Some time ago, the world's first quantum satellite, which was developed by China, was screened, and quantum technology also entered the eyes of ordinary people. In fact, a “quantum technology fever†is being set up on a global scale. A mainstream consensus is that quantum computing and quantum computing are the most important directions in the field of quantum information technology.
At present, the development of traditional computers has gradually encountered a series of problems such as power wall and communication wall, and the performance of traditional computers has become increasingly difficult. Quantum computers have super-parallel computing capabilities that go far beyond classical computers. For example, to find a 300-bit quality factor, the best traditional computer may take thousands of years to complete, and quantum computers can in principle be completed in a short period of time. Therefore, quantum computing has outstanding advantages in nuclear explosion simulation, cryptography, materials and micro-nano manufacturing, and is a recognized development trend in the field of high-performance computing.
Focusing on the world, quantum computers are being studied in many countries including the United States, Europe, Russia and Australia. The US government and companies have the most complete layout in quantum computer development. In 2014, IBM announced a $3 billion development of next-generation chips, primarily quantum computing and neural computing. In addition, Microsoft Vice President Peter Lee also claimed that Microsoft's biggest investment in research is quantum computing.
Unlike countries such as the United States and Europe, which have long recognized and studied quantum technology, China's research on quantum computers has just begun. Although the development of the field of quantum computing in China is good, there are still many things to be done. On the one hand, the state should strengthen its layout in the development of quantum computers and raise it to the national strategic level; on the other hand, the cultivation of young talents in the field of quantum computing is also crucial.
As for when the real quantum computer will appear, Bill Gates believes that quantum computers are expected to be used in cloud computing within 10 years; the quantum declaration drafted by European scientists predicts that general-purpose quantum computers may be in 2035. Built before. The answer given by Chinese researchers is that it will be realized in 10 years and 15 years. By then, replacing traditional PCs is no longer a dream.
