qiskit.converters.circuit_to_instruction¶

circuit_to_instruction(circuit, parameter_map=None, equivalence_library=None, label=None)[fuente]¶

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.

Parámetros

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.
label (str) – Optional instruction label.

Muestra

QiskitError – if parameter_map is not compatible with circuit

Devuelve

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

Tipo del valor devuelto

qiskit.circuit.Instruction

Ejemplo

from qiskit import QuantumRegister, ClassicalRegister, QuantumCircuit
from qiskit.converters import circuit_to_instruction

q = QuantumRegister(3, 'q')
c = ClassicalRegister(3, 'c')
circ = QuantumCircuit(q, c)
circ.h(q[0])
circ.cx(q[0], q[1])
circ.measure(q[0], c[0])
circ.rz(0.5, q[1]).c_if(c, 2)
circuit_to_instruction(circ)
