Hearing this word coming out of Academician Pan's mouth, Xu Yun's pupils suddenly shrank, and he lost his voice in an extremely rare moment:
"Director Pan, fifteen photons? Has the technical reserve of Liangxin Laboratory reached this level?"
Photon entanglement is a core indicator of the basic ability of quantum information processing. The more entangled photons that are manipulated, the quantum information processing ability will increase exponentially.
This thing has a scientific name, called multi-photon entanglement, which involves the concept of quantum teleportation.
It’s okay if you don’t understand this sentence, there is a more straightforward explanation:
Quantum teleportation can be regarded as an infinite microscopic science fiction teleportation array.
Yes, it's the kind of teleportation array that draws a circle and you stand in it, and then after a burst of green light, you are teleported to another place.
Its principle is to transmit bit information out of thin air to another location through the entanglement relationship of photons in a classical channel, that is, in compliance with the theory of relativity.
A person or something can be regarded as a macroscopic object composed of countless microscopic particles. Therefore, as long as the technology is perfect enough, it is theoretically possible to decompose, transport, and reassemble a person.
Of course.
Quantum teleportation can only be said to be the prototype of a teleportation array. There is still a long way to go before a teleportation array can truly have the ability to teleport macroscopic objects.
12 grams of carbon atoms is 1 mole, which is 6.023*10^23.
If a person weighs 60 kilograms, assuming it is all composed of carbon atoms, then there are approximately 5,000 moles of atoms, which is 3*10^27.
To describe the state of an atom, let's calculate it in terms of ten degrees of freedom.
Then to describe a person, one needs 10^28 degrees of freedom - few students who do not understand the concept of degrees of freedom can convert this word into money, but what the cutting-edge now has is just a machine that transmits fifteen degrees of freedom.
Just photons.
Assuming that World War III does not occur and the research direction is correct, it may take 800 years for humans to have a teleportation array that meets standard cognition.
But in addition to this, there is also a technological singularity theory, which believes that the technological singularity will be reached in 2075. The current discussion of this view is so intense and sharp that Lily’s brain is about to burst.
At present, academician Pan's team has completed the entanglement of five-photon, six-photon, eight-photon and ten-photon for the first time globally.
At the same time, it is worth mentioning that photon entanglement is not a so-called "World Champions Cup" like a certain mobile game. In fact, only locals are participating in self-entertainment research. This project has been carried out in various countries and laboratories around the world.
It occupies a considerable amount of research resources.
For example, Alexei Kitaev, John Martinis, and Austrian physicist Peter Zoller, winner of the 2006 Dirac Prize, all lead research teams in this area.
Our country calls it quantum computing superiority, while Yingjiang calls it quantum supremacy. The leader is the famous Gu Ge.
Now that Academician Pan’s team is about to launch a fifteen-photon entanglement experiment, how can Xu Yun not be excited?
As a practitioner in the physics industry in his previous life, he almost subconsciously wanted to agree to Academician Pan's invitation.
But when the words were about to leave his mouth, he was stopped abruptly.
There is no other reason than that I am really not suitable to join this kind of team at this time.
At present, the technical barriers of the fourth generation imidacloprid have been broken through, and the fifth generation finished product is just ahead. Whether it is the patent transformation of research results, follow-up papers or even commercial derivatives, I am not allowed to get away at this time.
Not to mention the mysterious claustrophobic space, Xu Yun had a hunch that the next dungeon might not be opened very far away.
No matter whether it is the 1665 copy or other new time and space that is opened at that time, as long as Xu Yun completes the relevant tasks, he will definitely get new rewards when he returns.
If you join Pan Shuai's team, it will be almost impossible to escape in the short term, and subsequent progress may be greatly restricted.
Therefore, after some internal entanglement, Xu Yun simply described the project he was working on to Academician Pan and said apologetically:
"Director Pan, I may not be able to join your team this time."
"The fifth generation imidacloprid...this is also a good research direction."
After hearing what Xu Yun said, Academician Pan nodded slightly without insisting too much:
"In this case, I won't force you. Let me go for now. Mr. Tian has gained a good apprentice."
Tian Zhigang is 66 years old this year, and Academician Pan was born in 1970, so he can be called Mr. Tian.
Then Xu Yun briefly chatted with Academician Pan for a few words, and then the two separated and left.
Looking at Pan Shuai walking in the opposite direction, Xu Yun suddenly had another hunch in his heart: he might not be able to see Pan Shuai for a long time in the future.
Xu Yun then calmed down, turned around and continued walking towards the West District AED.
AED generally refers to automated external defibrillator in the encyclopedia, but on the HKUST campus, AED refers to the West Branch of the HKUST Library.
The AED of HKUST is 12 stories high. The building appearance is L-shaped. The entrance is a very beautiful sunshade arch. You can often see a huge fat three-flowered pig named Sanpang around. In addition, HKUST has a solution team.
The big star of Maxwell's Equations, and the Western District master Dabai who can push the basic elements. It is said that the GPA of the cats in HKUST is above 3.8...
Ahem, let’s get down to business.
The biological information Xu Yun was looking for was distributed on the 1st and 11th floors. After using the all-in-one card, he started to check the books on the first floor.
Biology journals and physics materials are located on two nearby bookshelves. When Xu Yun came here, there were two girls standing shoulder to shoulder in front of the physics bookshelf, looking for some information.
The two girls seemed to be roommates or classmates, and they should have a good relationship. After seeing Xu Yun appear, they just glanced at each other briefly and continued to find the books they needed.
This chapter is not over yet, please click on the next page to continue reading! Xu Yun naturally had no idea about the two alumni who were complete strangers, so he started looking for books one by one from the left side of the bookshelf.
"Insect proteins...specifically bind to receptors..."
Although there are now electronic devices that can directly search and consult, Xu Yun still likes the feeling of holding a card and shaking it as a fan, searching for books in rows.
It's not that he is really hot. The wind blowing from the card is just like that. He just likes to hold it in his hand and play with it, just like some people like to turn their mobile phones.
The two girls looked at the books from left to right, while Xu Yun looked from right to left. Therefore, soon, the two girls came close to each other back to back in the middle.
The library was very quiet at this time, and I don't know if it was because I was a little tired of looking for books. One of the girls' voices was not very low, and it reached Xu Yun's ears clearly:
"Ning Ning, it's hard to find books describing Newton's life. This row used to be filled with theoretical books."
Xu Yun was not the kind of person who liked to eavesdrop on other people's conversations, but the word Newton in the girl's mouth subconsciously reminded him of the calf in the dungeon who loved to convince others with reason.
So my ears immediately perked up and I turned my attention to the next door.
Facing the complaints from her companion, another taller girl smiled:
"Okay, okay, Yueyue, please stay with me for a while, and I'll treat you to a drink of Mixue Bingcheng later..."
'Yueyue' sighed after hearing this, and rubbed her hands as if accepting her fate:
"Hey, okay, okay, I'll look for it with you again. Why are you so interested in Lord Niu's life? You don't really believe that those pairs of Anta are products of the same generation as Lord Niu, right? Professor Lu
Didn’t we all say it in the department yesterday, that it was just a little trick using substances similar to transition state esters of six-membered rings, purely to ridicule some people.”
"I just want to find some information to confirm. After all, it's a coincidence, isn't it?"
For some reason, when he heard this sentence, Xu Yun, who had his back to the two of them, seemed to see the tall girl's soft tone but firm expression in his mind:
"Yueyue, isn't it recorded in history that Yang Hui's Triangle was brought to England by an Eastern businessman, and it happened to fall into the hands of Newton, otherwise Yang Hui's Triangle would have been called Pascal's Triangle internationally, just because of Newton
Endorsement, this triangle will be named after a Chinese person..."
snap——
A crisp sound of books falling to the ground suddenly interrupted the conversation between the girl and her companion.
Fortunately, the location of this bookshelf is relatively remote, so it did not attract the attention of other people in the library.
After a moment, a surprised male voice came from behind:
"Classmate, excuse me, what triangle did you just talk about?"
