Scholar’s Advanced Technological System

The phone was strangely silent.

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

However, Lu Zhou hesitated for a moment, and was about to remind Director Li on the opposite side of the phone that he was still on the phone, and then a duang came from the other side of the phone, as if something had fallen on the table. .

The phone was quickly picked up from the coffee table.

"What are you doing, Willow--"

"What do you say? The problem of topological quantum computing is solved? What problem? How do you deal with decoherence? And the Hall effect--"

Listening to the excited and unfamiliar voice from the other side of the phone, Lu Zhou frowned slightly and asked with a frown.

"you are?"

The flamboyant sound fainted.

With a deep breath, he calmed down.

"I'm Liu Changqing from the Institute of Semiconductors of the Chinese Academy of Sciences! If it is convenient, I will also ask Academician Lu to answer for me."

Academician Liu.

Hearing this name, Lu Zhou thought for a while, a stunned expression appeared on his face.

The deputy director of the Institute of Semiconductors of the Chinese Academy of Sciences, the director of the IC design center, the person in charge of the national key special project of "quantum regulation and quantum information", and also one of the participating experts of Longteng series chips.

He had heard Professor Wu Tianqun talk about the name several times before. Although he hadn't seen it before, it was said that he was also a great bull in the domestic semiconductor industry. If he said that, it seemed that there was nothing wrong with him.

"... In simple terms, it is through a special model insulator material containing Mayorana fermions that I can solve the problem of unstable entanglement of qubits."

"Wait a bit more, you know? The characteristics of Mayorana Fermion, I know, no matter how you find it in the material that includes model insulators ... how did it work out?"

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

After hearing this series of questions, Lu Zhou sighed with a headache and said concisely.

"It's too much trouble talking on the phone. If you are interested, come directly to Jinling."

...

Lu Zhou did not expect that the academician Liu was so efficient that he rushed from Shangjing to Jinling the next day.

At the same time, not only Academician Liu, but also Director Li, and experts in quantum computer research at the Semiconductor Research Institute of the Chinese Academy of Sciences.

Facing the eager eyes of a group of people, Lu Zhou smiled and said nothing, so he took them to a multimedia projection room, and he was standing in front of a whiteboard.

"... Before we start explaining, we must first clarify a basic concept. The topological properties of matter will not be changed by continuous stretching or bending, unless it is torn or connected to a new place."

Academician Liu pushed his glasses and said solemnly.

"We all know ... then what?"

"This concept is also extended to quantum mechanics ... Of course, these are very basic things. What is not basic is how we use this series of properties to achieve the results we want."

With that said, Lu Zhou turned around and picked up the electronic pen and waved it toward the whiteboard twice. The six-grid pattern was printed on the whiteboard as if it had grown from the white panel.

Looking at this sci-fi scene, including academician Liu, a group of experts from the Chinese Academy of Sciences, all looked surprised.

Noting the expressions on their faces, Lu Zhou smiled and said.

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

In fact, this gadget doesn't have any special technical content. It is a whiteboard with touch and display functions, plus a smart camera with motion recognition. A long time ago, something similar appeared in MIT's classroom, but the function of the gadget was not as rich and flexible as his model.

"Let's get back to business, let's go back to our previous topic." The electronic pen in his hand lightly tapped on the whiteboard, Lu Zhou continued, "The key to solving the problem of quantum computing is how to overcome the interference of environmental noise on subatoms and prevent Qubits are collapsing in environmental disturbances. "

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

I saw that the electronic pen was like a baton. Under its orders, a row of uniform black dots quickly appeared on the six grid-covered white boards.

These black dots respectively represent subatomic particles, which are moving in uniform circular motions around invisible circular orbits.

Watching everyone in the audience staring intently at the whiteboard,

"... this kind of quantum system is naturally immune to decoherence, and can accurately perform preset algorithms."

"So much to say, I'll just show it ..."

As he said, Lu Zhou waved his hand toward the door, and a drone floated over it, resting a small box on his hand firmly.

Shaking the box in his hand, Lu Zhou placed it gently on the table.

"This is a simple scientific calculator. According to the program I compiled in advance, it can only perform one kind of calculation ... By the way, do you have a computer?"

Do not know what medicine Lu Lu's stomach sold, Academician Liu hesitated and nodded.

"I brought it."

"Good, then I leave it to you."

Then, Lu Zhou returned the small box to the drone, and then signaled the drone to fly to Academician Liu and put the small box on his desk.

After picking up the small box and glancing at it, Academician Liu was surprised to find that there was actually a 10-key numeric keyboard and a simple display screen.

It's like a small calculator, but without the addition, subtraction, multiplication and division symbols, an extra confirmation button, and I don't know what this thing is for.

At this time, Lu Zhou continued to speak.

"... We all know that it takes only 0.3 seconds or less for a traditional computer to generate a 1024-bit prime number. Two are 0.6 seconds. Multiplying the two can be negligible.

"But if the other way round is to take apart the product of two large prime numbers and use the same computer, it may not take three days and three nights to get it."

The moment the words fell, a commotion sounded in the classroom.

A look of surprise and even shock appeared on the faces of many people.

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

"Now you can use your computer to randomly generate two arbitrary sizes ... preferably more than 1024 primes, and then find their product."

"I believe it will be easy for you."

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

His throat moved, and Academician Liu's trembling voice was full of excitement.

"Don't-"

Looking at the surprised Academician Liu who had begun to appear on his face, Lu Zhou didn't say a word, just nodded with a smile.

"You'll know if you try."

Or the complex mood of interweaving doubts and excitement, Academician Liu, according to Lu Zhou said ~ www.readwn.com ~ using his own computer to quickly generate two large prime numbers over 1024 bits, and enter their product into this Pocket calculator.

And other experts from the Chinese Academy of Sciences, and Director Li, were standing behind him, watching him continue this experiment.

After all, it is more than two thousand digits, and the input work took a short time.

When Academician Liu finally did all this and pressed the confirmation button, a miracle happened in an instant!

Without the slightest stutter.

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

Looking at the numbers appearing on the display, not only Academician Liu, but almost everyone around him also made a surprised sound.

In an instant!

For a traditional computer, this problem that takes several days to solve is solved in less than a second!

Academician Liu's eyes were completely widened, and he opened and closed his mouth, completely losing his speech.

Before coming here, he originally thought that Lu Zhou's solution to the collapse of the entangled state of qubits was only a theoretical solution.

However, he did not expect that even when he was still confused about the theory, not only the theory, the academician Lu even made specific samples.

It wasn't just the experts from the Chinese Academy of Sciences that were in shock, and Director Li, who was standing by and watching.

What kind of change this technology will bring to the world, in shock, he has no room to think about it.

The only thing he knew was now.

The RSA encryption rules that have been used for at least half a century have been completely removed from the stage of history from today ...
