Chapter 5 Bell's Inequality

   "Eh? You live next door?"

  Liu Xiaoke was holding the key to open the door, looking at Wang Yi who came out to throw out the trash beside him and said with a little surprise.

   And Wang Yi only opened the door after hearing her coming back. After all, she helped him, and he is still a new neighbor. Of course, the most important thing is to ask for the wifi password. After all, it will take tomorrow to pull the network cable.

   "Yes, thank you for your help today. Add a friend. If you have any trouble, you can find me."

  Wang Yi shook the phone in his hand.

   "I didn't expect you to look young, but you have quite a lot of routines."

Liu Xiaoke has a look of seeing through. As a beauty, she is naturally often approached by various excuses to shake her signal, but she did not reject Wang Yi's act of adding friends. For some reason, she felt that she was cheated by pyramid schemes at this age. The little boy who walked had a natural sense of trust.

   "That's right, Miss Xiao Ke is a beautiful woman."

  At a time like this, Wang Yi naturally wouldn't make fun of himself and say that I did it for the wifi password.

   "By the way, how much is your wifi, I can pull the network cable tomorrow."

  Wang Yi casually stated his main purpose.

   "Eight eight, I want to watch dramas tonight, don't download movies."

   "No, thanks."

   After speaking, Wang Yi threw away the trash and returned to the room.

   After connecting to wifi, Wang Yi logged into the student account of his alma mater Academy of Sciences.

  After graduation, you can also use the school database, which is definitely a benefit for those who need it. Every school has to pay a large amount of fees for the database every year, and these are free and open to students.

   Otherwise, once an individual downloads the required information, there will be a charge, and many of them still charge US dollars.

  In this world, the protection of intellectual rights and interests is quite in place.

   Then Wang Yi began to search for the papers he needed and downloaded them, all of which were related papers on quantum mechanics.

In the three years in the wizarding world, with the help of overclocking, he has enough knowledge to master a large amount of knowledge. When studying, he will also encounter various problems. Relying on the memory of overclocking, he can determine the places where these problems occur and where they are. Quantum mechanics has some inextricably linked and complementary.

   But it is a pity that he used to focus on algorithms and electronics. Quantum mechanics can only be said to have heard some generalizations, and now he is starting to make up for it.

  First read all the things summed up by previous people to see if you can get inspiration and help.

   In addition, he also completed the submission of the first manuscript he made.

  A paper on pure number theory, a proof of Goldbach's conjecture (please don't insult me, I can't prove it).

  The reason why Wang Yi can study mathematics is related to one of his self-created spell models.

  Because he has been staying in the Mage Tower all the time, Wang Yi has a serious lack of assistants, which makes him attract the attention of the undead, and finally he focuses on the skeleton.

  But ordinary skeletons are too rigid, and the summoning process is too simple. It is because of this simplicity that Wang Yi feels that he has no way to start.

Finally, relying on overclocking and his own mathematical skills combined with the practice of spell models, combined with some mathematical theories from other worlds, he completed the collision of the sparks of the two civilizations, allowing him to complete the process of 'because...so', and thus carried out the summoning of the skeleton. improved.

  Conjecture itself is one of the achievements, but in fact the most important thing is the mathematical tool perfected by combining some novel viewpoints from other worlds.

  Now Wang Yi has been able to give certain specific programs to the skeletons, allowing them to do specific things, which is far beyond the original ability of the spell model that summons the skeletons.

  So he has full confidence in this thesis, and it is quite handy to write, as long as he pays attention to some foreign mathematics experience and needs to complete the proof process.

   After looking at the prompt of Submitted to Journal, it means that the submission has been successful, and the next step is to wait.

   For such a big explosion, the review will definitely be very cautious, and it is quite normal for more than a month.

  Because he knew it would take a long time to wait, Wang Yi was the first to send this out.

  As for being famous and getting attention, Wang Yi doesn't care. Although he does have a lot of secrets, in fact, this kind of pure number theory conjecture has limited influence even if he wins an international award because of it.

  In this era of smartphones, people who eat melons are more concerned about various celebrities and gossip.

   There may be shocks in the academic world, and it may also attract the attention of your alma mater and some attention from higher-ups, but the attention that the field of number theory can attract is relatively controllable.

   It’s not that he took out a perpetual motion machine.

  It’s just that Wang Yi used to be a complete pragmatist, and he used ready-made knowledge to learn, and his thesis was just coping, lacking experience in this area.

  This kind of paper in the field of pure mathematics should have been better submitted to professional journals such as "Annual Report of Mathematics", but he directly submitted it to "Science" in this world.

   And the famous "Science" itself is still the hardest hit by civil science bombings. Goldbach's conjecture receives a large number of submissions every year almost like perpetual motion machines.

  Wang Yiqi's title perfectly fits this point...

   It's just that Wang Yi, who didn't know much about this aspect, put it aside after completing these operations, and began to pay attention to some papers he needed.

   Directly turn on the overclocking state, and look at the bottom, and the extra time will start to gradually understand the relevant papers.

  Finally, he locked a major doubt he encountered on the 'Bell Inequality'.

  God did he roll the dice!

  This problem has also been bothering the mages in other worlds. A group of people support that everything in the world completely follows a certain law, without exception.

   It is impossible to predict, it is just that there are some hidden variables that have not been discovered, perceived.

  Another batch was the exact opposite.

   This can be said to involve the issue of the law of causality, and mages attach great importance to this, because they can really be used.

   "Good guy, can this formula be established? This can be verified? Sure enough, some problems only need to puncture a layer of paper windows."

  Bell's inequality itself is not complicated, but it is more important because of its relative simplicity. Mathematics will not lie.

   In the 1980s, the second generation of testing instruments had almost completed the falsification of Bell's inequality.

  The third generation of testing instruments is more accurate.

  But for Wang Yi, what he needs more is this idea and verification process to verify his troubles on the magic side.

  He can use similar experiments to complete the verification of his troubled problems!

   This gave Wang Yi a sense of comfort that he was about to pursue the truth.

Many people have heard of quantum entanglement, that is, entangled photons can pass through one state to determine the other. Bell and Einstein both believe that this is actually the photon is endowed with some kind of information from the beginning, or that they follow a certain state. The formulas and laws are all hidden variables written in advance, so the entangled photons are kept in step, and there is no connection between the entangled photons.

  Bell specially created Bell’s inequality in order to support Einstein. If it is true, Einstein is right, and there is indeed some kind of hidden variable.

   To verify this is to assume that there are hidden variables and then design an experiment to prove or falsify.

  Because photons are still electromagnetic waves with wave characteristics, waves have amplitudes and polarization directions, so different polarizers can be used to make entangled photons 'answer questions', and statistics can be made through different results of different photons on different polarizers.

  Relying on high-precision experiments, increasing the amount of data collected can be statistically incorporated into Bell's inequality to see if the statistical results are consistent, so as to judge whether the photon has been written in some hidden variable in advance or not...

   This made Wang Yi see arcane brilliance blooming in his eyes, and his heart was surging.

   "Sure enough, the brightest essence of a civilization is the knowledge summed up by this civilization."

  Bell's inequality is not complicated, and the principle of the experiment is not complicated. The most difficult thing is the precision and the instrument, but it is this seemingly simple inequality and experiment. This kind of whimsical thinking can solve the problems that plague the forefront.

   Now someone has completed the verification of the quantum world, and the rest is Wang Yi's verification of the magic world...

  But because there are too many trivial things in life now, almost all the extra time is spent on code words, so the integrity rarely bubbles up
