Spin tomography and star-product kernel for qubits and qutrits
arXiv:0904.1124 · doi:10.1007/s10946-009-9065-2
Abstract
Using the irreducible tensor-operator technique, we establish the relation between different forms of spin tomograms. Quantizer and dequantizer operators are presented in simple explicit forms and are specified for the low-spin states. The kernel of the star-product is evaluated for qubits and qutrits and its connection with a generic formula is found.
