Chapter 496 Quantum Communication (23)

"The technology used has something to do with monsters."

There are relatively few technical parts in the application materials of the project, so Chen Shen had to explain to Wang Qian: "The principle of this technology is like quantum entanglement. When one side changes, the other side also immediately changes. , that is to say, it is theoretically a communication technology without time delay.”

Wang Qian thought for a moment, "Quantum entanglement?"

"I remember that quantum communication is not a form of instant communication?"

As soon as Chen Shen heard it, she knew that she wanted to go somewhere else.

Quickly pulled her back: "It's just a technology whose principle is similar to quantum entanglement, and it's not realized through quantum. It's just that the specific technology involves the monster project, so it's not convenient for me to say too much."

Quantum communication is indeed not a means of instant communication, it is actually a way of secure communication.

Some people think that the quantum entanglement effect can be used to communicate between a pair of associated quantum, when the state of either party changes, the state of the other party changes instantaneously no matter where they are, so that there is no delay in communication.

However, limited by the quantum superposition state and the quantum collapse effect, this method of using quantum to realize instant communication has not yet been theoretically realized in the current cognition.

Quantum superposition state means that the position and state of quantum appearance are probabilistic and not deterministic. It can appear here or anywhere, and it may be this state or that state.

Before being observed by the observer, its state and position are not determined, it is both this state and that state, both in this position and in that position.

Two opposite states exist in the quantum at the same time, which is the counter-intuitive quantum superposition state.

Only after being observed, the quantum state will enter a definite state from the magical superposition state just now, which is quantum collapse.

If you want to apply the phenomenon of quantum entanglement to instantaneous communication.

So the reality is like this -

Set in two boxes, each with a special coin, they are in a superposition state, both heads and tails, similar to the situation where the coin is standing up.

In special rules, this is a superposition state, which can be regarded as the coin at this time is both heads and tails.

At the moment of opening the box or performing other observations, the coin will fall down, and everyone will know its positive and negative status at this time, and when one coin is observed to be positive, the other coin will immediately become negative. vice versa.

In addition, any operation on the coin in the box will also immediately cause its state to be determined, which is quantum collapse.

Party A and Party B who want to communicate each leave with a box, and they are very far apart, and the distance is calculated in light years.

When Party A wants to communicate through the coins in the box, it operates on the coins in the box.

After the operation is over...

There is no follow-up.

Communication was cut off.

Among the two parties who are separated by light years, except for the entangled coins, they cannot quickly obtain the news from the other party by other means.

After Party A observes the coins, Party B has no way of knowing Party A's actions, let alone the status of the coins in his box has been determined.

Because any observation behavior will lead to the determination of the state of the coin, neither Party A nor Party B can make any observations on the coin before communication, even if an instrument is used to record the state of the coin, the state of the coin will also be determined.

This leads to the fact that when both parties open the box, neither party knows when the coin in the box fell. Whether it was the behavior of their own observation that caused it to fall, or whether the other side observed the coin first, causing it to fall. It fell down before I opened the box...

In the end, if the two parties want to determine who observed the coin and caused it to fall, they still have to confirm the news with each other through other means of communication...

Turned around and returned to the original starting point.

Because of this, quantum entanglement cannot be used to transmit information.

It can only be used as a means of encrypted communication.

In the process of two-party communication, once a third party eavesdrops, it is an additional observation, which will definitely lead to an abnormal quantum state. As long as the two parties in the communication check the quantum state, they can immediately know that there is a third party stealing information. .

This is also a kind of "don't stretch out your hand, you will be caught if you stretch out your hand".

When Chen Shen said this, Wang Qian immediately understood, "I thought you had already cracked the property of quantum measurement collapse."

Chen Shen was speechless, "Where is it so easy..."

"If you say it, it's not surprising that you have achieved any results..."

Wang Qian is the one who is truly speechless.

Chen Shen has succeeded in so many projects over the years.

In her heart, even if Chen Shen really cracked the effect of quantum observation, that is, the collapse, there is nothing surprising.

"It's better to submit this application as soon as possible. It's better to prepare earlier." Since discovering that the opposite monster was born ahead of schedule, Chen Shen has always had a sense of urgency in his heart.

Wang Qian nodded, and immediately submitted the application materials through confidential channels as he said.

But this project application is different from the past.

Less than an hour after the materials were submitted, Wang Qian called to inform that the project had passed the approval and could officially start.

Even Wang Qian expressed surprise at this speed.

This kind of approval was so fast that it seemed that Wang Yinian and the others had been waiting for Chen Shen to submit the materials, and then approved immediately.

Although the past projects can be passed smoothly, they usually have to wait for two or three days. Please study carefully...

Chen Shen, who received the news, did not waste time, and immediately submitted the materials of the prepared particle beam emission device and space crystal energy guidance device.

Both of these were picked out from the technology of the drone armour.

After all, these two sets of devices are going to be sent to the moon, so naturally they cannot be installed on the body of the mecha like in the movie.

Even if it is a Tibetan antelope or a devil ray, it is still a difficult and long-term task to transport a mecha starting at a thousand tons to the moon.

Not to mention transporting six UAVs at once.

Moreover, it is impossible for UAV A to adapt to the environment of the moon, and it is useless to send it up.

After careful calculation, it must be the most cost-effective to strip these two sets of devices from the mech and send them to the moon alone.

While Chen Shen was working hard for the man-made wormhole, a second monster was quietly ushered in on the other side of the ocean...
