Chapter 419: Do you dare to accept the challenge?
"Could it be... that they have already made an EUV lithography machine?"
"Of course not. EUV lithography machines have just made some breakthroughs, and there is still a long way to go before they can be successfully manufactured."
"It's really strange. We offered to sell them an EUV lithography machine, but they refused decisively. In the end, they didn't even build it. What on earth were they thinking?"
"Wait a minute... Could it be that this is not a chip that is intended 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...could it be used in military equipment?"
"Probably not. Military equipment usually doesn't require chips with particularly high process technology."
Military equipment usually uses a process technology of tens of nanometers, so there is no urgent need for EUV lithography machines. Chip manufacturing can be completed using only DUV lithography machines.
"Keep paying attention to the relevant news, and report any new discoveries in a timely manner."
"Yes, sir."
…
After receiving the detailed information sent by Huang Sibai.
Xu You began to build a suitable chip manufacturing platform for this new type of photonic 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 produce chips that meet the requirements.
With the core chip as support, the "Suanjing" project can continue.
During this period, Xu You, Wang Xiangwu, Han Shubin and others focused their main energy on the "Mathematical Scriptures" project.
Once the project is successful, it will be another great breakthrough in the history of human technological development.
The computing speed of quantum computers will enter a new era.
"Professor Xu, the optimization of the 'Suanjing' chip has been completed. The compatibility between the chip and the system is very high, and the fidelity is above four nines. We can officially start the testing of the 'Suanjing' chip."
"Okay, let's get ready to start the test."
As before, this time the quantum chip testing work also uses the quantum random circuit sampling task as the standard.
In previous tests of the Island quantum computer, it took only 3.06 seconds to complete the quantum random circuit sampling task.
This speed far exceeds all previous programmable quantum computers.
This time, "Suanjing" uses light quanta with faster calculation speed.
If nothing unexpected happens, there will be another major leap in computing speed.
After everything was ready, the test officially began.
With the experience of testing the island quantum computer, Xu You knew that the entire testing process would be very fast.
This is not because the test task is too simple, but because with the development of technology, the computing speed of quantum computers is really too fast.
These tasks, which classical computers would take hundreds of millions of years to complete, can actually be completed in seconds by quantum computers.
"Professor Xu, the calculations have been completed!"
Almost immediately after the test began, the testers announced the completion of the test.
"What's the exact time?"
“3 milliseconds!”
"3... milliseconds?"
Even Xu You did not expect that the test time this time would be measured in milliseconds.
In other words, the calculation speed of "Suanjing" is even a thousand times that of the previous "Haidao"!
"This speed is unimaginable. To say it was just a split second is a bit of an understatement. This short period of time is much shorter than a split second."
Strictly speaking, a moment is 0.36 seconds, or 360 milliseconds.
3 milliseconds, such a short time, is simply imperceptible to humans and can only be measured with professional instruments.
"It seems that in the future, when testing the computing speed of quantum computers, we can no longer use the quantum random circuit sampling task. This task is a bit outdated. Now is the millisecond era, and the next one will be the microsecond era."
If the test is run too quickly, the error can become significant.
In order to more accurately test the computing power of quantum computers, more complex testing tasks are needed.
After several rounds of testing, the performance of the "Suanjing" optical quantum chip was very stable, and the time to complete the task remained at around 3 milliseconds.
After completing the chip testing, "Suanjing" will enter the assembly stage.
Xu You also began to write the corresponding quantum artificial intelligence program for this new optical quantum computer.
…
Just when the "Mathematical Scriptures" project reached a critical stage.
There was a breaking news from across the ocean.
IBM announced that the quantum computer they developed, called "Vulture", has been successfully connected to a supercomputer, achieving faster computing speeds.
In the test of the quantum random circuit sampling task, the enhanced version of "Vulture" completed the calculation of the entire task in just 0.97 seconds.
"Compared to Island's 3.06 seconds, Vulture's 0.97 seconds is not only the first quantum computer to break the one-second barrier, but also three times faster than theirs. In the future, Vulture will lead the development of world science and technology and make more contributions to all mankind. We also look forward to having some friendly computing competitions with Island quantum computers."
The news released by IBM is equivalent to directly declaring war on the island.
Their meaning is very clear . The vulture's computing power has surpassed the island by a level.
This time, they want to avenge their previous shame on Google's behalf.
American netizens are very excited about IBM's latest achievement.
"The calculation speed is three times faster than that of the island! It turns out that we are the real technological overlords! If we have another three-game Go match this time, it should be our turn to give them two pieces, right?"
"This time, I guess they don't dare to take up the challenge. The test of the quantum random circuit sampling task is a very objective test, which basically reflects the computing speed of a quantum computer . Such a gap is like the gap between a college student and an elementary school student. They are not on the same level at all."
"We have finally regained our quantum supremacy! Our computing speed is three times faster than theirs, even though both of them have a 1,000-qubit quantum computer. This proves that we are much better than them in optimizing quantum computers. We should not be too far away from a 10,000-qubit quantum computer."
