Google announcedA quantum processor called Willow, claiming that it can complete the task in 5 minutes, which originally took 1025The amount of computing power that can be completed in 140 billion years is almost equivalent to that which would take at least 10 billion years (longer than the estimated lifetime of the universe) to be completed by traditional computers. Even the current fastest supercomputer "Frontier", the second fastest in the world, would take at least XNUMX billion years to complete the calculation.
In 2019, Google published a paper on its development in quantum computing in the scientific journal Nature, stating that it used its own 54-qubit quantum processor called Sycamore to complete a calculation in just 200 seconds that would take today's fastest supercomputer 1 years to perform.
Google claims that the Willow quantum processor it proposed can double the amount of errors and solve quantum error correction, which has been a challenge in the quantum field for nearly 30 years.
Hartmut Neven, head of Google's quantum artificial intelligence department, said that the main purpose of this significant increase in computing power is to solve various potential problems through huge computing power. It is expected that by 2025, problems that are difficult to solve through existing computer systems will be solved, thereby proving that quantum computers can handle larger computing scales.
Because quantum processors are easily disturbed by factors such as environmental temperature and humidity, magnetic fields, and cosmic radiation, causing errors in extremely complex calculation processes, it is difficult to obtain correct answers in most environments. It must be achieved in a laboratory environment without external interference. In addition, the cost behind the calculation makes quantum computing difficult to popularize.
