We present an analytical method for determining the quarter-half-quarter (QHQ) wave-plate settings required to implement a prescribed $\mathrm{U}(2)$ polarization transformation, up to a physically irrelevant global phase. The method addresses the inverse problem in which the desired operation is specified as a unitary matrix rather than by Euler angles or optical-element orientations. By...
