qat.frontend.fallthrough module

class FallthroughFrontend(model=None)

Bases: BaseFrontend

A frontend that passes through an input InstructionBuilder and does not modify it. Used in situations where a frontend is not required, but is used to make a pipeline complete.

Parameters:: model¶ (Union[None, QuantumHardwareModel, PhysicalHardwareModel]) – The hardware model that holds calibrated information on the qubits on the QPU.

check_and_return_source(src): All source files are valid for the FallthroughFrontend.

emit(src, res_mgr=None, met_mgr=None, compiler_config=None)

Compiles an input QatInput down to QatIR and emits it. :type _sphinx_paramlinks_qat.frontend.fallthrough.FallthroughFrontend.emit.src: InstructionBuilder :param _sphinx_paramlinks_qat.frontend.fallthrough.FallthroughFrontend.emit.src: The high-level input. :type _sphinx_paramlinks_qat.frontend.fallthrough.FallthroughFrontend.emit.res_mgr: Optional[ResultManager] :param _sphinx_paramlinks_qat.frontend.fallthrough.FallthroughFrontend.emit.res_mgr: Collection of analysis results with caching and aggregation

capabilities, defaults to None.

Parameters:

met_mgr¶ (Optional[MetricsManager]) – Stores useful intermediary metrics that are generated during compilation, defaults to None.
compiler_config¶ (Optional[CompilerConfig]) – Compiler settings, defaults to None.

Return type:

InstructionBuilder

Returns:

An intermediate representation as an InstructionBuilder which holds a list of instructions to be executed on the QPU.
