opened and asked, "What were you thinking about just now? Are you having trouble again?"

He Ming on the side of    teased, "If you encounter problems, find Shuhang, there are Xueba, so you don't need to be in vain!"

   "Fuck you!" Qi Shuhang bumped He Ming with his shoulder, then touched his nose and looked at Qi Yue, "Why don't you understand?"

   Qi Yue sighed: "I still don't quite understand what the professor said in the last class..."

   "Quantum entanglement? It's actually quite understandable. Suppose a zero-spin neutral pion decays into an electron and a positron. The two decay products move in opposite directions..."

  Qi Shuhang did learn very solidly and started to explain it incessantly, but unfortunately, Qi Yue didn't understand much...

   After all, understanding quantum mechanics is as difficult as learning it.

Probably seeing that Qi Yue didn't understand, Qi Shuhang coughed lightly and pulled the topic aside, "Student Qi, have you ever seen such a statement that two particles are entangled with each other, and they are about to be separated by a long distance. Action will affect the state of the other, so there is a saying that if a person misses you enough, then he can reach your dream..."

  Qi Yue thought for a while and said, "I seem to have seen it, although it's just a conjecture, it's quite a romantic statement..."

   Having said this, Qi Yue inexplicably thought of the dream this morning...

   "Is that so..." Qi Shuhang scratched his head, seeming a little embarrassed, and said hesitantly, "Student Qi, actually I..."

   Before Qi Shuhang finished speaking, the preparation bell rang.

   followed, and there was a steady and neat sound of footsteps at the door of the classroom.

  The peach petals on the branches were blown off by the breeze, fluttering and blowing into the door, and a few fell on the shoulders of the people who came.

  Qi Yue accidentally looked up and saw that the visitor was wearing the familiar white shirt and a simple coat, stepping into the classroom from the spring breeze...

  In the classroom, a few scattered classmates let out the sound of gasping at the same time, and almost everyone woke up from a drowsy state in an instant.

   Qi Shuhang stared at the man at the door in disbelief, "Damn it! Hugh... Hugh?"

  He Ming's eyes widened instantly, "It's really a boss! Why is the boss here? He also took this course?"

Qi Shuhang said speechlessly: "Do you have any common sense! The boss is mainly focused on quantum mechanics in HF, and he has also been a lecturer. How could he come here to listen to elective courses at the entry level of the university at his level? This is a full-level boss. What's the difference between accumulating experience in the novice village? Isn't this a waste of time?"

  He Ming patted his forehead: "By the way, I see, did the boss come to substitute the class?"

   I must be crazy to come up with a quantum mechanical setting! Just looking up information for a few hundred words made me dizzy, and my world view was about to collapse. I originally thought that after I figured it out myself, I would organize and tell you what quantum mechanics is in simple language, so that you can feel more involved. Then I found out, I'm sorry, I'm over the top (┳＿┳), who gave me the courage to write this...
