# qiskit.converters.circuit_to_gate¶

circuit_to_gate(circuit, parameter_map=None, equivalence_library=None, label=None)[Quellcode]

Build a Gate object from a QuantumCircuit.

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

Parameter
• 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 gate. If None, existing circuit parameters will also parameterize the Gate.

• equivalence_library (EquivalenceLibrary) – Optional equivalence library where the converted gate will be registered.

• label (str) – Optional gate label.

Verursacht

QiskitError – if circuit is non-unitary or if parameter_map is not compatible with circuit

Rückgabe

a Gate equivalent to the action of the input circuit. Upon decomposition, this gate will yield the components comprising the original circuit.
