The Impact on Chemistry
The term "quantum supremacy" was coined in 2012 by Caltech's John Preskill. Scientists foresaw a state where a quantum computer would be able to do a task that a classical computer could not. That is a very loose definition of quantum supremacy though. That is perhaps what allowed Google to claim that they have achieved quantum supremacy with their Sycamore chip.
The Sycamore is a 54-qubit processor that is able to generate random numbers. The algorithm used to do that would take over 10,000 years to do the same task using a classical computer, whereas it took 200 seconds on the Sycamore. IBM had its objections to this claim. They calculated that the entire quantum state vector of Google's Sycamore chip could be stored within Summit – the world's largest supercomputer, with 250 petabytes of storage.
Scientists who reviewed the work done by Google have revealed that the processor had high-fidelity and superfast...
