First, a few words from the author:

No, it should be the reader's words.

Book friends who read the author carefully know that I am an old reader who has read books for many years.

Looking back at the opening of the book, it has been a year, and it is worth more than a million words, as an old reader, I feel ashamed of myself!

I have alliance leaders, quite a few, but they are the most bitter alliance leaders in history, no more, no thanks!

I have a book friend, lied to me that there was an idle computer, and I ended up buying a flower for a notebook at a higher price, and I didn't add more, and I didn't thank you.

I have a moderator, Brother Xing, who mailed me two boxes of ham, without adding more, without thanks.

I'm so ashamed!

.......

Speaking of updates, after the operation, my head was confused, this is not the reason for the slow update, and I don't ask for leave, because if I say too much, it will sell badly, I don't want to do this, because I'm very good.

I'm stuck in a strange circle now, it's too much pursuit of reasonableness, but the progress of the article makes me very unfamiliar, because I haven't experienced that kind of high-end environment, and I am very entangled in what is reasonable.

Xiao Baiwen can't get mixed up at the starting point, the pursuit of rationality is not a high-end pursuit, in the final analysis, it is for economic benefits, but the current situation is that the more the pursuit, the slower, the more uneconomical, the strange circle......

Still confused.

Above.

..........

During the recuperation period, in addition to reading physical books, I also reviewed the celebration of more than one year.

Great god-level works, don't comment, in addition to the intrigues and tricks imposed, I didn't expect the cutest favorite Uncle Wuzhu to be.......

Robot.

So, what kind of book is that?

Alternate History, Fantasy, Horror, Science Fiction?

SO......

Popular science begins.

First of all, it is stated that the follow-up text is written and recreated silently, without looking at any information, so it seems to be a popular text that is not completely in line with science, but a non-985, 211 undergraduate, who has not been engaged in this major after graduation, and chatters with the highest junior high school physics knowledge.

Don't be surprised if you see a familiar text, because I've also seen it, and if you haven't read it, or even if you've read it with a confused face, don't panic, because I don't understand either.

Even in the lifetime of the greatest scientist, Albert Einstein, did not figure it out!

For a hundred years, in order to understand this thing, science, philosophy, and even idealism have become popular, and it is precisely because of these people that this thing has developed to this day.......

So, the body begins:

It all started with one of the most famous cats of all time.

That's right, this single chapter is bold....... ...... of quantum mechanics

Lace News.

..........

At the climax, I came up with the first equation of quantum mechanics, and after the incident, my wife was responsible for taking care of the child I had with my friend's wife, and she fell in love with my friend, and I fell in love with my friend's wife's best friend.

Don't get me wrong, I'm not in the entertainment industry, I'm Erwin Schrödinger called the beast, please call me Mr. Xue.

The only regret of my seventy years of life is why my cat is more famous than me?"

The non-existent cat is put in the box, and there is a radioactive atom, if the atom decays, excites the ray, touches the switch, activates the hammer, the hammer falls, breaks the poison bottle, and the cat dies.

The life or death of a cat depends on whether the atom fission, as long as we do not open the box, we cannot know whether the cat is dead or alive, and whether the nucleus fission, and when it fission, is a random event that can never be predicted.

...........

Confused?

Boring not?

What's the matter with us if the cat doesn't die?

You're full enough to get a cat out, and then the incident?

However, Professor Xue is full of eating women, but making cats is not to support it, but to scare a person........

......

"I love physics, I love football.

When I play football, I'm not a star, I'm not a top student, I'm just a genius.

He graduated with a doctorate at the age of 26, became a professor at the age of 28, and won the Nobel Prize at the age of 37, a year before Einstein.

I'm a winner in life, I'm Nils Pol, and I'm a spokesperson for quantum mechanics!"

.........

Before talking about Bohr, we need to think about a very common question with the knowledge of junior high school physics:

Is light a grain or a wave?

More than 100 years ago, in order to understand this problem, scientists made a seemingly simple experiment - double-slit interference, and the result was a collective 'fine separation'!

Double-slit, two slits in the plank, through which photons pass like machine-gun bullets and hit the screen.

If it is two bars, the light is pure particles.

If it is a pure wave, light is a wave.

If it is a hybrid hybrid, the light is a mixture of the two.

There is no fourth possibility.

However, the results of the experiment were as terrifying as Uncle Gotake being a robot, and the fourth scenario occurred......

For the first experiment, light is a wave.

In the second test, light is a wave.

When people breathe a sigh of relief, something frightening happens.

In the third experiment, scientists put a camera, and the result was: light, is particles.

The fourth test, remove the camera, light, is the wave!

........

When an athlete shoots on the football field, whether the ball goes in or not depends on whether the athlete is Messi Ronaldo, the weather at that time, the goalkeeper's play, the hustle and bustle of the fans, and the fairness of the referee.

It's common sense.

But when someone tells you one day that whether you score or not depends on whether you watch TV or not.......

Shabi, right?

It was a moment of schizophrenia for scientists around the globe at that time.

So, Bohr came into play, and what he considered the three basic principles of quantum mechanics came into play:

Superposition principle: Before you watch TV, the ball is in a superposition state of scoring and not scoring.

The principle of inaccuracy: whether the ball goes in or not, you can never measure it.

Observer Principle: As long as you observe, you will inevitably see a result, but this result is immediate.

Do you understand?

Pol is saying that it was the great philosopher who planted flowers and created quantum mechanics - one day 500 years ago, the Ming Dynasty philosopher Wang Mingyang traveled to Nanzhen with his friend, and the friend asked:

"There is nothing outside the heart in the world, such flowers and trees, blooming and falling in the deep mountains, what does it have to do with my heart?"

Wang Mingyang replied:

"You didn't see this flower, this flower and your heart are in silence, you come to see this flower, the color of this flower is understood for a while......"

This is the famous "Heart Without Foreign Objects"!

Typical idealism, we can still be shocked by the meticulous logic of these idealist philosophers.

So, Boll is tireless in destroying people~

A more accurate description would be:

As long as a microscopic particle is in an environment where it is 'likely to be measured', it will automatically become one of many possible forms, without waiting for the 'observer' to be in place.

, no?

Professor Xue said that it was, so he made a cat.

The cat, he said, is either dead or alive.

There can never be a cat in a superposition of immortal and inanimate states.

Horrifyingly, there is no way to falsify this, and the only way is to make the cat.

So, in 1996, more than 60 years after the birth of the cat, the American Monroe (male) used a single glass ion to create the cat (one will spin, one will spin) - it was the first time in human history to see a living quantum superposition state.

Thus, the first theorem in human history that required the use of probability and statistics was born (I'm not sure).

That is to say, the cat is neither dead nor alive, until the moment we see it, it is a kind of its immediate form.

In 2012, Professor Pan Jianwei established an 8-photon superposition state, and in 16 years, only 7 photons were added.

Superposition!

Remember Professor Xue's half-dead, dead and alive cat?

Putting this cat that is both 0 and 1 into a specific computational model is called:

Quantum computers.

Quantum superposition has superpowers that traditional computing can't even dream of.

Illustrate:

If you walk in front of the stick figure woman is pretty.

Run A logic - go forward and ask for a WeChat ID.

If she's ugly.

Run the B logic – turn around and go.

Classical machines do it only once according to logic.

But for a quantum computer, it is executed twice, that is, no matter whether the woman is beautiful or ugly, it has to go up and slap it once!

Examples of switching back to traditional science:

Increase the number of qubits to two:

Variable X=00, run A.

Variable X=01, run B.

Variable X=10, run C.

Variable X=11, run D.

With two qubits, a classical computer needs to run four times, but a quantum computer only needs one.

See the severity of the problem?

When the number of qubits increases to 100, all the computers on Earth today will need to run for 1 million years at the same time, and quantum computers will only need ......

A few minutes!

Smoke fills the air, sparks fly.

The human scientists on the earth are raising the hammer in their hands and frantically beating an iron embryo - they want to make the sharpest spear, they want to pierce the sky, they want to smash the financial secrecy system that human beings rely on for normal operation!

Thus, a theoretically absolutely safe shield came into being:

Quantum-encrypted communication!

（PS:

1. Quantum is a mistranslation, the word quantity means small, microscopically small, it can be small particles such as particles and photons.

2. Quantum computers have a lot of professional vocabulary and technology, and the following things will also be used, no matter how deep I am, I am confused, there is nothing to be ashamed of.

3. Please note that quantum encrypted communication, according to Shannon's assumption, is theoretically absolutely secure. ）

............

The text continues:

In 1936, Xue Yemon, who was busy dealing with many ex-girlfriends and cats, discovered something even stranger, but at the time, almost no one paid attention to the problem.

Please remember this beast, because whether it is the cat, or the theory and noun of quantum mechanics he proposed, all of them are based on the beast's .......

Thought Experiment!

And a few decades later, the European Nuclear Center (CERN) did just that:

They want to use the particle collider to see how many children are in the big belly of the atomic nucleus, and follow Professor Xue's thought experiment under the confirmation.

Something more terrifying than Uncle Wuzhu is a robot has happened again......

“Duang~”

One part of the particles that are hit is two (in most cases).

It becomes A particle, B particle.

According to the conservation of energy, one flies forward, the other definitely flies backward, one turns down, and the other definitely goes up.

However, no matter how they fly and how they move, they are random, and they will not stabilize in a state unless you observe them.

In Professor Xue's thought experiment, this situation is called: the superposition of twin particles.

In this superposition state, what one particle looks like when it is observed, the other must be the complete opposite, and Professor Xue has given the two particle forms whose fates are secretly connected, and has given a sexier name: quantum entanglement.

Einstein blew up, the scientific community all over the world went crazy, philosophers began to enter the scene, you come and go, swords and swords, so lively.

As the greatest scientific community, Einstein published and perfected the special and general theory of relativity at the age of 35, at that time, he was still a handsome and dashing little fresh meat, and the image we see of an old man with explosive hair is the image of that guy after studying quantum mechanics for 30 years.

What happened to blow up this dude?

It all started with "quantum entanglement".

.........

Next, let's make the most important character in our primary school textbooks appear - Xiao Ming.

Xiao Ming grew up and couldn't find his daughter-in-law, one day, his mother brought two brides wearing red hijabs to Xiao Ming, the two women were beautiful and the other was ugly, and then handed one of them to him, and asked Xiao Ming to take the woman to the end of the universe!

According to quantum entanglement, that is, the principle of quantum mechanics, the beauty and ugliness of the woman in his mother's hand is not decided by his mother, but at the end of the universe, Xiao Ming lifted the red hijab and saw the beautiful woman for a moment, and then the signal passed through the entire universe and instantly came to his mother's mind, telling her that the woman in your hand is ugly.

How fast is this?

Infinitely fast.

What is it called?

Beyond the distance!

Or faster-than-light!

What would it be like if it were applied to the field of communications?

This is the quantum mechanics of the microscopic world, and if everything was true at the time, then it would challenge Einstein's macroscopic theory of general relativity, and the physical system of the whole world would collapse.

In Einstein's view, there was no such thing as an immortal cat, everything was black and white, that is, when a woman was handed over to Xiao Ming, she was already destined to be a beautiful woman.

The reason why we don't know is that there must be any hidden variables, as long as we find hidden variables, then this world will have no secrets for us!

Albert Einstein denounced the situation as a ghostly telepathic effect.

Writing this, I am extremely proud, it turns out that I am a normal person like Albert Einstein!

What is dead and alive, what is half-dead, what probability, what statistics, all die!

Pity.......

Are there hidden variables?

No!

There are only two words - entanglement.

30 years later, Einstein's follower, ultimate hacker, engineer Bell dug up a cosmic bug that had been hidden for 30 years - Bell's inequality.

I don't understand this inequality of conversion from 2D to 3D.

However, its birth announced the controversy over quantum locality, from philosophical speculation to empirical and falsified scientific theories.

20 Years Later (1982)

The Frenchman Azpecht was the first to successfully verify Bell's inequality and concluded:

Quantum mechanics wins, ghostly over-distance action, it's true!

.........

However, isn't this a violation of the theory of relativity (no information and matter can exceed the speed of light) kilometers?

No!

Because although the information is transmitted instantaneously, in order to remove the garbled characters and extract the real content, it is still necessary to send the image in the traditional way that does not exceed the speed of light.

This involves a higher level of technical terms such as entanglement, fault tolerance, and error correction.

The faster-than-light problem that broke Einstein's heart turned out to be unfounded!

.........

Superposition, quantum computing, entanglement, quantum communication.

They are also intertwined with each other, without distinguishing from each other.

As for the implementation principle, I am still in confusion, if I can understand even a little bit, I will invite the island country Golden Lock and nag you a few words.

Therefore, when everyone plays landlord and sees the 'K' (founder of modern cryptography, Julius Caesar), don't worry about the security of our modern financial system.

Because of quantum mechanics, the whole world is in a state of confusion.

Pol: "If anyone isn't amazed by quantum mechanics, they don't understand quantum mechanics." “

Albert Einstein: "I think about quantum mechanics a hundred times longer than general relativity, but I still don't understand it." ”

Feynman: "Nobody understands quantum mechanics!"

Pan Jianwei: "If I can figure out why there is quantum entanglement, I can die now!"

The future, far away.

The future is here!

...........

Write at the end:

1, 21 world, mathematicians appeared.

In the established mathematical theoretical model (note that it is theoretical), the whole universe is filled with quantum entanglement, and when it disappears, the universe collapses!

2. Imagine a number '8', and then turn sideways and pull its two eggs hard, you will get the symbol of '∞' infinity, which is the mathematical model (theory) of quantum entanglement.

What do you think it looks like?

Einstein Rosen Bridge.

That is, wormholes (two unreachable black holes that can be connected by channels in space-time).

If this is true, then the most mysterious phenomenon of quantum entanglement, "Beyond Distance", does not actually exceed the speed of light, but like a wormhole, beyond time and space!

Mathematicians speculate that quantum entanglement may be a miniature wormhole.

3. Today is December 12th, Shopping Day. But even more memorable than the shopping festival is that 117 years ago, Marconi received the first radio signal in human history across the Atlantic.

And three years ago, in August, the world's first quantum communication MSI Micius took off.

Now, although some people say that it has failed and is just the product of fraudulent funding, I don't agree with it at all, because at least we are in it.

Professor Pan Jianwei is an applied scientist, he may not be close to the Nobel Prize, but among the popular science books I have read, he is the only Chinese scientist who has appeared on our land!

4. Some people say that quantum computing and communication need hundreds of Nobel prizes to lay the foundation, and talking about it now is just the tireless pursuit of human beings.

So, what is sensational, shocking, and on the media!

I wonder if there really is such a genius born and understand what quantum entanglement is, maybe ........

The universe will open its doors to humanity.

5. Happy Shopping Festival!

It's almost the New Year, keep your wallet!

6. About Updates:

Most people, in order to escape from real thinking, are willing to do anything!

- Wang Xing!

I wrote 5,000 words in the morning, and 2,000 words of updates, I have to write for a day........

7. What am I talking about?

It's because personal PCs are still in the mainstream position, Zhao Song's toss is not useless, cloud computing, big data, and 5G are not human heads.

Some book lovers don't think about these profound things, let's honestly carry them in the category of urban rebirth, don't go to grab fantasy jobs, until.....

The day of 404.
