# UnitaryGate¶

class UnitaryGate(data, label=None)[source]

Bases: qiskit.circuit.gate.Gate

Class for representing unitary gates

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_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 Add classical condition on 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. mirror DEPRECATED: use instruction.reverse_ops(). power Creates a unitary gate as gate^exponent. qasm The qasm for a custom unitary gate This is achieved by adding a custom gate that corresponds to the definition of this gate. 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.
