Abstract

A method for information reconciliation in quantum key distribution is introduced herein. In general, a first binary sequence belonging to a sender is being divided and fitted into a first blocks system having a specific number of blocks (103). At the same time, a second binary sequence belonging to a recipient is being divided and fitted into a second blocks system having the same specific number of blocks as the first blocks system (103). The first blocks system and the second blocks system correspond to each other. Parity bit comparison is then carried out between the blocks within the first blocks system and their corresponding blocks within the second blocks system to detect an error that is defined as parity bit discrepancy (107). Once detected, a matrix system within the error block of each first and second blocks systems is extracted, and parity bits of each row and each column of the matrix system within the error block of the first blocks system are compared to the parity bit of its corresponding row and column of the matrix system within the error block of the second blocks system to identify and correct the entry contributing the error (108).
