Instruction

class Instruction(name, num_qubits, num_clbits, params)

Generic quantum instruction.

Create a new instruction.

Parameters

• name (str) – instruction name

• num_qubits (int) – instruction’s qubit width

• num_clbits (int) – instruction’s clbit width

• params (list[int|float|complex|str|ndarray|list|ParameterExpression]) – list of parameters

Raises

CircuitError – when the register is not in the correct format.

Attributes

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

Methods

Instruction.add_decomposition(decomposition)	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
Instruction.assemble()	Assemble a QasmQobjInstruction
Instruction.broadcast_arguments(qargs, cargs)	Validation of the arguments.
Instruction.c_if(classical, val)	Add classical condition on register classical and value val.
Instruction.copy([name])	Copy of the instruction.
Instruction.inverse()	Invert this instruction.
Instruction.is_parameterized()	Return True .IFF.
Instruction.mirror()	For a composite instruction, reverse the order of sub-gates.
Instruction.qasm()	Return a default OpenQASM string for the instruction.
Instruction.repeat(n)	Creates an instruction with gate repeated n amount of times.
