Chapter 227: Quantum entanglement and state superposition principle

There was excitement and excitement in Zhang Zhai's eyes. As for tiredness or something, it didn't exist!
If you make enough of the popularity, it means that the wisdom value is upgraded, and the wisdom value upgrade means that you can unlock new technology immediately!
What is the new black technology, quantum computer!
What is a quantum computer? It is known as the engine of the future technology. His real realization can bring about the era of the big technology explosion.
It can even bring about a new technological revolution that has a disruptive effect on the entire world.
In other words, if a quantum computer appears and is used on a large scale, it will mean that the entire world will enter a state of technological explosion, and various emerging technologies may emerge endlessly!
How could Zhang Zhai be unclear about the value of quantum computers. He even knows the value of quantum computers better than most people in this world.
After all, in addition to commercial use, in the field of scientific research, quantum computers are simply artifacts!
If it weren't for the image, Zhang Zhai would just want to yell at the air!
In Noah's laboratory, there was no one else except in this eye with excitement.
No one will know what is going on here, but history will clearly remember that this will be an important node in human history!
Host: Zhang Di
Wisdom: 190
Visibility: 86, 487, 313
Unlockable technology: None
The next stage can unlock technology: quantum supercomputers.
Mastery of technology: interactive holograms. , Artificial intelligence, new energy reserves, three new materials. Antigravity box
Zhang Zhai stared at the popularity of more than 80 million, suppressing excitement and excitement, and took a deep breath.
"Famousness +1"
"Famousness +1"
"Reputation +1 ..."
Zhang Zhai didn't hesitate at all. At this time, no wisdom value will be added, but when will it be!
After brushing, Zhang Zhai quickly clicked five times, letting the wisdom value go up five points.
Immediately afterwards, a cold sensation started from the tip of the toes, from the feet to the legs to the waist, instantly filling the head.
It's like pouring a bucket of cold water under the hot summer sun, soothing, and at the same time, Zhang Zhai can't hold back the excited mood and calm down again.
Zhang Zhai glanced at the remaining popularity, there were more than 50 million left, and upgrading to two hundred intellectual values ​​should be enough.
"Huh ... this time tomorrow, the quantum computer should also show its true colors."
"However, before that, I also seemed to be able to make some preparations in advance." Zhang Zhai narrowed his eyes and said to himself.
"Unlike antigravity, although a quantum computer is extremely important and difficult to implement at the same time, ... it has a complete theoretical basis, and even his theory has been proposed for decades." , Smiled slightly.
"Then let's have a good night's sleep, then get up ... learn!"
...
Zhaicheng Space Center, top floor, lounge.
Although Zhang Zhai was a little excited because of her excitement, when her head touched the pillow and her eyes were closed, the fatigue on her body made the excited spirit instantly sleepy. Within ten minutes, she fell asleep!
...
The next day, in the morning, Zhang Zhai Lounge.
Zhang Zhai sat on the ground casually, with a flush wall of books around his body.
At this moment, he has not continued to upgrade the wisdom value to 200 points. For integers on this kind of data, even Zhang Zhai, he has a subconscious sense of special significance.
Considering the possible side effects of the sudden increase in intelligence, Zhang Zhai decided to slow down for another day.
Of course, he did not waste time, but prepared for the upcoming black technology of quantum computers.
Holding the book in his hand, he read it with interest.
"Quantum entanglement and superposition of quantum states."
Zhang Zhai saw it very easily, because he studied physics. These two principles are just basic principles in quantum mechanics.
But he is still ready to revisit, because these two principles are the most basic principles that quantum computers and quantum communication can realize.
The first is quantum entanglement, for example.
"It's the equivalent of two telepathic twin brothers, one drowning in the water and the other standing on the shore, who can also feel suffocation.
Quantum entanglement is the two twins' quantum, and even at both ends of the universe, it can still carry information and affect each other. Ignore distance, ignore time. Zhang Zhai smiled and said to herself, as if explaining herself.
"If you apply this principle to the calculations of a computer, you can obviously say that the computer runs faster.
After all, according to the principle of quantum entanglement, information can be directly transmitted from point A to point b without any process. This speed can be said to be faster than the speed of light. To use a mysterious word, that is teleportation! Zhang Zhai smiled, then stretched out her hand, and thumped a few pages in a row.
"Then the principle of state superposition ..."
Zhang Zhai murmured, then suddenly couldn't help laughing.
Regarding the principle of state superposition, he thought of a classic story, and also a cat.
Basically everyone knows that it is Schrödinger's cat, which is the half-dead cat.
Before the box was opened, the cat was either alive or dead, or alive and dead, in a superimposed state of life and death.
You can say that it is dead or that it is alive. At this time, it expresses two meanings at the same time.
Only when we open the box will we be sure
Whether the cat is dead or alive, or the observation behavior of us opening the box, has caused the cat to die or live.
This phenomenon seems to be contrary to common sense. Einstein was once confused about this, and then said a classic sentence: "God does not roll the dice."
"God doesn't roll the dice ..."
Zhang Zhai touched the line with his hand, and then repeated.
"It's a pity ... but later scientific developments show that God is not only wayward in rolling dice!" Zhang Zhai shook her head and smiled.
This is the state superposition principle, and how does this principle have anything to do with quantum computers?
It's simple, because the principle of superposition of states is used in quantum computers.
Taking the smallest data unit bit as an example, in a classic computer, a bit unit can represent 0 or 1 and can only express 0 or ~ EbookFREE.me ~ non-zero or 1.
In other words, a classic computer can only express one piece of information at a time.
If he wants to express 0 and one at the same time, he needs two bit units.
But the quantum computer borrows the principle of superposition of states. Before the observer, he could have multiple states at the same time.
That is, one bit unit can express 0 and 1 at the same time, that is, express multiple data at the same time.
So a quantum computer can express multiple pieces of data at the same time.
In the case of one bit unit, perhaps this gap is not yet obvious.
When we increase this bit to 300.
Classical computers can express one of the 2 ^ 300 numbers at the same time.
If a classical computer wants to express all 2 ^ 300 numbers, it is obviously necessary to repeatedly extract 2 ^ 300 times.
The quantum computer does not need to do this at all. It can express all the contents of 2 ^ 300 numbers at the same time. It is estimated that the number set represented by 300 qubits has exceeded the synthesis of the number of atoms in the universe.
One can imagine how exaggerated this gap is.
Basically, the computing speed of classic computers and quantum computers is equivalent to bicycles and space battleships.
It is estimated that if a quantum computer is successfully manufactured, its computing speed can exceed the sum of the computing speeds of all current computers.
"Hey……"
Zhang Zhai spoke in a tone, "The principle that was born in the last century has not been realized until now. Quantum mechanics has been born for a hundred years. The development speed is really a bit slow."
Zhang Zhai shook her head and was quite sighed.
"Even now, there is still no improvement."
