UnitaryGate

class UnitaryGate(data, label=None)

ベースクラス: Gate

Class quantum gates specified by a unitary matrix.

サンプル

We can create a unitary gate from a unitary matrix then add it to a quantum circuit. The matrix can also be directly applied to the quantum circuit, see QuantumCircuit.unitary().

from qiskit import QuantumCircuit
from qiskit.extensions import UnitaryGate

matrix = [[0, 0, 0, 1],
          [0, 0, 1, 0],
          [1, 0, 0, 0],
          [0, 1, 0, 0]]
gate = UnitaryGate(matrix)

circuit = QuantumCircuit(2)
circuit.append(gate, [0, 1])

Create a gate from a numeric unitary matrix.

パラメータ

• data (matrix or Operator) – unitary operator.

• label (str) – unitary name for backend [Default: None].

例外

ExtensionError – if input data is not an N-qubit unitary operator.
