Various methods are provided for quantum computing (QC) based code-optimization. One example method may comprise identifying one or more runtime hotspots in executed code based on one or more QC algorithms and application performance monitoring, evaluating performance of the one or more runtime hotspots, selecting one QC algorithm for each identified runtime hotspot of the one or more identified runtime hotspots, and for each identified runtime hotspot, testing the selected QC algorithm to optimize the identified runtime hotspot.
