798 The Quantum Eraser Experimen (2/2)

Annick grabbed a cup nervously, trying to calm him down by drinking water. Sprint, on the other hand, held his hands tightly and stuck them to the experiment table before him, not revealing his feelings. They had both guessed which two thought experiments would be done next!

What would the result be like?

After interpreting and demonstrating the double-slit experiment, Lucien said with a smile, ”Next, we are going to transform the experiment to minimize the interferences while keeping the mechanism the same.”

Then, Lucien deployed a new experiment. Through a demonstration, he proved that it was equal to the double-slit experiment just now.

”They're indeed equal. There's no problem at all…” Fernando nodded.

The demigods like Viken and Rudolf II did not have a profound understanding of arcana, but as demigods, it was fairly easy for them to decide whether or not the two experiments were equal.

”Next, we will conduct the quantum eraser experiment, which is a variant of the experiment just now. Just now, you must've seen that when the two 'alarms' next to the slits recorded the electrons as they passed through the slits and sent out alarms, the interferometric fringes were gone, and the particle properties were manifested.

”Now, we will only make the alarms record but not let them send out any alarms, and they will erase the records immediately after they record the information. What will we see then? Will the interferometric fringes be gone?”

Lucien lucidly explained the mechanism of the experiment instead of the real experiment process.

”Of course, the interferometric fringes will be gone, and the particle properties will be revealed. It's essentially the same as the previous experiment. The only difference is that we cannot know which slit the electrons used to pass through the alarms now, but can our knowledge affect the experiment result at all?” Having studied the basics of arcana for years, Longman had a few guesses about the experiment, which seemed rather ”simple”.

The ordinary students like Ali and Jane and most magic apprentices and arcanists thought the same. The only difference between this experiment and the previous one was whether or not the ”experimenter” knew the trajectory of the electrons. However, whether or not the experimenter knew it shouldn't affect the objectivity of an actual experiment.

Annick did not put down his cup because he had been completely devoted to the experiment. Sprint, Heidi, and the others also held their breath and waited for the result, which would either suggest that the world was normal or prove that the world was so unbelievable and illusionary. Which would it be?

Would it be normal or abnormal?

Viken, Maltimus, and the other demigods were even more solemn because it also concerned their understanding of the world. Did Douglas and Lucien really not know the result?

Douglas walked to the experiment table. He demonstrated the ”erasion” effect with the newly-added experiment devices. After everybody saw it clearly, he chuckled. ”I'm rather curious about the result myself. Let's begin now.”

All the people who watched the live stream held their breath and focused their eyes on the screen, waiting for the result of the experiment.

Douglas activated the experiment. At first, it was the regular procedure, and the interferometric fringes appeared. Then, the quantum eraser experiment was begun.

Would the interferometric fringes disappear, and would the particle features be displayed this time?

The alarms had caused such a result previously!

Time went by one second after another, but the interferometric fringes on the screen were still so clear, so beautiful, and so classic!

The ordinary people like Ali and Longman and most of the magic apprentices and arcanists could barely close their mouths, and they couldn't have looked more hilarious. The only difference between the current experiment and the previous one was whether or not they knew the trajectory of the electrons, but how could their knowledge affect the result of the experiment?

This was too illogical!

There was nothing but quietness in the studio, except for the heavy and hasty breath.

Crack!

The cup in Annick's hands fell on the ground and broke into pieces, and water splashed everywhere. He kept murmuring to himself, ”The observer effect…”

Boom!

Before he knew it, Sprint pushed down the experiment table before him.

Pope Viken seemed to be both delighted and surprised by the result. He said to himself in a low voice, ”The observer effect!”
