Query: Wigner functions and spin tomograms for qubit states   We establish the relation of the spin tomogram to the Wigner function on a
discrete phase space of qubits. We use the quantizers and dequantizers of the
spin tomographic star-product scheme for qubits to derive the expression for
the kernel connecting Wigner symbols on the discrete phase space with the
tomographic symbols.
