"Führer, the distance has already reached 100 kilometers." Zhang Tianlin said a little hurriedly.

"Start testing." Huang Haojie commanded.

"Okay." Zhang Tianlin turned around and instructed the others, "Send a communication connection to the No. 1 quantum communicator." ”

"The connection is successful, and the No. 1 reply is received." The researcher replied excitedly.

"Go on."

The test went very well, and Zhong operated the Xingtian mecha through Luzon, into the Western Pacific, then into the South Pacific waters, and then straight to Antarctica.

It was 16,000 kilometers all the way, fortunately it was a nuclear fusion reactor, otherwise ordinary fuel would not be able to support this kind of long-distance flight, after all, it is 32,000 kilometers round trip.

It took nearly six days for the Xingtian mecha to complete the 16,000-kilometer flight.

Huang Haojie has returned to Keelung and handed over the rest of the testing work to the Quantum Chip Research Institute.

And the test results are also in line with expectations, at least Zhang Tianlin and others tested a distance of 16,000 kilometers, there is no problem.

Moreover, the advantage of quantum communication is that it can ignore the influence of the external environment, whether it is underground, in the sea, or in space, it is the same for quantum communication.

"Führer, this is the result of our test." Zhang Tianlin reported to Huang Haojie through holographic communication.

Huang Haojie flipped through the documents, and he continued to instruct: "In addition to leaving two in your research institute, the remaining three will be sent to outer space, and let them test the limit communication distance of the quantum communicator." ”

"Okay." Zhang Tianlin should be given this task.

If quantum communicators can achieve lossless communication over long distances, this technology will be a huge change for the alliance.

The interstellar colonization and development of the Human Innovation Alliance faces three major problems, the first is the speed of the spaceship, which has now been preliminarily solved, and the sub-light speed spaceship is more than enough for the internal activities of the solar system.

The second is the problem of communication, the upper limit of electromagnetic waves is the speed of light, the speed of light communication in the planet is so-so can be dealt with, but once you enter the internal communication of the star system, the communication delay problem is very serious, from Mars to the blue star back and forth it will take more than ten or twenty minutes.

This issue may not have much impact now, but if it persists for a long time, it may lead to a gap between the colony and the home planet, which can easily breed separatism.

Quantum communication is one of the ways to solve this problem.

The third problem is the human body, which is not yet able to survive in outer space for a long time, and this problem is also a big problem that restricts human exploration of outer space. The technology that this problem is for is the human body enhancement technique.

For quantum communication, the alliance attaches great importance to it, and soon arranged for the spacecraft to send three quantum communicators and three researchers into outer space through the Kaohsiung mass projector.

Kaohsiung Space Center.

Zhang Tianlin took one of the quantum communicators in the space center.

"Captain Zeng, okay, no." Zhang Tianlin asked anxiously.

"Wait a minute, the Dongfanghong base in the lunar region has not yet replied." Zeng Baojiang looked at the holographic display and replied.

"Report, the Dongfanghong base in the lunar zone is ready for testing."

Zeng Baojiang nodded to Zhang Tianlin: "Director Zhang, you can test." ”

Zhang Tianlin hurriedly instructed the staff of the research institute to start using the quantum communicator to contact the quantum communicator of the Dongfanghong base in the lunar region.

After a while, the staff entered the quantum communicator [Moon Moon, here is the blue star, please return if you receive it. ］

[Blue Star Blue Star, this is the Moon, has been received.] ］

After communicating with each other three times in a row, the staff said excitedly: "Zhang Suo, the experiment was very successful, the communication was very smooth, no delay was found, and the error definitely did not exceed 0.001 seconds." ”

Zhang Tianlin patted his hands, he was so excited, the average distance between the moon and the blue star is about 385,000 kilometers, and the one-way communication is delayed for about 1.28 seconds at a time, and it is almost three seconds back and forth.

"Try a few more times."

"Okay."

Zhang Tianlin turned to look at Zeng Baojiang, Zeng Baojiang hurriedly replied: "The Martian space station is ready, and the spacecraft is waiting for about half an hour!" ”

Soon the test of the space station in synchronous orbit with Mars was also very smooth, almost instant communication, and the small delay between the quantum communicators was actually caused by the staff.

Next is a quantum communication test with the Riturist spacecraft, which is heading towards the outer regions of the solar system, where it has just passed through Jupiter's orbit and reached a region about 640 million kilometers from Blue Star.

"Yuri, is the communication normal?" Fang Haibo asked.

"Very good, compared to the previous slow delay communication, this quantum communication is the real instant communication." Yuri can't put down the quantum communicator, and only after experiencing the experience of being able to communicate once in tens of minutes does he know how bad electromagnetic wave communication is in the interstellar era.

"Alright, let's move on."

"Hey!" Masashi Kishimoto nodded.

They are already out of the bay at this point, because the ship has reached cruising speed, and there would be no overload problems without acceleration, so they can get out of the bay.

The orbit of Saturn is about 1.35 billion kilometers away from the blue star, which means that the spacecraft is about 710 million kilometers away from the orbit of Saturn, and the spacecraft at cruising speed needs about 4 hours and 45 minutes to cross the orbit of Saturn.

As for the electromagnetic wave communication system, that speed has become extremely impressive, now it takes about 36 minutes to send radio waves back to Blue Star in one direction, and about 72 minutes to go back and forth, and when the Sun-to-Day crosses Saturn's orbit, the one-way radio wave communication time will become 75 minutes, and the round trip is 150 minutes.

Four hours and 45 minutes later, the spacecraft crossed Saturn's orbit and reached a distance of 1.35 billion kilometers from Blue Star.

"Yuri, how's the quantum communication going?"

"Captain, everything is normal, there is no exhaustion and delay."

"Go ahead, we're moving toward Uranus' orbit."

The Sun-By-Day spacecraft flew forward, this time aiming for the orbit of Uranus 2.59 billion kilometers away from Blue Star, and if quantum communication is still possible, it will continue to the orbit of Neptune (about 4.37 billion kilometers away from Blue Star).

Twenty hours later, the Sunrise crossed Neptune's orbit, and quantum communication can still be instantaneous.

On the inner edge of the Kuiper Belt, which flew to the sun, some ice material was collected from an asteroid and refilled with nuclear fuel by electrolysis of water.

It flew further into outer space again, until it was more than 136 astronomical units (about 20.4 billion kilometers) away from the blue star, and the quantum communicator showed a noticeable signal weakness.

Fang Tianbo, who was afraid of getting lost in interstellar space, immediately decided to return to the inner layer of the solar system.

However, this voyage not only tested the powerful performance of quantum communication, but also collected a large number of samples and monitoring data in the Kuiper Belt and the Oort Cloud, creating a new history for mankind.

It is also known that Voyager 1 has only flown 17.7 billion kilometers now, while the Ritzer spacecraft has flown 20.4 billion kilometres, and if it weren't for the fear of Star Trek, Riyue could have flown even farther.

And Zhang Tianlin, Zeng Baojiang and others at the Kaohsiung Space Center have been stunned by this distance, not only the communication distance, but also the flight distance of the spacecraft.

The two of them, who hadn't had a good rest for several days, were looking at each other with bloodshot eyes.

"It looks like we're going to have a big change in our communications system." Zeng Baojiang said happily that the emergence of quantum communication has greatly strengthened the communication of the Human Innovation Alliance in various jurisdictions of the solar system.

"I feel that the potential of quantum communication is still very large, and we can continue to dig deeper." Zhang Tianlin was also very happy.

Soon the news of the successful quantum communication test became known within the alliance.
