"Today will be a glorious day in the history of Mit, and we are very honored to have Mr. Jun Xin, a world-renowned mathematician, chemist and physicist from Princeton University, an exchange student from Princeton University. It's hard to imagine how an eighteen-year-old could have achieved such a lofty status, but we believe that there are miracles in this world. And today, our protagonist here is a miracle maker, and he will surely create a great miracle again on this stage. Professor Quelen, who was the inviter of this seminar and also the moderator of this meeting, was full of confidence in Junxin's remarks after listening to Junxin's discussion before the start of the seminar.

"Let's have a letter from you!"

A burst of warm applause rang out, and in the midst of the applause, Junxin calmly walked to the center of the stage.

"Thank you MIT for giving me this opportunity, Professor Quelen for the invitation, and thank you to our beautiful and charming Miss Mandani for providing me with all the services at Mit, thank you!"

"I need to give you an explanation of the topic that I am going to talk about today." After the applause dissipated, Junxin said solemnly, "The original topic of the report was the proof and research of the four-dimensional Pang Jialai conjecture. However, in the first hour of the meeting, after discussion with Professor Quelen, I finally decided to change the theme, which may cause some confusion to some of the students here, and I would like to apologize to you first. ”

"Alright, let's get down to business now."

"I would like to ask all of you here a question, a question that has caused a huge sensation in the physics community, is God rolling the dice?" Junxin said calmly, "I'll just ask a random question, please ask the gentleman or lady with seat number 10 row 21 to answer your opinion and answer to this question, can you?" ”

As soon as Junxin's words fell, a woman with a delicate face stood up and replied: "Your number, dear sir, I am Mary, a graduate student in the Department of Mathematics, and I am not very clear about quantum mechanics in physics, but what I do know is that this question seems to be a long-term debate between the great scientist Einstein and Bohr, Einstein believes that God does not roll dice, while Bohr thinks that God rolls dice. I've seen an experimental report that seems to have proved that Einstein's argument was wrong in 1964 and has been solved, so God is indeed a roll of dice. ”

"Does anyone else have a different opinion?" Junxin smiled and motioned for her to sit down, and then continued to ask.

"Hello, sir!" A boy also stood up and said, "Many rules of quantum mechanics have views or starting points that are contrary to normal thinking, among which the statement about whether God rolls the dice is mainly derived from a quantum transmission beyond time and space, let's call it a transfer for the time being, and Einstein proposed that light is a basic constant in physics, and there can be no matter or particles faster than the speed of light." ”

Junxin nodded, did not continue to ask questions, but officially started today's report: "Very good, everyone said it is very good. That's what I'm going to start with today, about God rolling the dice, and what leads to the concept of quantum communication. ”

"The original plan was to explain the four-dimensional Pangjialai conjecture, and our report still has to start from this conjecture."

"After I proved the four-dimensional Pangjialai conjecture, on the basis of continuing to study it, when I tried to use various methods to solve the three-dimensional Pangjialai conjecture, I inadvertently wrote the following equation through one of the ideas." As he spoke, Junxin put his handwritten magnified equation on his projector.

“…… Those who know me well may know that I have published several articles on superstring theory in the Physical Review Letters this year, which is about mathematical physics, so I myself have a certain amount of research on physics, and when this equation appeared, I immediately realized that this was the quantum mechanical equation that triggered the debate between Bohr and Einstein about the theory of quantum entangled states in 1935. ”

"So, what is a quantum entangled state? With the help of Professors Dyson and Witten, I was able to find a series of papers in various journals and handwritten manuscripts in the Princeton Library, based on which I organized the relevant ideas and the context of research development. ”

"In 1967, at Columbia University, Einstein's challenge to quantum mechanics was taken over by a young man. At that time, John Krauser was looking for a topic for his doctoral thesis in astrophysics. After reading a little-known paper written by the Irish physicist John Bell, Krauser thought he had found an experimental way to verify who was right and who was wrong. In this paper, Bell has discovered how to verify whether entangled particles communicate in a ghostly way, or whether there is no ghost at all, and the state of the particles is like a pair of gloves has long been decided. Bell even used mathematical calculations to prove that if this ghostly effect was not true, then quantum mechanics was wrong, as Einstein thought. Bell is a theoretical physicist, and his paper shows that this problem can be solved if you can build an instrument that can make and compare entangled particles in large quantities. ”

As Bell imagined in his paper, Krauser designed the instruments that would put the controversy to rest. Krauser's instrument could measure thousands of entangled particles and then compare their spin states, but as the results were revealed, Krauser was surprised and displeased. Krauser repeated his experiments over and over again. Soon after, the French physicist Alain Aspey conducted more definitive tests, with more definite results and all doubts dispelled.

Krauser and Aspe's results are quite astonishing, they prove that the equations of quantum mechanics are correct, that entanglement is real, and that particles can be connected across space – and that measuring one of them can indeed affect its distant companions in an instant, as if crossing spatial constraints. Einstein's "ghostly telepathic effect", which Einstein thought was impossible, did exist. ”

"This is a very interesting thing, the characteristics of quantum entanglement, proves that there may really be a super-distance effect, and the existence of this over-distance effect also shows that quantum communication technology is a practical means of communication technology."
