 Pan Jianwei: quantum computing is a nuclear weapon in the era of peace. The United States can not afford to lose.


Pan Jianwei said that the scientific revolution usually brought about the industrial revolution. There were two scientific revolutions in human history. The first scientific revolution was brought by Newtonian mechanics. With the application of Newton mechanics, the first industrial change took place, which was represented by the steam engine. In the process, Britain emerged as the worlds top power by the end of the eighteenth Century; at the same time, as electricity technology brought second industrial changes in electrical technology, Germany was the number one power in nineteenth Century and the United States in twentieth Century. The second scientific revolution brought about by relativity and quantum mechanics was born at the beginning of the last century. It immediately gave birth to the third industrial changes, represented by information technology. In this process, Japan seized the opportunity to be promoted to an industrial power. He believes that the development of modern information technology is based on quantum technology. In the process of the development of nuclear weapons, modern universal computers have been developed, and the Internet has been created for the quantum research of high energy physics industry. However, information technology, which has been developed for so many years, has encountered some serious challenges, first of all, information security. Bottlenecks. With the development of computing power, security problems are becoming more and more serious, and all the classic encryption algorithms that rely on computational complexity will be cracked in principle, so in 1841, Pan Jianwei said, it was proposed in 1841 that human intelligence could not construct a secret code that could not be cracked by human beings. The second bottleneck, in Pan Jianweis view, is a more powerful computing power; he says the worlds computing power cant complete the exhaustive search for 2 of the 80 data in one year, and the development model of traditional computing power has been seriously constrained. Pan Jianwei said that quantum mechanics was ready to solve the two problems. Quantum is a very small particle, the most basic unit of material, and the most fundamental carrier of energy. It has an inseparable nature. In addition, there is another very interesting feature called superposition. The basic unit of our daily information processing is 0 or 1. If the cat is the representative of the cat, life and death represent 0 and 1. In the quantum world, the cat can not only be in the state of 0 or 1, but can even be superimposed on two states of birth and death. Inside, it can exist at the same time. The quantum superposition has a very strange feature, Pan Jianwei continued. Measurement will find that the state changes. Measuring it will have an impact on it. There is a quantum non cloning theorem. Quantum cannot be copied precisely because it can not be replicated by measuring it. This constitutes a quantum encryption technology. A prerequisite for security. In terms of computing power, according to Pan Jianwei, according to Pan Jianwei, the ability of quantum computing is to exponentially increase with the number of bits. The size of the trillions of classic computers will take 150000 years to decompose 300 bits, using only one second of the trillions of quantum computers; solving a multi billion variable equation group, using billions of classical supercomputing and the need of 100. In 2000, it took only 0.01 seconds to use trillions of quantum computers. So he figurative of the weight calculation as a nuclear weapon in the peace era, not only China, Britain, Europe, and the United States. Although China has some advantages in the direction of quantum technology, the United States is unable to bear the cost of losing it in the revolution of quantum technology. They are also preparing to start. Similar to China and the European Union, the quantum technology national special program to carry out quantum cryptography and electronic computing and other related technologies. Pan Jianwei believes that, with the development of quantum computing, universal quantum computing can take ten years or twenty years, but if optimizing the network and accelerating learning may become the corresponding reality in the near future, Pan Jianwei hopes to reach hundreds of quantum bits in the hope of 10-15 years.
