qiskit.transpiler.InstructionDurations.get

InstructionDurations.get(inst, qubits, unit='dt', parameters=None)

Get the duration of the instruction with the name, qubits, and parameters.

Some instructions may have a parameter dependent duration.

Deprecated since version 0.19.0: Using a Qubit or List[Qubit] for the qubits argument to InstructionDurations.get() is deprecated as of qiskit-terra 0.19.0. It will be removed no earlier than 3 months after the release date. Instead, use an integer for the qubit index.

Parameters

• inst (Union[str, Instruction]) -- An instruction or its name to be queried.

• qubits (Union[int, List[int], Qubit, List[Qubit]]) -- Qubits or its indices that the instruction acts on.

• unit (str) -- The unit of duration to be returned. It must be 's' or 'dt'.

• parameters (Optional[List[float]]) -- The value of the parameters of the desired instruction.

Returns

The duration of the instruction on the qubits.

Return type

float|int

Raises

TranspilerError -- No duration is defined for the instruction.
