Chapter 212 Virtual Space
"Is this a virtual brain machine?"

In Chensheng Science and Technology Industrial Park, a top-level scientific research laboratory, Lu Chen walked to R-101 next to him.

He held a silver-white helmet-shaped instrument in his hand. Unlike ordinary helmets, this silver-white helmet was densely covered with sophisticated electronic circuits.

Obviously, this is an experimental virtual headset.

R-101 nodded and said with a smile: "Yes, that's it. After our 95 human experiments, we have been able to achieve perfect human-computer interaction, and the virtual degree can be adjusted to more than [-]%."

Lu Chen didn't know what the concept of 101% virtuality was in R-95's mouth, so he decided to try it himself.

He looked at R-101 in a white coat, and asked with a smile, "Can I try?"

"of course can!"

R-101 nodded.

Under the guidance of the other party, Lu Chen quickly figured out how to use this helmet.

As a gadget that is aimed at the general public and whose popularity will be comparable to that of mobile phones and computers in the future, the operation difficulty of the virtual brain machine must not be too difficult.

Putting on the helmet, Lu Chen's vision was suddenly plunged into darkness.

Immediately afterwards, he found that he had completely lost his vision, not because of the occlusion in front of his eyes, but because of the sudden blackness in front of his eyes.

next moment.

A flash door appeared in front of him.

"This"

Lu Chen stretched out his hand, looked at his palm, and found that even the lines on his palm were clearly visible.

He raised his feet and walked towards the light door in front of him.

brush!
Passing through the light gate, the scene in front of him suddenly changed.

A scene of blue sky, white clouds and green grass appeared in front of him, and not far away was a lake like a blue gem.

The fragrance of fragrant grass and the smell of earth all hit his nostrils.

In the next second, the breeze gently brushed his cheek.

Lu Chen raised his head, and the dazzling sunlight shone into his eyes.

"Is this the virtual space created by your team?"

After feeling it carefully, Lu Chen suddenly asked.

At this time, a voice came from the sky: "Yes, this virtual space is based on the supercomputing center and data center of Chensheng Technology, but the supercomputing technology and data storage technology of Chensheng Technology are too backward. Now we can only create a virtual space of less than ten square kilometers."

Hearing this, Lu Chen couldn't help being silent.

If you want to create a complete virtual world, you can't do it with a virtual brain.

The core technology in the virtual brain machine is the neural connection technology, which is to allow human brain waves and machines to realize data interaction and transformation.

In other words, the information transmitted by the virtual brain machine to the human brain needs to be converted into the form of brain waves for the human brain to capture.

The information fed back by the human brain must also be received and translated into data by the virtual brain machine.

This neural connection technology has actually been researched by the Academy of Civilization Sciences for a long time, and it has achieved certain results.

Optical stealth suits are a typical example.

It's just that the optical stealth suit uses a special kind of biological cells, while the virtual brain machine is a complete electromechanical mechanism.

The gap between the two is like the gap between humans only knowing that dragonflies can fly and using this principle to create helicopters after knowing that dragonflies can fly.

Lu Chen experienced the virtual space highly praised by R-101, and then withdrew from it.

This newly created virtual space is very boring.

Although the scenery inside is very beautiful, it will still feel very boring if you look at it for a long time.

In the entire virtual space, apart from the sun, sky, white clouds, green grass, and lakes, there is no other scenery, which is very monotonous.

After leaving the virtual space and taking off his helmet, Lu Chen narrated his views to R-101.

R-101 pondered for a while, then raised his head and said: "Boss, the problem you mentioned is, in the final analysis, a problem of supercomputing technology and storage technology, and even temporary communication technology is enough. The data transmission efficiency of 5G technology It can reach up to 10G/s, which is almost enough to support ordinary virtual networks."

"Supercomputing technology and data storage technology."

Lu Chen raised his chin, "In your opinion, with the super-computing power of the Academy of Civilization and Science, can it solve the problem of running the virtual world in the future?"

Due to the emergence of room temperature superconducting materials, the supercomputing technology of the Civilization Academy of Sciences has made leaps and bounds compared with the outside world, although it has not reached the exaggerated computing power of quantum computers.

But compared with the world's number one Summit computer, its computing power is at least ten times that of the other.

Summit is a supercomputer at the Oak Ridge Laboratory in the United States. Its peak performance can reach 148.6 PFlops, which is 14.86 trillion operations per second.

And the unnamed supercomputer in Civilization Science City, which is Ling's main body, has a peak computing power of an exaggerated 217.33 trillion times, more than eighteen times that of the other party.

Of course, with a computing power gap of more than ten times, at the speed of supercomputing power updates and iterations, it will take at most ten years for the top supercomputing powers to catch up.

Before R-101 could answer, Lu Chen continued: "Or, do quantum computers have unique advantages in running virtual worlds?"

Hearing this question, R-101 shook his head with a wry smile.

He explained: "Boss, in the virtual world we want to create, more data changes need to be applied to comprehensive calculations, not exhaustive calculations."

Although Lu Chen's computer skills are not high, he is also a software professional, so he still has some knowledge in this area.

As we all know, the computing power potential of quantum computers is much greater than that of classical computers, or the two are not comparable at all. As long as quantum computers develop a little bit more mature, the computing power can completely explode classical computers.

But can quantum computers completely replace classical computers?
No!

Because quantum computers have great limitations.

The computing power advantage of quantum computers lies only in solving exhaustive calculations. What is exhaustive calculations, a simple explanation is to use powerful computing power to exhaust every possible situation, so as to achieve the purpose of solving.

This calculation method is also called brute force calculation.

Quantum computers are suitable for this and can only do this, because it can optimize the event complexity from o(2^n) to o(2^(n/2)), thereby greatly reducing the difficulty of calculation and exponentially increasing the computing power .

Generally speaking, the computing speed of a quantum computer can be measured by qubits, and the computing power of a qubit is 2^1.

According to this formula, as long as a quantum computer develops to more than a dozen qubits, its computing power can surpass the current classical computer.

As for dozens of qubits or even hundreds of qubits
That gap is probably the gap between apes and alien civilizations.

However, when a quantum computer is dealing with non-exhaustive calculations, it is a younger brother, no, to be precise, it is a baby, and the speed is very, very slow.

This is not a problem that can be solved by adding qubits, but caused by the limitations of quantum computers themselves.

Therefore, the future direction of computer development should be the combination of classical computers and quantum computers.

Quantum computers are responsible for exhaustive calculations, and classical computers are responsible for non-exhaustive calculations.

Closer to home.

The operation of the virtual world requires the processing of data, of course exhaustive calculation and non-exhaustive calculation coexist.

Therefore, it is impossible to solve all problems by relying on a quantum computer, even if the qubits of this quantum computer reach hundreds.
