Quantum Advantage
A milestone where quantum computers outperform classical computers on a specific task, though definitions vary on whether the task must be practically useful.
Quantum advantage refers to the point at which a quantum computer can solve a problem faster, cheaper, or more efficiently than any classical computer. The definition is contested: the original 2012 formulation by John Preskill required only computational superiority on any task, while more recent interpretations demand that the task have practical applications. This definitional ambiguity allows companies to claim quantum advantage on carefully chosen benchmarks while practical quantum utility remains years away.
