"WebApr 16, 2024 · 4. There are several basic gate sets allowing to construct any gate on a quantum gate-based computer, e.g.: H, T, C N O T (sometimes enriched to H, T, S, X, C N O T ), rotations R x, R y and R z and C N O T, Toffoli gate + H, Fredkin gate + H. I am wondering whether there are any other universal sets usually used in quantum computation. " - Build the swap gate from three cx note
