Wouldn't it be...they have already made EUV lithography machines?

Of course not. The EUV lithography machine has just made a breakthrough, and there is still a long way to go before it can be successfully manufactured.

It's really strange. They have already offered to sell them an EUV lithography machine, but they refused decisively. As a result, they didn't make it at all. What are they thinking?

Wait a minute... Could it be that this is not a chip that wants to be mass-produced? Or that this chip will not be used in commercial activities?

At this moment, the person on the other end of the communication device seemed to suddenly think of something.

A chip that won't be used in commercial activities...couldn't it be used in military equipment?

Probably not, military equipment usually does not require chips with particularly high process technology.

Military equipment usually uses a process technology of tens of nanometers. There is no urgent demand for EUV lithography machines. Only DUV lithography machines can be used to complete the chip manufacturing.

Continue to pay attention to the relevant news. If there are any new discoveries, we will report in time.

Yes, sir.

...

After getting the detailed information from Huang Sibai.

Xu You began to build a suitable chip manufacturing platform for this new type of optical quantum chip.

After continuous simulation and optimization.

Xu You finally led the team to solve a series of problems such as low refractive index contrast of integrated devices and large device size.

Although the yield rate cannot be guaranteed to be very high, it is enough to manufacture chips that meet the requirements.

With the support of the core chip, the Suanjing project can continue.

During this period of time, Xu You, Wang Xiangwu, Han Shubin and others all put their main energy on the project of Analyses.

Once the project is successful, it will be another great breakthrough in the history of human science and technology development.

The computing speed of quantum computers will enter a new era.

Professor Xu, the optimization of the 'Suanjing' chip has been completed. The chip and the system have a very high degree of adaptation, and the fidelity is above four nines. We can officially start the testing of the 'Suanjing' chip. .”

Okay, then we are ready to start the test.

As before, the quantum chip testing work this time also uses the quantum random circuit sampling task as the standard.

In the previous test of the island quantum computer, it took only 3.06 seconds to complete the quantum random circuit sampling task.

This speed greatly exceeds all previous programmable quantum computers.

But this time, the Suanjing uses light quanta with faster calculation speed.

If nothing else, in terms of computing speed, another major leap will be achieved.

After everything was ready, the test officially started.

With the testing experience of the island quantum computer, Xu You knew that the whole testing process would be very fast.

This is not because the test task is too simple, but with the development of technology, the calculation speed of quantum computers is really too fast.

These tasks that classical computers cannot complete in hundreds of millions of years, quantum computers can actually achieve a real second kill.

Professor Xu, the calculation has been completed!

Almost immediately after the test started, the testers announced the completion of the test.

What is the specific time?

3 milliseconds!

3... milliseconds?

Even Xu You didn't expect that the test time this time was directly measured in milliseconds.

In conversion, the calculation speed of Analysis is even a thousand times faster than that of the previous Sea Island!

This speed is really unimaginable. Saying it is an instant is a bit deprecating. Such a short time is much shorter than an instant.

Strictly speaking, a moment is 0.36 seconds, which is 360 milliseconds.

3 milliseconds, such a short time, cannot be perceived by humans at all, and can only be measured by professional instruments.

It seems that in the future, when testing the computing speed of quantum computers, the quantum random circuit sampling task can no longer be used. This task is already a bit outdated. Now it is the era of milliseconds, and after that it will be the era of microseconds.

If the time required for the test is too short, the error in it can become very large.

In order to be able to test the computing power of quantum computers more accurately, more complex testing tasks are needed.

After several rounds of testing, the performance of the Suan Jing optical quantum chip is very stable, and the time to complete the task has been maintained at about 3 milliseconds.

After completing the testing of the chip, Suan Jing will enter the stage of assembly.

And Xu You also began to write a corresponding quantum artificial intelligence program for this brand new optical quantum computer.

...

Just when the Analysis project reached a critical stage.

From the other side of the ocean, came a heavy news.

IBM announced that the quantum computer they developed called Vulture has been successfully connected with supercomputing to achieve faster calculation speed.

In the test of the quantum random circuit sampling task, the enhanced version of Vulture completed the calculation of all tasks in only 0.97 seconds.

Compared to the island's 3.06 seconds, the vulture's 0.97 seconds is not only the first quantum computer to break through the one-second mark, but also triples their speed. In the future, the vulture will lead the development of technology in the world. All mankind will make more contributions. We also look forward to some friendly computing competitions with the island quantum computer.

The news released by IBM is equivalent to directly declaring war with the island.

What they mean is obvious, the vulture has already surpassed the island in terms of computing power.

This time, they want to replace Google and come to avenge their shame.

Netizens in the United States are very excited about this latest achievement of IBM.

The calculation speed is three times that of the island! Sure enough, we are the real technological overlord! If there is another Go matchup this time, it should be our turn to let them two?

This time, it is estimated that they will not dare to challenge. The test of the quantum random circuit sampling task is a very objective test, which basically reflects the calculation speed of a quantum computer. Such a gap is like a college student and The gap between elementary school students is not on the same level at all.”

We have finally regained our quantum supremacy! With the same quantum computer of one thousand qubits, our calculation speed is three times that of theirs, which proves that we are much better than them in the optimization of quantum computers. It shouldn’t be too far away from a 10,000-bit quantum computer.”
