Abstract

See full text

A method for sending first data as quantum information in qubits and classical second data over a quantum channel, in particular in quantum information communication systems, includes applying quantum error correction (QECC) encoding to the qubits obtaining quantum information codewords, applying intentional errors with error syndromes representing the second classical data to the quantum information codewords obtaining quantum information codewords with intentional errors applied upon, transmitting from a transmitting side the quantum information codewords with intentional errors applied upon over the quantum channel which outputs received codewords at a receiving side, computing error syndromes from the received codewords, performing a QECC error correction operation on the received codewords by applying a correction operator obtained at least by the computed syndromes to obtain corrected codewords, and outputting the corrected codewords and the computed syndromes.
