ControlFlowOp

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

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.

Lève

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

• TypeError – when the optional label is provided, but it is not a string.

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.
