qiskit.converters.circuit_to_instruction¶

circuit_to_instruction(circuit, parameter_map=None, equivalence_library=None)[ソース]¶

Build an Instruction object from a QuantumCircuit.

The instruction is anonymous (not tied to a named quantum register), and so can be inserted into another circuit. The instruction will have the same string name as the circuit.

パラメータ

circuit (QuantumCircuit) – the input circuit.
parameter_map (dict) – For parameterized circuits, a mapping from parameters in the circuit to parameters to be used in the instruction. If None, existing circuit parameters will also parameterize the instruction.
equivalence_library (EquivalenceLibrary) – Optional equivalence library where the converted instruction will be registered.

例外

QiskitError – if parameter_map is not compatible with circuit

戻り値

an instruction equivalent to the action of the input circuit. Upon decomposition, this instruction will yield the components comprising the original circuit.

戻り値の型

qiskit.circuit.Instruction
