Gate

class Gate(name, num_qubits, params, label=None)

Unitary gate.

Create a new gate.

Parameters

• name (str) – The Qobj name of the gate.

• num_qubits (int) – The number of qubits the gate acts on.

• params (List) – A list of parameters.

• label (Optional[str]) – An optional label for the gate.

Attributes

Gate.decompositions	Get the decompositions of the instruction from the SessionEquivalenceLibrary.
Gate.definition	Return definition in terms of other basic gates.
Gate.label	Return gate label
Gate.params	return instruction params.

Methods

Gate.add_decomposition(decomposition)	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
Gate.assemble()	Assemble a QasmQobjInstruction
Gate.broadcast_arguments(qargs, cargs)	Validation and handling of the arguments and its relationship.
Gate.c_if(classical, val)	Add classical condition on register classical and value val.
Gate.control([num_ctrl_qubits, label, …])	Return controlled version of gate.
Gate.copy([name])	Copy of the instruction.
Gate.inverse()	Invert this instruction.
Gate.is_parameterized()	Return True .IFF.
Gate.mirror()	For a composite instruction, reverse the order of sub-gates.
Gate.power(exponent)	Creates a unitary gate as gate^exponent.
Gate.qasm()	Return a default OpenQASM string for the instruction.
Gate.repeat(n)	Creates an instruction with gate repeated n amount of times.
Gate.to_matrix()	Return a Numpy.array for the gate unitary matrix.
