Chapter 538 Quantum Supremacy! ! !

Although the computing power of supercomputers at this time is already very fast, in order to support the huge and complex virtual world, more powerful computers are bound to be needed, and quantum computers are undoubtedly the best choice!

What is a quantum computer?
Quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information.A cipher that would take a classical computer 100 years to decipher can be done in a second by a quantum computer.

Quantum computers can shorten the running time of some complex problems that classical computers need tens of thousands of years to deal with to a few seconds. It is conceivable how awesome quantum computers are!

In fact, as early as the 20s and 70s, Nobel Prize winner Richard Feynman proposed the concept of quantum computers. After many years of research, this technology has initially achieved results.

There are many companies under Li Zetian's name that have made great achievements in the field of quantum computers, such as Intel, IBM, Microsoft...

Intel is focusing on developing quantum chips.

Microsoft is focusing on developing a programming language for quantum computers.

And IBM is working on developing quantum computers.

At first glance, it seems to be back to when the personal computer was just getting started.

The difference is that these three companies now belong to Li Zetian, and they can cooperate sincerely with each other.

Just yesterday, Li Zetian received a call from Wei Xiuping from Intel. He told Li Zetian that Intel had developed a 49-qubit test chip! ! !
Some people may think that what is so great about a test chip with only 49 qubits? !

But it's just amazing, and Intel even considers it a milestone! ! !
As we all know, traditional computers are binary, that is, only "0" and "1" can be used to record all information states, and each step can only be done by the power of 2 - 2 operations.

The physical structure of a quantum computer is an ordered arrangement of entangled atoms themselves, and quantum bits (qubits) represent state memory and entangled states in the system. A quantum computer with 2 qubits can do 2 to the power of 2 in each step—that is, 4 operations. Therefore, Intel’s chip can reach 2 to the 49th power in one step, which is 562 trillion times.

要知道，目前世界最强的超算神威·太湖之光是每秒9.3亿亿次，而当前世界顶级六核处理器i7-8700K也才约1100亿次，一颗49量子比特的芯片是i7-8700K处理器的多少倍？
Once the 50-qubit chip is conquered, the quantum computer will surpass all existing supercomputers and be able to solve problems that cannot be solved by any computer.When a quantum computer with 300 qubits can support more parallel computing than the number of atoms in the universe! ! !
In 2012, Caltech quantum theorist John Preskill proposed a term - "quantum supremacy", which means that when a quantum computer reaches 50 qubits, its computing power will surpass any computer in the world.

Right now, the 49-qubit chip developed by Intel is only one step away from "quantum supremacy"!
Li Zetian praised the people of the quantum chip development team on the phone, and then told Wei Xiuping to increase investment in quantum chips.

"49 qubits are not enough. I hope that Intel will continue to work hard and develop computers with tens of thousands or even millions of qubits in the next few years!"

Although Li Zetian's request was rather harsh, Wei Xiuping nodded. From a commercial point of view, at least 100 million qubits are required.

Wei Xiuping said in a deep voice: "Yes, Mr. Li, 49 qubits are far from enough, and there is still a long way to go before the commercial goal of quantum computing, but we are confident that we can develop more qubits in a short period of time." bit chip!"

"Yeah." Li Zetian smiled and nodded.As early as two months ago, Intel launched a 17-qubit chip, but it has not been long before a 49-qubit chip was developed.Li Zetian couldn't help but believe that Intel would definitely be able to develop chips with more than 1000 qubits in the next few years! ! !

Breakthroughs in some key technologies often bring about leaps and bounds, from tens or hundreds to thousands, tens of thousands, or even hundreds of thousands.This is the case with changes in the number of transistors on traditional chips. For example, the processor chip developed by Intel Corporation using a 12-nanometer process contains about 80 billion transistors. In the second year, the 7-nanometer process was successfully developed, and the number of chip transistors suddenly increased to 200 billion.

The power of a quantum computer is needless to say, and a powerful quantum chip can make a powerful quantum computer.It can be seen that the quantum chip is simply the ultimate chip! ! !

After hanging up the phone, Li Zetian's heart beat slightly faster when he thought of the future quantum computer.Quantum computers will surely become the engine of the fourth industrial revolution and play a huge role in the fields of artificial intelligence, communication, Internet, and big data.

……

Being the president of the United States is actually not very busy. Many things have to be done by other people. Li Zetian only needs to make the final decision.Bush Jr. took a total of 8 days of vacation during his 879-year presidency, and Li Zetian decided to carry it forward, exceeding 1000 days.

The reason why Li Zetian became the president was for power. Only with power can he cover his own business.Of course he will not work hard to be the president.

At the beginning of September, Li Zetian, Dongfang Yuqin and Yu Jingqiu appeared on the beautiful Hawaiian beach, enjoying life comfortably.The only difference from before is that they brought a "miniature version" of the White House entourage, about 9 people, including White House assistants, secret agents, military staff, communication and transportation experts.In fact, when the president is on vacation, he can do almost anything he can do in the White House.

Li Zetian thought it was good, because staying in the White House was really boring.

After spending a wonderful long vacation in Hawaii, Li Zetian did not return to the White House immediately, but visited China at the invitation of the Chinese leadership.

Immediately, all eyes of the world focused on Li Zetian's visit to China.

The United States is the most developed country, while China is currently the country with the most potential and the fastest development speed.The relationship between these two countries affects the development of countries around the world.

As a Chinese, Li Zetian is of course very happy to establish a good diplomatic relationship with China.

During Li Zetian's visit to China, the faces of some people in Taiwan and Japan became very ugly.

In fact, since Li Zetian became the president of the United States, some people in Taiwan and Japan have been anxious.

How big is Taiwan, how can it challenge the huge China? Isn't it because of the backing of the United States?But now, the president of the United States is Li Zetian. In this case, can the United States still support Taiwan?

Since 2013, the situation in Taiwan has changed dramatically.

Of course, Japan is not much better. The relationship between Li Zetian and the Japanese consortium can be said to be in dire straits.After Li Zetian took office in the United States, the market value of companies under the Japanese consortium plummeted one after another.In addition, in the United States, Japanese companies have been suppressed by many places.Li Zetian euphemistically said that he protects local American companies.

Speaking of American companies, at present, Li Zetian's business tentacles have covered all walks of life. With the help of his huge financial resources, fame and various resources, sparks and lightning all the way. , The Buddha blocks and kills the Buddha.

In less than a year, Li Zetian's enterprises have formed absolute monopoly advantages in the Internet, artificial intelligence, manufacturing, telecommunications, aerospace, arms, finance, insurance, transportation, pharmaceuticals, energy, retail, food, entertainment, etc. , Li Zetian's worth has also skyrocketed crazily. There is a lot of money. Even Li Zetian himself doesn't know how much he has. Anyway, it should exceed 30 trillion U.S. dollars!

Right now, the U.S. economy is developing very fast thanks to the support of Li Zetian, but it is developing so fast that it must seek more markets and sell U.S. products to other countries.

Looking at the world, India, the most populous country, and the two continents of Africa and South America will be Li Zetian's main targets.

After visiting China, Li Zetian went to India nearby to discuss trade issues between the two countries.After meeting the Indian leaders, Li Zetian directly stated that he asked India to develop more industries for American companies to enter, such as banking, insurance, telecommunications, transportation, energy and so on.

Generally speaking, the country is willing to cooperate with the United States in order to seek development, but banking, insurance, telecommunications, transportation, energy, etc. are all important industries related to people's livelihood, which are generally dominated by the country and cannot be easily controlled by foreign companies.

The Indian leader hesitated and held a meeting to discuss it for a while.

However, in the end, Li Zetian used money to open the way, which made them relax.Of course, Li Zetian's strong attitude also played a big role-if you don't cooperate, I will suppress you. I am now the president of the United States, representing the United States, so I ask you if you are afraid? ? ?Of course, what Li Zetian said was not so straightforward and vulgar.

But no matter what, the final result still satisfied Li Zetian.

This populous country with more than one billion people represents huge potential and market.

"President Ram, don't worry, with the support of the United States, India will definitely develop very fast!" Li Zetian said with a smile on his face, but he thought in his heart, ah, India, what a place to dump products! ! !

President Ram nodded in satisfaction. Li Zetian promised that after opening up multiple industries in India, he would lend India 500 billion U.S. dollars.

"I hope that the cooperation between the United States and India will be happy!" President Rahm held out his hand.

"Hehe, I hope the cooperation between the US and India will be happy!" Li Zetian shook hands with me, then said goodbye, boarded the plane, and prepared for the next stop in the afternoon.

Speaking of aircraft, the current special plane of the President of the United States has become the latest airliner of Chronos Industries - the Space-X2012 ultra-large long-range airliner. The external price is 3.5 million US dollars, which is 380 million US dollars more expensive than the European Airbus A0.5.However, if the cost of repairs and other expenses are included, the total value of this US president's album exceeds 10 billion US dollars, and it can be regarded as the most luxurious presidential plane in the world.

Previously, the US President's special plane has always used Boeing's aircraft.

The so-called "fat water does not flow to outsiders' fields" is unlucky for Boeing.

The next stop, Li Zetian came to Saudi Arabia.

Although electric vehicles are developing well now, the price of oil is still high. Therefore, there are many local tyrants in Saudi Arabia, and they have a lot of money in their hands.

"I really envy people who can make a lot of money sitting at home!"

Li Ze got off the plane and saw the prosperous modern city-Riyadh, he couldn't help but sigh in his heart.

At this time, a group of people from the King of Saudi Arabia came face to face.

"Welcome to Riyadh, Chronos Li!!!" The old Saudi King Salman stepped out of his right hand and greeted warmly.

Li Zetian shook hands with him, exchanged a few words of greeting, then looked at the city of Riyadh, and began to praise the development of the city of Riyadh, the development of the country of Saudi Arabia, and the good governance of the King of Saudi Arabia.

On the way to the hotel, Li Zetian felt that the old Saudi king seemed to be getting a little giddy after being praised by him.

Li Zetian was speechless and shook his head, the Saudi country is developing so fast, don't you have any points in your mind?If Saudi Arabia has no oil, how different is it from its poor neighbor Yemen?

Not long after, King Salman of Saudi Arabia arranged for Li Zetian and his party to come to the Sifang Palace.

The Sifang Palace is also the royal palace of Saudi Arabia. It shows the unique artistic charm and cultural heritage of Saudi traditional architecture everywhere. It has not only modern facilities, developed transportation, and comfortable environment, but also historic palaces, exquisite furnishings, and precious treasures. cultural relics.The biggest feeling for Li Zetian is that the trenches are rushing towards his face! ! !

"Chronos Li, after we finish dinner, I will ask someone to arrange a sword dance and other Saudi folk performances, so that you can experience the Saudi folk culture." Salman said enthusiastically.

"Okay." Li Zetian nodded with a smile, but he was thinking in his heart how to get Saudi to pay for it...
