Chapter 270 Science Can Stand Question

However, Einstein refused to accept the theoretical results created by Schrödinger. He believed that quantum mechanics is just a reasonable description of the behavior of atoms and subatoms. It is a phenomenological theory, and it is by no means the ultimate truth.

For this he also said a famous saying.

"That's why God doesn't play dice."

He does not recognize Schrödinger's cat eigenstate theory, and believes that there must be an internal mechanism that constitutes the true nature of things, and spent several years trying to design an experiment to test whether this internal reality is indeed working. It is a pity that he died before completing this design.

Of course, this is the love and death between quantum physics and classical physics. So far, they have not fought for a victory, so it is good to pay attention to the conclusion of quantum mechanics first.

Generally speaking, in the state of quantum superposition, bits become qubits, so it is no longer only able to obtain 0 and 1, but can be in more states.

It is precisely because a qubit potentially contains a much larger amount of information than a single bit that many scientists believe that the computing power of quantum computers will far exceed that of classical computers.

But the reason why it is described as "potentially" is because this is just a guess. If you really want to bring out its characteristics, you need a smart enough experimental design.

The next mysterious concept, quantum entanglement, provides the most important prerequisite for quantum communication.

Simply put, it is two temporarily coupled particles. Even if they are no longer coupled later, they still maintain a relationship with each other.

For example, two electrons moving in opposite directions but at the same speed, one goes to the side of the sun, and the other goes to the side of Mars. Even though they are so far away, they still maintain their correlation.

What Professor Pan Jianwei is researching is quantum communication derived from quantum entanglement.

Since ancient times, generals who are good at fighting have understood the importance of intelligence, and how to encrypt intelligence has become one of the most important military affairs for every army.

The world's first computer invented by Turing was used to violently crack the Enigma cipher machine of the German army, and in the end it did cost the German army a heavy price.

This shows how important information encryption is.

The research direction of Professor Pan Jianwei is to use quantum principles to encrypt information.

The first realization of quantum teleportation was in 1997. At that time, Professor Pan Jianwei was studying for a doctoral degree under Professor Salinger of the University of Innsbruck in Austria. An article called "Experimental quantum teleportation".

Later, this article was selected into "Nature"'s "21 Classic Papers in Physics over the Century."

Its parallel papers include Roentgen's discovery of X-rays, Einstein's theory of relativity, and Watson and Crick's discovery of the DNA double helix structure, among others.

It is enough to show the importance attached to this article by the scientific research community.

After returning to China, Professor Pan Jianwei also wanted to do something drastic. When applying for funds, he directly used the unit of [-] million.

And this huge consumption of funds has always been the target of Professor Pan Jianwei's attack.

"Before the principle is clear, you start to talk about practical application?"

"Wow, I smell water turning to oil."

"Starting to draw pancakes again?"

"It's obvious that the two parties randomly and randomly discussed the secret key. They have to use some kind of quantum entanglement to appear superior."

……

In fact, it has always been a very reasonable thing to question science, because the reason why science is more reliable than metaphysics is because it can stand doubt!
However, the complexity of modern science is not something that one person just jumps out and shouts one day.

"I found out! It turns out that the fire can be extinguished with a haystack!"

At this time, a group of people who used water to extinguish fires and use haystacks to make fires every day laughed immediately after hearing this, shouting, "Where are you idiots? Why don't you just stay cool?"

But the man smiled slightly after hearing this, and calmly lit a fire, then picked up a bundle of grass and quickly extinguished it, and finally turned around and left in a cool manner, leaving a group of stunned people behind.

But explain quantum mechanics to the public?Seriously... my friend, there are times when even a four year undergraduate in quantum mechanics can't say he's even scratched the surface.

If you want to question Professor Pan Jianwei’s article, tear him up, no problem, write an article to refute him and publish it in a journal of the same strength, then even if you tear up the other party’s underwear, people in the scientific research community will only applaud you Applause, and let you tear harder!
But if you write an article that doesn’t even have a single Greek letter and post it on Weibo, it’s such a complicated issue. This is called taking the rhythm of the people. Thank you.

Today, Professor Pan Jianwei is already an academician of the University of Science and Technology, and has honors such as "Nature" Top Ten Scientific Figures of the Year, "Time Magazine" and "World's Most Influential Figures".

But the voices of doubt have not stopped.

"A foreigner's magazine says he is a character, and the Chinese have an orgasm?"

"You can get this kind of magazine with money, right?"

"I'm afraid it wasn't sent by foreigners to cheat funds in China."

How should I put it, time will tell whether everything is right or wrong.

However, no matter whether you are bragging or scolding, this kind of controversy has made Professor Pan Jianwei, or quantum communication, more and more influential, so big that even the 1024 forum can see related posts.

The next era may not be the encrypted transmission of pornography...

After thinking for a moment, Wu Bin looked at Gu Jiaqi and replied:

"He is a master in quantum physics and one of the pioneers in the field of quantum information experimental research." Wu Bin looked up and replied.

Although Gu Jiaqi wanted to ask what the quantum information experiment was, a firm voice suddenly appeared in her mind.

"No, you don't want to!"

And Gu Jiaqi obeyed the voice decisively, nodded and said, "Wow, that's amazing." Then she continued to eat.

And Wu Bin also shook his head with a smile and continued to check his calculations.

As for whether quantum communication is "sci-fi metaphysics", he doesn't want to participate in unnecessary debates. He just wants to find out one day with his own ability!
PS: I think my writing style has never changed, just like what I said in my testimonial, what I want to write is a master of life, wandering between daily life, scientific research, and popular science.

And you can still talk about water after catching up to the latest chapter... To be honest, isn't this book just updated slowly and without content for you...I'm afraid that you can catch up to the latest chapter. want?
To this I just want to say "No date!"

PS2: If you fail the update event on the first day, you will be directly disqualified... Damn it, my mentality is broken.
