Ship Girl: Start with an Aerospace Carrier

Chapter 90 Quantum Radar (Please subscribe, ask for a monthly pass!)
"Commander, look that this system is analyzing the quantum radar, why don't we take advantage of this time and go for a walk, it's boring to stay in the room all the time."

Luanniao hugged Jiang Ran's arm and began to act like a baby.

Now she has been fed by her own commander, so naturally she doesn't want to stay in this small room anymore.

Jiang Ran looked at the time required for the reverse analysis of the system, then looked at the Luan Niao beside him, and quickly refused: "No, you have to go by yourself, I won't go shopping with you!"

After finishing speaking, he lay on the bed by himself, wrapped the quilt up by the way, took out the game console he had made, and started playing the game.

Rather than going shopping with his own girls, Jiang Ran prefers to stay in the dormitory every day, and it is best not to go anywhere.

"Unless I don't want feet anymore, it's impossible to go out with these girls!"

After all, if you go shopping with your own girls, it will take a whole day to go shopping, and there is no place in the world's shopping malls for boys to rest.

After walking around for a day, Jiang Ran felt that the legs might not be his own by then.

Therefore, in this world, going shopping with girls is more tiring than the earth in the previous life. Only those with serious mental illnesses should go there!

At the same time, he felt strange in his heart, forget what Jian Niang said.

But why those ordinary girls, on weekdays, obviously look very delicate, their physical strength is not very good, and they can't even unscrew the bottle cap.

How come once it's time to go shopping, you won't feel tired after walking for a whole day. There are even quite a few girls who wear high-heeled shoes to go shopping, and after a day of shopping, they look lively.

Jiang Ran thought for a long time but couldn't figure out why.

The ordinary girls on earth in the previous life were like this, and the current ship girl is still like this. . . .

After hearing what his commander said, the Luanniao on the side immediately became unhappy.

Then, she threw herself on Jiang Ran, hugged him, and shook him very hard.

"Oh, Commander~~~ Let's just go for a walk on the beach outside, and I won't let you accompany me to the shopping mall, okay?"

Luanniao's voice was sweet and a little cloying, and she also increased her strength a little, continuing to shake her lazy pig-like commander.

At this moment, Jiang Ran was also a little dizzy from her constant shaking, and the sweet and greasy voice of the luan bird kept ringing in Jiang Ran's ears.

At the same time, the unique faint fragrance coming from the woman was constantly affecting Jiang Ran, making it impossible for him to play the game properly.

After a while, Jiang Ran really couldn't stand his mother-in-law being so teased, so she quickly put down the game console in her hand, looked at the woman beside her, and said helplessly:
"Okay, okay, stop shaking, your head is dizzy, I'm going! Can't I go?"

After listening to his commander's words, a satisfied smile appeared on Luanniao's pretty face, as if he was happy that his plot had succeeded.

After her commander, who likes to stay at home, got out of bed, she took his arm affectionately, smiled, and said:
"Commander, you can't stay in the dormitory all the time, you need to go out for more activities. You see, Commander Chen Xinyue next door is often with her Dong'er. Can we do the same?"

Hearing this, Jiang Ran rolled her eyes, Chen Xinyue planted lilies with her mother-in-law every day in the room, do you want to plant them too?

Looking at the Luan Niao who was smiling happily beside him, Jiang Ran said angrily: "Let's talk about it first, just walk casually by the beach, shopping or something is not allowed!"

"Enenen, I see, really, Commander Stinky, can't you come out for a walk more?" Luanniao took Jiang Ran's arm and began to complain.

Facing the complaints from his own ship's mother, Jiang Ran didn't try to defend herself.

Instead, she just silently took the little white hand of Luanniao and strolled leisurely by the seaside.

There are already quite a few people on the beach now, and it is naturally unlikely that the two of them will kiss each other like last time.

In such an environment with a lot of people, according to their personalities, neither of them could do such a thing.

Jiang Ran and Luanniao just kept walking outside, lying on the beach or reef for a while when they were tired.

If it is hungry, Luanniao will take out all kinds of delicious food from its own space to eat.

Now, anyway, the other girls in the port area haven't come back yet, so the two of them just kept playing outside.

It wasn't until evening that the sky became darker, and the two returned to the dormitory one after the other.

After returning to the dormitory, I found that the girls in the port area had also returned to various rooms.

Because of the late time, Jiang Ran and Luanniao did not go to other girls, but tiptoed back to their room.

The next morning, after the reverse analysis of the quantum radar was completed, Jiang Ran started calling his girl on the communication channel.

After all, in the face of stealth fighters, although some of them have meter wave anti-stealth radars on their hulls, the effect of that is not as good as quantum radar.

Moreover, the meter wave radar can only serve as an early warning for stealth fighters, and cannot guide missiles to shoot down fighters at all.

Quantum radar is a kind of radar designed based on the principle of quantum entanglement, which can effectively identify stealth fighters, even if it is a radar-optical double-stealth material.

Quantum entanglement refers to two microscopic particles, no matter how far apart they are, changing the state of one of them will cause the other to change accordingly, which is called ultra-distance perception.

The detection process of quantum radar is to use pump photons to pass through (BBO) crystals, and generate a large number of entangled photon pairs through parametric down conversion.

The polarization states of each entangled photon pair are orthogonal to each other, and the entangled photon pairs are divided into detection photons and imaging photons. The imaging photons are retained in the quantum memory, and the detection photons are emitted by the transmitter and reflected by the target before being received by the quantum radar. .

The detection performance of radar can be improved according to the entanglement correlation of detection photon and imaging photon.

Compared with quantum radar without entanglement, the resolution of quantum radar with entanglement increases at a quadratic rate.

After the reverse analysis is over, it will be on the column of the technology tree.

Jiang Ran also discovered that a technology called quantum communication technology was lit up.

That is to say, my future communication or the guidance method of missiles can all be completed through light quantum encryption.

Compared with traditional radio, this method is less likely to be intercepted or monitored, and it is even less likely to be electronically interfered with.

At the same time, after replacing the missile with such technology, it can also be used in better cooperation with quantum radar.
