Cultivating Immortality Starts with Rubbing a Computer

Chapter 167 Quantum Communication
Carp light inland sea.

Fairy Island.

"Master, I'm leaving now."

Mo Yiyi said, holding a dark box in her hand.

Fang Jun said, "Go ahead. Once you're 500,000 kilometers away, remember to unfold the box as I instructed. Test the entangled state of the particles."

"If you've forgotten, there are detailed steps on the Yuanying. Just follow them and collect data."

Mo Yiyi puffed up her cheeks and said, "Master, I'm not stupid. Why would I need to look at the Nascent Soul for such a simple experiment?"

Fang Jun said calmly, "I'm just trying to avoid any accidents."

"You should know that Master, I occasionally forget some small things and must refer to the data of the Yuanshen."

Mo Yiyi smiled happily when she heard this: "Master, I promise to complete the task."

But after saying this, Mo Yiyi didn't leave, but stood there in a daze for a while.

Fang Jun asked doubtfully, "Yiyi? Is there something wrong?"

Mo Yiyi was puzzled and said, "Nothing. I just had a sudden feeling. Something good and bad is going to happen soon."

Fang Jun heard this and divined the secrets of the universe: "I didn't predict that anything bad would happen."

"On the contrary, good things happened."

Mo Yiyi guessed: "Master, could it be that the experiment will have some mixed results?"

Fang Jun's Tianji and Mo Yiyi are in a superimposed relationship.

Fang Jun's Tianji first chose the direction of the experiment, and Mo Yiyi chose again.

This greatly improves the efficiency of the experiment.

But Mo Yiyi's personal luck is far more powerful than Fang Jun's secret.

Once Fang Jun's destiny conflicts with Mo Yiyi's luck.

It all depends on Mo Yiyi's luck.

Just for the Lord.

This doesn’t mean that Fang Jun won’t make mistakes in experiments.

In fact, even if Mo Yiyi had the choice, Fang Jun would often take the initiative to try those wrong experiments.

Because so-called mistakes do not mean that you will make mistakes all your life.

The data and phenomena it generates itself.

It is also part of the laws of nature.

What you think is a mistake is just that you cannot use it temporarily.

For example, the cosmic microwave background radiation has an unavoidable 3.5K uniform noise.

The malfunction was believed to be caused by pigeon droppings interfering with the antenna.

It was later confirmed to be the afterglow of the Big Bang.

Provided decisive evidence for the Big Bang theory.

Therefore, even if Fang Jun knew it was wrong, he would still do it.

Of course, he won't focus his energy here.

Just do it occasionally to collect experimental data as a reserve.

Who knows when it might come in handy in the future.

Now Fang Jun's destiny and Mo Yiyi's luck are in conflict again.

Fang Jun said: "It may be possible to confirm the entangled state, but it is impossible to confirm which one collapses first."

"Okay, Yiyi, you can go now."

"Remember, tread carefully."

"Don't get involved in any conflicts or disputes you encounter on the road."

"When something happens, the first thing you do is stay away from it."

"Run away immediately if you encounter any possible danger."

"Don't be superstitious about the effect of standing upright without a shadow."

"There are many magical methods in the world of immortal cultivation."

"Maybe I'll just encounter a magical power that can break your shadowless state."

"Don't say you're lucky enough not to encounter it."

"What if? Luck is just a probability after all, not true invincibility."

Mo Yiyi showed no impatience towards Fang Jun's relentless nagging: "Got it, Master. I'll be back soon."

After saying this, he turned into a beam of light and disappeared into the sky.

Fang Jun looked at Mo Yiyi's disappearing figure and silently began to calculate the secrets of heaven.

Until it is confirmed that there are no bad consequences.

Then he breathed a sigh of relief.

Tell the truth, if that's even possible.

Fang Jun didn't mind staying on the island until he had achieved great success in cultivation and then came out.

However, the reality does not allow this.

Not to mention the resources Mo Yiyi used for cultivation.

For example, some experiments must be carried out off the island.

For example, the current quantum entanglement experiment.

Using the methods of the immortal world and his own second-level foundation-building cultivation.

Fang Jun created entangled particles much more easily than in his previous life's laboratory.

It is also possible to rely on materials unique to the world of immortal cultivation to successfully store entangled particles in a certain device.

Of course, this device cannot be put into the storage bag.

Avoid the characteristics of the storage bag from affecting the entangled particles.

So Mo Yiyi was holding it in his hand.

The study of entangled particles is undoubtedly crucial to cracking Mo Yiyi's lucky pattern.

After all, many phenomena show this.

The effectiveness of Mo Yiyi's lucky effect is most likely caused by quantum entanglement.

Fang Jun doesn't have paranoid delusions.

I rarely do things that will cause me to give up my eating because of choking.

It is natural to study it when there is a recent breakthrough, and this breakthrough is quantum communication.

As early as the Yunhai Longmen event, Fang Jun was troubled because his spiritual sense was too strong and Mo Yiyi's was too weak.

This enabled him to easily transmit messages to Mo Yiyi.

However, Mo Yiyi could not send a message to him in order to prevent eavesdropping.

Of course, it’s actually very easy to solve now.

After all, there are computers. You just need to add an extremely complex key, send it through the computer, and then decrypt it.

But the problem is that the world of cultivating immortals has its own secrets.

This thing is similar to an oracle machine.

Even the most complex key can be cracked by it unreasonably.

So is there anything unbreakable?
Of course there are.

That is quantum communication.

The quantum communication here does not use the superluminal effect of quantum entanglement to communicate.

Instead, it uses the measurement collapse effect.

Monks use spiritual consciousness as a means of communication.

Now Fang Jun is basically certain that its essence is still electromagnetic waves carrying information.

The transmitting particles of electromagnetic waves are photons.

Generally speaking, stealing information involves either copying a photon cluster or stealing part of it.

However, quantum communication uses single photons as the carrier for transmitting information.

A single photon is an elementary particle and is indivisible.

This means that once a photon is stolen, the act of eavesdropping will be detected.

The copying of photons is due to the existence of the observed collapse effect.

As a result, whenever one wants to copy a photon, the photon itself will collapse from the superposition state.

Leading to loss of information.

Therefore, quantum communication cannot be eavesdropped.

Of course it does not prevent eavesdropping.

It can only terminate communications if it becomes aware of eavesdropping.

But there is a big problem here, as information is recorded using a single photon, and the information is recorded in a superposition state.

Then how much more technically difficult is it?

Therefore, it is necessary to use quantum entanglement technology.

By using quantum entanglement technology to generate shared keys at any time, and then utilizing the observation collapse effect, we can prevent others from eavesdropping.

This is the difference from traditional communication methods.

In traditional communication methods, the keys are fixed, and even if there are a large number of them, they are limited.

If the other party wants to know the new key.

Then there must be an exchange.

This process may lead to leaks.

However, quantum entanglement can generate keys at all times without any contact.

Once someone eavesdrops.

A collapse will occur and you will know it immediately.

Then change the key immediately.

According to Fang Jun's experiment, divination based on the Way of Heaven's Secrets will also produce collapse.

If not, he would have already confirmed the exact position of the particle through the way of heaven.

All the prerequisites for the above technologies to be realized.

That is, we must have a deep understanding of quantum entanglement and develop various engineering technologies.

What Mo Yiyi is doing now is to verify the technology developed by Fang Jun.

By the way, before verification.

We need to measure whether quantum entanglement really exists.

This is not something that just exists because Fang Jun says it exists, nor is it something that the theory must be like this.

Don’t assume that the world of cultivation exists just because it is so similar to your previous life.

Don't assume that something exists just because the command cards can be broken at the same time.

No falsification experiment was conducted.

It's all theory.

In simple terms, it is fake and does not exist.

So experiments must be done no matter what.

In order to avoid the regionality caused by classical physics, some hidden variables of superluminal speed are implied.

Mo Yiyi had to run as far away as possible to do it.

Even have to transcend the boundaries and go to other realms.

These are the reasons why Fang Jun repeatedly reminded Mo Yiyi.

Because there really is a very small possibility that it could be dangerous.

"It took about a month to go back and forth."

"Because of the barrier of the boundary and the long distance."

“Traditional communication technologies are basically useless.”

"That means I've lost contact with Yi Yi."

"But, with Yiyi's luck, there shouldn't be any problems. If anything goes wrong for me, nothing will happen to her either."

"I'll just wait here for good news."

"Just wait until the agreed time to verify the experiment."

Fang Jun pondered silently in his heart.

He calculated the secrets of heaven again.

Make sure everything is safe.
