Chapter 529

"The game?"

Emilia didn't quite understand, but she still sat opposite Lena. She only touched the rules of this card game, but she didn't actually play it.

"Don't worry, we won't use the original rules, but the rules I made."

Lena shuffled the cards, put one card back up into alimia's hand, and put the other card on the table.

"Now we stipulate that if the card on the table is the same color as the card in your hand, then you win. If it is the opposite color, then I win."

Emilia nodded, then opened the card in front of her, which was a red card.

And Laina opened the card in front of him at the same time, not red, but black card.

There are only two colors of this card, black and red, so the chances of alimia winning should theoretically be 50%.

But seven times in a row, alimia lost.

Every time, when alimea turns over the cards in front of her, Lena can always turn over the cards of the opposite color, which makes alimea a little annoyed.

"Even if it's luck, it's unreasonable!"

Emilia seems to have been immersed in the game, forgetting that they are actually discussing academic issues.

"Well, let's change the way. If the colors are different, it's your victory. If the colors are the same, it's me."

Lena smiles and says nothing more.

Emilia thought about it, and seemed reasonable, and nodded in agreement.

Only Laina issued two more cards, one of which alimea opened, was a black card, and then Laina opened the card in front of him, which was also a black card.

Emilia lost again.

It's seven times in a row, each time it's the same color, and alimia loses again.

"It doesn't conform to the common sense of magic, Lena. You must be cheating!"

Alimia puts down her card and accuses Lennard.

"Ha ha, I'm cheating."

Lena's answer choked allimi Arden. How could there be a banker who simply admitted to cheating?

"Then, Emilia, can you see how I cheated?"

"Er... The order of the cards was determined in the shuffle in advance?"

Emilia was puzzled by this question and hesitated for a moment before giving the answer.

"That's the problem."

Then Lena said with a smile.

"If each card in the game just now is regarded as a particle in the quantum system, and red and black are its spin states, then what we simulated earlier is actually a form of quantum entanglement."

Seeing that alimia didn't quite understand, he went on to explain.

"Quantum entanglement phenomenon shows that when we know the state of one particle in the system composed of two entangled quanta, we can know the state of the other particle, just like when we know the color of one card in two games, we can also know the color of the other card."

"So, in fact, just how to play is lost..."

alimia seems to be still struggling with the game's win or lose, some not very satisfied with the said.

"It can be understood that there is no doubt that I cheated in the game just now. This is also the view of mages on quantum entanglement, that is, there must be a magic element in quantum entanglement to describe the quantum state. In short, cheating should also be included in the theory. We allow quantum entanglement to cheat, but quantum entanglement can not The theory has to be clear about how it cheats. "

Lena shrugged.

"Mr. Braggs and Mr. Alberton think that the evil dealer has determined the order of the cards before the game starts, that is to say, in the quantum entanglement phenomenon, the state of two particles has been determined at the beginning, and our observation is just to observe what has happened for a long time."

At the moment of separation, the spin state of two particles has been determined, and this kind of information is transmitted along with their separation. Therefore, the observation of the spin state of particles has actually happened for a long time. Therefore, there is no limit on the speed of light. In other words, the speed at which the observer knows the information is really below the speed of light.

This is a conclusion based on general relativity. From people's common sense, it is more in line with common sense. Realism plays an important role in it.

"In this conjecture, the state of the particle is certain and has been determined from the beginning. The particle itself is an objective existence, and its spin state is also an objective reality."

Said Lena with a slight sigh, and then looked at alimia.

"But there's another guess, another way to cheat."

He took out two cards, one red and one black, covered the surface of the card with magic, and immediately turned the two cards into the same red."That is, the dealer actually randomly draws two cards, even he does not know what color these two cards are, but he has a special way to change the color at the moment of opening the card, so as to win."

"How could it be..."

alimia blurted out subconsciously, but soon she noticed the problem.

Because this is exactly the reflection of the wave function collapse and the observer effect in quantum theory.

"At the moment of opening the card, it is equivalent to the moment when the mages measure the particles. At this moment, the wave function of the quantum system collapses because of the observation, and the state of the particle is determined, thus affecting the state of another particle entangled with it. This is the process described in the quantum theory."

Said Lena, putting two cards on the table, one black and one red.

"This is the collision between the classical magic system and the quantum magic system, behind which lies the existence of realism."

According to the classical magic system, the existence of matter is objective and real. No matter whether the observer exists or not, matter keeps its original state. Although the collapse of wave function is caused by the observer's observation behavior, the result of collapse should have been determined before, not affected by the observation.

This can explain many problems without changing the speed of light, but it is contrary to quantum theory.

In quantum magic system, observation is a very important behavior. The particle state of quantum system is determined based on observation, which even exceeds the speed of light and violates the theory of causality.

"Now the problem for the mages is, which side is the explanation in line with the facts, the determinism of objective reality, or the elusive quantum theory."

Lena said helplessly.

"Although I support the latter, I must also propose specific experiments to verify it."
