Google’s new quantum computer has learned to perform calculations in seconds that take decades for even the most powerful analog supercomputers to process. In this respect informs Edition of The Telegraph, which references a preprint of a Google article posted on the ArXiv website.
Google introduced its first quantum computer in 2019. The device had 53 qubits and in 200 seconds ran an algorithm that took 10,000 years for one of the most powerful supercomputers of the time, the IBM Summit. But then the scientific world did not take Google’s explanation seriously and criticized its comparison.
Almost four years later, Google published a new article where they talk about a second-generation 70-qubit quantum computer. According to The Telegraph, the new system is 241 million times more powerful than its predecessor. The American computing giant said that its new quantum computer solved a 47-year-long problem for the world’s most powerful supercomputer Frontier in just 6.5 seconds. In The Telegraph, such a gap was called “quantum supremacy.”
Journalists also noted that the power of quantum and supercomputers is measured using an algorithm that has no practical value and is only of academic interest.
