In 2019, Google claimed that its Sycamore quantum computer could perform calculations that would take the world’s most powerful classical supercomputers 10,000 years to complete, but it now appears that non-quantum computers can crunch numbers several times faster than Google’s machine, and use less energy to do so.
Quantum computers have the potential to perform certain calculations much faster than classical computers, but they are still in their early stages. In 2019, Google announced that Sycamore had achieved “quantum supremacy,” which means that a quantum computer can…
