Field: Basic communication processes (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 14:
15. A non-transitory computer readable medium comprising instructions that, when executed in a processor comprising a quantum annealer, direct the processor to correct errors in LDPC encoded data, the instructions further directing the processor to:
receive a block of Low Density Parity Check (LDPC) encoded data;
reduce a belief propagation algorithm into a quadratic polynomial, the belief propagation algorithm being used to decode the LDPC encoded data into;
mapping the quadratic polynomial onto a plurality of quantum bits (qubits) to embed the quadratic polynomial onto the qubits; and
decode the block of LDPC encoded data via the qubits with the quadratic polynomial to output a block of LDPC decoded data.
