spheres.coordinates.spinor_c

spheres.coordinates.spinor_c(spinor)

Converts spinor \(\begin{pmatrix} a \\ b \end{pmatrix}\) to extended complex coordinate.

If \(a = 0\), returns \(\infty\).

Otherwise returns \(\frac{b}{a}\).

Parameters

spinor (list or qt.Qobj) – Normalized spinor(s).

Returns

c – Extended complex coordinate(s).

Return type

complex/inf or np.ndarray
