Although the computing power of supercomputers at this time has been very fast, in order to support the huge and complex virtual world, it is necessary to need more powerful computers, and quantum computers are undoubtedly the best choice!

What is a quantum computer?

A quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, and to store and process quantum information. A code that a classical computer takes 100 years to decipher, a quantum computer can do it in 1 second.

Quantum computers are capable of reducing the running time of some complex problems that classical computers need to deal with for tens of thousands of years to a few seconds.

In fact, as early as the sixties and seventies of the 20th century, Nobel laureate in physics Richard Feynman proposed the concept of quantum computers, and after many years of research, this technology has achieved initial results.

Li Zetian has many companies that have made great achievements in the field of quantum computers, such as Intel, IBM, Microsoft, ......

Intel focuses on developing quantum chips.

Microsoft focuses on developing programming languages for quantum computers.

And IBM is committed to developing quantum computers.

At first glance, it seems to be back to the time when personal computers were 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 of Intel, who told Li Zetian that Intel had developed a 49-qubit test chip!!

Some people may think that the test chip is only 49 qubits, so what's the big deal?!

But it's just amazing, and Intel even sees it as a milestone!!

As we all know, traditional computers are binary, that is, they can only use "0" and "1" to record all the information states, and each step can only do 2 times - 2 times of operation.

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

You must know that the world's strongest supercomputing Shenwei Taihu Light is 930 million times per second, and the current world's top six-core processor i7-8700K is only about 110 billion times, how many times is a 49-qubit chip than the i7-8700K processor?

Once the 50-qubit chip is overcome, quantum computers will surpass all existing supercomputers and be able to solve problems that no computer can solve. 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 coined the term "quantum supremacy," which refers to the fact that when quantum computers reach 50 qubits, they will have more computing power than any computer in the world.

At present, 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 Intel can continue to work hard and develop tens of thousands, or even millions of qubits, in the next few years!"

Although Li Zetian's requirements were more demanding, Wei Xiuping still nodded, from a business point of view, qubits need to reach at least 1 million.

Wei Xiuping said in a deep voice: "Yes, Mr· Li, 49 qubits are far from enough, and the commercial goal of quantum computing is still a long way off, but we are confident that more qubit chips will be developed in a very short time!"

"Hmm. Li Zetian smiled and nodded. As early as two months ago, Intel launched a 17-qubit chip, but it has only been a long time since the 49-qubit chip was developed. Li Zetian couldn't help but believe that Intel would definitely be able to develop chips with more than 1,000 qubits in the next few years!!

Often, breakthroughs in some key technologies will bring about leapfrog changes, from tens or hundreds to thousands, tens of thousands, or even hundreds of thousands. For example, the processor chip developed by Intel using the 12nm process contains about 8 billion transistors, and the number of transistors on the chip suddenly soars to 20 billion when the 7nm process is successfully developed the following year.

The power of a quantum computer does not need to be repeated, and a powerful quantum chip can make a powerful quantum computer. It can be seen that quantum chips can be called the ultimate chips!!

After hanging up the phone, Li Zetian's heartbeat couldn't help but accelerate slightly 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, communications, the Internet, and big data.

……

Being the president of the United States is actually not very busy, and many things are done by other people, and Li Zetian only needs to make the final decision. George W. Bush took a total of 879 days off during his eight-year presidency, and Li Zetian decided to carry it forward to more than 1,000 days.

The reason why Li Zetian became the president is because of power, and with power, he can cover his own business. Of course, he is not going to be the president to death.

At the beginning of September, Li Zetian, Dongfang Yuqin and Yu Jingqiu appeared on the bright Hawaiian beach, enjoying life comfortably. The only difference from the previous one was that he brought a "miniature" version of the White House with about 200 people, including White House aides, secret agents, military staff, communications and transportation experts. In fact, presidents can do almost anything he can do in the White House while on vacation.

Li Zetian thinks this is very good, it is too boring to stay in the White House.

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

Immediately, the eyes of the world were 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 growing rate. 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 good diplomatic relations 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 president of the United States, some people in Taiwan and Japan have been nervous.

No matter how big Taiwan is, how can it compete with the huge China, isn't it just that it has the support of the United States behind it? But now, the US president is Li Zetian, so can the United States still support Taiwan?

Since 2013, the situation in Taiwan has changed dramatically.

Of course, Japan is not much better, and Li Zetian's relationship with the Japanese consortium can be said to be in dire straits. After Li Zetian became the United States, the market value of the companies under the Japanese consortium plummeted. In addition, in the United States, Japanese companies have been suppressed in many places. Li Zetian said in the name of protecting local American enterprises.

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, crazy and cool hanging to blow up the sky, God blocks and kills God, and Buddha blocks and kills Buddha.

In less than a year, Li Zetian's enterprises have formed an absolute monopoly advantage in many fields such as the Internet, artificial intelligence, manufacturing, telecommunications, aerospace, arms, finance, insurance, transportation, pharmaceuticals, energy, retail, food, entertainment, etc., and Li Zetian's worth has skyrocketed wildly, and even Li Zetian himself doesn't know how much money he has, anyway, it should exceed 30 trillion US dollars!

At present, the US economy is developing very rapidly because of Li Zetian's support, but it is developing rapidly, and it is necessary to seek more markets and sell US products to other countries.

Globally, India, the most populous country, and two continents, Africa and South America, will be Li's main targets.

After his visit to China, Li Zetian went to India to discuss trade issues between the two countries. After meeting with the Indian leader, Li Zetian bluntly said 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 of course 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 led by the state and cannot be easily controlled by foreign companies.

The Indian leader hesitated and held a meeting for a while.

However, in the end, Li Zetian used money to open the way, which made them relieved. Of course, Li Zetian's strong attitude also played a great role - if you don't cooperate, Lao Tzu will suppress you, Lao Tzu is now the president of the United States, representing the United States, just ask if you are afraid??? of course, what Li Zetian said is not so straightforward and rude.

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

This large country with a population of more than one billion people represents a huge potential and market.

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

President Ram nodded with satisfaction, and Li Zetian promised that after India opens up a number of industries, it will borrow $50 billion to India, and at the same time, hundreds of billions of dollars of overseas investment will quickly enter the Indian market.

"I hope the United States and India have a happy cooperation!" said President Ram held out his hand.

"Hehe, I hope the United States and India have a happy cooperation!" Li Zetian shook hands with me, then said goodbye, got on the plane, and prepared for the next stop in the afternoon.

Speaking of airplanes, the US president's current plane has become the latest passenger aircraft of Chronos Industries, the Space-X2012 ultra-large long-range airliner, which costs $350 million to the outside world, which is $50 million more expensive than the European Airbus A380. But if you add in the cost of repairs and other expenses, the total value of this album of the American president exceeds $1 billion, which can be called the most luxurious presidential plane in the world.

Previously, the special plane of the President of the United States had always used aircraft made by Boeing.

The so-called "fertilizer and water do not flow into the fields of outsiders" is unlucky for the Boeing company.

At his next stop, Li Zetian came to Saudi Arabia.

Although electric vehicles are developing well, the price of oil is still high, so there are many local tycoons in Saudi Arabia and 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 couldn't help but sigh in his heart when he saw the prosperous modern city of Riyadh.

At this time, a group of people from the Saudi king approached.

"Welcome to Riyadh, Chronos· Li !! "The old Saudi king Salman walked out of his right hand and greeted him warmly.

Li Zetian shook hands with him, exchanged a few pleasantries, and then looked at the city of Riyadh and began to praise the good development of the city of Riyadh, the good development of the Saudi state, and the good governance of the Saudi king.

On the way to the hotel, Li Zetian felt that the old Saudi king seemed to be a little fluttering by his own praise.

Li Zetian was speechless and shook his head, Saudi Arabia is developing so fast, don't you have a point in your heart? If Saudi Arabia has no oil, how different is it from the poor neighboring country Yemen?

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

Sifang Palace is also the royal palace of Saudi Arabia, which shows the unique artistic charm and cultural heritage of traditional Saudi architecture, with modern facilities, developed transportation, comfortable environment, and historic palaces, exquisite furnishings, and precious cultural relics. The biggest feeling for Li Zetian is the trench that rushes to his face!!

“Chronos· Li, when we finish dinner, I will ask people to arrange Saudi folk performances such as sword dances, so that you can feel the customs and culture of Saudi Arabia. Salman said enthusiastically.

"Okay. Li Zetian smiled and nodded, but he was thinking in his heart, how to get Saudi Arabia to pay for it......
