It's reasonable for me to have a two-way foil for a second-level civilization, right?

algorithm.

He needs to redesign a set of algorithms that belong to long-distance communication.

Simply put, he needs to establish a system for the various state changes of photons, just like Morse code.

Only in this way can humans transmit real-time data by changing the state of one or several photons.

"Mr. Tang, I entrust this difficult task to you."

After the experiment was successful, Lu Yongchang was in a good mood, and half-jokingly said to Tang Wenshan: "Such an important project, please don't lose the chain!"

Tang Wenshan naturally heard the irony in Lu Yongchang's words. He first glanced at the smiling Lu Yongchang in front of him, and then laughed and said, "Don't worry."

"With zero help, if I can't do this task well, I, as an academician, can be regarded as useless!"

Lu Yongchang smiled and nodded.

That's right.

With the existence of strong artificial intelligence like zero, the algorithm problem has become the easiest point to break through in all scientific research projects.

He turned his head and looked at the two huge equipment, the smile on his face gradually faded, and there was a little dissatisfaction in his eyes, and he muttered to himself: "It's a pity."

"Ok?"

"It's a pity?" Tang Wenshan was stunned, and quickly reached out to pick his ears, for fear that he heard it wrong, "What a pity?"

"Didn't the experiment go well?"

Lu Yongchang shook his head slowly: "These two things are too big."

"Combined with other functional components, it is estimated that the volume will increase several times."

"This severely limits its application scenarios." Lu Yongchang frowned and estimated, "Currently only Luanniao series starships can carry this kind of long-distance communication equipment."

"This will probably have a relatively large impact on future interstellar wars."

"Next, I may need to reduce this device, but... this work will be more difficult."

Facing Lu Yongchang's troubles, Tang Wenshan waved his hands nonchalantly and said, "It's all small problems."

"With the current scale of human civilization, it is enough to install ultra-distance communication equipment on the Luanniao starship."

"As for the lower-level starships, you can use the Luanniao platform to transmit information."

"Millisecond-level delays are not a big problem for humans today."

"What's more, we can reduce the delay problem as much as possible by increasing the number of Luanniao starships."

What Tang Wenshan said casually made Lu Yongchang's eyes shine.

Makes sense!

As expected of a big guy in communication, just a few words solved his troubles!

At that time, only needing to use the Luanniao Starship and the Xuannv Starship together will be enough to solve this difficulty!

He would like to call it the "Step-Tank Synergy" of the interstellar era!

"There is one more problem." Lu Yongchang's eyes moved slightly, and he continued to speak, "After these few days of experiments, I found a problem."

"Strictly speaking, quantum long-distance communication technology is not real long-distance communication technology."

Chapter 183 New Combat Squad

"What do you mean?"

Tang Wenshan frowned tightly: "Isn't this ultra-distance communication?"

"Quantum action at a distance has been verified by experiments..."

Lu Yongchang shook his head meaningfully, interrupting Tang Wenshan's words.

"No, this kind of long-distance communication is just a trick."

"Mr. Tang, haven't you noticed that in our long-distance communication, each device can only communicate with the corresponding device?"

"A pair of entangled photons can only create a pair of long-distance communication machines."

"And this pair of machines can only accept messages from the other party."

"Normal communication equipment, but there has never been a one-to-one talk."

Tang Wenshan's complexion changed slightly.

Under the shock of joy brought by the success of the experiment, he subconsciously ignored such an important point.

"Moreover, we must first send the corresponding terminal to the destination before we can conduct long-distance communication with the target location." Lu Yongchang continued, "This means that if we want to communicate with other civilizations, we still have to rely on Electromagnetic waves are an extremely "slow" means of communication."

"Unless we send a quantum communication terminal there first."

Tang Wenshan frowned even deeper.

He pondered for a moment, then said in a low voice: "But...but this is the disadvantage of quantum long-distance communication, and we have no way to avoid it."

Lu Yongchang didn't speak, but nodded silently.

Is there really no way to avoid it?

Thinking that according to the division of the technology tree system, they are still in the lowest level of civilization, Lu Yongchang's eyes revealed a bit of undetectable bitterness.

Perhaps, it's just because the technological level of human beings is too low.

……

half a month later.

Qinghai-Tibet Plateau, People's Alliance Starship Base.

"Andrew?!"

Hong Fan's iconic voice sounded in the base: "Why are you here?!"

Seeing the former savior, a bright smile suddenly appeared on Andrew's face.

He laughed and walked quickly to Hong Fan, stretched out his hand and patted Hong Fan's shoulder vigorously, and greeted Hong Fan in fluent Chinese.

"Brother Fan, have you eaten yet?"

Hong Fan: "...???"

Faced with such a down-to-earth question, Hong Fan replied a little uncomfortable: "Eat, eat."

"Oh no, haven't you entered hibernation? Where are your teammates?" Hong Fan raised his question again.

Reasonably speaking, ordinary people should be on their way to the Kuiper belt by now!

Suddenly, a possibility flashed in Hong Fan's mind.

"Have you not……"

Andrew nodded triumphantly: "I have passed the training and am now a regular starship pilot."

"Also, Brother Fan, the higher-ups said that we should form a team with you."

"Wait, wait." Hong Fan lost his mind for a while, "You guys?"

"Also, I remember that you said you were going to live the life of ordinary people? What's going on?!"

Andrew laughed loudly and put his arms around Hong Fan's shoulders: "Brother Fan, people can change!"

"After going to Mars, we all couldn't adapt to the ordinary life on earth."

"What's more, in the face of such a big crisis in the future, we also want to protect ourselves and our families, so..."

Speaking of this, Andrew shrugged and said: "The three of us discussed it, hit it off, and applied for the Starship Pilot Training Course of the People's Federation."

"Don't you say I almost forgot!" Hong Fan's eyes moved, and he asked quickly, "What happened on Mars, is your family okay?"

The smile on Andrew's face grew stronger.

He waved his hand lightly and said, "It's okay!"

"After the People's Federation was established, we immediately took them over."

"Now, I guess they should be near Mars, right?"

"In a few years, I plan to wake them up myself!"

Hong Fan breathed a sigh of relief, and a smile appeared on his face.

Such an ending is really good.

Just when Hong Fan was about to continue asking Andrew about the formation of a new team, a familiar voice came from the side.

"Andrew, why did you come here?"

"We've been looking for you for a long time, hurry up..."

Before Hong Fan could react, Andrew greeted the people with a smile: "Bruno, Joey, look who I met!"

"...Hong Fan?!"

"Fuck! Brother Fan!"

Two standard Chinese tones followed.

Seeing the two people rushing towards him, the corner of Hong Fan's mouth twitched slightly.

There is one thing to say, the culture of Xia Kingdom has been completely understood by them.

After exchanging pleasantries, Hong Fan suppressed the smile on his face and asked softly.

"Andrew, what exactly do you mean by joining our group?"

Andrew shrugged, with a look of confusion on his face.

"I'm not very clear either, that's what we've been notified about."

"According to the notice, we should still have tasks to perform."

"Didn't you get the notice?"

There was some doubt in Hong Fan's eyes, and he shook his head slowly.

"never mind!"

He shook his head nonchalantly: "I guess the higher-ups haven't had time yet!"

"Let's go, let's take you to the dormitory of our team."

"Let me tell you, you are blessed to join our team."

"We are a veteran team after all, the environment of this dormitory is nothing to say!"

"I won't brag with you, it's definitely the best dormitory in the base!"

……

"White team, Wanyi, look who's coming!"

Hong Fan pushed open the door of the dormitory and shouted loudly.

But when he saw the middle-aged man standing in the middle of the dormitory, his voice suddenly shrunk several times.

"...Officer Qi, you are here too."

Seeing the two teammates obediently standing aside, Hong Fan turned bitter, and walked into the dormitory dejectedly.

As for the three behind him, they stood at the door in a daze, not knowing what to do.

"Okay, don't pretend to be wronged." Looking at Hong Fan's drooping head, Chief Qi said angrily, "I don't know what you Hong Fan look like?"

"And those three outside, come in, this time I came here for your business."

Hearing this, Hong Fan breathed a sigh of relief, then elbowed Bai Yixuan beside him, and pouted towards the door.

Bai Yixuan and Xia Wanyi were obviously stunned when they saw the three Andrews walking into the room.

"You should be considered old friends, so I won't introduce more."

Without giving the six people any time to think, Chief Qi said directly: "From now on, the six of you will form a combat team and be responsible for driving the Luanniao I starship."

"The task is simple."

"You need to cooperate with Professor Lu to complete an experiment. The specific experimental content will be explained to you by Professor Lu."

"All you have to do is cooperate unconditionally."
