Gu Song, a down-to-earth young man, woke up early in the morning and finished breakfast, and arrived at Xie Yinran's house.

"Eh, Komatsu, have you eaten it?" Wang Yunlu opened the door, a little surprised in her heart.

Gu Song smiled and said, "After eating, isn't Haoran going back to Yanjing?" I'll pick him up and go with him." ”

"Why don't you say it in advance, this guy is still sleeping. Wang Yunlu asked him to enter, and shouted inside: "Haoran, get up! Brother Gu Song is here to take you back to Yanjing." ”

It was Xie Hongxin who came out first, and he came over and asked, "Why didn't you see the refreshing axe lake in the news yesterday?"

Gu Song said with a smile: "Uncle Xie, how could such a big matter be broadcast on the news before it has been decided? ”

Xie Hongxin let go of his worries and smiled.

At this time, Xie Haoran also came out wearing a vest and pants, and he asked excitedly: "Brother Song, did you drink with Elder Bao last night?"

Xie Hongxin raised his hand and wanted to shout, but Xie Haoran hurriedly dodged.

"Elder Bao inspected the Shenaxe Lake yesterday afternoon and left, and last night he was drinking with the leaders of the city. You hurry up and brush your teeth and wash your face and finish breakfast, and let's go back to Yanjing together. ”

Xie Haoran stood up loudly: "Order!"

Gu Song laughed happily, and Wang Yunlu asked helplessly, "Really eat?"

"I really ate it, otherwise my mother would say that I went home for nothing and didn't eat a bowl of noodles. ”

Wang Yunlu heard that he was telling the truth, and said with a smile: "Your mother often talks about you like this, and as soon as you come back, you drink and socialize outside." ”

With that, she went back to the kitchen.

Gu Song glanced at the inner room, pretending to ask Xie Hongxin casually, "Where is Yin Ran?"

"Get up, you're reviewing, right?"

Xie Hongxin roared loudly, and heard Xie Yinran say inside: "After I finish painting this painting, you eat first!"

Gu Song smiled at Xie Hongxin, Xie Haoran had already washed it at the speed of light, and ran over to gossip excitedly.

"Brother Song, what is Elder Bao like in private?"

“…… That's it. ”

"Tell me! It's definitely not the same as on TV, which is always very kind. Have you ever seen him lose his temper?

Xie Hongxin couldn't listen to it anymore, and a slap on his head was firmly called: "What nonsense?"

Xie Haoran covered his head and said aggrievedly: "Dad, I eat with my brain and hands now, you beat me stupid, what should I do if I react slowly during the game?"

"Then you don't know how to check?"

Gu Song hurriedly persuaded and said to Xie Haoran: "You are indeed too excited, save this excitement for the arena." ”

Wang Yunlu took out the boiled shredded beans, and Da Xie and Xiao Xie went to eat them. Wang Yunlu asked, "Xiao Song, do you want to eat another small bowl?"

"Okay. Gu Song smiled obediently, "Auntie's shredded beans are delicious." ”

Wang Yunlu happily filled him a small bowl, Gu Song was eating and chatting with them, and Xie Yinran came out of the back room.

She only shouted "Brother Gu Song", and sat down at the table to eat with her head bowed.

Wang Yunlu saw it in her eyes, this girl didn't look so unkind to Gu Song before, she was talking and laughing.

She observed carefully, but Gu Song, as usual, was just chatting with Lao Xie and Haoran.

After breakfast, Wang Yunlu took out Haoran's luggage, and before the two left, Gu Songcai looked at Yin Ran seriously with a smile and said, "Yin Ran, take the college entrance examination well, and you will go to Yanjing to go to university in the second half of the year." ”

Xie Yinran only said "um".

Downstairs, Guan Li waited there, and picked up the two of them in the car.

Wang Yunlu turned her head and saw that Yin Ran had already turned around and went to her room.

She was also a little puzzled, could she be wrong?

How did Wang Yunlu know that Xie Yinran was muttering in her heart.

Did he come to see him, or did he come to pick up his brother and go back to Yanjing together?

Did his last glance mean to "look" at himself?

Where did the first four postcards come from, and what are they written?

But it's hard to ask now, and I'm embarrassed to ask.

……

After returning to Yanjing, Gu Song's first stop was to go back to Xiangshan Villa.

After a few days, the underground laboratory changed a little more.

At this stage, the underground laboratory is just round by round, iterating equipment.

After iterating on the equipment with higher measurement accuracy, it is possible to manufacture more precise processing equipment in this small laboratory.

These are not in a hurry, after all, it has only been more than 3 months since the system was upgraded.

What I have to worry about now is the first wave of flint aerospace's basic project: the stars.

Externally, this is a VSAT project, like the Iridium project, which uses satellites to form a network to achieve global satellite communications.

But what is the use of such a VSAT satellite network for Project Flinth?

Externally, it can be said to be a little more commercial, just like Musk's usual routine.

But in fact, after the completion of this wave of equipment updates and iterations in the laboratory, the satellites that will be used in the Stellar Project are naturally not ordinary satellites.

The first step of the Flint Project is to build an absolutely confidential quantum communication network!

In the future, so many things will need to be transmitted between heaven and earth, how can we not keep it confidential?

What other way of secrecy is there now, more reliable than quantum communication?

In fact, there is some progress in the research of quantum communication.

Jian Yushu has been insisting on the strategic intelligence collection that Gu Song has been doing, so that Gu Song is very clear about the cutting-edge research trends that can be learned at least through open channels.

At present, the progress of research has only reached quantum cryptography communication, and the quantum teleportation that can truly achieve ultra-distance communication and undisturbed quantum teleportation is still in the experimental stage.

Quantum teleportation is very mysterious, putting a pair of photons out of a quantum entanglement state, one here and the other elsewhere. As soon as one of them changes, the other changes at the same time.

Regardless of distance, changes at the same time, and cannot be deciphered.

Without this thing, even if the speed of light was used to transmit messages, at a location a few light-years away, communication would be almost completely finished.

In "Interstellar", Cooper watched some videos from Earth and watched his children grow up from childhood to adulthood, get married and have children.

In "The Voice of the Stars", it is a very vivid description of the emotional stimulation brought by this ultra-long-distance communication.

Therefore, if Gu Song wants to successfully complete the flintstone plan, the first problem to solve is to build his own communication network.

Of course, this communication network is not only a satellite, but also includes various transmitting and receiving systems on the ground.

Before that, of course, he had to ...... first A considerable number of entangled quanta are prepared.

This is a special way to use spontaneous parameters to spin the ring to generate entangled photon pairs...... It's kind of like a cat scratching the light.

Gu Song, who is now playing quantum in a closed underground laboratory, has not become Schrödinger's cat?
