UnitaryGate¶
- class UnitaryGate(data, label=None)[source]¶
Bases:
qiskit.circuit.gate.Gate
Class quantum gates specified by a unitary matrix.
Example
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
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.
- Parameters
data (matrix or Operator) – unitary operator.
label (str) – unitary name for backend [Default: None].
- Raises
ExtensionError – if input data is not an N-qubit unitary operator.
Methods
Add a decomposition of the instruction to the SessionEquivalenceLibrary.
Return the adjoint of the unitary.
Assemble a QasmQobjInstruction
Validation and handling of the arguments and its relationship.
Set a classical equality condition on this instruction between the register or cbit
classical
and valueval
.Return the conjugate of the unitary.
Return controlled version of gate
Copy of the instruction.
Return the adjoint of the unitary.
Return True .IFF.
Creates a unitary gate as gate^exponent.
The qasm for a custom unitary gate This is achieved by adding a custom gate that corresponds to the definition of this gate.
Creates an instruction with gate repeated n amount of times.
For a composite instruction, reverse the order of sub-instructions.
Soft comparison between gates.
Return a Numpy.array for the gate unitary matrix.
Return the transpose of the unitary.
Unitary gate parameter has to be an ndarray.
