What to do?

Oops,

What a headache!

"well?"

"When did you come back?" Yang Xiaoman walked out of the room and saw Xu Mang lying on the sofa with a tired look on his face. He asked curiously: "What happened? Did the second grandpa arrest you again?"

Are you a grown man?"

"No."

"I caught a researcher from the International Nuclear Fusion Energy Center." Xu Mang said with a smile, "But... I got a chance."

Yang Xiaoman threw herself into Xu Mang's arms, raised her head and looked at him: "What chance?"

"that is..."

"I can't tell clearly. Have you ever been online...do you know about quantum hegemony?" Xu Mang asked.

"I know."

"It's quite popular recently."

"It seems that the Google Quantum AI team released a report through the NASA STI program, using a programmable superconducting processor to achieve quantum hegemony." Yang Xiaoman said: "A quantum chip containing fifty-three qubits, in state

On the spatial random sampling algorithm, it takes about two hundred seconds to execute one million times on one instance."

"In comparison... the most powerful supercomputer currently takes 10,000 years." Yang Xiaoman continued: "Am I right?"

Xu Mang looked at the violent airport in his arms in horror, and asked in surprise: "How do you know it in such detail?"

"snort!"

"I'll also pay attention to real-time, okay?" Yang Xiaoman rolled his eyes and said silently: "You plan to study this? But how do you surpass the two big mountains in front of you, Google and IBM?"

Xu Mang showed a hint of disdain and said calmly: "I don't care about life and death. If you don't accept it, just do it!"

Just when the temperature of the relationship was gradually rising, Xu Mang received a call from Tong Min and the others, telling them that they would treat them to dinner tomorrow night. However, Xu Mang refused. He really didn't have time... and he still had to complete a high-quality paper.

Eating... is unappealing.

night,

Arrive.

Xu Mang is reading this paper from Google. Xu Mang learned from the article that Google has adopted a new packaging technology-flip chip soldering, and this technology makes it possible to arrange qubits in a two-dimensional matrix.

.

This matrix arrangement of neighbor coupling is necessary for surface-encoded quantum error correction.

It’s over!

Flip-chip soldering with this specification...cannot be done!

Xu Mang was confused. The flip-chip welding process is not difficult...the difficulty lies in the accuracy.

Ignoring this problem for the time being, Xu Mang also discovered that the so-called fifty-three qubits actually have a total of 142, of which 88 qubits only work as couplers, and the rest are fully functional.

Qubit usage.

middle...

One was broken.

And relying on the collection of all possible quantum states in a quantum system composed of fifty-three qubits, we can reach the fifty-third power of two... It is simply terrifying!

Turned off Google News,

Xu Mang found a preprint paper published by IBM on arxiv, and then saw IBM's furious attack on Google. In short, in IBM's eyes... Google's quantum supremacy is not a true hegemony.

However, Xu Mang couldn't understand a lot of the content in it. This was a very pure algorithm analysis paper. It probably didn't even have any code written, but it still shattered the dream of quantum supremacy.

But one thing is certain,

Currently, Google and IBM are competing with each other in the world, and no third party has yet been involved.

What's the meaning?

Your American game?

Xu Mang was very unhappy. He decided to start researching tomorrow and be a good troublemaker.
