Abstract

We discuss the Wigner functions and tomographic probability distributions of two-qubit states. We give the kernel of the map, which provides the expression of the state tomogram in terms of the Wigner function of the two-qubit state, in an explicit form. Also we obtain the kernel of the inverse map and elucidate the connection of the constructed maps with the star-product scheme of quantization.
