Applying Multi-qubit Correction to Frustrated Cluster Loops on an Adiabatic Quantum Computer. (arXiv:1902.05827v1 [cs.ET])

The class of problems represented by frustrated cluster loops, FCL, is a
robust set of problems that spans a wide range of computational difficulty and
that are easy to determine what their solutions are. Here, we use frustrated
cluster loops to test the relative performance of the D-Wave without
post-processing and the D-Wave with multi-qubit correction (MQC)
post-processing. MQC post-processing has shown itself exceptionally beneficial
in improving the performance of the D-Wave 2000Q when processing difficult FCL
problems.
