Abstract: The study of highly symmetric and efficient scheme for the determination of a single-quibit state, such as the polarization properties of the photons emitted by a single-photons source was presented. The study showed that the scheme was efficient in the sense that it enables one to estimate the qubit state reliably without first detecting an enormous number of qubits. The efficiency of the new scheme could be increased by adaptive procedures in which the apparatus is adjusted in accordance with the current estimate for the qubit state. It was observed that the proposed scheme has four-output setup that provides optimal complete tomography with the minimal number of output channels.
