Chapter 1178

There was a strange silence on the other end of the phone.

As if there was no signal, there was no sound for a while.

However, when Lu Zhou hesitated for a moment to remind director Li on the opposite side of the phone that he was still on the phone, there was a voice from Duan on the other end of the phone, as if something had fallen on the table.

soon the cell phone was Kwai picked up from the coffee table.

"What do you do, Lao Liu --"

"what do you say? Has the problem of topological quantum computing been solved? What's the problem? How do you deal with it? And the Hall effect -- "

listening to the excited and strange voice from the other end of the phone, Lu Zhou was slightly stunned and asked with a frown.

"You are?"

There was a slight pause in the firecracker like sound.

With a deep breath, it calmed down.

"I'm Liu Changqing from the Institute of semiconductors, Chinese Academy of Sciences! If it's convenient, please ask academician Lu to answer for me. "

Academician Liu.

Hearing the name, Lu Zhou thought about it for a while, and a sudden expression appeared on his face.

Deputy director of Semiconductor Research Institute of Chinese Academy of Sciences, director of IC Design Center, director of national key special project of "quantum control and quantum information", and one of participating experts of Longteng series chips.

He has heard Professor Wu Tianqun say the name several times before. Although he has not seen it, it is said that he is also a great bull in the domestic semiconductor industry. If so, it seems no problem to tell him.

“…… To put it simply, I have solved the problem of the instability of entangled quantum bits by using a special model insulator material including mayorana fermion. "

"Wait, what are you saying in detail? I know the nature of mayorana fermio. No matter how you find it in the materials containing model insulator How can it be solved? "

The voice at the other end of the phone was incoherent.

Hearing this series of questions, Lu Zhou sighed with some headache and said simply and comprehensively.

"It's too troublesome to talk on the phone. If you are interested, just come to Jinling."

……

Lu Zhou didn't expect that academician Liu was so efficient that he arrived at Jinling from Shangjing the next day.

At the same time, academician Liu, director Li, and experts in quantum computer research from the Institute of semiconductors, Chinese Academy of Sciences came here.

Facing a group of people's eager vision, Lu Zhou smiled and said nothing, so he took them to a multimedia screening room and stood in front of a whiteboard.

“…… Before we start, we need to clarify a basic concept. The topological properties of matter do not change by continuous stretching or bending, except by tearing or connecting to new places. "

Academician Liu pushed his glasses and said solemnly.

"We all know And then? "

"The same applies to quantum mechanics Of course, these are very basic things. What's not basic is how we use these properties to achieve the results we want. "

As he said that, Lu Zhou turned around, picked up the electronic pen and waved it to the whiteboard. The six grid lines were just like those on the white board, directly printed on the whiteboard.

Looking at the scene of science fiction, including academician Liu, a group of experts from the Chinese Academy of Sciences, all of them were surprised.

Noticing the expression on their faces, Lu Zhou said with a smile.

"This is a gadget I made in my spare time, mainly for the convenience of my own blackboard writing After all, many things in physics are different from mathematics. Many things don't seem so intuitive. A convenient blackboard writing tool can save me at least the time of taking ruler and eraser. "

In fact, it doesn't have any special technical content, that is, a white board with touch and imaging functions, plus a smart camera with motion recognition function. A long time ago, similar things appeared in the MIT classroom, but the function of that thing is not as rich as his model, and its operability is far less flexible than his model.

"Back to the point, let's go back to our previous topic." "The key to solving the problem of quantum computing is how to overcome the interference of environmental noise on subatoms and prevent quantum bits from collapsing in the environmental disturbance," Lu continued

The moment the voice fell, he waved the electronic pen in his hand.

The electronic pen was just like a baton. Under its command, a row of black dots appeared on the white board covered by six grids.

These black dots represent subatomic particles, which move around an invisible circular orbit with uniform speed.

All the people under the stage are focused on the whiteboard,

" This kind of quantum system has the nature of immune decoherence and can accurately perform the properties of preset algorithm"Having said so much, I'd better demonstrate it directly..."

As he spoke, the boat waved to the door, and a drone came unsteadily, placing a small box firmly in his hand.

Shaking the box, the boat gently put it on the table.

"This is a simple scientific calculator. According to my compiled program, it can only do one operation By the way, do any of you have computers? "

I don't know what medicine Lu Zhou sold in his stomach. Academician Liu hesitated and nodded.

"I have."

"Good. I'll give it to you."

With that, Lu Zhou returned the small box to the UAV, and then motioned for the UAV to fly to academician Liu and put the small box on his desk.

After taking a look at the small box and opening it, academician Liu was surprised to find that it contained a 10 key numeric keyboard and a simple display screen.

It's like a small calculator, but there's no sign of addition, subtraction, multiplication and division. There's an extra confirmation button, and I don't know what it's used for.

At this time, the boat continued to talk.

“…… As we all know, it only takes 0.3 seconds or less for a traditional computer to generate a 1024 bit prime number, and two are 0.6 seconds. It can be too fast to ignore to multiply the two. "

"But if, on the other hand, you take the product of two prime numbers apart, the same computer may not be able to handle it in three days and three nights."

In the moment when this sentence fell, there was a commotion in the classroom.

Many people 's faces, emerged a trace of surprise, or even shocked expression.

Looking at academician Liu, who seemed to have guessed something, Lu Zhou smiled and made a gesture of "please".

"Now you can use your own computer to randomly generate two of any size It's better to get prime numbers over 1024 bits and then find their products. "

"I believe it's easy for you."

"Finally, I hope you put that product into this box, and soon we will witness the miracle."

The Adam's Apple moved, and academician Liu's trembling voice was full of excitement.

"Don't you --"

looking at academician Liu, who has already started to emerge in his face, Lu Zhou doesn't speak, just smiles and nods.

"You'll have a try."

According to Lu Zhou, academician Liu quickly generated two large prime numbers of more than 1024 bits with his own computer, and input their products into the pocket calculator endlessly.

Other experts from the Chinese Academy of Sciences, as well as director Li, stood behind him and watched him continue the experiment.

After all, it's more than two thousand numbers. It took a long time to input.

When academician Liu finally finished all this and pressed the confirm button, the miracle happened in an instant!

There's no Carlton at all.

Just like a simple addition and subtraction method, the product of this large prime number is quickly divided into two prime factors.

Looking at the numbers on the display screen, not only academician Liu, but almost all the people around him were surprised.

A moment!

For the traditional computer, it takes several days to solve the problem, which is solved in less than a second!

Academician Liu's eyes widened completely, his mouth opened and closed, and he lost his words completely.

Before he came here, he thought that what Lu Zhou said solved the quantum bit entanglement collapse problem was only a theoretical solution.

But I didn't expect that when he was still confused about the theory, not only the theory, but also the specific samples were made by academician Lu.

It's not just the experts from the Chinese Academy of Sciences who are shocked, but also the director Li who is standing by and watching.

What kind of change will this technology bring to the world? He is shocked and has no room to think about it.

The only thing he knows now is one thing.

RSA encryption rules, which have been used for nearly half a century at least, can be completely withdrawn from the stage of history from today
