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.
- 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
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.
- Raises
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 a decomposition of the instruction to the SessionEquivalenceLibrary.
Assemble a QasmQobjInstruction
Validation of the arguments.
Set a classical equality condition on this instruction between the register or cbit
classical
and valueval
.Copy of the instruction.
Invert this instruction.
Return True .IFF.
Return a default OpenQASM string for the instruction.
Creates an instruction with gate repeated n amount of times.
Replace blocks and return new instruction.
For a composite instruction, reverse the order of sub-instructions.
Soft comparison between gates.
Instruction parameters has no validation or normalization.
Attributes
