"We deal with the estimation of the state of a d-level system, d }= 2, the so-called qudit, using a somewhat formal generalization of the measurement of the Pauli operators. The optical qubits, qutrits and qudits, in general, are superpositions of quantum states with (definite) small numbers of photons or 'few-photon states'." . . "T140" . . . "15310" .
