If you cheat, money will follow

Chang Le was even more confused.

Liu Chaoyang saw it.

He dug into his pocket, took out a coin, and then gave a popular example:

"Boss, look at this coin. If you throw it out, what is the ratio of heads and tails?"

Chang Le said: "If the number of times is unlimited, it should be infinitely close to 50%."

"Yes, the result of quantum computing will also be 50% probability." Liu Chaoyang nodded:

"But here's the problem. Classical calculations will directly tell you the probability of 50%."

"Quantum computing will not tell you the result. It knows it is 50%. But once it tells you, the result is either "1" or "0", not 50%."

Chang Le seemed to understand a little bit:

"I can understand it this way, that is, it can calculate the result, but because of the so-called wave function collapse, it has no way to tell you, and the result will change if it tells you."

Liu Chaoyang nodded: "Yes, it can be understood that way. But this is just one of the problems."

Chang Le said: "What else?"

"Yes, the problem will be bigger next." Liu Chaoyang continued:

“What is the physical basis of quantum computers?”

"Quantum entanglement." Chang Le said.

"Yes, it is quantum entanglement. Quantum entanglement is also called coherence." Liu Chaoyang said:

"However, as long as a group of entangled quanta is disturbed, the other quantum will lose coherence and will no longer be entangled."

"This phenomenon is called decoherence. Decoherence can completely cause a quantum computer to lose its computing power."

"Moreover, this interference includes not only various sounds and vibrations in daily life, but also various weak radiations and weak rays in the universe."

"As long as there is a tiny bit of weak radiation or rays, quantum entanglement will fail."

Chang Le: "..."

Liu Chaoyang continued: "The MIT research project team, in order to avoid interference from the surrounding environment, made a 2-ton lead block into a radiation protection wall;"

"But it still cannot stop the pervasive penetration of cosmic radiation."

"The Stanford research team went even further. They took their equipment and hid 1000 meters underground for research."

"However, these measures are not a permanent solution."

Chang Le said: "This is easy to understand. It means that the rays in the universe hinder the further development of quantum computers."

Liu Chaoyang nodded: "Yes, in order to avoid quantum decoherence caused by cosmic rays, it has become the most critical bottleneck for the further development of current quantum computers."

"Perhaps this is the interference of the Trisolaran civilization on the earth's civilization?"

Liu Chaoyang made a little joke.

"Haha, Dean Liu, do you also read this kind of novel?" Chang Le asked with a smile.

"Look, why don't you read it? Many science fiction novels have scientific theoretical foundations and can bring inspiration to research and development work." Liu Chaoyang nodded and said:

"Researchers in the hospital often watch it too."

"Regarding this decoherence issue, Shu Zhijie is leading a team to study related materials, hoping to find materials that can block the interference of cosmic background rays."

Chang Le asked: "So how did Google solve that quantum computing problem? They have been published in scientific magazines for several consecutive issues."

"They didn't solve it." Liu Chaoyang shook his head:

"On the one hand, what they call a quantum computer is not a complete computer, but a device that uses the principles of quantum mechanics and is specifically designed to solve a single problem."

"On the other hand, in order to overcome the quantum decoherence problem, they will complete the calculation within one thousandth of a millisecond, that is, before the quantum decoherence phenomenon occurs;"

"To overcome the wave function collapse problem, they will prepare a large number of redundant qubits to process information to prevent the qubits from collapsing and losing computing power."

"For example, they simulated the diazene molecule and prepared 53 qubits, but only 12 actually participated in the calculation."

Chang Le thought for a while: "The extra 41 qubits are cannon fodder?"

Liu Chaoyang said: "They are considered cannon fodder. One of them collapses, and then the next one comes."

"Dean Liu, thank you, I learned a lot today." Chang Le said.

"Haha, you're welcome, boss, we can chat more if you have time." Liu Chaoyang said.

"Will do."

No matter how difficult or how big the problem is.

The pace of quantum computing will not stop.

Moore's Law is in a critical period of failure and failure, and classical mechanics has shown signs of withdrawing from the core stage.

Next, the protagonist at center stage will be quantum mechanics.

Quantum mechanics helps human vision extend from the macroscopic to the microscopic.

Achieve detailed exploration and accurate understanding of the underlying operating laws of the microscopic world.

At that time, various counter-intuitive and anti-rule applications will be displayed in front of mankind.

Once humans completely master the microscopic world, will it also be turned into quantum information and travel through space, reaching the North Sea in the morning and the Antarctic in the evening?

Of course, this may just be a distant dream.

It's December.

Bangladesh, Dhaka, peace talks that just entered the 10th day completely collapsed.

Representatives from both sides broke up unhappy and walked away.

As a witness, the representative of Gaul faced the media and said:

Unfortunately, the differences between the two sides are very large, and the possibility of another conflict cannot be ruled out.

autonomous region.

"Everyone, they have no sincerity and do not treat us on an equal footing. In addition to asking us to release the prisoners, they also ask us to withdraw from the Paramita area."

"They are not clear-headed, so we help them wake up."

"Yes, fight! Show their sincerity."

Asan.

Cashman, Hamal and Army Commander Amar walked out of the Assam forward headquarters with gloomy faces.

In the video conference that just ended, their superiors were very dissatisfied with them and severely reprimanded them.

The superiors believe that it is their incompetence and imbecility that have left the country's dignity on the ground and allowed others to trample on it.

At the same time, the superiors also warned the three that if positive results could not be achieved immediately, drastic measures would not be ruled out.

What is a drastic move?

The three of them walked out of the command post.

"It's very simple. During the peace talks, our masters lost their dignity. They want us to help them regain their dignity." Ammar laid out the stakes very directly.

"According to the information we have, the autonomous region has received support from several key equipment that can directly change the course of the war. We are very passive." Cashman was very dissatisfied.

"The gentlemen don't want to know the advanced nature of the other party's equipment, especially those in the parliament." Hammar said:

"They believe that we have received enough support and should obtain corresponding results."

“If we don’t get an acceptable result soon, parliamentary elders will wonder whether all these years of investment have been worthwhile.”

"We should know that the funds are in their hands and they can easily control us."

"I'm curious now, why didn't Kumar and Singh's family members raise their voices?"

"Judging from the current situation, their voices should be muffled." Amar said with a smile.
