Chapter 148 Optical Syrup
The single atom in the cage will show all the characteristics of quantum: spin, single-atom matter wave, single-atom electronic superposition state, single-atom Wheeler delayed selection and so on.

And cooling atoms is to reduce the speed of atoms from hundreds of meters per second to several meters and centimeters per second.

The principle of laser freezing atoms is mainly based on two points: [-]. An atom at a certain energy level will absorb photons that resonate at the natural frequency of its energy level until the atom undergoes an energy level transition.[-]. According to the Doppler effect, when the atoms travel against the light, the frequency of the laser will increase correspondingly, and when the atoms travel along the light, the corresponding frequency of the laser will decrease.

If an atom is compared to a train, then the nucleus is the locomotive, and the electrons are the train carriages. The laser blows the train like a strong wind, and the photons carried by the wind are like ghost passengers, attached to the train, and then leave.In the strong wind, the train decelerates continuously until it slows down to an extremely low speed, and by maintaining this speed at an extremely low temperature, these atoms can be captured.

As long as the frequency of this laser beam is slightly lower than the natural frequency that the atomic train can absorb, under the Doppler effect, the frequency of the oncoming laser beam will enhance the photon attachment dispersion, while the frequency of the downwind laser beam will decrease.

Oncoming ghost passengers get discounted fares and start boarding and disembarking, while ghost passengers coming downwind have increased fares and no chance to board.

This train only absorbs oncoming ghost passengers, and ignores passengers in the same direction, which is the most basic principle of laser cooling atoms.Of course, this kind of train will never be taken by anyone in reality.

This is the principle of the deceleration of atoms by optical syrup. As long as three pairs of laser beams facing each other are added in space, the speed of atoms will slowly decrease in six directions in three-dimensional space.

This is just the first step. When Zhu Cheng completed this experiment, he broke into a cold sweat. His cooling only reached 240μK, which is the limit of Doppler cooling!The lowest temperature on the earth can reach the level of 40μK.

If you want to make a quantum computer, you have a long way to go!
After finishing the experiment of cooling atoms, his head is getting bigger. This experiment is still the most basic step. Although this step slows down the atoms, the densely packed atoms are all crowded together. It is even more difficult for him to capture a single quantum.There are still a lot of problems waiting to be solved.

The winger went back to China very smoothly, and he received a call from Heim. This funny Nobel Prize winner actually called him at this time, which means a lot!Although his status in the highest scientific research circle is very low, he is also a Nobel Prize winner!
This represents another step forward for the world science center envisioned by Zhu Cheng!Although it is small, as long as you move forward steadily, there will be a moment to reach the other shore!

"How's the salary at Mr. Zhu Cheng's?" Haim's first sentence revealed his nature, greedy for money.Like a silvery dragon, he is not short of money, he just wants to make money!

Talking about money in the scientific research circle is actually a very sad issue. Some projects can still support experiments even if they are greedy, and there is still a balance in the end.In some projects, the belt is tightened and the scum is still poor, so maybe you have to add some by yourself.

"Eat meat and drink soup or just sit on the sidelines, it depends on your own projects and achievements." Wing Feng replied with a smile, and Haim was refreshed when he heard this, because the graphene he studied was a physics, The research on bionic materials is also Cree's top priority in biology.This determines that if he cooperates with Kerui, he is likely to be the corner of the meat!

"You wait for me in Shanghai for two days, and I'll be there soon." Haim decided to go and have a look. He didn't say his purpose, he just said that he was traveling.As a Nobel Prize winner, he should have received much attention.But because of his embarrassing academic status, he received less attention here, so he successfully obtained a visa and flew to Shanghai.

The two met at a century-old Jinmen restaurant in Shanghai, which originated from the opening of the city. After a century of cultural fusion, the dishes are acceptable to both Chinese and Western people.It is decorated in a simple and elegant Italian style, and the signature dish of Kinmen Restaurant served by the winger is the Buddha jumping over the wall, a soup rich in ingredients, including sea cucumber, shark's fin, and abalone.Swallow down endless aftertaste.

And Heim took out a document from his briefcase and handed it to the winger.With a smile on his chubby face, he said, "Look at this first. This is my latest research, about another direction of bionic technology, trapping."

Heim is a very keen person. In the past few years, graphene was very hot. He found a new way to stick graphene with a thickness of only one atom with tape!And now the hot quantum computer, he is eyeing it again!Regarding atom capture, he has found an excellent method, that is trapping!

"Flytrap is a perennial herb with regular bristles on the edges of the leaves, like the eyes of Venus. It is named Venus Flytrap. It is the same carnivorous plant as its distant relative Nepenthes. It It secretes honeydew to lure insects, and then the leaves close to trap the insects so they cannot escape."

Heim introduced his proposal, and he thought it would be promising. Unfortunately, the winger is a biologist, and he is not very clear about the purpose of this thing.

"For trapping monatoms! Find something that atoms like to get close to, and..."

The winger shook his hand, motioning Heim to stop.Said: "I don't know much about physics, you can talk to Zhu Cheng when you go back." He refused to talk about fields he was not familiar with, had no proven propositions, and jumped to conclusions easily, which was not in line with his character.The two chatted happily about the Nobel Prize! For example, Madame Curie's family, whose family is all Nobel Prize winners, Bohr and his son, etc., even learned from Heim.

Satisfied with food and drink, the two of them set foot on the No. 10 warhead. Heim envied this silver-white vehicle for a while. Self-driving cars are not allowed on the road in the Netherlands. Although the relevant laws and regulations are still being discussed, the No. 10 warhead It is still very early to enter the Netherlands.

"This is the No. 10 warhead that shined in the WRC? Awesome!"

What Haim was talking about was the dazzling performance of the Cree team in WRC this year, and it is currently the number one in the standings.Every competition area is a winning car, and a trend of 10-gauge warheads has been set off all over the world.

"We hurry up."

The No. 10 warhead is running on the road, and it is the first time for Haim to enjoy the benefits brought by this kind of automatic driving. It travels on the highway in a high-speed and silent manner. Even in the rest area, it will be charged all the time to ensure battery life. Deeply calmed Haim's perception.The battery life has exceeded his expectations.

"Didn't it mean 500 kilometers of battery life?" Haim asked in a daze.

The winger was dealing with matters in the biology laboratory, so he ignored his question at all.When he arrived at the Gemini Tower, Haim was a little intimidated by the height of the skyscraper, which was the same height as the clouds, and the spire was above the clouds!

"Is this the tallest building in the world right now, the Gemini Tower?" Haim muttered to himself, it really exceeded expectations. The silver-white glass exterior wall and the reflected sunlight made him dizzy.

A Nobel Prize winner should be very knowledgeable.Asking about everything doesn't fit his identity at all!The winger complained silently, which was mainly related to Heim's dislike of going out, especially after winning the prize.

Apart from that layer of aura, he is actually a very ordinary person. He will make a fuss when he sees something he has never seen before; when he changes jobs, he will care about salary, benefits and so on.

"Okay, let's go up."

Zhu Cheng is skeptical about Haim's statement that he traps cold atoms.Fortunately, there is also a solution in the book in the library, "Quantum History".He doesn't care about the idea of ​​capturing single atoms!It's just that Zhu Cheng feels that this person can be used as a benchmark to set up!There are thousands of gold in ancient times who bought horse bones and set a benchmark, and there will always be people coming to Cree's technology center!

"Well, in terms of salary, you can refer to the winger's treatment and lower it by one level. Five social insurances and one housing fund, paid leave, marriage leave, maternity leave, year-end bonus and patent royalty sharing and other benefits, also refer to the winger." Zhu Cheng said to Hai Mu set a standard. After all, this is a Nobel Prize winner, and he should be given certain respect and certain benefits.

The two left the office, and Haim asked weakly: "What is the standard for your salary to be downgraded? How much money can you make a year?"

"I don't know, my wife takes care of it." The winger replied.

When Haim really understood the salary and benefits, he was completely relieved, which was much better than when he was a professor!Soon Zhang Qingyu came out with a residence permit and handed it to Haim.The time limit is 3 years, and if it expires, you can apply for it again.

The winger returned to China and did not participate in any activities, did not attend any social activities, and did not accept any visits. He quietly conducted experiments related to superbugs in the laboratory.With the deepening of research, the human stem cells that they want to be immune to all viruses are getting closer.

Zhu Cheng often brings Lilia to an office. She has completed all the alien biological experiments, and now it's time to integrate into human life.

As for Lilia's future, Zhu Cheng could only take one step at a time, but he didn't know the reason why Trieste gave him this gift, at least in the time of biological research, there was nothing special about it.

It was only when Lilia started to study that Zhu Cheng fully understood the horror of Lilia!The basic learning was completed within a few days, and the pace of learning was continuously accelerated.

The coaching teachers change every few days!Her learning speed exceeded Zhu Cheng's expectations.But on the earth where brain technology is relatively weak, I don't even know what's in that little brain!
Is it related to the long-term freezing that caused such a high learning efficiency?Zhu Cheng was a little curious.He decided to ask Trieste.
