Function Documentation

transpile_to_ibm_eagle()

def wide_circuit_optimization.transpile_to_ibm_eagle	(		qasm_path_or_circ,
			parameters = None
	)

Transpile a circuit to IBM Eagle's native gate set and return consistent
gate stats via Squander's CircuitGateStats.

Args:
    qasm_path_or_circ: Either a path to a .qasm file, or a Squander Circuit.
    parameters: Required if passing a Squander Circuit.

Returns:
    dict from CircuitGateStats, using the same decomposition as the main
    benchmark pipeline.
