According to Hong Kong's Wen Wei Po, many science and technology enterprises have made great efforts to develop quantum computer technology in recent years. A number of British media disclosed on the 20th that an internal research report of technology giant Google (Google) showed that its developed quantum computer successfully completed the problems that traditional computers need 10000 years to deal with in 3 minutes and 20 seconds, claiming that it is the first time in the world to achieve "quantum hegemony".
It is reported that 'quantum hegemony' means that quantum computers deal with operations that traditional computers cannot perform, or become an important milestone in quantum science. However, some people believe that the public has misunderstood the concept of "quantum hegemony" and believe that quantum computers cannot replace traditional computers. Google's research report was first disclosed by the financial times. In addition, the report was uploaded to the official website of NASA earlier this week, but was quickly deleted later. Neither Google nor NASA responded to the report.
Better than the most advanced traditional supercomputer
It is reported that the report points out that Google researchers have built a 53 qubit quantum computer with 'sycamore' as the code name. " The operation carried out by the 'Suzuki' quantum computer is to prove that a random number generator meets the 'random' standard. According to the report, even the most advanced traditional supercomputer 'summit', which samples an instance of a quantum circuit 1 million times, takes 10000 years to process, but 'sycamore' only takes 200 seconds to complete the operation.
Google researchers who wrote the report believe that although the operation processed by 'sycamore' has no practical significance, the experimental results show that the operation can only be carried out on the quantum computer to realize 'quantum hegemony'. If the research report can be recognized by the academic community later, it will become a watershed in quantum science.
Researchers also predict that the computing power of quantum computers will show a "double exponential growth rate", surpassing the "Moore's law", and the computing power of traditional computers will double in about two years.
IMB's new quantum computer will be available to customers in October
According to the report published by Boston Consulting in November 2018, if quantum computers can be mass produced, it will break the boundaries of traditional computers, increase the computing power of computers, and reform the ecology of cryptography, chemistry, artificial intelligence, and even logistics, finance, energy and other fields.
At present, in addition to Google, international business machines (IBM), Intel and other enterprises are developing quantum computers. IBM also successfully created 53 qubit computers earlier in September. It is the 14th quantum computer of IBM and the one with the highest computing power. It plans to provide 53 qubit computers to customers online from October.
Google had expected to achieve 'quantum hegemony' by the end of 2017 and once set up a 72 qubit computer, but it changed to study 53 qubits because it was too difficult to control.
Braille, founder of riverlane, a quantum software startup, believes that Google's achievements this time are a milestone. For the first time, someone has proved that quantum computers outperform traditional computers. However, Jill, director of IBM Research Institute, believes that the public has always misunderstood the concept of "quantum hegemony" because quantum and traditional computers have their own advantages. It is believed that quantum computers can not replace traditional computers, but will work together with each other&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;
