The computer industry has always been the focus of the whole society. The recent emergence of new technologies such as quantum computers and supercomputers has once again increased the popularity of the computer industry. Just recently, Google launched the new Sycamore (planetary tree) quantum computer, which can complete the 10,000-year complex computing task required by the world's strongest supercomputer in just 200 seconds, which shocked the scientific community. Google officially claimed that this technological breakthrough is comparable to the glorious moment when the Wright brothers invented the world's first airplane in 1903, symbolizing the arrival of the quantum era in the history of human science and technology!

The concept of quantum computer was first proposed by Richard Feynman, the American Nobel Laureate in Physics in the early 1980s , The reversible computing computer model designed using the principles of quantum mechanics can achieve exponential levels faster than traditional computers. Google, as a pioneer in quantum computers in the world, has researched the quantum field for more than ten years, and the latest development of superconductor quantum processing Sycamore, with 53 qubits, can store a total of 253 qubits, which is equivalent to 9.7 petaflops of storage.

In order to verify the capabilities of the Wutong tree quantum computer, Google also designed A series of comparison tests were conducted to compare the plane tree with the US Department of Energy’s supercomputer Summit. Finally, Google's Sycamore quantum computer can complete the probability of occurrence of 253 random random numbers in only 200 seconds, but the Summit supercomputer of the US Department of Energy takes 10,000 years.

However, Google’s veteran competitor, IBM, opposed this statement, and they also published an article to refute the authenticity of Google’s quantum computer. IBM stated that Google’s hypothetical algorithm did notAfter the IBM team re-modified the algorithm for the computing advantages of high-level computers, it is estimated that the computing time of supercomputers will be significantly reduced from 10,000 years to 2.5 days.

IBM's result is that quantum computers have advantages, but there is not a gap of 200 seconds and 10,000 years. Supercomputers in the United States take 2.5 days to complete. Moreover, IBM believes that quantum computers and supercomputers have their own strengths, and that the two should be in a cooperative relationship. The development of quantum computers is not to replace traditional computers. The irony of Google is too exaggerated and exaggerated.

Currently, Google is not the only one who is studying quantum computers, like IBM and some computers are also working on quantum computers Explore, but Google’s results are faster. IBM also started the research and development of quantum computers a few years ago, but it is still a bit worse than Google.
