Scholar’s Starry Sea

In the next few days, Wu Bin seems to become an "inherent attraction in Pei Jiamin's house."

He always sits on the sofa in the living room It was a whole day, in addition to eating and greeting Pei Zhenhua and the others who had just returned home, it was a statue in a sense.

Gu Jiaqi once crept up to Wu Bin to take a look, but was quickly shaken back by the densely packed English and a large number of unknown symbols on the screen.

"Wu Bin, ready to eat." Lu Miaomei, who had just brought the soup to the table, shouted, moved towards Wu Bin.

"Aunt, you have to eat first, I still have some calculations to do." Wu Bin stopped the pen in his hand and looked towards Lu Miaomei with some regrets.

"Okay, then I will put a few pieces of meat in the steamer to help you heat it up."

"Thank you Aunt." Wu Bin nodded, continue looking towards the computer.

……

"Sister Minmin, pass me the napkin." Gu Jiaqi, who had just eaten a piece of oily meat, said to Pei Jiamin, but her voice was as small as Pei. Jiamin couldn't hear clearly.

"What?" Pei Jiamin asked.

"Napkin~napkin~paper~" Gu Jiaqi continued to speak in a very small voice while pointing to the paper box at the corner of the table.

"Oh yo..." Pei Jiamin gave her a helpless look after hearing it, and took out two napkins and handed it to her, "Would you like to be so ostentatious?"

"I'm afraid it will affect Wu Bin's research and become a sinner in human history." Gu Jiaqi's voice remained low.

Lv Miaomei couldn’t help poking Gu Jiaqi’s forehead after listening, "Ghost Spirit Essence, you know that people are crazy, talk hard."

"I mean the truth..." Gu Jiaqi poked the rice in the bowl with chopsticks aggrievedly, "What he saw made me suspect that I never went to school at all."

"You can understand it when you go to university. "Pei Zhenhua on the side said with a smile.

"Really?" After Gu Jiaqi finished looking towards Pei Jiamin, "Sister, can you understand?"

Naturally, Pei Jiamin didn't want to answer her, but just showed her one. An awkward and polite smile.

Gu Jiaqi, who snickered twice, glanced at Wu Bin again, and found that his expression was as focused as before, as if separated from the world on their side.

'Probably this is Bookworm...'

At this time, Wu Bin, who was checking the formula, suddenly felt a vibration in his thigh, so he took out the phone and looked at the caller ID and it was Li Yan Then I pressed the call button.

"What happened? "

"There is a lecture given by Professor Pan on Sunday afternoon. Would you like to listen to it?" "

"Professor Pan? Which Pan...hmm! ? Could it be Professor Pan Jianwei! ? "

Wu Bin’s sudden excitement shocked the people at the table next door and looked towards him.

Moved towards Pei Jiamin, they showed an apologetic expression After smiling, Wu Bin continued to listen to Li Yan from the obedient side.

"Yes, there is a Mozi Sand Dragon on Sunday, so you can sign up. "

"What is the lecture about? "

"Public welfare science, not too deep, but I think it should be very interesting. "

"go go go, I must go, can I still register now!" ? "

"What's your hurry? This is a popular science lecture, Old Brother, and it's not a concert. It's hard to get a ticket?" Alright, I have already signed up, I will pick you up on Sunday? "

"Don't bother, I just go by myself. "

"You're welcome, anyway, I'll see you on Sunday, bye~"

Hang up, Wu Bin said in his heart that this guy is really strong, and he continued to prepare Do his calculations.

"Wu Bin, who is Professor Pan Jianwei? It's rare to see you so excited. "At this time, Gu Jiaqi, who couldn't hold back his curiosity, came over and asked.

Speaking of Pan Jianwei, this is also a top domestic "controversial" scientist.

Soon after China, Fang Zhouzi pushed him into the public eye with an article "Pan Jianwei is a liar" Domain, Quantum information.

What is Quantum in the first place? Simply put, it is "the smallest unit of discrete change". , Four, but you are impossible up to half a step. This is the feeling of separation, and Quantum plays the role of step in the micro world.

How to accurately describe the Physics theory of the micro world, It is Quantum mechanics.

What contribution has Quantum mechanics made to mankind at present?

Very much.

Because the properties of macroscopic matter are determined by the microstructure .

For example, it’s the same piece of glass, some of which are broken when dropped, but some are bulletproof. This is the change that changes its microstructure.

In In 1900, when Planck was studying the problem of "black body radiation", he discovered for the first time that a certain Physics quantity must be regarded as a discrete change. In black body radiation, this Physics quantity is based on the energy carried by the radiation.

Einstein, Bohr, De Broglie and the others have all put forward many important concepts, and gradually formed a huge application range of Quantum mechanics.

During the period, there was a lot of food. The truth of the misunderstanding of the masses is that Einstein was actually awarded the Nobel Physics Prize for the Quantum Theory of Light when explaining the photoelectric effect, rather than the well-known theory of relativity.

After that, Heisenberg And Schrödinger further strengthened Quantum mechanics. These two people gave a set of theories that can accurately describe any microscopic phenomenon in the Mathematics language of matrices, and the Mathematics language of differential equations gave another set of theories, and It quickly proved that the two theories of these two people are equivalent.

Since then, human beings have broken into this mysterious micro world and created a lot of things that can be called miracles. .

Because Quantum mechanics explained to humans a series of various Physics phenomena that can be seen in daily life, such as electrical conductivity, thermal conductivity, hardness, superconductivity, and supercurrent, so the later technological achievements of modern society, Almost all have the same Quantum mechanics relation.

To get a preliminary understanding of what Quantum information is being studied by Professor Pan Jianwei, you have to know the framework of Quantum mechanics, among which is included superposition, measurement and entanglement.

The core concept is the transformation of Quantum state.

These concepts are all full of mysterious to humans.

First of all, bit is the basic concept of computer science. It refers to a system with only two possible states, namely 0 and 1.

It's like flipping a coin, and the result is either heads or tails.

At this time, the first mysterious concept in Quantum mechanics, the "superposition principle" has appeared.

The concept it expresses is that if two states are allowed by a system, then their arbitrary linear superposition is also a state allowed by the system.

The famous "Schrödinger's Cat" experiment refers to this phenomenon.

It means that the cat in the box is in a "superimposed" state of death and alive. You must wait to open the box and take a look at the cat to determine its life or death.

This is what Quantum mechanics tells us, unless you make observations, everything is uncertain.
