Chapter 1179 Unscientific Speed

There was an eerie silence on the other end of the phone.

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

However, just when Lu Zhou hesitated for a moment, and was about to remind Director Li on the other side of the phone that he was still on the phone, Duang's sound came from the other end of the phone, as if something fell on the table. .

Soon the phone was hastily picked up from the coffee table.

"What are you doing, old Liu—"

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

Hearing the excited and unfamiliar voice from the other end of the phone, Lu Zhou froze slightly, frowned and asked.

"Who are you?"

The sound like a cannonball faltered slightly.

After taking a deep breath, he 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 this name, Lu Zhou thought for a while, and a dazed expression appeared on his face.

Deputy director of the Institute of Semiconductors of the Chinese Academy of Sciences, director of the IC Design Center, the person in charge of the national key project of "Quantum Control and Quantum Information", and one of the participating experts of the Longteng series of chips.

He had heard Professor Wu Tianqun mention this name a few times before. Although he had never seen it before, it is said that he is also a great leader in the domestic semiconductor industry. In this way, it seems that there is no problem telling him.

"... To put it simply, through a special model insulator material that contains Majorana fermions, I have solved the problem of unstable entangled states of qubits."

"Wait, can you be more specific? I know about the properties of Majorana fermions, and regardless of how you found them in materials containing model insulators... How, it's solved?"

The voice on the other end of the phone has become incoherent.

Hearing this series of questions, Lu Zhou sighed with some headaches, and said concisely.

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

...

Lu Zhou did not expect that 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 from the Institute of Semiconductors of the Chinese Academy of Sciences who are engaged in quantum computer research came here.

Facing the eager eyes of a group of people, Lu Zhou smiled, without saying anything, and led them to a multimedia projection room, while he stood in front of a whiteboard.

"...Before we start explaining, we must first clarify a basic concept. The topological properties of matter will not change due to 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 this...and then?"

"The same is true when this concept is extended to quantum mechanics...Of course, these are very basic things. What is not fundamental lies in how we use this series of properties to achieve the results we want."

As he said that, Lu Zhou turned around, picked up the electronic pen and waved it towards the whiteboard twice, the six-grid pattern seemed to grow out of the white panel, and was printed directly on the whiteboard.

Looking at the sci-fi scene in front of them, including Academician Liu, experts from the Chinese Academy of Sciences all had expressions of surprise on their faces.

Noticing 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 blackboard writing... After all, many things in physics are different from mathematics, and many things do not seem so intuitive. A convenient blackboard writing tool can at least save Time for me to get the ruler and eraser."

In fact, this thing has no special technical content, just a whiteboard with touch and display functions, plus a smart camera with motion recognition function. A long time ago, a similar thing appeared in the MIT classroom, but the function of that thing is not as rich as his, and the operability is far less flexible than his.

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

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 command, rows of uniform black dots quickly appeared on the whiteboard covered by six grids.

These black dots represent individual subatomic particles, which are moving in a circular motion with uniform speed around invisible circular orbits.

Seeing everyone in the audience staring at the whiteboard intently,

"...such quantum systems are inherently immune to decoherence and have the property of accurately executing preset algorithms."

"Having said so much, I'd better demonstrate it directly..."

As he said that, Lu Zhou waved his hand towards the door, and a drone floated over, placing a small box firmly in his hand.

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

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

I don't know what kind of medicine is sold in Lu Zhou's stomach, Academician Liu hesitated for a moment, then nodded.

"I brought it."

"Very well, then I'll give it to you."

With that said, Lu Zhou returned the small box to the drone, then signaled the drone to fly in front of Academician Liu, and put the small box on his desk.

Picking up the small box and taking a look, after opening it, Academician Liu was surprised to find that there was actually a 10-key numeric keypad and a simple display screen inside.

It's like a small calculator, except that there are no symbols for addition, subtraction, multiplication and division, and an extra confirmation button. I don't know what this thing is used for.

At this time, Lu Zhou continued to speak.

"...We all know that it takes only 0.3 seconds or less for a conventional computer to generate a 1024-bit prime number, and 0.6 seconds for two, and the multiplication operation between the two is so fast that it can be ignored."

"But if it's the other way around, and the product of two large prime numbers is taken apart, the same computer may not be able to do it in three days and three nights."

The moment the words fell, there was commotion in the classroom.

A trace of surprise, 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 gesture of invitation.

"Now you can use your computer to randomly generate two prime numbers of any size...preferably over 1024 bits, and then find their product."

"I'm sure it's easy for you."

"Finally, I hope you will input that product into this box, and soon we will be able to witness miracles."

The Adam's apple moved, and Academician Liu's trembling voice was full of excitement.

"Could it be—"

Looking at Academician Liu, who had begun to show surprise on his face, Lu Zhou didn't say anything, just nodded with a smile.

"Just try it and you'll know."

Or mixed with mixed feelings of doubt and excitement, Academician Liu used his computer to quickly generate two large prime numbers exceeding 1024 digits according to what Lu Zhou said, and input their product into this pocket calculator tirelessly.

And other experts from the Chinese Academy of Sciences, as well as Director Li, stood around him one after another, watching him continue the experiment.

After all, it is a number with more than 2,000 digits, and the input work took a long time.

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

Not the slightest lag.

As if doing a simple addition and subtraction, the product of this large prime number was quickly disassembled and divided into two prime factors.

Looking at the numbers that appeared on the screen, not only Academician Liu, but almost everyone around him made a sound of surprise.

Moment!

This problem, which would have taken days for a conventional computer, was solved in barely a second!

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

Before coming here, he originally thought that the solution to the problem of qubit entanglement collapse that Lu Zhou said was only a theoretical solution.

Unexpectedly, when he was still confused about the theory part, not only the theory, this Academician Lu even made specific samples.

It was not only the experts from the Chinese Academy of Sciences who were shocked, but also Director Li who was standing by and watching.

Shocked as to what changes this technology will bring to the world, he no longer has the time to think about it.

The only thing he knows now is one thing.

The RSA encryption rules, which have been used for at least half a century, can completely withdraw from the stage of history from today...
