in the universe.
Zheng Yang, who had just said goodbye to his son, felt a little lost. He lay on the sofa of the spaceship and looked at the bright ceiling lamp, but it would not hurt his eyes to look directly at it.
Qing Feng sat on the sofa opposite him.
Holding a mobile phone, I don’t know what I’m talking about.
The signal receiver and transmitter configured on this spacecraft are relatively advanced and the signal is relatively good.
It's just that the universe is very large, and the transmission of signals will inevitably be slow.
This is the disadvantage of still using electromagnetic signals to communicate.
More advanced information exchange technology.
It's quantum communication.
Quantum communication is a new communication method that uses quantum superposition states and entanglement effects to transmit information. Based on the three principles of uncertainty, measurement collapse and non-cloning in quantum mechanics, it provides an absolute security guarantee that cannot be eavesdropped or computationally cracked.
It is mainly divided into two types: quantum teleportation and quantum key distribution.
Quantum teleportation is based on the joint measurement of quantum entanglement pair distribution and Bell states to achieve quantum state information transmission. The measurement and determination of quantum state information still requires the assistance of existing communication technology.
In Zheng Yang's previous life, key technologies such as preparation, distribution and measurement of entanglement in quantum teleportation had not yet been broken, and they only remained in theory and formula.
But in this world, it is said that 80% of the required key technologies have been cracked.
Quantum key distribution, also known as quantum cryptography.
The transmission measurement of quantum superposition states is used to achieve secure quantum key sharing between communicating parties, and then through a one-time pad symmetric encryption system.
That is, both communicating parties use a password of the same length as the plain text to perform bit-by-bit encryption and decryption operations to achieve unconditionally and absolutely secure confidential communication. (Plain text: refers to unencrypted text or strings that can be understood by ordinary people, and is a cryptographic term)
I believe that quantum communication will appear soon.
in short.
Quantum propagation is very rapid and cannot be hijacked.
Although humans have not yet broken through quantum communication, Zheng Yang believes that after learning about it,
Quantum communication, which can only be thought of in 2021, will usher in the world of Titan soon.
After all, Zheng Yang guessed that Xu Gou Yang's information upgrade in 2742 should be through quantum communication technology.
Otherwise, there should be no other communication technology that can transmit such a large capacity within a day or two and perform real-time updates over long distances...
Every major update in scientific research technology will lead to the improvement of other technologies.
In other words, within ten years at most, the world of Titan will usher in a technological explosion.
I don’t know if it will have any impact on the Titan mecha...
Inside the spaceship.
Ceiling lights cast a lazy yellow glow.
Zheng Yang looked at the ceiling, his thoughts gradually diverging.
Opposite him, Qing Feng was staring at his phone intently, as if waiting for a reply.
Suddenly, Qing Feng seemed to have thought of something.
A sudden slap on the thigh.
"correct!"
Zheng Yang was startled by this sudden voice.
"Holy crap! Why are you yelling so loud all of a sudden?"
Looking up,
Qing Feng had already stood up and walked to Zheng Yang, patting him to signal him to stand up.
"You haven't brought your suitcase yet."
Zheng Yang: "......?"
What are you talking about?
I don’t have any luggage, so why do I need a suitcase? ?
Zheng Yang asked the question in his mind.
It's a pity that this kid Qing Feng is pretending.
"You will know when the time comes. I feel your words..."
You have to consider that this guy is a murderer and came to the university to do mental health work.
Qing Feng had an idea in his mind.
Come on, you follow me.
Zheng Yang followed Qing Feng all the way to the grocery room at the rear of the spacecraft.
Qingfeng asked Zheng Yang to wait outside the grocery room while he went inside.
Close the door.
Zheng Yang, who was having nothing to do, suddenly heard a "dinging, clanking" sound coming from the grocery room.
Very loud sound.
Zheng Yang couldn't help but feel a little curious.
After a while.
The door of the grocery room was opened, and a disgraced Qing Feng walked out holding a big guy.
Throwing it on the ground, he kicked the door of the grocery room back and closed it.
This is a large rectangle that is taller than Zheng Yang and is wrapped in linen.
It should be linen...
Qingfeng washed the dust off his face and came back from the bathroom.
Lifting the sackcloth sharply.
Revealed a......
suitcase?
Zheng Yang: "???"
Then, Zheng Yang suddenly realized something, and his eyes suddenly lit up.
"Could it be that this suitcase contains a newly developed micro-gun by the resistance?"
Qingfeng: "NO."
"Is that a newly developed hidden weapon called grenade and dart?"
Qingfeng: "NO."
"Is that the Pilot's equipment, or is it a core modification?"
Qing Feng was too lazy to respond.
Just click twice on the suitcase, and then a three-layer holographic blue ring divided into upper, middle and lower pops up.
Qing Feng clicked on the holographic ring, and then the three blue rings were retracted into a diamond-shaped blue block on the surface of the suitcase.
Subsequently.
The suitcase was suddenly opened by Qing Feng.
Zheng Yang looked at it with shining eyes.
I saw it in the suitcase......
Nothing.
It just looks like the space is unusually large.
Zheng Yang: ".........? Are you kidding me?"
"You're so old-fashioned, you just want to show off a large-capacity suitcase to me?"
Qing Feng shook his head, closed the suitcase and moved it forward.
The suitcase slid in front of Zheng Yang.
"Send it to you, take it with you when you enter college later."
Zheng Yang scratched his head: "What kind of university has such a weird rule about bringing an empty suitcase?"
This time Qingfeng explained a few words.
"The university I found for you is called the University of Etiquette. People should follow the rules of the mirror and reciprocate with courtesy."
Zheng Yang complained: "So because of the homophonic pronunciation, it is stipulated that you must bring an empty suitcase?"
Qing Feng smiled: "It's not because of this, it's okay."
"Just take it with you. You'll understand later."
Although Zheng Yang had a black question mark on his face, he still returned to the front hall of the spacecraft with his suitcase.
It can be seen that Qingfeng wants Zheng Yang to understand the meaning of this suitcase by himself.
Simply, Zheng Yang started studying this suitcase.
.....................
7 hours later.
On a planet of blue, yellow, cyanosis and purple.
A large parking lot.
The spaceship landed with billowing air waves.
Zheng Yang sat on the suitcase and slid down the stepless slope steps lowered by the spacecraft.
The skating is quite skillful.
Zheng Yang actually controlled the suitcase and made a sharp turn.
Stopped.
After seven hours of boring research by Zheng Yang, he discovered that this suitcase...
It's just an ordinary suitcase with a hologram.
The doubts in my heart are getting bigger and bigger.
Qing Feng stepped off the spacecraft.
Take Zheng Yang out of the airport.
As he walked, he said: "You're in luck, tomorrow is the day when school starts."
Zheng Yang looked at the date.
【June 30, 2731】
"What a coincidence?"
"Yes, I have arranged a hotel for you for the day, and a text message to salute you should be sent to your mobile phone."
"I remember there was a map. It doesn't matter whether I have it or not. You can just take a taxi and salute when the time comes."
“The salute is in this city.”
While talking, Qing Feng sent Zheng Yang into the taxi.
"I still have something to do, you can figure it out by yourself~"
Then he went to the front door and shouted to the driver: "Master, go to the Li Nong Hotel."
After saying that, Qing Feng walked along the street gracefully.
only.
One of them walked and the other took a car.
Go in the opposite direction.
but.
All have the same goal.
That is.
Fuck you IMC!
