Technological power starts with upgrading lenses

"Beep——"

As the device beeped, the detection result of A quantum immediately appeared on the screen: spin upward.

Kang Chi then detected the B quantum, and the result showed that the B quantum spin was downward.

This shows that the two quanta have indeed established an entangled relationship.

Next, it is time to verify Kang Chi’s conjecture and the performance of these two entangled quantum traps.

After confirming that both detectors were in the off state, Kangchi re-detected Quantum A.

"Beep——"

A quantum: spin up.

Seeing the same result, Kang Chi's heart sank.

But just like tossing a coin, getting heads two times in a row does not mean it will always be heads.

If it always points upward, it means that the first detection just now has indeed broken the quantum entanglement state, and Kang Chi's conjecture is not true.

Ignoring Quantum B, Kang Chi conducted another detection of Quantum A nervously.

"Beep——"

A quantum: spin down!

Seeing this result, Kang Chi's eyes suddenly widened, and his heart was beating wildly, feeling like it was about to jump into his throat.

Spin down…

Spin down!

It feels like a dead person suddenly comes to life again!

Kang Chi breathed quickly and pressed the B quantum detection switch with a trembling hand.

B quantum: spin upward,

The entangled relationship is still there!

That great academic debate spanned nearly a hundred years and was held at the Fifth Solvay Conference in Brussels in 1927. At this very moment, at the Pangu base in China, new answers and answers emerged. variable!

The idea of ​​answering this question is not whether quantum entanglement exists or not, nor does it depend on whether God throws the dice or not.

But a whole new angle:

God Almighty, why can't you toss the dice more times? !

The answer given by Kangchi is: Yes!

And this almighty God was created by him.

Looking at the two entangled quantum traps in front of him, Kang Chi has no doubt that it will bring unprecedented revolution to the fields of high-energy physics, communications, quantum computers, and even the entire scientific and technological field of human civilization.

Although this revolution in quantum technology may not happen immediately, this day will definitely come.

Kang Chi couldn't help clenching his fists in excitement, and wanted to find someone to talk to and celebrate, but unfortunately he was the only one in the laboratory.

At the same time, out of scientific rigor, he actually needed to conduct multiple experiments repeatedly.

So throughout the morning, the sound of detection kept coming from the laboratory. After a whole morning of demonstration, Kang Chi was very convinced that with the help of this level 5 entangled quantum trap, he had indeed captured a kind of A brand new quantum with “stronger vitality”.

In order to speed up the experiment, Kang Chi directly wrote an automatic continuous detection program, allowing the detector to continuously detect two quanta at a rate of 60 times per second. This experiment should last at least 24 hours to see if the time scale will change. will affect its "activity".

At the same time, Kangchi began to analyze the experimental data, and tried to use these data to prove Bell's inequality using another decomposition idea.

[... Let the angle between α and β be θ. From the rotation transformation of the two-dimensional spinor space in quantum mechanics, it can be known that if the eigenstate |α+\u003e in the α direction is measured in the β direction spin, we get |β+ The probability of \u003e is |β+|α+\u003e|=cos·θ/2. From this we know...]

As time went by, more and more manuscripts were on the table. When Kang Chi's stomach was growling with hunger, he finally breathed out slowly.

[...It is not violated in the {a, b, c, d} directions shown in the figure below, so the inequality ∣Pxz-Pzy∣≤1+Pxy holds. 】

Through experimental data alone, he has determined that hidden variables definitely exist, and proving that Bell's inequality is true is just a necessary summary and analysis.

And the results of calculation and proof were indeed as he expected,

The hidden variable that affects quantum entanglement does exist, but it works in another dimension, so quantum mechanics is indeed incomplete!

But at the same time, Kang Chi frowned slightly.

Although he did prove that Bell's inequality is true by introducing high-dimensional variables,

However, the interval of this high-dimensional variable has very large limitations.

Kang Chi casually found a piece of bread to satisfy his hunger while frowning at the calculations on the table.

After a while, he pulled out another piece of white paper and continued counting.

Soon, he came up with a series of specific numbers: [960875\u003c= x \u003c=999999].

Didi didi——

At the same time, the experimental device suddenly sounded a continuous alarm, and Kang Chi immediately went over to check the situation.

It turns out that just one second before the alarm sounded, the equipment detected the quantum and the result was: A quantum and B quantum, all 60 times were spin down and spin up!

Kang Chi glanced at the number of detections on the screen.

986786.

It happens to be the X interval calculated by Kangchi just now!

After more than four hours and 986,786 consecutive detections, these two quantum quanta were tested 'dead' again!

Or according to Kang Chi's previous thinking, they should be 'jailbroken'...

The restriction of this X variable actually does not lie in the quantum entanglement phenomenon itself, but in the performance of the quantum trap.

It can only conduct 'interrogations' on entangled quanta 960875-999999 times.

This means that although quantum communication chips manufactured using this quantum entanglement phenomenon may achieve super-light instantaneous communication, they have a certain life limit.

This problem is neither big nor small.

Just like memory particles will become damaged if they are read and written too many times, basically all electronic devices must have a lifespan. The only difference is the length of the lifespan and whether the cost of use can be afforded.

Moreover, if the entangled quanta run away, it does not mean that the trap is broken. All you need to do is catch a new pair and bring them back. This means that future quantum communication chips will be like batteries. After use, the quanta must be recharged and returned to the factory. Use special equipment to charge...

The success of this experiment gave Kangchi a clear development idea. However, the specific cost of building such a quantum communication chip and the subsequent use cost are still unknown. If the cost is too high, the problem may be huge.

"Metal element No. 376..."

Kang Chi couldn't help but think of this thing.

The variable of X should be infinite,

Unfortunately, without this element, Kangchi would not be able to upgrade to more powerful quantum capture technology, let alone build a quantum communication chip with a longer service life.

Um,

You can't be too greedy as a person,

With the current results, it is quite explosive and surprising.

Next, Kangchi needs to conduct another test: single quantum communication over long distances.

After all, it is communication technology, so we must separate the two quanta by a certain distance to see if the distance will affect their entangled state, and try to conduct long-distance quantum communication in the true sense.

So Kang Chi quickly used a quantum trap to capture a new pair of quanta, and after briefly measuring it several times to confirm its activity, he picked up his cell phone and dialed Cai Yaobin's number.

"I need two planes, one to Sansha in the South China Sea and one to Mohe in the Northeast."

After hearing this, Cai Yaobin couldn't help but asked with some doubts: "What experiments are you going to do there?"

"One is the most southerly and the other is the most northerly. Of course, we should try to extend the distance as much as possible to conduct communication experiments."

"Damn it, you just got quantum communication!?"

"Not necessarily. Isn't this an experimental verification?"

"Dr. Kang's experiments never fail! You wait in Pangu, I will arrange it immediately!"
