Giant of the times - Chapter 547

c538 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 inevitably needed, and quantum computers are undoubtedly the best choice!

What is a quantum computer?

Quantum computer is a type of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. A code that would take a classical computer 100 years to decipher can be solved by a quantum computer in just one second.

Quantum computers can reduce the running time of some complex problems that require tens of thousands of years for classical computers to be processed to a few seconds. You can imagine how awesome quantum computers are!

In fact, as early as the 1960s and 1970s, 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 focuses on developing quantum chips.

Microsoft is focused 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 starting out.

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

Just yesterday, Li Zetian received a call from Wei Xiuping of Intel. He told Li Zetian that Intel had developed a 49-qubit test chip! ! !

Some people may think that there is something so special about a test chip with only 49 qubits? !

But it is so amazing that Intel even considers it a milestone! ! !

As we all know, traditional computers are binary, that is, they can only use “0” and “1” to record all information states. Each step can only do 2 to 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 perform 2 to the power of 2 in each step – that is, 4 operations. Therefore, Intel’s chip can reach 2 to the power of 49 in one step, which is 562 trillion times.

You must know that the current world’s most powerful supercomputer Sunway TaihuLight is 930 billion times per second, and the current world’s top six-core processor i7-8700K is only about 110 billion times. A 49-qubit chip is i7 -How many times the 8700K processor?

Once the 50-qubit chip is conquered, quantum computers will surpass all existing supercomputers and be able to solve any problem that cannot be solved by computers. A quantum computer with 300 qubits could support more parallel computations than there are atoms in the universe! ! !

In 2012, Caltech quantum theorist John Preskill proposed a term – “quantum supremacy”, which refers to the fact that when a quantum computer develops to 50 qubits, its computing power will exceed that of 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 is not enough. I hope Intel can continue its efforts and develop computers with tens of thousands or even millions of qubits in the next few years!”

Although Li Zetian’s requirements were relatively harsh, Wei Xiuping still nodded. From a commercial perspective, the number of qubits needs to reach at least 1 million.

Wei Xiuping said solemnly: “Yes, Mr. Li, 49 qubits are far from enough. The commercial goal of quantum computing still has a long way to go, but we are confident that we can develop more qubits in a very short time.” chip!”

“Yeah.” Li Zetian smiled and nodded. As early as two months ago, Intel launched a 17-qubit chip. However, just a short time ago, a 49-qubit chip was developed. Li Zetian couldn’t help but believe that Intel will definitely be able to develop a chip with more than 1,000 qubits in the next few years! ! !

Breakthroughs in some key technologies often bring about leap-forward changes. It is possible to jump from dozens or hundreds to thousands, tens of thousands, or even hundreds of thousands. This is how the number of transistors on traditional chips changes. For example, the processor chip developed by Intel using the 12-nanometer process contains about 8 billion transistors. The 7-nanometer process was successfully developed the following year, and the number of chip transistors suddenly jumped to 20 billion.

It goes without saying that the power of quantum computers is powerful, but only powerful quantum chips can create powerful quantum computers. It can be seen that the quantum chip is simply the ultimate chip! ! !

After hanging up the phone, Li Zetian’s heartbeat accelerated slightly when he thought about 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. Many other people have to do many things. Li Zetian only needs to make the final decision. George W. Bush took a total of 879 days of vacation during his eight-year term as president, and Li Zetian decided to carry it forward to more than 1,000 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 become the president.

In early September, Li Zetian, Dongfang Yuqin and Yu Jingqiu appeared on the beautiful Hawaiian beach, enjoying life comfortably. The only difference from before is that he brought a “miniature version” of the White House with him, about 200 people, including White House assistants, special agents, military staff, communications and transportation experts. In fact, presidents can do almost anything they can do in the White House while on vacation.

Li Zetian thinks this is good. Staying in the White House is really boring.

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

Immediately, the world’s attention focused on Li Zetian’s visit to China.

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

As a Chinese, Li Zetian is of course very willing 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 become anxious.

How can Taiwan, a country as big as Taiwan, challenge China, because it has 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 undergone rapid changes.

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 came to the United States, the market value of the companies owned by the Japanese consortium dropped sharply. In addition, in the United States, Japanese companies have been suppressed by many places. Li Zetian’s euphemistic name is to protect local American companies.

Speaking of American companies, Li Zetian’s business tentacles have now covered all walks of life. With the help of his huge financial resources, fame and various resources, he has sparkled with lightning all the way, making him cool and shocking, and killing gods. , Buddha blocks and kills Buddha.

In less than a year, Li Zetian’s company has formed absolute monopoly advantages in the Internet, artificial intelligence, manufacturing, telecommunications, aerospace, arms, finance, insurance, transportation, pharmaceuticals, energy, retail, food, entertainment and other fields. , Li Zetian’s net worth has also skyrocketed crazily. He has so much money that even Li Zetian himself doesn’t know how much it is. Anyway, it should exceed 30 trillion US dollars!

At present, the U.S. economy is developing very fast due to the support of Li Zetian, but with rapid development, it must seek more markets and sell U.S. products to other countries.

Looking around the world, India, a 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 to discuss trade issues between the two countries. After Li Zetian met with Indian leaders, he bluntly stated that he required India to develop more industries for American companies to enter, such as banking, insurance, telecommunications, transportation, energy, etc.

Generally speaking, countries are willing to cooperate with the United States in order to seek development. However, banking, insurance, telecommunications, transportation, energy, etc. are all important industries related to people’s livelihood. They are generally led by the state and cannot be easily controlled by foreign companies.

Indian leaders hesitated and held meetings to discuss for a long time.

However, in the end, Li Zetian used money to clear the way for them to 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 and represent 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 quickly!” Li Zetian said with a smile on his face, but thinking in his heart, ah, India, what a good product dumping place! ! !

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

“I hope the United States and India can have happy cooperation!” President Ram extended his hand.

“Haha, I hope the cooperation between the United States and India will be happy!” Li Zetian shook hands with me, then said goodbye and got on the plane to prepare for the next stop in the afternoon.

Speaking of airplanes, the current special plane of the US President has become the latest passenger aircraft of Chronos Industries – the Space-X2012 ultra-large long-range passenger aircraft, which is priced at US$350 million, which is US$50 million more expensive than the European Airbus A380. But if the cost of repairs and other expenses are included, the total value of this US president’s album exceeds 1 billion U.S. dollars, making it the most luxurious presidential plane in the world.

Previously, the U.S. president’s special plane had always used aircraft produced by Boeing.

The so-called “rich water does not flow to outsiders”, which is bad luck for Boeing.

Next stop, Li Zetian came to Saudi Arabia.

Although electric vehicles are developing well now, oil prices are still high. Therefore, there are many rich people in Saudi Arabia who have a lot of money in their hands.

“I really envy people who can make a lot of money while sitting at home!”

When Li Zetian got off the plane and saw the prosperous modern city of Riyadh, he couldn’t help but sigh in his heart.

At this time, King Saud and a group of people came towards him.

“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 pleasantries, then looked at the city of Riyadh, and began to praise the city of Riyadh for its good development, the country of Saudi Arabia for its good development, and the King of Saudi Arabia for his good governance.

On the way to the hotel, Li Zetian felt that the old Saudi king seemed to be so flattered by his praise.

Li Zetian was speechless and shook his head. Saudi Arabia is developing so fast, don’t you have any ideas in mind? If Saudi Arabia had no oil, how different would it be from its poor neighbor Yemen?

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

The Sifang Palace is the royal palace of Saudi Arabia. It displays the unique artistic charm and cultural heritage of traditional Saudi architecture. It has modern facilities, developed transportation, and a comfortable environment, as well as historical palaces, exquisite furnishings, and precious treasures. cultural relics. The biggest feeling for Li Zetian was the rush of trench in front of him! ! !

“Chronos Li, after we finish dinner, I will arrange for sword dancing and other Saudi folk performances to let you experience the Saudi folk culture.” Salman said enthusiastically.

“Okay.” Li Zetian smiled and nodded, but he was thinking about how to get Saudi Arabia to pay…
