ABSTRACT:
An apparatus (1) and method for decoupling error correction from privacy amplification in a quantum key distribution (QKD100) system includes two or more computer systems (102, 108) linked by quantum and classical channels (120, 122) where each computer system determines a generalized error syndrome associated with quantum communication between the systems, encrypts the generalized error syndrome using a sequence of values, and communicates the encrypted generalized error syndrome via a classical channel (128) to the other system, which uses the encrypted generalized error syndromes to compute error correction for the quantum transmission.
