University of Colorado.

Kalman hadn't had a full night's sleep in a long time.

His desk was piled high with printed drafts of papers, experimental data, and other materials.

There's also a bunch of coffee cups that were finished but not thrown away.

Ever since Lin Yu published his BEC paper, the curtains in his lab have never been drawn.

The light from the computer screen was shining on his face, making his dark circles under his eyes even more noticeable.

"Karl!"

Eric Cornell pushed open the door and came in, clutching a stack of data that had just come out of the printer.

"Failed again."

Lin Yu didn't look up; his eyes were fixed on the posts on the forum by the person with the ID "fromBeiJing" on the screen.

Quantum entanglement-assisted cooling.

The quadratic scaling law.

The relationship between entanglement entropy and cooling efficiency.

These words swirled in his mind all day; he was practically obsessed.

"How many times has this happened?"

Wyman asked Carnell, his voice hoarse beyond belief.

Since the paper was published, he has been trying to replicate it.

"Seventeen times!"

Connor slammed the data onto the table.

He crouched on the ground, holding his head in his hands.

"The equipment they used in their published papers was really outdated."

"Our instruments can never quickly replicate their theories."

"Each time it's either a little too much or a little too slow."

"If we were to build it from scratch using their equipment, it would take a very long time."

"It's a bit better today since I've been using what FromBeiJing said."

"That's simply impossible!"

Cornell was having a hard time.

Calviman said that there were Chinese people sharing technology on the forum, but he didn't believe it.

This isn't something you can just find anyone to share on a forum.

He can even name himself Frommars, so he can't be a Martian.

The result was completely unexpected.

I used the technology shared by that person on this forum.

However, it still couldn't be done successfully, but it was clearly more suitable for the instruments they were currently using.

Lin Yu probably never imagined that the theory he made up on the spot would actually be somewhat useful, but even if he knew, he wouldn't care.

This thing can never be made real if it's fake.

For a time, the data looked good, but in reality, it was far from accurate.

Even the slightest difference is an insurmountable chasm.

"Following what fromBeiJing said, we adjusted the magnetic field gradient to these parameters and locked the laser frequency."

"Yes, the vacuum level meets the standard."

"But BEC just won't appear, that damn phenomenon just won't show up."

Cornell was somewhat taken aback. Could this really be something a human could create?

How did these Chinese people manage to measure BEC with those rudimentary instruments?!

When Cornell broke down, he found a table, squatted down, and started dancing.

Viman finally raised his head.

He rubbed his red eyes and asked, "Do you think we might have misunderstood?"

"What did you misunderstand?"

"That quadratic scaling law."

Wiemann stood up and walked to the blackboard, which was covered with densely written derivations, but they were all useless.

Now he erased part of it and wrote some more on it.

"You see, according to FromBeijing, there is a quadratic relationship between entanglement entropy and cooling efficiency."

"But what if the entanglement itself also decays during the cooling process?"

"We never considered this possibility!"

Cornell paused in his dancing upon hearing this, then slipped and fell: "You mean, the cooldown effect of Entanglement is negated by Entanglement decay?"

"right!"

Wyman's eyes lit up: "That explains why we have more atoms than the Chinese, yet our temperature can't drop!"

"Because we didn't consider the entanglement and decoherence!"

Cornell was even more speechless when he heard this. Wouldn't that mean they were useless?

"Then we need to redesign the entire experimental protocol—"

"If we could design the experimental plan, would we have let the Chinese beat us to it?"

Wyman shook his head, picked up the chalk, and, ignoring the already insane Cornell, drew a complex diagram on the blackboard.

"more than"

"We also need to add an entanglement maintenance system to the magneto-optical trap."

"Use an optical cavity or a microwave field; in short, the entangled state must be maintained during the cooling process."

"Following the guidance in this post, we can definitely build a new direction!"

"The Chinese were the first to achieve BEC, but we can come up with new methods to achieve BEC!"

Cornell jumped off the table, nearly twisting his ankle, but he didn't pay much attention.

He ran up to the blackboard, then stared at the diagram for a full five minutes before suddenly slapping his thigh and exclaiming, "Karl, you're a fucking genius!"

"I'm not a genius."

Wyman chuckled strangely: "It's that FromBeijing guy. He hid the key information in those posts, but now..."

"They're ours!"

He sat back down at his computer and refreshed the forum page.

He's been waiting here all day.

That despicable FromBeijing posted and then disappeared.

He had a lot of questions he wanted to ask.

But no one could answer that.

Just then, he clicked refresh.

FromBeijing posted a new thread.

[Some initial thoughts on entanglement maintenance in BEC experiments]

I saw this title.

Viman's hands trembled with excitement, and the mouse cursor flew erratically across the screen. He could only click on it after he calmed down.

The post is short, but it contains a lot of information.

"Based on our team's recent experimental findings, we have discovered that if a microwave field of a specific frequency can be applied to the central region of the magnetic trap during the evaporative cooling process, the lifetime of the entangled state can be significantly extended."

"In terms of frequency, we recommend using the hyperfine level splitting frequency of rubidium 87, which is approximately 6.8 GHz."

"The empirical formula for field strength that we derived is: B mw = 0.5 * (Δf)^{1/2}, where Δf is the RF evaporation cooling voltage."

However, the frequency scanning range.

"In addition, we found that in the compression magnetic trap stage, if a non-adiabatic compression method is used, the density can be increased by about 30% without heating the atoms."

"For the specific compression curve, we fitted a function: B(t) = B0*(1 + αt)^{β}, α≈2.3, β≈1.7."

"Finally, a friendly reminder: throughout the entire process, the vacuum level must be maintained below 5e-12 Torr, otherwise all efforts will be in vain."

When Wyman saw the first line, his eyes widened in surprise.

After watching it, he was so stimulated that he leaned back in his chair, as if he had suddenly received a large amount of dopamine.

Seeing him like this, Cornell quickly came over.

His eyes widened as he stared at the screen: "This—they just gave us the experimental protocol directly?"

"almost."

Wiemann murmured, "The microwave field maintains the entanglement, the non-adiabatic compression, and that vacuum level—each of these is something we hadn't considered before."

of. "

"Then what are you waiting for? Let's try it!"

"etc!"

Wyman stopped him, pointing to the bottom right corner of the screen and saying, "Look at this."

Cornell leaned closer and saw a small line of text at the end of FromBeijing's post: "PS: The above content is based on theoretical derivation and has not been experimentally verified. Any resemblance to actual events is purely coincidental."

'

There aren't many people doing fancy tricks on the internet right now.

This was the first time they had ever seen such a statement.

I found it both novel and interesting.

The two exchanged a glance.

Cornell scratched his head: "This is—a disclaimer?"

"Whether it's a disclaimer or not, it's the most specific guidance we've received in a long time. It's better than blind luck."

"That?"

"try!"

Wyman stood up: "Tell everyone, we're working overtime tonight. Redesign the experimental protocol, just like FromBeijing suggested!"

"This might be a discarded design of theirs!"

"But now it's ours!"

"Let's show this proud Chinese man that we can steal their victory!"

Meanwhile, in Beijing, across the ocean...

In the basement of Beihang University, Lin Yu leaned back in his chair, staring at the post that had just been published on the screen, laughing so hard he almost fell over.

It looks just like a fox that has stolen a chicken.

"6.8GHz microwave field, non-adiabatic compression curve, vacuum degree of 5e-12 ————"

He kept repeating the parameters he had programmed, and the more he repeated them, the more he wanted to laugh.

He was somewhat impressed with his own ability to fabricate stories.

As soon as he got his hands on the internet, he went back to his comfort zone.

In the past, there was absolutely no opportunity to use deception.

Now, even through a screen, he can use the internet to manipulate the United States.

Are the things he said useful?

Yes, but not completely.

Microwave fields can indeed affect atomic states, but they have absolutely nothing to do with maintaining entanglement.

Trying to achieve quantum entanglement through such a shortcut is a sure way to fail.

But in practice, it looks quite convincing.

Non-adiabatic compression can indeed increase density, but Lin Yu didn't mention that if this isn't controlled properly, it can heat the atoms.

These are things that were discovered little by little by later generations through trial and error.

Very few labs know this now.

Those who know about it keep it a secret like a treasure.

Those who don't know will only gain false wisdom from listening to this.

As for that vacuum level...

5e-12 Torr is indeed an order of magnitude higher than the one they used in their experiments.

But this is the limit that the old equipment at the Institute of Physics, Chinese Academy of Sciences, can achieve; any new equipment from abroad can easily reach the same level.

The problem is that it's difficult to downgrade such good equipment!

Lin Yu combined these elements together, and with the premise of maintaining entanglement, a perfect closed loop was formed.

If Wiemann and his team believed in this theory and followed this plan—

Lin Yu closed his eyes and mentally simulated the entire process.

I also used artificial intelligence to search for experimental equipment in the United States during that era.

Then Kukukuku laughed.

First, it would take them at least a week to modify the experimental setup—adding a microwave generator and the corresponding control system.

Then, they would adjust the magnetic field according to the compression curve he provided.

This curve was generated by him on the computer using a random function, and it is theoretically completely self-consistent!

Lin Yu never fabricates anything that's easy to verify!

If you're going to build something, you have to make it realistic!

Only realism can truly make you feel good.

But as for the actual effect—who knows?

Then, they will pump the vacuum to 5e-12 and begin a new round of evaporative cooling.

What will the result be?

If they're lucky, Carl Wiemann and his team might see some unusual signals.

Because microwave fields do indeed affect the spin state of atoms, but that signal is definitely not BEC.

If they're unlucky and don't see anything unusual, they'll start to suspect that something is wrong with their actions.

In either case, they will continue down this wrong path, going further and further astray.

When they realized something was wrong and went back to look at Lin Yu's post...

You'll find that FromBeijing's posts are incredibly professional.

Every parameter has a theoretical basis, every suggestion is supported by a formula, and a disclaimer is thoughtfully added at the end.

They are the only ones who are wrong.

perfect!

Lin Yu became happier and happier as he thought about it; Calviman had even gone online with his real name.

He can't resist trying to scam people.

So he casually typed another reply: "Dr. Wieman, I suggest you focus your research on phase modulation of microwave fields!"

"We found that at a specific modulation frequency, the entanglement maintenance efficiency can be improved by about 15%."

"The specific parameters are still being optimized. We will share the results once we have them."

After posting this, he closed the American forum with satisfaction and opened another window.

This is a domestic technology forum. It hasn't been open for long and there aren't many people, but they are all experts in their respective fields.

Lin Yu hadn't expected there to be so many experts on internet addiction.

Even if only universities have internet access in the early morning.

There are now a lot of people here having a lively discussion.

Lin Yu's ID here is BJ—Young.

Because the domestic website wasn't well-developed, even though it's a domestic technical forum, communication was still limited to English.

He came from the future, but he knew that the most important rule for going online was not to use one's real name.

Otherwise, someone will open the box sooner or later.

I wonder when I'll be attacked by the boomerang-like force of my own words.

Lin Yu casually flipped through the posts and came across one discussing aviation fuel.

These people weren't as cautious as him; they not only wrote their names but also the abbreviation of their organizations.

The post was made by someone from Sinopec, and it asked about the corrosiveness of ethanol gasoline.

Lin Yu has already covered this in a previous lecture, so I don't recommend going over it again now.

Lin Yu thought for a moment and typed a line: "I suggest adding a small amount of corrosion inhibitor to the ethanol, mainly composed of benzotriazole and modified fatty acids, in a ratio of approximately 0."

1%–0.3%.

"In addition, the inner wall of the fuel tank can be passivated by soaking it in phosphoric acid or oxalic acid solution to form a phosphate protective film."

After posting this, he switched back to the American forum for a quick look.

Viman has already replied: "FromBeijing, thank you very much for sharing."

"We are redesigning the experimental protocol and expect to begin a new round of testing in a week."

"We will report the results to you at that time."

"Also: Regarding the phase modulation you mentioned, could you provide some specific parameters? For example, the range of modulation frequency, modulation depth, etc."

Lin Yu's smile widened as he read the reply.

This white guy writes forum posts with the tone of an email.

Professor Wieman, oh Professor Wieman...

You've taken the bait completely.

Lin Yu typed another line: "Dr. Wieman, we are still optimizing the specific parameters of phase modulation, and it is not convenient to disclose them at the moment."

"But here's a tip: consider using sawtooth wave modulation, with a frequency range of 10kHz to 100kHz and a modulation depth between 0.1 and 0.5."

"This range was determined by our scan. The optimal value varies depending on the device, and you will need to figure it out yourself."
