Starting a dollar spike system

This is the number of explosions in accordance with the index law!

When a quantum computer consists of 10 quantum bits coupled together, its calculation capabilities are equivalent to a traditional computer composed of 2 ^ 10 = 1024 switches (bits).

If a quantum computer has a 1000 quantum bit memory, then it works like a traditional computer having 2 ^ 1000 = 10 ^ 301 memory.

10 ^ 301, after 301 0! This number is much larger than the number of all particles in the entire universe!

That is, even if all particles in the universe are used to make a traditional computer, it is far from such a quantum computer!

Of course, it is necessary to overcome the difficulty in which 1000 quantum bits are in the controllable stack of each other. There are too many difficulties to overcome!

The quantum computer is too powerful.

Some people have played a bit: If the speed of the traditional computer is a bicycle, the speed of the quantum computer is like a plane.

Use billion "Tianhe No. 2" supercomputer to solve a millions of millions of variables, the time required for 100 years.

Use a trillion quantum computer to solve the same equation, just 0.01 seconds.

The quantum calculation speed is faster than the classic computer, and the prototype machine has made a solid first step in this theoretical change, and the quantum computer truly pushed the quantum compulsion to the classic computer competition.

So how do I understand quantum computers, I will let everyone, what is the modern quantum computer in the end of ten minutes.

Jiang Fan said while starting on the blackboard:

First, we know that the computer is composed of the basic components, that is, the logic gate of the circuit, and each logic unit consists of a transistor, and only some simple operations such as the addition and subtraction.

The transistor is the most basic unit that allows computer to process data. From functional, it is like a switch, blocking or allow current to pass, and high and low electrical signals constitute data, ie bits - for a bit, there are 0 and 1 Two kinds. The more bit digits, the greater the number that can be expressed.

Today, 1 transistor can have a few nanometers. Since small to only the size of several atoms.

Electronics sometimes ignore the impede it directly and directly through a closed triode switch (simply, it will leak electric, lost switch role), this magical super natural phenomenon is called: quantum tunneling effect (also called quantum tunneling effect).

In the quantum field, traditional physics is no longer applicable, so traditional computers cannot work properly.

At present, human beings have encountered a real physical barrier, and Moore's law has also been invalid.

The next scientist is to do, using quantum characteristics to study quantum computers.

In quantum computers, quantum bits can be set to any one of 0 and 1.

The system can exist 0 and 1 state, as the photon can be horizontally or vertically polarized (the direction of electromagnetic waves and the electromagnetic field perpendicular to each other are perpendicular to each other, and we call the electric wave of the electric wave).

In the quantum world, quantum bits can be in multiple states at the same time, which can be any of several normalized linear combinations in several different quantum states, which we often say: quantum superposition state

However, once you determine its value by the photon detector, it will become one of the horizontal or vertical polarization state.

That is, as long as it is not observed by the detector, the quantum bits are in the superposition state (simultaneously equal to 0 and 1) without predicting its value.

At that moment, it will collapse one of two states (refer to Schrödinger's cat.)

One N-bit quantum computer = [formula] The traditional computer parallel calculation of the N bit.

It can be seen that the advantages of each one (logic bits), quantum computers are exponentially increased.

More interesting is! Quantum Bit has an incredible characteristic: it can be in quantum entanglement state.

. . . . . . . . . .

Through these simulations, we can help us understand the characteristics of various proteins, resulting in the possibility of medical changes, saving human.

Jiang Fan foot talked about approaching an hour, this stopped.

Guo Dongling poured a glass of water and handed him.

"Thank you."

After picking up the water cup, Jiang Fan put the water in the cup, drunk into the abdomen, and then let's find a position to sit down and want everyone to digest.

"Mr. Jiang, you are going to be wonderful!" Dai Jianzhong Dynasty toward Jiangfan thumbs up, and his face with excited expressions.

"I will so much, I hope that your science and technology, you can study through the transparent, these things, I haven't given my research institute."

"Mr. Jiang, rest assured, wait for us to digest what you said, we will start to make it up with a quantum computer."

Quantum computers will have a lot of benefits as long as they develop.

Technology will also get greater progress.

"You are too traditional, sometimes, you should jump out of traditional concepts, and take a higher level."

Jiang Fan shook his head smiled and proposed it.

"Haha, after this said, I really feel that our thinking is too traditional. I used to have a lot of things. We never thought about it, and I have been in research. After the reminder of Mr. Jiang, I feel that I feel before. I have a mistake, there are many places wrong. "

"Well, you can understand it."

"The progress of science and technology is not relying on one, but relying on everyone, relying on the team."

"Only everyone is concentric, studying technology to make technologies more improved."

Guo Dongling is a smile, she is still the first time I saw the dean by a young man lesson.

However, this young people can, but also be powerful than anyone in their science and technology, it is awesome. She believes that even if they are well-known scientists, they will listen to Jiangfan like a student in front of Jiangfan.

Such a young man is only twenty years old, and people are so handsome. Guo Dongling's eyes flashed with small stars.

This class has taken more than two hours, and Jiang Fan has roughly speaking about 10%.

If you want to finish all, then take a few days.

Of course, even if he finished, the scientific and technology institutes want to completely digest, and it is estimated that it has also been fully digested for a few months.

Because this is technology, not other things.

Not that kind, you can figure out what they will immediately.

"Finally, it is over." Jiang Fan leaned against the chair and loose tone.

"Haha, Mr. Jiang, tired." Tang Zhenhai appeared in Jiangfan.

"Mr. Tang, give them these things, it is not easy, say that I have a dry tongue." Jiang Failuan smiled.

"Indeed, but I didn't expect that Mr. Jiang's talents can be more powerful than I think, Mr. Jiang, can explain such a deep principle for them, this is a lot of efforts to technology."
