Can you explain about Quantum Supremacy?

1. In order to attain "Quantum Supremacy," Google has to develop a quantum computer that could complete operations that would normally take modern supercomputers tens of thousands of years to complete. Google will begin utilising these novel advancements for profit around 2020.

The experimental proof of a quantum computer's superiority over classical computers by executing calculations that were previously impossible at unmatched speeds is known as quantum supremacy.
