A quantum computing system and a method of performing a quantum error correction code are disclosed. Syndrome data is received representative of an error state of a plurality of quantum devices. Occurrence of a runtime trigger event is determined. A hypergraph modification rule associated with the runtime trigger event is retrieved from a decoding hypergraph modification map data structure comprising a plurality of predefined hypergraph modification rules. A decoding hypergraph is modified in accordance with the hypergraph modification rule to generate a modified decoding hypergraph. A correction for the error state is determined by decoding the syndrome data with the modified decoding hypergraph.
