Chapter 909 The final destination
"Is there?" Yang Dongsheng touched his face.

"En!" The little tiger nodded seriously.

"Eat your food!" Zhou Ying slapped the little tiger on the head.

She was a little depressed. Women always age faster than men.

This situation is especially evident in the entertainment industry, where some male and female stars act as lovers first, and then as siblings.

Acting and acting, and finally became the mother-in-law and son-in-law.

After dinner, Yang Dongsheng went into the study alone.

Looking in the mirror, I took a careful look.

In fact, he himself had discovered this problem before, but he was not sure at the time.

Looking at it now, compared with the same period last year, he is almost a year younger.

It was as if time had flown backwards on him!
Calculate the time when this happens, which happens to be the time when the reverse funnel is opened on the [-]D map.

If it is really related to opening the reverse funnel, this situation must continue to develop.

You have to find a way to cover it up!

Yang Dongsheng asked the office to find him an image designer.

The designer redesigned his hairstyle and asked him to comb his hair back.

He also suggested that he wear a pair of black-rimmed glasses to look more mature.

If you still want to look older, you can also grow a beard, dye gray hair... There are many skills.

……

The time has entered 2021. After more than three years of raging, the toxicity of the virus has become very small.

The world became active again, and Dongsheng Semiconductor also ushered in a major event.

Except for the optical quantum computer of the University of Science and Technology, most of the currently announced quantum computer projects use the superconducting technology route.

The core component of a superconducting quantum computer, the "Josephson junction", has a very simple structure.

Sandwich a thin piece of aluminum oxide between two pieces of aluminum, and then lower the temperature to the superconducting critical temperature of aluminum - below minus 271.76 degrees...

When two superconductors are separated by a very thin layer of insulator, usually only one or two nanometers, electrons can pass through the insulating layer. This is the "Josephson effect".

The Josephson effect is a typical macroscopic quantum effect.

It's not that hard to make a Josephson knot!
For quantum computers, the biggest difficulty is error correction.

Quantum is very sensitive to external environment and noise.

Many interferences that are considered insignificant by electronic computers will directly cause the state of qubits to change, which in turn will lead to errors in calculation results.

As the calculation proceeds, this error will accumulate step by step.

In the end, the deviation of the calculation results is unacceptable.

It can be said that scientists have spent most of their research on quantum computers over the years on error correction.

To correct errors, scientists have proposed various encoding and decoding schemes.

Dongsheng Semiconductor insists on using traditional physical methods for error correction.

The advantage of the physical method is simplicity, but for a quantum computer using this scheme, a logical qubit requires multiple redundant physical bits for error correction.

Traditional Josephson junctions are bulky and require liquid helium cooling.

Doing so requires a huge hardware overhead.

But from another perspective, as long as the size and cost of the Josephson junction can be suppressed, a sufficient number of physical bits can be produced.

This error correction scheme is the simplest and most effective.

Dongsheng Semiconductor uses silicon carbide as the base material - high-purity silicon carbide is an insulator, and silicon carbide used for chips is added with other materials to become a semiconductor.

First, like making ordinary chips, microstructures are engraved on silicon carbide.

Liquid metal hydrogen is then coated on top.

After cooling, cut and package.

Through this method, they can construct tens of millions or even hundreds of millions of Josephson junctions on an area of ​​one square millimeter.

Multiple physical bits are then combined into one logical bit.

Using this method, Dongsheng Semiconductor has produced a quantum chip containing 1000 million logic bits.

Compared with other countries that have launched or are currently developing quantum computers with only a dozen or dozens of bits.

Dongsheng Semiconductor is half a century ahead of them.

It's just that the pass rate is still too low, and only two qualified chips were obtained in the first batch of dozens of wafers.

Moreover, it also blew up a production line built with huge sums of money—metal hydrogen is in a metastable state, and its explosive power is 30 to 40 times greater than that of TNT.

But it's all worth it!
Theoretically, the computing power of one such chip is hundreds of billions of billions of times higher than the combined computing power of all the computers that have been manufactured in the world.

Dongsheng Pharmaceutical developed dozens of new drugs within a week using computers equipped with such chips.

Dongsheng Heavy Industry uses it to optimize the shape of gas turbine blades, pushing the thermal efficiency to the extreme.

The encrypted information of various countries, whether using 1024-bit encryption, or secretly using the quantum computer they just created for encryption.

In front of them, it is completely transparent.

They can steal these secrets without alarming each other.

After installing the face recognition system, they can call networked cameras all over the world, as well as networked mobile phones and cash machine cameras.

Monitor the world.

Dongsheng Semiconductor has achieved the so-called "quantum supremacy", but Yang Dongsheng did not announce it.

The biggest usefulness is not these!
Quantum computers themselves have parallel computing capabilities, so the most suitable for quantum computers is artificial intelligence that also uses parallel computing.

Today they will conduct another experiment.

Another qualified chip was installed in a completely physically isolated computer in the basement of Dongsheng Building.

This basement shielded all electromagnetic wave signals, and everyone handed over their electronic equipment before entering the room.

The experiment they are going to conduct today is to load their latest artificial intelligence software onto this computer.

After everything was ready, Yang Dongsheng nodded, "Let's start!"

Yang Dongsheng secretly selected the metal hydrogen in the chip, as long as it dared to rebel, Yang Dongsheng would extract all the metal hydrogen.

After the software is loaded, technicians start testing.

……

After some testing, the technician shook his head with some regret. Although this computer performed outstandingly, it did not awaken self-awareness.

This situation is both disappointing and unexpected.

The mouse brain has 8500 million neurons, and the human brain has more than 100 billion neurons.

Moreover, the information exchange efficiency of the brain is not known to be many times higher than that of a computer.

It is obviously a luxury to rely on the current technology to make artificial intelligence awaken self-awareness.

……

At the end of 2021, a large passenger plane landed at Grain Coast XXXX International Airport
The current population of the entire Grain Coast has recovered to 250 million.

About half of them are black, and the other half are white and yellow.

The industries on the Grain Coast are mainly metallurgy, shipbuilding, mining, and petrochemicals.

In terms of agriculture, rice, corn, soybeans, rubber, and cocoa are grown.

Last year, the GDP reached 300 billion U.S. dollars, with an average per capita of 1.2 U.S. dollars.

have reached the level of middle-income countries.

The Grain Coast also underwent sweeping political reforms.

The presidential term is changed to 7 years and cannot be re-elected.

Although popular elections are still implemented, the candidates must have served as chief officials in the higher-level government, or as deputy or major department leaders in the same-level government.

And more than one term of administrative experience.

Prevent political amateurs from reaching the sky in one step.

Debates during the campaign are only allowed on designated official media.

Any other form of publicity is strictly prohibited, including but not limited to street speeches, advertisements, and banquets.

Members of Parliament at all levels are part-time, no office space, no salary.

After getting off the plane, Yang Dongsheng's first feeling from Grain Coast was that it was a little hot.

The weather forecast shows that the maximum temperature during the day will reach 34 degrees today.

Grain Coast has arranged strict security measures.

As soon as their plane entered the airspace, four Su-30 fighter jets closely guarded it on both sides.

After getting off the plane, special cars and guards were arranged for them.

The car left the airport, and the sights on both sides of the road were impressive.

The spacious two-way 10-lane highway, lined with tropical trees on both sides, stretches all the way to the city center.

After entering the urban area, there are no groups of children playing football on the muddy ground with bare feet that are common in Africa on both sides of the road.

As soon as they saw a foreigner, they gathered around and followed the car, shouting "money" while running.

There was not a single child on the road, and it was time for class.

Except for some pedestrians and vehicles who waved enthusiastically at them, most of them left in a hurry.

There is no poverty but happiness boasted by the western media, only discipline and busyness!

After arriving at the hotel and having a short rest, everyone attended the reception dinner held by XX Mansion.

Freddy Krueger delivered a speech.

The host and guest enjoy themselves!

After the dinner, Yang Dongsheng came to a conference room on the pretext of going out for a walk.

A circle of people in the conference room stood up in unison, and Yang Dongsheng saw James Whistler, Freddie Krueger, Michael Myers, Jason Voorhees...

There are many others he does not know.

On the [-]D map, these figures are all golden yellow.

"You are finally here!" James Whistler burst into tears with excitement.

"Wait a few more years, I may be here permanently in the future! At that time, don't bother you!" Yang Dongsheng took off his glasses.

He took out a tissue and wiped it on his face, restoring his original appearance.

At this point he looked to be in his twenties.

The flow of time is not uniform, and the flow of time has accelerated in the past two years.

Just when Yang Dongsheng was worried about whether he would turn back into a baby, the backflow began to slow down in the second half of this year.

No matter how old he is, it is impossible for Yang Dongsheng to die in China.

In the future, the Grain Coast will be his final destination!
