UnitaryGate¶

class UnitaryGate(data, label=None)[ソース]

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].

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

Methods

 `add_decomposition` Add a decomposition of the instruction to the SessionEquivalenceLibrary. `adjoint` Return the adjoint of the unitary. `assemble` Assemble a QasmQobjInstruction `broadcast_arguments` Validation and handling of the arguments and its relationship. `c_if` Set a classical equality condition on this instruction between the register or cbit `classical` and value `val`. `conjugate` Return the conjugate of the unitary. `control` Return controlled version of gate `copy` Copy of the instruction. `inverse` Return the adjoint of the unitary. `is_parameterized` Return True .IFF. `power` Creates a unitary gate as gate^exponent. `qasm` Return a default OpenQASM string for the instruction. `repeat` Creates an instruction with gate repeated n amount of times. `reverse_ops` For a composite instruction, reverse the order of sub-instructions. `soft_compare` Soft comparison between gates. `to_matrix` Return a Numpy.array for the gate unitary matrix. `transpose` Return the transpose of the unitary. `validate_parameter` Unitary gate parameter has to be an ndarray.
