Chapter 270 Science Can Withstand Questioning
However, Einstein refused to accept the results of this theory founded by Schrödinger. He believed that quantum mechanics is only a reasonable description of the behavior of atoms and subatomic atoms, a phenomenological theory, and it is by no means the ultimate truth.
He also said a famous saying about this.
"That's God doesn't play dice."
He did not admit Schrödinger's theory of non-eigenstates of cats, believing 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 was indeed at work. Unfortunately, he died before completing this design.
Of course, this is a love-and-death battle between quantum physics and classical physics. So far, they have not come to a winner, so just focus on the conclusions of quantum mechanics first.
In general, in the state of quantum superposition, bits become qubits, then they can no longer only 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 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 runs to the side of the sun, and the other runs to the side of Mars. Even though they are so far away, they still maintain their correlation.
What Professor Pan Jianwei studies 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 matters for every army.
The world's first computer invented by Turing was used to violently crack the German Enigma cipher machine, and in the end it did cost the German army a heavy price.
This shows how important information encryption is.
Professor Pan Jianwei’s research direction 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 at the University of Innsbruck, Austria. As the second author, Professor Pan Jianwei and his supervisor published a paper in "nature". An article called "Experimental quantum teleportation".
Later, this article was selected into "Nature"'s "21 Classic Papers in Physics over the Century."
Papers juxtaposed with it include Roentgen's discovery of X-rays, Einstein's establishment of the theory of relativity, Watson and Crick's discovery of the double helix structure of DNA, and so on.
It is enough to show the importance that the scientific research community attaches to this article.
After returning to China, Professor Pan Jianwei also wanted to do something drastic and drastic, so when applying for funds, he directly used the unit of 100 million.
This huge expenditure of funds has always been the target of attacks on Professor Pan Jianwei.
"You start talking about practical applications before the principle is clear?"
"Wow, I smell water turning to oil."
"Starting drawing pie 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, questioning science has always been a very reasonable thing, because the reason why science is more reliable than metaphysics is because it can withstand questioning!
However, the complexity of modern science is not something that one person just jumps out and shouts one day.
"I discovered it! It turns out that you can put out fires with haystacks!"
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 after hearing this, the man smiled slightly, lit a fire very calmly, then picked up a bundle of grass and quickly swatted it out, and finally turned around and left in a cool manner, leaving a group of stunned people behind.
But explain quantum mechanics to the public? To be honest...friends, sometimes even undergraduates who have studied quantum mechanics for four years dare not say that they understand the basics.
If you want to question Professor Pan Jianwei's article, if you want to tear him apart, no problem. Write an article to refute him and publish it in a journal of equal strength. In this case, even if you tear the other person's underwear, people in the scientific research community will only applaud you. Applause, and let you tear harder!
But if you write an article without even a single Greek letter and post it on Weibo to tear apart such a complex issue, this is called leading the people to the rhythm of thank you.
Today, Professor Pan Jianwei is an academician of HKUST and holds honors such as being one of the top ten scientific figures of the year by Nature and the most influential person in the world by Time Magazine.
But the voices of doubt have not stopped.
"Foreign magazines say he is a figure, and Chinese people are excited?"
"You can get into this kind of magazine with money, right?"
"I'm afraid they were not sent to China by foreigners to defraud funds."
How to say, time will prove everything is right or wrong.
However, whether it is boasted or criticized, this kind of controversy has made Professor Pan Jianwei, or quantum communication, more and more influential, so much so that even the 1024 forum can see related posts.
I’m afraid the next era won’t be about encrypted transmission of pornographic films…
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 very firm voice suddenly appeared in her head.
"No, you don't!"
Gu Jiaqi also decisively followed the voice, nodded and said, "Wow, that's amazing." Then she continued to eat.
Wu Bin also smiled and shook his head and continued 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 introduction, what I want to write is a scholar who lives in the flow of life, walking between daily life and scientific research and popular science.
And you can still catch up on the latest chapter... To be honest, for you, isn't this book just slow to update and has no content... I'm afraid it's not a disservice to me that you can catch up on the latest chapter. Thoughts?
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.
