A few days later.
Inside the main laboratory of the Human Union.
Two enormous machines lay quietly in the center of the laboratory.
Those were two single-photon control devices.
The two machines are of different sizes, one large and one small, with the smaller one being a newly manufactured piece of equipment.
The two devices are connected by a thin conduit.
As for why this situation occurred...
It's very simple.
The purpose of this photon control experiment is to verify whether two entangled photons can transmit information through action at a distance.
Unlike the first experiment, this experiment requires two photons in an entangled state.
Therefore, the second single-photon control device directly eliminated the original single-photon manufacturing equipment.
At that time, both photons will be generated entirely by the first device.
...
Lu Yongchang stood solemnly in front of a machine.
"Professor Lü, may we begin the experiment?"
Tang Wenshan's voice came from the side.
After thinking carefully for a moment and confirming that there were no oversights, Lü Yongchang nodded slightly.
"Let's begin the experiment!"
As he spoke, he reached out and pressed the switch on the enormous machine in front of him.
A slight tremor came from the floor.
The photon manufacturing instrument in the single-photon control device in front of Lü Yongchang began to operate.
As the indicator light turns green, two entangled photons enter the single-photon control devices on the left and right sides through the conduit.
"Zero, first control photon number one."
"Lu Yongchang said in a deep voice."
"Received." The moment Zero's voice rang out, a slight buzzing sound came from the single-photon control device in front of Lü Yongchang.
As for Tang Wenshan, he stared intently at the monitor of another control device, afraid of missing any subtle changes.
"..."
In the laboratory, everyone held their breath.
I was afraid that my faint breathing might affect the two "fragile" photons in the huge instrument in front of me.
Those few seconds felt like an eternity to all the researchers present!
In the silent laboratory, only the faint hum of two single-photon control devices could be heard.
"...It's changed!"
Suddenly, Tang Wenshan's eyes lit up with ecstasy, and he shouted, "The state of Photon Number Two has changed!"
At this moment, even Lü Yongchang could not remain calm.
He followed the group of researchers and ran towards the second single-photon control device.
Looking at the rapidly changing numbers and curves on the screen, Lü Yongchang's face flushed slightly, and he shouted loudly at the camera next to him, "Zero?!"
"Professor, we have conducted 100 state-change experiments so far, and the second photon has produced corresponding changes in all of them."
"Should we continue to change the state of photon number one?"
Lu Yongchang's eyes lit up with even more joy: "Continue, proceed according to the target plan."
"Received. A total of 100,000 experiments will be conducted, with an estimated time of 30 minutes."
Lü Yongchang took a deep breath to suppress his inner elation.
It's not a success yet.
He needs more experimental samples!
...
Half an hour later.
"Professor, the first photon experiment has been completed, with a total of 100,000 state change experiments. The second photon has observed the corresponding changes in all of them."
Zero's voice echoed in the quiet laboratory.
The next second, a burst of enthusiastic applause rang out!
Every researcher had an excited smile on their face.
"Zero, begin the experiment on photon number two!"
In his excitement, Lü Yongchang did not forget to give Ling a second instruction.
...
The second photon control experiment was a complete success, and quantum long-distance communication technology has completed most of its technological accumulation.
Now, the last hurdle to achieving quantum long-distance communication has fallen to Tang Wenshan.
algorithm.
He needs to redesign an algorithm for long-distance communication.
Simply put, he needs to establish a system for the various state changes of photons, much like Morse code.
Only in this way can humans transmit data in real time by changing the state of one or more photons.
"Old Tang, I'm entrusting this arduous task to you."
After the experiment was a success, Lü Yongchang was in high spirits and jokingly said to Tang Wenshan, "You mustn't let this project down!"
Tang Wenshan naturally understood the teasing tone in Lü Yongchang's words. He first glared at Lü Yongchang, who was all smiles, and then laughed heartily and said, "Don't worry."
"With zero help, if I still can't do this task well, then I'm just a wasted academician!"
Lü Yongchang smiled and nodded.
That's right.
With the existence of this strong artificial intelligence, the algorithm problem has become the easiest point to break through in all scientific research projects.
He turned to look at the two massive pieces of equipment, his smile gradually fading, a hint of dissatisfaction appearing in his eyes, as he muttered to himself, "What a pity."
"Um?"
"What a pity?" Tang Wenshan was stunned for a moment, then quickly reached up and rubbed his ears, afraid he had misheard. "What's a pity?"
"Wasn't the experiment going very smoothly?"
Lu Yongchang slowly shook his head: "These two things are too big."
"With other functional components added, the size is estimated to increase several times over."
“This severely limits its application scenarios.” Lu Yongchang frowned and estimated, “Currently, only the Luan Bird series starships can carry this kind of long-range communication equipment.”
"This will likely have a significant impact on future interstellar warfare."
"Next, I may need to scale down this device, but... this task will be quite difficult."
Faced with Lü Yongchang's troubles, Tang Wenshan waved his hand dismissively and said, "These are minor issues."
"Given the current scale of human civilization, it is sufficient to equip the Luan Bird Starship with long-range communication equipment."
"As for lower-class starships, we can use the Luan Bird platform to transmit information."
"Millisecond-level latency is not a big problem for humans nowadays."
"Moreover, we can minimize the delay problem by increasing the number of Luan Bird series starships."
Tang Wenshan's casual remark caught Lü Yongchang's eye.
That makes sense!
As expected of a telecommunications expert, he solved his problem in just a few words!
At that time, simply pairing the Luan Bird Starship and the Xuan Nu Starship together will be enough to solve this problem!
He would call it the "infantry-tank cooperation" of the interstellar era!
"There's another problem." Lu Yongchang's eyes flickered slightly as he continued, "After these few days of experiments, I've discovered a problem."
"Strictly speaking, quantum long-distance communication technology is not a true long-distance communication technology."
