C868 Quantum Communication

"You guys wait for a few more days. I'll try and see if I can develop a type of intergalactic Communication Talisman. I'll let you guys carry it with you so that we can contact each other at any time. Otherwise, I won't feel at ease scattering you guys into the boundless space. " Yun Fei said.

"Interstellar Communication Talisman? How is that possible?" Even though it was because of the baptism of the Telekinesis, Yue Zhixing, who had already idolized Yun Fei, could not help but cry out involuntarily.

"Old Yue, you have a lot of experience and knowledge. Do you have the kind of Talisman that can be used to cross the galaxy?" Yun Fei asked.

"I lost my composure just now. Please forgive me, young master." Yue Zhixing cupped his hands in apology and continued, "I only know one kind of Talisman that can be used to cross the galaxy, and that is the teleportation Talisman. However, on the other side of this teleportation Talisman, it must be a teleportation formation that far exceeds the effect of ordinary teleportation. It must be specially set up. Moreover, this kind of teleportation Talisman is a one-time use one. "

Yun Fei nodded his head. He had seen one before. After killing Prince Zhong Yuan, there was a so-called teleportation Talisman left behind by him, and it was even triggered on the spot. It was a waste.

According to the principle of the teleportation Talisman, one end of the Communication Talisman still needed a large-scale communication array. Furthermore, the Talisman was a one-time use one, so it was obviously not suitable.

"Young master, to communicate in the galaxy, first we need to have the Space Array to open a passageway. This is impossible to use the Talisman to achieve. The Talisman can't withstand it, and it can't store such a huge amount of energy. It's really too difficult to refine a Communication Talisman that can cross the galaxy. " Yue Zhixing said.

"Looks like I have to think of another way." Yun Fei muttered to himself and fell into deep thought.

There was a technology that could ignore the distance of space, and that was quantum communication.

Unfortunately, on December 21st, 2012, when Yun Fei was taken away from Earth by the mysterious Light Ball, the research on quantum communication on Earth was still at a beginner level. It had yet to realize the true meaning of quantum communication.

Before this, in the Peking University Library, Yun Fei had only read a few books on quantum technology: Richard. Defiman's Physics at the edge of Reason, Quantum Mechanics by Griffith, and Quantum Universe by Brian Cox and Jeff Fox, as well as some research documents accumulated over ten years.

The concept of quantum communication was proposed by American scientist Bennett in 1993. In the same year, six scientists from different countries proposed a method to combine classical and quantum. Come! A plan to achieve quantum stealth teleportation.

After that... In 1997, Pan Jianwei, the Chinese scientist, worked together with the Dutch scientist, Bomest, and the others to achieve the first remote transmission of an unknown quantum state, but this transmission could not carry any information.

2012 was also the year when Yun Fei left Earth. China's scientist Pan Jianwei and the others successfully achieved the first success of a hundred kilometers of free space quantum invisible transmission and entanglement distribution internationally for the first time.

The core research documents of these technologies were all confidential, but some of the principles and technologies used in them were publicly published.

Yun Fei also learned about the research results of Pan Jianwei and the others through the International Augmented Academic Magazine Nature on August 9th, 2012.

Quantum communication had always been covered with a mysterious veil, and it was also the cutting-edge technology.

The core of this technology was to use quantum entanglement to transmit information.

The so-called quantum entanglement was based on quantum theory, in the microscopic world. There was always such a pair of particles, no matter how far the distance between these two particles was. One. The change of the particle would affect the phenomenon of the other particle. This phenomenon was also known by Einstein as "strange interaction."

When communicating, there were two particles with entangled states in the hands of both parties. One of the particles had a change in the quantum state, and the other party's quantum state would immediately change.

This change ignored spatial distance. Theoretically speaking, it was not a problem to cross the galaxy, and it was in real time. The speed of transmission had nothing to do with distance, so naturally, it was not limited by the speed of light.

Also, according to quantum theory, any observation and interference would immediately change the quantum state at that time, causing it to collapse.

Thus, the information obtained by the thief due to interference was already destroyed, and not the original information.

This caused the content of the quantum communication to be kept secret, and it could not be stolen by any technical means.

The two major characteristics of quantum communication showed its advanced nature: ultra-long distance, real-time speed, and confidentiality and safety.

After so many years, it was unknown whether or not the China scientists led by Pan Jianwei had achieved true quantum communication on Earth.

Yun Fei's thoughts drifted to the beautiful planet in the distance - Earth. He thought of the China nation that was flourishing day by day and gradually leading the global trend. He also thought of his grandfather who had painstakingly raised him up.

Everyone didn't disturb Yun Fei who was deep in thought. Yun Fei was also letting go of his thoughts.

After sighing for a long time, Yun Fei returned to reality. He still had to think of ways to use quantum technology to make Communication Talisman.

In order to achieve quantum communication, the first thing to do was to find a pair of particles in quantum entanglement. Then, he would refine these pairs of particles into two Talisman respectively.

Pan Jianwei and the others' experiments and research were all using photons with quantum states. In this world, there were no high-tech instruments, and they were unable to obtain the entangled photons.

Regarding quantum entanglement, Yun Fei, who had cultivated the Limitless Chaos Spell for a long time, suddenly had a guess. Everything in the world had yin and yang. This pair of entangled particles, was it the yin and yang nature of a particle?

Perhaps these two particles were two sides of the same thing, one yin and one yang.

This could also be explained. No matter how far away they were from each other, these two particles could always affect each other, displaying a phenomenon called "strange interaction" by Einstein.

Because these two particles, you are me, and I am you. It's just a Yin and Yang aspect of an object.

And this kind of conjecture was surprisingly the same as the ancient Chinese Yin and Yang theory that originated from the Limitless Chaos Spell.

There were theories and conjectures, but it was hard to realize them.

First of all, how to find the same matter of Yin and Yang particles? Second, how could one separate and store them after finding them? Finally, he had to separate these yin and yang particles. He had to convert the information that the Communication Talisman had transformed into and the changes in the particle arrangement to complete the collection and distribution of the information. To achieve communication.

The technology of ordinary Communication Talisman was mature, and Yun Fei also understood it. The various array modules, as well as the interfaces and lines of the array, were extremely familiar.

If he could deconstruct those yin and yang particles, Yun Fei was confident that he could embed them into this ordinary communication array.

As long as there was an additional information conversion array between the ordinary communication array and the embedded yin and yang ions, when it was launched, the information that would be transmitted would change into the pattern of the particles. When it was received, the law of change of the particles would be converted into information that ordinary Talisman could recognize.
