The technological empire begins with polymer materials

After Gao Yuan left the system space, he immediately asked his secretary Chu Luoluo to summon relevant people to the conference room to prepare for the assignment of quantum communication research and development tasks.

Everyone was already not surprised by the boss's sudden summons.

In the eyes of most people, Gao Yuan should be that kind of scientific and technological commander who is rare in the world. He usually likes to be bored in the office and think about the direction of science. Once he has an epiphany, he summons elites from all parties to carry out the project according to his own ideas. In-depth research.

It’s just that the number of plateau epiphanies seems a bit too much, just like being kissed by the goddess of luck...

In short, under the guidance of Gao Yuan's magic stick style, scientific research finally has a correct direction and is always moving forward rapidly on the right path.

If the path is right, the efficiency will be high. In addition, Gao Yuan knew the answer from the beginning. As a result, China's technological level has advanced by leaps and bounds in just a few years, sweeping the world.

Soon after, a group of China's top experts gathered in the conference room. Their research fields include optical communication, quantum communication, space transmission, gravitational wave detection, astral physics, etc.

As we all know, as early as August 16, 2016, China launched the first quantum communication satellite in human history, Mozi.

Although from a technical point of view, the Mozi is not mature, it at least shows that China has been leading the world in research in the field of quantum communication. The team headed by Pan Jianwei is currently the strongest quantum communication research team on the planet.

At this moment, Academician Pan was sitting at the bottom of the plateau, with a big mouth and wide eyes, full of shock and confusion.

"Transdimensional communication?"

Academician Pan muttered and swallowed a mouthful of spit. Assuming that it was not Gao Yuan who proposed such an unrealistic research direction, but someone else, Academician Pan might have spit on the other person's face.

So damn whimsical!

What the hell is hyperspace communication?

Just do Macross!

Simply put, hyperspace communication refers to the data link between two points, which is not bound by time and space.

One person is in the Ming Dynasty and the other is in the Yuan Dynasty, but as long as they both have a hyperspace communication device, they can talk to each other instantly.

People in the Ming Dynasty said, have you eaten?

People in the Yuan Dynasty said, "I haven't eaten yet."

People in the Ming Dynasty said, if you don’t have anything to eat, go home and eat.

Isn't this his nonsense?

In comparison, hyperspace communication seems to have some theoretical basis.

One person is on the earth and the other is on an unknown planet in the constellation Pegasus. They use a hyperspace communication device to greet each other's mother cordially. Both parties are very happy. This scene seems acceptable, at least not as unbelievable as communication across time.

Gazing across the bewildered crowd, Gao Yuan talked eloquently and introduced his idea of ​​super-dimensional communication.

Everyone suddenly realized that it turned out that the instant messaging tool was developed based on the quantum entanglement theory. In this case, it seemed to be somewhat interesting...

Bohr once said that if you are not shocked by quantum mechanics to the point of collapse of your outlook and pain, it means you do not understand quantum mechanics at all.

This shows the subversive nature of quantum mechanics. It is no exaggeration to say that quantum mechanics was born to subvert logic.

Everyone nodded slightly, feeling that if it was quantum communication through time and space, it seemed to be somewhat reliable.

But the problem comes again. The scientific community generally predicts that due to its special nature, quantum entanglement cannot be applied in the field of instant messaging...

It is very difficult to understand quantum entanglement. Academician Pan Jianwei, the number one expert in the field of quantum communication in China, once said that if one day I can understand the true meaning of quantum entanglement, I can die immediately and die extremely hard. Rejoiced.

Perhaps this is the modern version of the idea that if you hear the truth in the morning, you will die in the evening. This is true even for big-name academicians, let alone ordinary people.

For most people, quantum entanglement can actually be understood this way.

One day you were on a business trip, and suddenly your heart tightened for no reason. You thought of your girlfriend, and a touch of sadness flashed through your mind.

At the same time, thousands of miles away, your girlfriend is riding on another man, and her heart is tight, but she looks around and remembers that her boyfriend is on a business trip, so she continues to play unscrupulously.

The moment when you and your cheating girlfriend feel tense at the same time, it is the so-called quantum entanglement phenomenon.

This is not metaphysics, but real science. It is just too subversive to accept.

Academician Pan listened patiently to Gao Yuan's introduction and thought deeply at the same time. After a long time, he finally couldn't bear it anymore and said with a frown: "The mathematician Shannon once said that information is used to eliminate the existence of random uncertainty."

"Quantum entanglement is like two coins in a box. The states of the two coins are random. Then before opening the box, there will be four possibilities inside the box."

"Now we assume that electrons are similar to coins and have two states, upspin and downspin. There are two electrons in a box. The states of these two electrons are also random. Then before opening the box and observing, the electrons in the box also have four states. possibility."

"But the special thing about electrons is that when two electrons are close enough, they will release a photon, and at the same time the two electrons enter an entangled state. At this time, the electrons do not have four possibilities, but become two. Possibly, that is, the states of the two electrons must be opposite."

"When we separate two electrons and place them very far away, the relationship between the two electrons still exists. When one of the electrons is spinning up, the other electron far away must be That’s downspin, not only electrons, photons, neutrons and other particles, but also quantum entanglement.”

Gao Yuan listened carefully and nodded slightly. The boss of Xindao was indeed a boss. Academician Pan's explanation was the easiest to understand version of quantum entanglement theory he had ever heard so far.

Academician Pan paused for a moment, then changed the subject and continued: "However, quantum entanglement cannot be used for super-light information transmission, because no matter what operations we do on the A electron, people near the B electron cannot know, they We don’t know if we measured A, or any other operations we performed on A. No matter what we did on A, when the person at B measured B, there was a half probability of top spin and half probability of top spin. The probability is backspin, and in this process, no information can be transferred between the two electrons..."

Academician Pan talked a lot. To put it simply, the current quantum communication can only read, not write, so instant communication is not possible.

The reason why it cannot be written is that the earth's technology is not up to par and cannot escape the logical trap of quantum communication. This is the problem that Gao Yuan is preparing to solve.

So when Academician Pan finished speaking, Gao Yuan calmly continued: "As we all know, in communication, whether classical communication or quantum communication, the speed of information transmission does not exceed the speed of light. In other words, there is currently no instant communication over distance. "

"Because of the non-local nature of entanglement, the wave function collapses too fast. If you want to communicate, you must use a classical channel. However, in this way, the entire communication speed is limited by the speed of the classical channel. The upper limit does not exceed 3E8 meters per meter. Second."

"Based on the above, I redesigned such a communication protocol."

Gao Yuan said while writing quickly on the blackboard.

"First of all, communication parties A and B share the maximum entangled state of a pair of polarizations, such as 00+11, where 0 represents the horizontal polarization state and 1 represents the vertical polarization state."

"Secondly, A measures the particle in his hand, and the probability of measuring the horizontal or vertical polarization state is 1/2. Assuming that the measurement results in 0, and the entire entangled state collapses, then the polarization of the particle in B's hand must be 0."

"Third, B measures the particles in his hand. At this time, both A and B share bit 0. By repeating this many times, a certain number of keys can be accumulated..."

one two three four five six.

Gao Yuan overdue his time and showed a complete set of quantum communication principles in front of everyone, and this set of principles is the legendary quantum law!

Shock!

Unparalleled shock!

When Gao Yuan finished his speech, the audience was still silent. Everyone could not believe that the quantum communication protocol written by Gao Yuan had perfectly avoided the logical trap of quantum entangled bones, making quantum instant communication a possibility!

Perfect!

Awesome!

so amazing!

After the silence, there was an explosion of collective consciousness. The conference room was full of people, and thunderous applause erupted at the same time.
