In the Imperial Capital, Imperial College London's largest and most luxurious Imperial Lecture Hall, an open class is underway.

“…… By measuring the polarization sequence of the optical quanta, the quantum key is generated, and then the key is distributed by the optical quanta, and we can establish a theoretically absolutely secure encrypted communication ...... on the ordinary information network."

"When a third party intercepts this string of optical quanta and measures it without authorization, none of its three parties can produce a valid quantum key, which leads to the inability of both parties to the information transmission and the person who intercepts the information to decrypt the file, so from this point of view, at least the security of the file is sufficient to guarantee."

“…… At present, the ultra-confidential quantum communication network is not strong in terms of anti-interference, and once intercepted by a third party, the communication will be immediately interrupted, so it cannot be used for military purposes for the time being. However, in banks and other areas where personal passwords and important administrative information need to be kept confidential, the advantages of quantum encryption can be brought into play......"

“…… Okay, this is the end of today's open class, do you have anything you would like to ask? ”

On the podium, a young professor under the age of 50 is talking to these future elites about the cutting-edge communication theory of flower growers. The audience was also full of pits and valleys, and some people even preferred to stand in the aisle rather than give up the opportunity to listen to this open class.

Whether it is for the professor's own huge reputation, or for the latest cutting-edge theories in the communication industry, it is enough to call on a large number of students to fight for the opportunity to attend lectures, and there is also news that this industry leader is likely to choose a few graduate students at this university!!

Think about it - to be a deputy to the scientists of the world's civilizations! How high does that have to be? Taking this as a starting point, after standing firmly on this platform, the sky is high and the birds can fly, and the sea is wide and the fish can swim! The foreseeable future is absolutely limitless!

So, when the professor finally stopped and waited for the students to ask questions, almost all the college students present raised their arms in the air, hoping to get a chance to ask questions, and it would be even better if they could still make a deep impression on the professor!

"Please give the microphone to the blue-clad classmate in the front row." The professor pushed his glasses and looked at the male student below who was busy taking notes without lifting his head and wearing a blue tracksuit.

"Oh? I didn't raise my hand......"

"What? Professor Pan named me? ”

A slightly hoarse voice came out of the microphone...... However, he soon realized that his words had been amplified by this very good quality microphone, and he had to stand up.

"Ah...... Sorry, thank you. ”

The student in the blue sportswear stood up helplessly, and after thanking the staff, he looked at Professor Pan on the podium and grinned: "Excuse me...... Ahem Professor Pan, what is the current bottleneck restricting the development of quantum communication? ”

"It is the long-distance transmission of light quanta, and in optical fibers, the propagation of light quanta...... attenuation in the atmosphere...... So...... Do you still have questions? ”

"No, thank you."

Professor Pan finally ended his lecture after another lecture, and the students in blue tracksuits finally breathed a sigh of relief, handed the microphone to the staff and prepared to sit down, but at this moment, his phone vibrate.

"Luckily, it shook the tune...... Who is it? The student in the blue tracksuit frowned, what a call at this time......

"Huh?"

The blue tracksuit looked at the number on the phone carefully......

"Is it really him!? He's not ......"

The blue sportswear looked up at the podium, and at this time, Professor Pan was smiling and pointed to another student who asked a question:

"Next, the female classmate in the back row who raised her hand very hard, and the one with an orange hairpin......"

"Whew...... Didn't pay attention to me, slipped away. After seeing that Professor Pan's attention was not here, the blue sportswear quickly packed up the notes he had made, clipped them under his armpits and slipped out.

"Whew...... The missing have returned? This is really a novelty......" The blue sportswear finally squeezed out of the Imperial Lecture Hall, took out his mobile phone and reconfirmed that the number dialed was indeed one of his few friends, and finally pressed the call back button.

"Dut...... Toot ......"

"Hello? Willing to answer the phone? What about giving a lecture to the girl again? A relaxed male voice teased.

"How can there be a sister in stinky dick, you are handsome and rich and sarcastic about me?" The blue tracksuit buttoned his nose and said disdainfully.

"Who's to say no? Didn't anyone say that you wouldn't get married? And who ...... that"

"Stop, stop! Something to say, nothing to do. The blue tracksuit seemed to have been caught with a sore foot, and he almost hung up the phone in anger.

"Something." The male voice on the other side of the phone groaned for a moment and said slowly, "That...... I want to get a supercomputer, how should I start? ”

"Save it yourself?" Blue Tracksuit asked.

"Hmm."

"What architecture do you want? How much power does it consume? How fast does it run? Blue Tracksuit thought for a moment and asked.

"I don't know anything about architecture or power consumption, you know...... I'm not interested in electronic devices. The voice said, "Speed, 20 Kamui should be enough, right?" ”

"Well, I'll find someone for you to ask, there should be a ready-made ...... Wrong! Wait a minute! Are you talking about the light of Sunway Taihu Lake? Lan Sportswear said something casually, but when he came back to his senses, he was startled by the voice.

"It's not April Fool's Day, is it? Are you kidding? The blue tracksuit roared into the phone, "Twenty Taihu Lake Lights!?" You're going crazy!? I don't ask anything else, I'll just ask you how much budget you have, dare to be so big? ”

"Probably...... 30 million dollars, and another 10 million in two months. The voice on the phone said calmly.

"Phew! Three thousand for ten thousand! Also the dollar!? You didn't even sell your dad...... Ah, I'm sorry, I ...... I'm not intentional. Halfway through his words, he suddenly remembered the situation of the guy opposite.

"Don't worry, Uncle Chen will definitely be fine, the country will definitely do its best to find him, you must not think about disappearing again......" Lan Sportssuit said cautiously into the microphone.

"I know he's fine." The voice on the other end of the phone was still calm, and I couldn't hear any mood swings, "You just say if you can do it, right?" ”

"Are you serious?"

"Of course!"

"This ...... Which chip are you going to use? No, what are you going to supercalculate for? Depending on the function, the hardware of the supercomputer is also different. Blue Tracksuit asked.

"That...... Self-designed. Oh yes, I'll read the performance parameters of the chip, the main frequency ...... Outside...... "The voice barabala, reading a bunch of numbers.

“…… Phew! You're a chip from Zenith Technology, right!? Blue tracksuit complained.

"Less nonsense, hurry up and help me calculate how many dollars I want!"

"The problem is not a matter of how many chips, supercomputing also involves architecture, data exchange, overall design and other issues, I am just an ordinary student, how do I know if you ask me so directly!?"

"It's really not good, you go to Lao Pan, he has a big face......"

"Then you call him! What are you looking for me for? ”

“…… It's not impossible......" The voice on the other end of the phone suddenly weakened.

"Hey, when are you coming back? Remember? You still owe me a meal......"

"Doodoo ......"

Listening to the busy tone on the phone, the corners of the blue tracksuit twitched.

"Damn Chen Zheng!!"
