Perhaps knowing that his request was a bit embarrassing, as soon as Director Li said these words, his voice became softer and quieter unconsciously.
Lu Zhou thought for a while and spoke.
"I'll give Chen Yushan a call later," Lu Zhou thought for a while and said, "It's the same thing if she goes."
A more friendly solution is to add a repeater at a certain distance to amplify the attenuated signal and continue sending it, just like traditional communication methods.
[Three-dimensional quantum memory]
The difficulties of quantum repeaters can be divided into three parts, entanglement exchange, entanglement purification, and quantum storage.
"What does science mean to you?"
The first two are easy to say, but as for the last one, it is basically a problem in the same dimension as quantum computers.
It wasn't until the minute hand passed a big mark that he suddenly thought of something and spoke.
However, turning down the volume didn't make this embarrassing request sound more tactful, so he ended up getting a look from Lu Zhou.
Upon hearing this expected answer, Lu Zhou sighed softly.
Therefore, the key to the problem is how to solve the bottleneck of quantum repeaters.
By then, he wouldn't have to put in much effort or waste precious points, and he would be able to obtain the quantum memory technology he expected naturally.
"What I just said was to tell you the key to solving the problem, not for you to continue asking me how to solve the problem!"
"Isn't the meeting at three o'clock okay?"
"If this entanglement is destroyed at any time, such as collapse due to observation, then the device can no longer function as a quantum memory, but transforms into an 'entanglement-disrupted channel' that can only transmit classical information."
Lu Zhou thought for a while and spoke.
By then, he wouldn't have to put in much effort or waste precious points, and he would be able to obtain the quantum memory technology he expected naturally.
"What's up?"
However, in the face of Lu Zhou's complaints, Director Li not only showed no intention of introspection, but continued shamelessly.
Wang Peng looked at the car interior mirror and asked.
The first two are easy to say, but as for the last one, it is basically a problem in the same dimension as quantum computers.
"Well... you have found the problem anyway, why not just solve it?"
"The quantum entanglement between the system stored in memory and any remote system not in memory must be maintained throughout the storage time..."
Wang Peng was used to Lu Zhou occasionally asking him some strange questions.
A more friendly solution is to add a repeater at a certain distance to amplify the attenuated signal and continue sending it, just like traditional communication methods.
Looking at the embarrassed smile on Director Li's face, Lu Zhou couldn't help but have an illusion.
In terms of security, the latter is naturally unparalleled, but the price is that the technology is quite difficult, so difficult that it has no friends. The academic community gave up on it around 2007.
In the current era of information globalization, it is impossible for any country to break away from the Internet, and what Director Li expects is obviously not a technology that can only be played behind closed doors.
He finally dismissed Director Li with the words "I'll think about it when I have time." Seeing that the time was almost up, Lu Zhou called Wang Peng and then went straight to the parking lot.
Looking at the embarrassed smile on Director Li's face, Lu Zhou couldn't help but have an illusion.
Does this guy think of himself as Tinkerbell
"Isn't the meeting at three o'clock okay?"
By then, he wouldn't have to put in much effort or waste precious points, and he would be able to obtain the quantum memory technology he expected naturally.
No, it might not be an illusion.
…
However, when the scope of communication expands to a global scale, the security of overseas sites cannot be guaranteed to be 100% trustworthy, and the security of trusted relays needs to be discussed.
With that said, Lu Zhou motioned to Xiao Ai to evacuate the inert gas in the transparent container, unlock the code lock, put on special gloves and take out the well-preserved carbon-based integrated circuit board from inside.
"What does science mean to you?"
This is what eight achievements look like...
"So this is the biggest misunderstanding of science."
"I originally planned to study this topic after completing the Earth-Moon Control Project."
"I think that should be the way to solve the problem, which is probably similar to-"
Does this guy think of himself as Tinkerbell
"It's a bit difficult..."
"What's up?"
Looking at the seven neat characters on the paper, Lu Zhou nodded with satisfaction.
"What's up?"
…
After thinking seriously for a while, he spoke.
"I think that should be the way to solve the problem, which is probably similar to-"

"That's okay, let's try it first and then talk about it."
Looking at the integrated circuit board lying on the experimental equipment, Lu Zhou pondered for a long time.
"That's okay, let's try it first and then talk about it."
"I don't seem to be an ordinary person."
After sitting in a black car and watching Wang Peng turn the steering wheel and drive the car onto the highway, Lu Zhou, who was sitting in the back seat, suddenly spoke.
In his original idea, as quantum computer technology breaks through and is widely used in commercial fields, capital will naturally push quantum memory technology forward in order to build faster and more powerful quantum computers.
The latter is based on quantum entanglement distribution technology to establish shared entanglement pairs between adjacent sites, store the entangled pairs using quantum storage technology, and apply entanglement conversion operations to achieve shared entanglement between adjacent sites.
"If this entanglement is destroyed at any time, such as collapse due to observation, then the device can no longer function as a quantum memory, but transforms into an 'entanglement-disrupted channel' that can only transmit classical information."
Wang Peng looked at the car interior mirror and asked.
"Roughly the same."
"Isn't the meeting at three o'clock okay?"
"I think that should be the way to solve the problem, which is probably similar to-"
"Wang Peng."
"Well... you have found the problem anyway, why not just solve it?"

"What's up?"
After arriving at the Jinling Institute for Advanced Study, Lu Zhou made a phone call to Chen Yushan and entrusted her with the afternoon meeting. He also edited an email and sent the meeting outline to her mailbox.
"Wang Peng."
Looking at the seven neat characters on the paper, Lu Zhou nodded with satisfaction.
"It's a bit difficult..."

Wang Peng was used to Lu Zhou occasionally asking him some strange questions.
"What does science mean to you?"
Objectively speaking, if it is only communication within the country, such as a dedicated military-industrial line, it is completely sufficient to use a trusted relay. Just like the "Beijing-Shanghai Main Line" and the Mozi, under the protection of the people's army, it is impossible to say that the workstation is "occupied".
Wang Peng was used to Lu Zhou occasionally asking him some strange questions.
Xiao Ai: [(?·▽·)]
"but… "
In other words, if this technical route is adopted, unconditional security is based on the premise that "the workstation is trustworthy".
No, it might not be an illusion.
"What's up?"
After thinking seriously for a while, he spoke.
There are currently two types of relay technologies, one is trusted relay and the other is quantum relay.
In the current era of information globalization, it is impossible for any country to break away from the Internet, and what Director Li expects is obviously not a technology that can only be played behind closed doors.
Muttering to himself, Lu Zhou, who was sitting at the experimental table, suddenly picked up a ballpoint pen and wrote a line of words on the scratch paper.
Looking at the integrated circuit board lying on the experimental equipment, Lu Zhou pondered for a long time.
Lu Zhou: "Go to the Jinling Institute for Advanced Study."
"but… "
Lu Zhou: "Go to the Jinling Institute for Advanced Study."

After arriving at the Jinling Institute for Advanced Study, Lu Zhou made a phone call to Chen Yushan and entrusted her with the afternoon meeting. He also edited an email and sent the meeting outline to her mailbox.
Wang Peng: "...?"
In fact, more than 80% of the reasons why Lu Zhou has not researched quantum memory technology for the time being is due to this factor.
It wasn't until the minute hand passed a big mark that he suddenly thought of something and spoke.
"Similar to making water burn, making air solidify, making steel fly...is this what you mean?"
"What does science mean to you?"
"I think that should be the way to solve the problem, which is probably similar to-"
In terms of security, the latter is naturally unparalleled, but the price is that the technology is quite difficult, so difficult that it has no friends. The academic community gave up on it around 2007.

"Isn't the meeting at three o'clock okay?"
But what’s interesting is that the research on quantum memory and quantum computers overlap to some extent. The only difference is that quantum memory is almost essential for long-distance quantum communication, but it is not strictly necessary for quantum computers.
[Three-dimensional quantum memory]
"Roughly the same."
Lu Zhou: "Go to the Jinling Institute for Advanced Study."

Upon hearing this expected answer, Lu Zhou sighed softly.
However, turning down the volume didn't make this embarrassing request sound more tactful, so he ended up getting a look from Lu Zhou.
The meeting mainly discussed the work arrangements for the Lunar Surface Mass Accelerator project. As he had already arranged the work in advance, he did not necessarily have to appear in person.
"So this is the biggest misunderstanding of science."
"This is not a subject that can be completed by one person."

Wang Peng: "...?"
Arriving at the underground research institute, Lu Zhou walked to the laboratory where he had studied carbon-based quantum processor chips some time ago. He looked at the carbon-based integrated circuit board encapsulated in a transparent container and said to himself.
By then, he wouldn't have to put in much effort or waste precious points, and he would be able to obtain the quantum memory technology he expected naturally.

"Well... you have found the problem anyway, why not just solve it?"
"This is not a subject that can be completed by one person."
The former is similar to key relay, allowing keys to be passed between trusted workstations. Compared with the latter, the technical difficulty is slightly lower, but the problem is that once the relay station is controlled by hostile forces, there is the possibility of eavesdropping.
Wang Peng looked at the car interior mirror and asked.
If there is, a more advanced quantum computer can be built. If not, there are less advanced quantum computers to choose from... which is the one he DIYed.
With that said, Lu Zhou motioned to Xiao Ai to evacuate the inert gas in the transparent container, unlock the code lock, put on special gloves and take out the well-preserved carbon-based integrated circuit board from inside.
In contrast, there are more important things waiting for him to do.

"What's up?"
"Isn't the meeting at three o'clock okay?"
In fact, more than 80% of the reasons why Lu Zhou has not researched quantum memory technology for the time being is due to this factor.
Due to the interaction between the quantum communication system and the channel, the coherence attenuation of the pure state in the system will be caused, thereby increasing the randomness of the internal phase difference of each superposition component, leading to the failure of quantum information transmission.

"I'll give Chen Yushan a call later," Lu Zhou thought for a while and said, "It's the same thing if she goes."

However, this method sounds easy, but for quantum communication methods, it is extremely difficult. Because quantum communication is mainly based on the quantum effects of single photon spin states, amplifying optical devices will destroy qubits.

Due to the interaction between the quantum communication system and the channel, the coherence attenuation of the pure state in the system will be caused, thereby increasing the randomness of the internal phase difference of each superposition component, leading to the failure of quantum information transmission.
"So this is the biggest misunderstanding of science."
"If this entanglement is destroyed at any time, such as collapse due to observation, then the device can no longer function as a quantum memory, but transforms into an 'entanglement-disrupted channel' that can only transmit classical information."
Does this guy think of himself as Tinkerbell
The first two are easy to say, but as for the last one, it is basically a problem in the same dimension as quantum computers.
However, when the scope of communication expands to a global scale, the security of overseas sites cannot be guaranteed to be 100% trustworthy, and the security of trusted relays needs to be discussed.
However, turning down the volume didn't make this embarrassing request sound more tactful, so he ended up getting a look from Lu Zhou.
…
Wang Peng thought for a while. Although he felt that this statement was a bit abstract, he felt that there was nothing wrong with it, so he nodded.
Looking at the embarrassed smile on Director Li's face, Lu Zhou couldn't help but have an illusion.
"It's a bit difficult..."
A more friendly solution is to add a repeater at a certain distance to amplify the attenuated signal and continue sending it, just like traditional communication methods.

Lu Zhou: "Go to the Jinling Institute for Advanced Study."
Arriving at the underground research institute, Lu Zhou walked to the laboratory where he had studied carbon-based quantum processor chips some time ago. He looked at the carbon-based integrated circuit board encapsulated in a transparent container and said to himself.
"I originally planned to study this topic after completing the Earth-Moon Control Project."
"If this entanglement is destroyed at any time, such as collapse due to observation, then the device can no longer function as a quantum memory, but transforms into an 'entanglement-disrupted channel' that can only transmit classical information."
"It's a bit difficult..."
In contrast, there are more important things waiting for him to do.
Looking at the integrated circuit board lying on the experimental equipment, Lu Zhou pondered for a long time.
"Isn't the meeting at three o'clock okay?"
"It's a bit difficult..."
It wasn't until the minute hand passed a big mark that he suddenly thought of something and spoke.
"I'll give Chen Yushan a call later," Lu Zhou thought for a while and said, "It's the same thing if she goes."
The former is similar to key relay, allowing keys to be passed between trusted workstations. Compared with the latter, the technical difficulty is slightly lower, but the problem is that once the relay station is controlled by hostile forces, there is the possibility of eavesdropping.

However, this method sounds easy, but for quantum communication methods, it is extremely difficult. Because quantum communication is mainly based on the quantum effects of single photon spin states, amplifying optical devices will destroy qubits.
"Let's call it this name for now!"
"This is not a subject that can be completed by one person."

In fact, more than 80% of the reasons why Lu Zhou has not researched quantum memory technology for the time being is due to this factor.
"Wang Peng."
The former is similar to key relay, allowing keys to be passed between trusted workstations. Compared with the latter, the technical difficulty is slightly lower, but the problem is that once the relay station is controlled by hostile forces, there is the possibility of eavesdropping.
After sitting in a black car and watching Wang Peng turn the steering wheel and drive the car onto the highway, Lu Zhou, who was sitting in the back seat, suddenly spoke.
In other words, if this technical route is adopted, unconditional security is based on the premise that "the workstation is trustworthy".
In his original idea, as quantum computer technology breaks through and is widely used in commercial fields, capital will naturally push quantum memory technology forward in order to build faster and more powerful quantum computers.
Upon hearing this expected answer, Lu Zhou sighed softly.
"but… "
No, it might not be an illusion.
"I think that should be the way to solve the problem, which is probably similar to-"
Looking at the embarrassed smile on Director Li's face, Lu Zhou couldn't help but have an illusion.
"Wang Peng."
The difficulties of quantum repeaters can be divided into three parts, entanglement exchange, entanglement purification, and quantum storage.
The latter is based on quantum entanglement distribution technology to establish shared entanglement pairs between adjacent sites, store the entangled pairs using quantum storage technology, and apply entanglement conversion operations to achieve shared entanglement between adjacent sites.
Upon hearing this expected answer, Lu Zhou sighed softly.
If there is, a more advanced quantum computer can be built. If not, there are less advanced quantum computers to choose from... which is the one he DIYed.
"I don't seem to be an ordinary person."
…
"What's up?"
After arriving at the Jinling Institute for Advanced Study, Lu Zhou made a phone call to Chen Yushan and entrusted her with the afternoon meeting. He also edited an email and sent the meeting outline to her mailbox.
However, this method sounds easy, but for quantum communication methods, it is extremely difficult. Because quantum communication is mainly based on the quantum effects of single photon spin states, amplifying optical devices will destroy qubits.
"Well... you have found the problem anyway, why not just solve it?"
"but… "
With that said, Lu Zhou motioned to Xiao Ai to evacuate the inert gas in the transparent container, unlock the code lock, put on special gloves and take out the well-preserved carbon-based integrated circuit board from inside.
But what’s interesting is that the research on quantum memory and quantum computers overlap to some extent. The only difference is that quantum memory is almost essential for long-distance quantum communication, but it is not strictly necessary for quantum computers.
Xiao Ai: [(?·▽·)]

"Similar to making water burn, making air solidify, making steel fly...is this what you mean?"
He finally dismissed Director Li with the words "I'll think about it when I have time." Seeing that the time was almost up, Lu Zhou called Wang Peng and then went straight to the parking lot.
Muttering to himself, Lu Zhou, who was sitting at the experimental table, suddenly picked up a ballpoint pen and wrote a line of words on the scratch paper.

However, in the face of Lu Zhou's complaints, Director Li not only showed no intention of introspection, but continued shamelessly.
[Three-dimensional quantum memory]

After sitting in a black car and watching Wang Peng turn the steering wheel and drive the car onto the highway, Lu Zhou, who was sitting in the back seat, suddenly spoke.
Looking at the seven neat characters on the paper, Lu Zhou nodded with satisfaction.
A more friendly solution is to add a repeater at a certain distance to amplify the attenuated signal and continue sending it, just like traditional communication methods.

"Isn't the meeting at three o'clock okay?"
Therefore, the key to the problem is how to solve the bottleneck of quantum repeaters.
"Let's call it this name for now!"
"I don't seem to be an ordinary person."
