Chapter 41 Three Generation Computers

Bai Moxie paused and hesitated, so he just started and observed the emperor’s expression. It seemed that he was really interested in listening to it, instead of agreeing casually. In fact, he was impatient... so he started to formally. To make a long story:

"... It can be said that the classic computer has a success or failure. It has inherent shortcomings. Instructions and data can only be stored in the memory. It is characterized by shared data and serial execution, so that parallel operations cannot be realized. With the development of human technology, Moore's Law has begun to become a'Moore bottleneck'.

It is not a natural law or law, but Moore’s optimistic estimate of the development of human computers in ancient times. As the crystal goes deeper and deeper into the nanometer direction, the deeper the quantum field, the greater the resistance to computer development. At the beginning, it was unable to maintain a stable time and doubled, and finally stagnated.

Until the computer revolution, non-von Neumann machines became the mainstream, DNA, cells, biological computers, and quantum computers appeared, and human computing power broke through an order of magnitude, thus gaining the foundation for entering the solar system...

I have to mention an interesting thing here, which is considered to be affected-there is a'Bitcoin' in the financial world, which has no value meaning in itself. It is purely that people give it value and make it linked to reality. In essence, it is just a random calculation. It's just a number, and this number is brought into a set of complex formulas, then it is Bitcoin... This thing is an extreme "financial monster" that evolved in the era of currency concepts.

Things became interesting after the emergence of quantum computers. In the past, von Neumann machines were serial in nature, and when multiple computers were connected together, in the end, they had to use random numbers to try formulas, and calculations became more and more difficult over time. , Because the total number of bitcoins is limited to 21 million, count one and one less.

However, any quantum computer can calculate all 21 million random numbers in one second. The Bitcoin system, which calculates the'workload' based on the amount of calculation, collapsed. In fact, the entire banking and financial system was affected to a certain extent. The encryption system of the previous generation of computers has failed, and a new bank bookkeeping system needs to be established. It is just that the governments of various countries have already done a good deal at that time, and there is no major problem. It just returns to the level of the original physical currency. The degree of barter..."

"Qing, wait a minute, why do you collude or not, and multi-machines are not combined? What is a combination?"

In fact, the emperor has these concepts, but knowledge and understanding are two different things. This is the reason why there is no endorsement in modern times, and most of them are actual hands-on assessments. What is the use of endorsement depends on whether you really can get started... Now The emperor pulled up a bunch of holographic screens, all of which were historical data on the development of the ancient three generations of computers, with text, pictures and videos, and even opened a popular science live channel.

"To put it simply, the analogy may be a bit inaccurate... Because von Neumann is a 01 mathematical model, all numbers can only line up in a line, go down, if you want to go fast, then split. But quantum Computers are different. In physics, due to quantum superposition, a quantum can be 0 and 1 at the same time. This is the basis of parallelism. 0 and 1 go the same way at the same time.

Take Bitcoin as an example. Bitcoin is a random number, and this random number corresponds to the key of a formula lock. Before, it was a key to try the lock, or prepare a bunch of locks and take a key to try. In order to improve efficiency, but the quantum computer came, it directly put infinite keys into the lock at the same time to try-this is parallel... So things ended up like that, and until today we still have'physical coins' for this reason. inside."

"It turns out that it's concise, concise, and flawed, but the brief description can only be so, but...the third era of computing..."

There was a knock on the door, and the conversation was interrupted. The clerk brought a sorbet platter with four colors of red, green, white, black and yellow. The AR label box showed that it was made of glutinous rice flour and ice cream milk. They are small white pieces, the red is red beans, the green is matcha, the black is sesame, and the yellow is soy flour. The flavor is rich and different.

A clerk dressed in ancient costumes, placed a stack of platter and a stack of sesame sweet potatoes in front of the emperor and Bai Moxie. After placing the bamboo chopsticks, he stepped back.

Obviously the emperor didn’t know when to order it. At this moment, he was holding his chopsticks together, saying: “This is a summer escape. You must taste it. Take a bite of ice and a bite of potato, cold in your mouth, and leave it smoothly. Harvesting it with tea is very good, very good, come—"

I'm afraid you are greedy by seeing my daughter happily eating ice cream?He complained in his heart, but said: "Please."

Sure enough, first a mouthful of sorbet, then a mouthful of roasted sweet potatoes at room temperature, and the last mouthful of hot tea. The overflowing dessert is sweet, dilute in the cooked sweetness of starch and become stable. The last mouthful of hot tea, the sweetness of the tea is bitter, and it is accepted. The sweetness before the middle, take away the last touch of sweetness, and prepare for the next bite of sorbet...This cycle repeats, not only the ice-heat cycle in temperature, but also a cycle in taste, which makes people addicted to it. One bite after another.

And what’s even better is that sorbets have different flavors with different sweetness and taste. Some are sweeter, some are more fragrant, some are far from the sweet potato flavor, and some are very close, allowing a smooth transition. , Each has its own beauty... It is indeed a new popular tea refreshment in modern times, something that the emperor would like, really has its own uniqueness.

Such a good thing, naturally, I want to share it with everyone, so I took a picture, with a note, and sent a "circle of friends"...Look at the live broadcast of Bai Lingling that is still being broadcast, they obviously received their own news. Started to twitter, and went to the next stop to eat.

After the ice cream shop manager came out, a clerk also came out to help. As the new employees ran over, the ice cream shop launched a mobile ice cream truck to distribute free ice cream to everyone, and everyone was happy to eat...

New employee girls still don’t dare to enjoy “free” things, and are trembling. Even if they take anything, they have to worry about the indoctrination for a while, and the acquired environment seems to take a while to adapt...Mug Lihua The suggestion is correct. First, a group of people will be sampled to observe and observe. Now there should be enough data to conduct targeted intensive social adaptation training for the remaining new employees.

"...Of course, the third generation of calculations?"

After eating and drinking for a while, the emperor was still thinking about Bai Moxie's computer story. In the teahouse, he should have tea while listening to the story.

Bai Moxie waved his hand and projected a few holographic images. A computer with a volume of one-to-one, floating in the air like a real thing, rotating and displaying. Then Bai Moxie controlled its deconstruction, let the computer disintegrate by itself, and unscrew the screw. , Scattered into various parts:

"This is an ancient classical quantum computer, which is very different from our current third-generation computer. Since our current computer is a processing model from childhood, it looks like a solid iron block inside and out. A base atom is a computing unit, a'computing crystal', which was impossible in ancient times. This is a technical bottleneck. Processing from large to small, from macro to micro, always meets a limit.

The suspension of ancient vehicles was a rigid body structure with elastic structures such as springs added, but we are now a rigid body. In the steel plate, atoms and atoms are made into an'elastic' structure, so we can obtain the internal structure of any substance according to our needs. , To make metal of level one to ten... a set of power armor is enough to destroy ancient civilization..."

The tenth grade metal process is extremely cumbersome and complex, requiring a large-scale industrial system, usually two or three planetary systems to complete, depending on the level of technology and industry. Although the production process is public knowledge in the human knowledge base, it is difficult to produce Very big.

During the galactic civil war, the small forces either owned more than a dozen star domains and nearly a hundred planetary systems built the Internet of Things and linked them together to produce grade ten metals, or they started construction on only one or two planetary systems and only produced them in more than a decade. From a ton-in a long history, a capital ship was the king and hegemony.

So before, the girls in the command joked that the Golden Knights could be divided into one country, and now the emperor calls Bai Moxie a warlord, all because of this...

In short, Bai Moxie did not take himself seriously. He, who has the academic literacy of researching and developing cutting-edge science and technology, knows very clearly how complicated the basic industrial system under the scientific pyramid is to the point of confusion. With his current Taohuawu In other words, everything depends on external imports. If the Galactic Empire is completely pulled into the trade blacklist, let alone the construction of the current teleportation array, the battleship has broken a hole, and there is no material to make up. Imagine a 6000km battleship. How many grade ten metals... Look at the pits and bumps of the pirate ships, all patches are because of this.

And to use this technology from small to large processing to the extreme, that is, to manufacture computer chips, Bai Moxie began to broadcast the holographic deconstruction process of cpu manufacturing in various eras.

"... During the von Neumann machine era, and even in the early days of the second generation of computers, the nano-scale chip production method is simply to engrave circuits on nano-scale silicon wafers. At 5 nanometers, it can engrave 5 nanometers in width The gully, the'gate line', and many things, in short, are the electrodes of the field effect tube, forming an effective physical'switch' NAND gate logic structure that can perform operations.

Our hair is about 0.05mm to 0.1mm, which is one hundred thousand nanometers, and then we have to step into the size of atoms. The uncertainty of quantum makes this traditional circuit-engraving process impossible.The earliest quantum computers relied on photons to manipulate atoms to create logical structures that could be physically realized."

"Where is the way."

"The first-generation computers are fairly simple. Starting from the second-generation computers, things have become more complicated, but with the basic concepts before, it’s actually easy to talk about-our current quantum computers are at the atomic scale, and their computational power It is directly related to the number of quantum superposition states and the number of entanglements. Specifically, at the physical application level, each quantum path, polarization, and angular momentum are related to the path strength, polarization, and angular momentum of other quantum. This is quantum entanglement.

Then we can easily measure the state of a quantum's path, and we can define it as either 1 or 0 at will. This is the nature of quantum superposition. Now suppose we have two such quantum entanglements, then we We have obtained 2 to the 2nd power of the key, if it is 3 triple entangled quantum, then it is 2 to the 3rd power of the key...

Similarly 0 and 1, the classic von Neumann computer can only represent one number. No matter how large the number is, it is only one. However, the quantum computer can represent 4 numbers at the same time. This is the magical place, and it can It's easily realized physically...

Our modern quantum computer is working hard in the direction of resolving superposition states and increasing the number of entanglements. If a quantum spin can be measured at every angle, then theoretically a computer with unlimited computing power will be obtained, because the circle One circle can be regarded as an infinite number of points... However, it cannot be realized in the first place in terms of energy, which violates the basic theorem of thermodynamics."

His Majesty the Emperor was listening to the storytelling, while leisurely scrolling through the holographic screen to look at the data, eating and drinking casually.Bai Moxie jumped and talked according to his own thoughts, and then inadvertently caught a glimpse of the information on a holographic screen—this holographic screen displaying historical documents, and it happened to have a paragraph like this—

In 2018, Pan Jianwei's team at the University of Science and Technology of China achieved 18 qubit entanglement.In other words, you get 2 to the 18th power, which is 262,144 keys.

Unexpectedly, before I traveled, the earth world already had such preliminary technical capabilities for quantum computers. Although in this era where the index is always pushed up to five or six digits, the double digit 18 does not seem to be a big deal, but In that year, at the very least, it verified the technical feasibility of this theory.

I’m about to come up with a quantum computer. I was thinking about backing in school to prepare for the college entrance examination. I thought I was invincible as the number one in the school every time I took the exam. It’s very satisfying to be called "Xue Ba" from up and down... Naive and cute, his eyes are too narrow...

I just hate that I was born too early, and look at the world now-everyone can build their own spaceships and get fit into space orbits. Cat slaves directly become the new human race of cat ears and cat tails.... Such an interesting era , It’s really not enough to play, why would anyone want to destroy it?

"...In short, biological cells are also atoms and molecules, and DNA also has computer properties. Once quantum computers are completed, the technology for manufacturing biological computers will mature. At the same time, it begins to involve the realm of'soul', what is human and what is thinking. First of all, One thing that is certain is that the human brain uses a parallel computing method.'Lenovo','dreams' and even the'subconscious' are examples. It is the phenomenon of multiple keys unlocking the lock at the same time." Bai Moxie concluded, "0, 1 cannot be carried." soul'……"
