I really don't want to lie down and win

"About the matter of quantum computers, in fact, an internal meeting has been held a long time ago, and there are only a few candidates, including Xiao Xu." Director Qin said: "However... his chances of winning are not high, and several other people have Relevant research and development experience, and Xiao Xu is at a disadvantage in this regard."

"So... I asked Xiao Xu to come up with a high-quality paper, so that I can intercede for him." Director Qin glanced at the second grandfather after speaking: "By the way... why didn't I know Xiao Xu before?" Is it your relative?"

The second grandfather smiled helplessly: "Actually... dry relatives."

...

When Xu Mang returned home, he didn't rush to work, put down the bag in his hand, and lay down on the sofa with a relaxed face, thinking about the quantum computer. Director Qin wanted himself to finish a high-quality paper... How to do this?

whoops

Headache!

"Ugh?"

"When did you come back?" Yang Xiaoman walked out of the room, saw Xu Mang lying on the sofa with a tired look on his face, and asked curiously, "What happened? Did Second Grandpa arrest you again as a pawn?" Are you young?"

"No."

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

Yang Xiaoman threw herself into Xu Mang's arms, looked up at him, "What chance?"

"that is..."

"I can't tell. You've been on the Internet... Do you know about quantum supremacy?" Xu Mang asked.

"I know."

"It's been quite hot lately."

"It seems that the Google Quantum AI team released a report through the NASA STI program, using a programmable superconducting processor to achieve quantum supremacy." Yang Xiaoman said: "A quantum chip containing 53 qubits, random in the state space In terms of sampling algorithm, it takes about two hundred seconds to execute one million times for one instance."

"In comparison...the current strongest supercomputer needs 1 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 such details?"

"Humph!"

"My mother, I 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 mountains in front of you, Google and IBM?"

Xu Mang revealed a trace of contempt, and said calmly, "Life and death are not important, if you don't accept it, do it!"

Just when the temperature of the relationship was gradually rising, Xu Mang received a call from Tong Min and the four, telling them to treat them to dinner tomorrow night, but Xu Mang refused. He really didn't have time... and he had to finish a high-quality thesis. Eating...no appeal.

night,

Come.

Xu Mang was reading this article by Google, from which Xu Mang learned that Google had adopted a brand new packaging technology, flip-chip soldering, and this technology made it possible to arrange qubits in a two-dimensional matrix.

And the matrix arrangement form of the nearest neighbor coupling is necessary for surface-encoded quantum error correction.

Finished!

Flip-chip soldering of this specification... no!

Xu Mang looked dazed, the flip-chip soldering process is not difficult... the difficulty lies in the precision.

Leaving aside this issue for the time being, Xu Mang also discovered that the so-called 53 qubits actually had a total of 140, of which 88 qubits were only used as couplers, and the rest were used as full-featured qubits.

middle...

Another one broke.

And relying on the collection of all possible quantum states of the quantum system composed of 53 qubits, the 53rd power of [-] is obtained... It's just terrifying!

Turn off Google News,

Xu Mang found a preprint theory published by IBM on arXiv, and then saw IBM mad at Google. In short, in the eyes of IBM...Google's quantum supremacy is not a real supremacy.

However, Xu Mang basically couldn't understand a lot of content in it. This is a very pure algorithm analysis theory. I guess it didn't even write the code, but it still shattered the dream of quantum supremacy.

But one thing is certain,

Google and IBM are currently competing with each other in the world, and no third party has yet been seen participating.

What do you mean?

Your American game?

Xu Mang was very upset. He decided to start researching tomorrow and be a shit-stirring stick.

Chapter 583 Cruel Reality (2/3)

At the beginning of August,

It's so hot that it's about to collapse. Some boring people are hungry. They go to the supermarket to buy two eggs, find a manhole cover on the road, and cook a poached egg by relying on the temperature of the manhole cover. Xu Mang also saw this strange thing The video, deep in my heart, is just around the corner.

but,

He didn't dare to do this, for fear of being beaten to death by Xiaoman.

"Ugh?"

"By the way, do you have nothing to do recently?" Yang Xiaoman was getting dressed, glanced at Xu Mang who was lying on the bed, and asked curiously: "If you have nothing to do... why don't you stay in my company. "

"Who said that?"

"I'm going to study quantum computers today." Xu Mang said dissatisfiedly, "I'm quite busy."

"cut!"

"Where do you work is not a job." Yang Xiaoman glanced blankly: "You have an office in my company, and I specially arranged it for you. After all, you are the technical consultant director of our company... Speaking of director, what? Time to visit the company?"

Director?

the word...

"Technical consultants are technical consultants, why do you want to add a director behind?" Xu Mang looked at Xiaoman's beautiful plain face and said helplessly: "I go to the company...Will it cause strong reactions? After all, your company has There are quite a lot of female employees, and I have such a handsome..."

Yang Xiaoman: ￣︿￣

So angry!

The idiot really wanted to kill him!
