ControlFlowOp¶

class ControlFlowOp(name, num_qubits, num_clbits, params, duration=None, unit='dt', label=None)[source]¶

Bases : Instruction, ABC

Abstract class to encapsulate all control flow operations.

Create a new instruction.

Paramètres

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
duration (int or float) – instruction’s duration. it must be integer if unit is “dt”
unit (str) – time unit of duration
label (str or None) – An optional label for identifying the instruction.

Methods

`add_decomposition`	Add a decomposition of the instruction to the SessionEquivalenceLibrary.
`assemble`	Assemble a QasmQobjInstruction
`broadcast_arguments`	Validation of the arguments.
`c_if`	Set a classical equality condition on this instruction between the register or cbit `classical` and value `val`.
`copy`	Copy of the instruction.
`inverse`	Invert this instruction.
`is_parameterized`	Return True .IFF.
`qasm`	Return a default OpenQASM string for the instruction.
`repeat`	Creates an instruction with gate repeated n amount of times.
`replace_blocks`	Replace blocks and return new instruction.
`reverse_ops`	For a composite instruction, reverse the order of sub-instructions.
`soft_compare`	Soft comparison between gates.
`validate_parameter`	Instruction parameters has no validation or normalization.

Attributes

blocks¶: Tuple of QuantumCircuits which may be executed as part of the execution of this ControlFlowOp. May be parameterized by a loop parameter to be resolved at run time.

decompositions¶: Get the decompositions of the instruction from the SessionEquivalenceLibrary.
