Chapter 386 Let’s go inside
"Wait until I'm done with this busy period," this is a phrase Xu You often says.
Lu Zhiyao had also hoped countless times that Xu You would be able to have a good rest after finishing a project.
Not to mention that he had to accompany Lu Zhiyao, at least he had to give his body a good rest.
As a former science student, Lu Zhiyao knows how hard it is to do scientific research.
Lu Zhiyao found the process of learning science alone a bit strenuous.
Not to mention scientific research which is more difficult and intense.
But every time Xu You completes the research on a project, he can almost seamlessly connect to the next scientific research project.
The phrase "wait until I'm done with this busy period" has always been a non-existent concept.
But when Lu Zhiyao thought about these issues from Xu You's perspective, she could understand Xu You's thoughts very well.
Scientific research is Xu You’s hobby, his job, and his responsibility.
Since she has chosen Xu You, Lu Zhiyao must accept everything about Xu You.
After finishing her own pizza, Lu Zhiyao quietly cleaned up the kitchen.
For fear of disturbing Xu You, Lu Zhiyao tried to lower the volume when doing housework.
Of course, all of Lu Zhiyao’s concerns were meaningless.
In the state of deep learning, Xu You could not feel the existence of these sounds at all.
After cleaning up the dining table and kitchen.
Lu Zhiyao gently opened Xu You's door and looked at Xu You from time to time.
Lu Zhiyao didn't want to disturb Xu You, but was worried that Xu You would be alone in the room and something unusual might happen.
Even though Xu You promised not to overload herself with work, Lu Zhiyao was still worried that Xu You would suddenly faint like last time.
Xu You naturally would not make the same mistake easily and always let his brain work within its tolerance range.
Following the direction just now, Xu You was constructing a photonic quantum chip grid structure in his brain.
After multiple construction and simulations in the brain.
Xu You finally found a construction method that can handle different signal functions.
"By designing it this way, we can change the connection status of the internal optical devices by applying external control signals... In this way, we can achieve different signal processing functions!"
When his attention is highly concentrated, the accuracy of Xu You's brain simulation is very high.
After confirming the feasibility of the plan, Xu You quickly copied the design to his computer.
After completing all this work, it was already midnight.
At this time, Lu Zhiyao was already very sleepy, but she was still waiting for Xu You in the living room.
Lu Zhiyao was worried that Xu You would be too tired, but she didn't dare to disturb Xu You casually, for fear of affecting Xu You's work.
"Um?"
Hearing the sound of Xu You's bedroom door opening, Lu Zhiyao suddenly became alert.
"The work is finally done?"
"Well, we're done. Yaoyao, are you still awake?"
"I'm not sleepy yet." Lu Zhiyao replied.
Lu Zhiyao felt somewhat reluctant when she said this, because just now, Lu Zhiyao had been lying on the sofa and almost fell asleep several times.
At this time, Xu You walked towards Lu Zhiyao and picked her up directly.
"Let's go inside and sleep."
…
The next day, Xu You gathered all the project team members of "Photonic Core Valley" and talked about his design results.
"In this design, we use waveguide grids as universal basic units. Through adjustable couplers, we change the connectivity of the waveguide grids to achieve automatic selection of different paths. They can form various optical devices of different sizes to achieve specific signal processing functions. In this way, the flexibility of reconfigurable functions can be further increased..."
Xu You demonstrated his latest waveguide grid design structure of optical quantum chip on the big screen.
Looking at the design drawings on the big screen and listening to Xu You's explanation, all the project team members in the conference room showed extremely shocked expressions.
Such an ingenious design scheme can theoretically enable optical quantum chips to achieve more complex programming tasks.
In the following period of time, the project team entered into the experimental work.
Through the measurement of various data in the experiment, it was proved that Xu You's theory is indeed completely correct.
"Professor Xu, many experiments have proved that our grid structure can indeed achieve the adjustable bandwidth function. By shaping the spectrum of light pulses through microdisk resonators and then mapping wavelength to time through dispersive optical fibers, we can achieve the function of arbitrary waveform generation."
After receiving a positive response from the project team members, Xu You also nodded heavily.
"That's good. The experiment has proven that our structure can support complex programming. Next, we can officially start the design of the photonic quantum chip and prepare for the trial production of the experimental chip."
With a successful basic grid structure, the task of designing photonic quantum chips becomes much less troublesome.
If you want to design chips, EDA is also essential.
With the previous success of Fulon EDA, it is not difficult to develop an EDA for photonic quantum chips.
Based on the original Fulon EDA, Xu You made modifications to some characteristics of photonic quantum chips and developed an EDA specifically for photonic quantum chip design.
Overall, it is simpler than the normal EDA of traditional silicon-based chips.
With the completion of the EDA of the photonic quantum chip, the chip officially entered the design stage.
Luo Wenkun is very concerned about this project and often comes to the laboratory to inquire about its progress.
Every time there is a small breakthrough, Luo Wenkun will be excited for a long time.
Because this means that "Photonic Core Valley" is one step closer to success.
The world chip landscape is no longer so far away from undergoing earth-shaking changes.
With the final design work completed.
The photonic quantum chip has officially entered the trial production stage.
This chip was named "Loongson G1".
Similar to Loongson 001, these two chips are independently designed, developed and produced by us.
The difference is that Loongson G1 is the world's first mobile phone chip that uses photons as information carriers.
Just like last time, this time the chip preparation work still used the domestically produced lithography machine of Modou Microelectronics.
Because the photonic quantum chip does not require high processing accuracy, Modou Microelectronics' 28nm lithography machine is more than enough to complete such work.
The trial production process of Loongson G1 was even smoother than that of Loongson 001.
After completing the trial production of Loongson G1, Fulun Technology began testing this chip.
