qat.frontend.passes.transform module

class InputOptimisation(hardware, *args, **kwargs)

Bases: TransformPass

Run third party optimisation passes on the incoming QASM.

Instantiate the pass with a hardware model.

Parameters:

model – The hardware model is used in TKET optimisations.

run(program, res_mgr, met_mgr, *args, compiler_config, **kwargs)
Parameters:

  • program (str) – The program as a string (e.g. QASM or QIR), or filepath to the program.

  • res_mgr (ResultManager) – The results manager to look-up the InputAnalysisResults.

  • met_mgr (MetricsManager) – The metrics manager to save the optimised circuit.

  • compiler_config (CompilerConfig) – The compiler config should be provided by a keyword argument.

before using.

class Parse(hardware)

Bases: TransformPass

Parses the QASM/QIR input into IR.

Instantiate the pass with a hardware model.

Parameters:

model – The hardware model is required to create Qat IR.
