Google's quantum computer is 241 million times more powerful than it was 2019

Google has reportedly built a quantum computer that performs calculations in moments that would take the world's most advanced supercomputers nearly half a century. Its Sycamore processor now has 70 qubits, up from 53 in the earlier version, and according to the Google team, the Frontier supercomputer in Tennessee would need 6.18 seconds to match a 53-qubit calculation but 47.2 years to match a 70-qubit one. The team published its findings in an arXiv pre-print paper. Steve Brierley, chief executive of Riverlane, called the advance a "major milestone," while critics argue these machines still need more practical use beyond academic research.
