Only four days have passed since Google Scientists made their historic announcement for achieving “quantum supremacy”, a landmark event in computer science. However, in a well timed preemptive strike, chief competitor IBM objected stating: ”…the world’s most powerful supercomputer can nearly keep pace with Google’s new quantum machine”, Sycamore.
“Quantum supremacy”, according to theoretical physicist John Preskill, is ”the moment when a quantum computer finally surpasses even the best supercomputer”. Other experts ”interpret quantum supremacy to mean the moment a quantum computer performs a calculation that, for all practical purposes, a classical computer can’t match”. The sticking point here is the word ‘practical’; objecting scientists prefer a more meticulous metric. Most agree there is ‘something’ here, but differ on what it should be called. How very ‘quantum’; from the Latin quantus = ‘how much'…Semantics.
