I really don't want to lie down and win

After thinking about it,

Xiaoman decided to go back to the room and let him wipe it off.

I told Xu Mang this idea, but Xu Mang rejected it for a simple reason... This is playing with fire, and if you play with fire, you will burn yourself!

night,

In the hotel room, Xu Mang couldn't sleep. He got up silently and took out a pack of cigarettes from his trouser pocket. He stood on the balcony and began to smog. The conductive circuit problem has been stuck for a long time.

How to do?

There is simply no perfect way to solve these problems.

At this time, Xu Mang was in a very embarrassing predicament. He gradually realized that graphene was useless in the field of quantum computers. Although the problem of coherence time was solved and qubits were produced, the quantity was obviously not enough.

period,

Xu Mang tried to change the structure so as to change the service life problem caused by the voltage control, but in the end he failed.

Anyway,

life is so hard...

suddenly,

Xu Mang felt like someone was hugging him, so he knew it was Xiaoman without guessing.

"Thinking about something annoying?" Xiaoman asked gently.

"Ok!"

"The problem with the quantum chip." Xu Mang sighed, and said helplessly, "I've been tortured by this problem...Since I started researching the quantum chip, until now, I've only completed [-]% of it." progress."

"Xiaoman?"

"Am I particularly useless?" Xu Mang smiled wryly.

"No matter what...you will always be the most powerful in my heart." Yang Xiaoman pressed his cheek against Xu Mang's back, and said slowly: "Since I have no clue at the moment, why not let it go for a while and study others."

"talk later..."

"correct."

"There is something I want to discuss with you." Xu Mang said, "I may resign as the deputy director of Fuda's Department of Physics and professor of theoretical physics, and I will directly appoint an honorary professor in the future."

"Ah."

"No matter what you do, I will support you." Yang Xiaoman said.

The two stayed together for a moment,

Yang Xiaoman returned to the room, while Xu Mang was still standing on the balcony, thinking about the problem.

However, Xu Mang found that on the road to realizing quantum computing, he needed to explore all possible ways. Perhaps he should change his thinking and approach from other angles. First, he had to dig deeper into graphene again. Could this thing display quantum chips?

It doesn't have to have four thousand qubits, just a hundred...even fifty.

Difficult!

But Xu Mang understood that what he needed was not panic or fanaticism, but a down-to-earth effort.

...

The next day,

Today will be the last day in the Maldives. According to the plan, he will return home tomorrow. Xu Mang’s schedule for the last day is not very full. He will go shopping in the morning, have a seafood feast at noon, dive and play jet skis in the afternoon, and eat in the evening. Feast.

However, Yang Xiaoman was very dissatisfied with the itinerary. She found that she seemed to be cheated... It felt like she was not accompanying herself, but was accompanying him.

But seeing Xu Mang's expectant look, Yang Xiaoman smiled helplessly.

with myself and with him,

Is there a difference?

at last,

The journey in the Maldives is over, and when they return to Modu International Airport, the two of them will be greeted with endless work, especially Xiaoman... The affairs that have accumulated for several days are waiting for her to deal with, and Xu Mang also Started a new round of research.

Fuda,

In the Condensed Matter Physics Laboratory,

Xu Mang is trying a new structure. He wants to break free from the cage of the Josephson junction and use the new structure mode to offset the problem of reduced service life caused by voltage control.

And the miracle,

is quietly opening the curtain,

A storm is brewing across the world.

......

Chapter 598 Heavy News (2/3)

Condensed Matter Physics Laboratory,

Xu Mang is calculating the constant temperature of a brand new structure, which Xu Mang calls the Xu Yang structure, which has all the properties of a Josephson junction, except that the two are weakly connected to each other, and can also be controlled manually...thus Obtain superconductivity at weakened contacts.

but...

This result is very fragile, requires a constant temperature to work, and ... also requires a signal amplifier, and the voltage control system needs to be on all the time to ensure the limit of the qubit.

But if everything is normal, then the problem of reduced service life caused by voltage control will be perfectly solved.

"..."

"It's over!"

"This temperature...doesn't match the [-]K of the signal amplifier." Xu Mang frowned, lost in thought, building a quantum chip based on Xu Yang's structure, it seems...can't work properly unless the signal amplifier is removed , which means the loss of a large number of qubits.

"never mind..."

"Find a superconducting synchronization device to ensure the continuity of the signal." Xu Mang sighed, and began to retest the quantum chip with a new structure. In the previous three times, the qubits were gradually increased from the original 45, If it still reaches [-] qubits.

Xu Mang's goal was [-] qubits. However, with each upgrade, huge changes were required. From the third to the fourth upgrade, it took about three days.

However, the value of the increase is very small. If this continues...it will take at least 30 years to reach a hundred qubits.
