Zusammenfassung: | The invention discloses a basis-vector-mixed quantum secret key distribution post-processing method and belongs to the field of quantum key processing. The method comprises the following steps: step 1, a sender carries out basis vector mixing on a produced quantum key and then sends the quantum key to a receiver; 2, the sender and the receiver randomly select basis vectors in different directions respectively to prepare and measure a quantum state, and N-bit key information and N-bit basis vector information are stored in the sender and the receiver after multiple rounds of quantum signal transmission; and 3, the two parties carry out comparation on basis vectors, the keys with different basis vectors when the quantum signals are sent and received are discarded, the quantity of the basis vectors in different directions is calculated according to the basis vector information of the remaining keys, and the basis vector information is discarded. In order to solve the problem that the quantum secret key mixed bas |
