Chapter 600

In the United States,

the headquarters of Universal Business Machines Corporation,

is the world's largest information technology and business solutions company, usually called IBM. It has a number of heavyweight laboratories, including quantum computer experiments. IBM has a good performance in the field of quantum computing machines.

Different from Google,

IBM puts forward the concept of "quantum advantage". Aiming at real application scenarios, it shows the ability of quantum computing to surpass classical computing. The implication is that quantum advantage should not only reflect the crushing of computing power, but also be useful.

According to IBM's Moore's law of the quantum age, quantum volume will double every year, and quantum advantage is expected to be realized in the 2020's.

IBM defines an index of "quantum volume", which is a parameter related to the number of active quantum bits and error rate. The more quantum bits, the lower the error rate, the larger the quantum volume.

Therefore,

there is a sharp contrast between IBM and Google in the field of quantum computer. The emergence of Google's quantum hegemony only increases the confidence of the scientific and technological circles and the industrial circles. It can not bring real commercial value, because the algorithm used by Google to demonstrate quantum hegemony is meaningless.

However, quantum advantage is striving to realize commercial value. No one can predict when it will come. It is necessary to find a quantum algorithm with practical value and demonstrate it, but it is not easy.

Orkney is the head of IBM quantum computer lab. he just came to his lab, and the next second he was found by his colleagues.

"What?"

"China has developed a chip with 50 qubits?" Orkney looked at his colleagues in horror, and he was greatly shocked, because in the field of quantum computers, China basically has no sense of existence.

"It's all being reported now." The balding middle-aged man said solemnly, "Orkney, look at the news."

For a moment,

Orkney saw the news about China's 50 qubit chips. When he knew it was Xu Mang, he could not describe it with shock.

"This..."

"it's amazing that he came to the field of quantum computers quietly."

"Graphene again? He solved the "coherence time" of graphene qubits? How on earth did this happen? I remember that although graphene has been studied in superconducting quantum computing devices, there are no reports about coherence records... Xu mang has solved this problem? "

"Xu Yang structure?"

"What kind of existence is this?"

Too many doubts filled Orkney's brain, which made him suffocate for a moment.

"Orkney?"

"What should we do now?" The middle-aged man asked, "if the report is true... Then the team led by Xu mang will be on the same ladder with us."

"No

"At present, there is no news report in front of us by the media." "And our 53 qubit quantum cloud computing service is about to be completed, and then in the application field, we will still keep the world" how suddenly... We have launched up to 50 more qubit chips? "

Professor Merck is lost in thought. The team that uploaded an article in arXiv is obviously not Xu mang. This shows that China attaches great importance to quantum computers.

Before that,

Professor Merck didn't worry about being surpassed. After all, in this field, Google and IBM monopolized all relevant technologies, but now it's different... The last person he wanted to meet suddenly broke into the field of quantum computer.

Fifty qubits,

he even got a ticket to "quantum hegemony".

"Damn it!"

"How is this done?" Professor Merck frowned, and through a little bit of content, he knew that Xu mang realized the qubit by using a "Xu Yang structure" relying on graphene, and the content was only here.

At this time,

Professor Merck is very depressed. He has studied the application of graphene in quantum computing devices before, but he and his team cannot solve the problem of time coherence.

However, it never occurred to me that Xu Mang, who came from China, actually solved this problem. He also adopted a method called "Xuyang structure" to directly realize qubits on graphene. What's the situation?

What is Xuyang structure?

At this time,

Professor Merck thought of a terrible thing. It is possible that Xu mang has found a structural form beyond the Josephson junction.

BAM, BAM, BAM, BAM, BAM,

the door of the office was knocked, and for a moment... A young man appeared in front of Professor Merck."Professor!"

"Our foxtail pine chip... Is in a bit of trouble." "In theory, the matrix arrangement of nearest neighbor coupling is a necessary condition for surface coding quantum error correction, but... The packaging technology seems to be limited," the young man said reluctantly

"What?"

"Can't flip soldering work?" Asked Professor Merck in surprise.

"Yes

"We found a lot of problems in welding, mainly in the material..." the young man looked at Merck and carefully said: "we lack a material, although the material structure has been roughly determined through experiments, but..."

pause for a moment,

the young man continued: "but we do not have a very critical adhesive Mixture. "

"Adhesive?"

"What adhesive?" Asked Professor Merck.

"It is... That is..." for a while, the young man did not know how to open his mouth. He organized his language and said, "the photoresist adhesive mastered by Xu Mang of China is lack of this adhesive."

After hearing this, Professor Merck's face turned pale. This adhesive is only controlled by Xu Mang in the world. The price is too high. Moreover, most importantly, he will not sell it to European and American enterprises.

What about this?

The lack of this adhesive means that the foxtail pine chip will fail.

"Professor..."

"will this project be terminated?" The young man asked with a worried face: "this project... We have paid a lot of effort, if it is terminated, it will be greatly affected."

"I'll do something about it." Professor Merck said.

Then,

Merck was left in the office. At this time, he was lost. If he was lucky enough, Xu would sell himself this adhesive, and he would make many unacceptable demands.

It's not that this has not happened. There is still a story about Xu Mang's technical blackmail of refitting STM technology into two.

Technology blackmail...

never expected that a multinational technology enterprise in the United States would encounter technology blackmail.

"Alas..."

Professor Merck sighed and found Professor Smith of Princeton University from the phone book. It was said that Professor Smith and Xu mang had a good relationship. Merck hoped that Professor Smith could communicate with Xu Mang and sell him some adhesive.

Soon,

the call was made.

"Smith, it's me... Merck." Professor Merck said.

"Oh?"

"What can I do for you? Merck. " Asked Smith curiously.

"You..."

"can you contact Xu mang for me "I need his help," Merck said helplessly

After hearing Merck's words, Smith fell into silence. After a long time, he said seriously: "if you are willing to pay a huge price, I can help you to contact Xu mang."
