by Both are parametrized gates but most importantly, they are derived from the all-encompassing U₃-gate. In fact, every gate introduced in this article can be represented using the U₃-gate. It is, as expected, a parametrized gate whose matrix is given by One can observe that U₁ = U₃(0,0,λ) and U₂ =
