Package com.quantum4j.transpile.passes

Class U3DecompositionPass

java.lang.Object

com.quantum4j.transpile.passes.U3DecompositionPass

All Implemented Interfaces:

TranspilerPass

public final class U3DecompositionPass
extends Object
implements TranspilerPass

Decomposes U1/U2/U3 gates into native rotations:

   U3(θ, φ, λ) => RZ(φ) ; RX(π/2) ; RZ(θ) ; RX(-π/2) ; RZ(λ)
   U2(φ, λ)    => U3(π/2, φ, λ)
   U1(λ)       => RZ(λ)
