Stepped into the lab.

Academician Xue glanced around a little nervously.

I was nervous partly because of curiosity, and partly because I was worried about seeing something I shouldn't have seen.

As if seeing through the concerns in his heart, Lu Zhou said in a relaxed tone as he walked towards the laboratory with him.

"Don't be so nervous, since you're a relevant person, even if you see these things, it's nothing."

It's a different story if it's the lab on the third basement level, but it doesn't matter here. Since he moved these things to the surface, it meant that even if they were seen by others, it would not be a big deal.

After hearing Lu Zhou's words, Academician Xue finally breathed a sigh of relief in his heart, and his face also returned to a calm expression, no longer restrained, and began to look at the layout of the laboratory curiously.

This is different from most of the laboratories he has seen, and it can even be said that it is more like a simple workshop than a laboratory.

Looking at the device connected to the computer that looked like a wardrobe closest to him, Academician Xue asked casually.

"What is this?"

"Laser Fusion 3D Printing System...... It is mainly used to process some metal and plastic devices that I need, after all, it is very troublesome to find a partner manufacturer to order, and I don't really want to waste time waiting. ”

Academician Xue was surprised.

"You're still going to operate this thing?"

Lu Zhou explained casually.

"In a sense, it's voice-activated...... Thanks to our AI technology. ”

Hearing this explanation, Academician Xue subconsciously opened his mouth.

Voice?

Artificial intelligence?

How is this thing voice-activated and intelligent?

He can understand automatic modeling, but how can AI understand what kind of model the user needs through a few words? Is this a problem that can be solved by pure artificial intelligence or fuzzy computing?

However, he is not an expert in this area after all, and if he doesn't understand, he has no right to speak, so he didn't dwell on this issue too much, but looked at another device that he didn't understand the purpose of.

"That'...... What about that? Pointing to the silver-white metal tube that stretched across the entire laboratory, Academician Xue continued to ask, "What is that thing for?" ”

"Multi-line single-photon channel...... That's what I'm going to show you," Walking to the middle of the metal tube, Lu Zhou picked up his gloves from the laboratory table next to him and put them on, and carefully took out a cylindrical structure covered by a titanium alloy bracket from a low-temperature inert gas protection box.

In the cross-sectional part of the cylinder, you can see a honeycomb-shaped opening, while in the central part of the cylinder, it is made up of frosted glass-like translucent vessels.

Looking at the puzzling things that popped up one after another, Academician Xue felt like a primitive person.

Although he didn't want to say any more about these three words, he really couldn't understand it, and finally he opened his mouth angrily.

"What is this?"

"A three-dimensional cavity with a multi-mode structure, the main material is an alloy composed of ytterbium and molybdenum and other materials, which can satisfy all our fantasies about the quantum world......" It seemed that this sentence was a little inaccurate, Lu Zhou thought for a moment, and then corrected it, "At least the fantasy at this stage." ”

Academician Xue opened his mouth slightly dumbly.

What was in front of him was a little more than he expected.

His instinct told him that what was in front of him might be more powerful than he had imagined, but for a moment he couldn't say exactly where this almost magical contagion came from.

That......

For a moment, he even forgot what he had come here for.

"I know you have a lot of questions you want to ask, and I'll talk to you about your confusion later."

As if seeing through the surprise and curiosity on the old man's face, Lu Zhouxiang nodded slightly, and then turned around and carefully placed the mysterious cylinder on the groove where the opening almost matched 100%.

Watching the cylinder descend at a constant speed under the traction of gravity, Lu Zhou took two steps back and stood next to a computer, with a satisfied smile on his face.

"It was just perfect!"

Academician Xue: "...... I do not quite understand. ”

"In short, it's a quantum entanglement amplifier that you can think of as a kind of magnifying glass. But it's not light that it enhances, it's something more microscopic than light. ”

The expression on Academician Xue's face was slightly moved, and a crazy possibility came to his mind.

“…… Single photon? ”

"Correct...... But not exactly, to be precise, entangled photon pairs. ”

As he spoke, Lu Zhou snapped his fingers, as if he had heard some kind of command, and the signal light on the chassis behind him lit up one after another, and the ends of the silver-white metal pipe in front of him also emitted a slight hum.

Not realizing how shocking the scene in front of him was to the person next to him, Lu Zhou continued to explain.

“…… By placing the three-dimensional cavity of this multimodal structure in a special magnetic field, the free ytterbium atoms in the alloy enter an extremely insensitive state, which isolates them from interference in the environment, traps the photons at the entry port, synchronizes them, and then passes the entangled state to the next repeater through a new single-photon emitter, and repeats the process. ”

Academician Xue's eyes widened for a moment.

"This, is this!"

"It seems that you have already guessed," Lu Zhou nodded with a smile, "Quantum communication." ”

As he spoke, the preparation for the experiment was completed.

64 pairs of optical quanta are emitted from port A, amplified by the repeater while passing through the quantum repeater in the middle of the pipe, and continue to transmit to the next channel, and finally received by the receiver at port B.

Looking at the numbers fed back on the screen, the corners of Lu Zhou's mouth pulled up a smile.

64 photon pairs!

Receive them all!

There is no doubt that his experiment has been successful!

Stunned as he watched everything that happened in front of him, Academician Xue, who was standing in the center of the laboratory, gradually recovered from his surprise until Lu Zhou included the data in the database.

"It's over?"

Lu Zhou, who was standing in front of the computer, replied casually.

"It's over, the experiment was a success."

Academician Xue: "...... What are you showing me this for? ”

There is no doubt that what he saw in front of him was probably more confidential than the quantum encryption algorithm.

He really couldn't understand why Lu Zhou was showing these things to himself.

"Because it's not perfect, I've only solved part of the problem, but there is still a part of the problem that hasn't been solved, and this part is not what I'm good at......" Lu Zhou glanced at the wall clock on the wall, and suddenly smiled and said, "Now that the experiment is over, we might as well talk in another place." ”

As he spoke, Lu Zhou reached out and knocked down a few buttons on the keyboard, and after waiting for the device to turn off completely, he pressed the power button next to the case.

After doing these things, he turned his gaze back to Academician Xue and made an invitation.

"Go to my office."

"We can have something to drink and talk about these interesting questions."
