This is the best kind of correct but it's an interesting phrasing since Fredkin is a kind of Quantum supremacy skeptic (hotkey-find Classicatopia in: https://windowsontheory.org/2017/10/30/the-different-forms-o...).

Fredkin's contribution were to reversible computation and since Quantum computers are a kind of reversible computer, many ideas and gate notions carried over.
