qml.decomposition.has_decomp¶
- has_decomp(op_type)[source]¶
Checks whether an operator has decomposition rules defined.
Note
This function is only relevant when the new experimental graph-based decomposition system (introduced in v0.41) is enabled via
enable_graph(). This new way of doing decompositions is generally more resource efficient and accommodates multiple alternative decomposition rules for an operator.- Parameters
op_type – the operator class to check for decomposition rules.
- Returns
whether decomposition rules are defined for the given operator.
- Return type
