摘要

Mixed-state purification is used as a basis to formulate a general statistical method for reconstructing the density matrix of an arbitrary quantum state. A universal statistical distribution is obtained for the fidelity of the reconstructed quantum state. The proposed theory is supported by results of numerical simulations.
